milling Abstract The debranning process, essential technological step for removing the hulls in the case of covered cereals, is quite uncommon in “naked� grain processing. Nevertheless, numerous studies have been carried out on durum wheat varieties. These works thoroughly investigated the role of some technological parameters (processing time, hydration conditions of the kernels before processing, equipment scale, type of abrasive material) and the applicability also to samples with a high amount of starchy kernels. The results showed that this pre-milling operation was a useful tool for reducing the ash content and amylase activity of grains and, at the same time, increasing semolina yield of 3-4% points.

These positive effects were obtained only taking care that the Debranning Level (DL %) (i.e. the amount of material removed from 100 g dried kernels) was lower than 10%.

Pre-processing efficaciously reduced also the microbial contamination and the occurrence of DON, one of the mycotoxins more frequent in durum wheat. Thanks to the encouraging results obtained with durum wheat, attention is shifting to common wheat.

At this regard, DiSTAM researchers have been working on industrial scale debranning, demonstrating that the process can be successfully applied to this cereal too, re-

MILLING AND DEBRANNING TECHNOLOGY The main purpose of wheat milling is to remove the bran layers and, at the same time, reduce the endosperm region into smaller and finer particles [1, 2].

The flour production has evolved to a fully automated process since the use of the pestle and mortar; nevertheless, at present there are no significant technological innovations in this practice [3]. The entire milling process involves numerous specific operations and machines and relies on knowledge of the distribution and physical properties of the wheat kernel fractions: bran, endosperm and germ [4]. The endosperm includes the outer aleurone layer, which is removed with the bran during flour milling, and the starchy endosperm; in adTecnica Molitoria International - Yearly issue 2009 - 67

milling gardless of the hardness of the kernels. Also for common wheat was important to keep the DL lower than 10% in order to assure solely the elimination of bran layers, without loosing some endosperm materials (rich in starch) into the waste.

dition to the aleurone, the bran contains eight separate layers [5].

Debranning technology (also reported as pre-processing or pearling) has become well established in rice milling and barley processing to ensure the removal of hulls that have no technological and/or nutritional interest. In Southeast Asia, paddy rice debranning is performed by a simple husker that consists of two grinding disks made of cooked clay with abrasive grit: the lower is fixed and the upper is free to rotate. The paddy is fed between the disks and split [6]. In other debranning machines, the paddy rice gravity feeds down between rubber-surfaced rolls that are turning in opposite directions and at different speeds. The pressure between the two rolls is regulated by a pneumatic cylinder and can be varied in order to cause less breakage and to have a great efficiency of hull removal [7, 8].

Although this practice is necessary in the case of covered cereals, the sequential removal of the outer kernel bran layers prior to milling is quite uncommon in “naked� grain processing.

DEBRANNING OF DURUM WHEAT (Triticum durum L.) Several studies on the debranning of durum wheat have been carried-out since the nineteen-sixties, suggesting that this pre-milling operation is a useful tool for increasing yield and reducing the ash content of semolina [9-11].

But the first interesting results have been obtained since the nineteen-nineties, when the machines used for covered cereals were modified for pearling wheat kernels [12-15].

The original debranning systems for wheat are the PeriTec process marketed by Satake Corporation and the Tkac process [5]. This last system comprises two horizontal processing machines: the first one strips out the outer bran layers by friction (kernel to kernel), then, the 68 - Tecnica Molitoria International - Yearly issue 2009

latter removes most of the seed coats, some of the nucellar tissue and the aleurone cells by abrasion (kernel to stone surface) [12]. The PeriTec procedure also comprises two different machines, but with a vertical configuration; moreover abrasion comes before friction, as normally performed in the rice debranning process [5, 16].

In both processes, durum wheat kernels are initially conditioned with a small amount of water (normally 1 or 3% by weight) and processed after few minutes in order to assure that the water penetrates into the outermost regions of the seed coat. In this way, it is thus possible to facilitate bran removal, layer by layer and separately from the aleurone, by abrasion and friction actions [5, 12].

New debranning equipment for wheat has been developed that perform the abrasion and friction processes in the same machine. The Vertical Debranner VCW (Satake Corporation), for example, includes two separate working chambers within the same equipment: the upper chamber has an abrasive zone where rotating abrasive rings work the grain against a peripheral slotted screen, through which the outer bran layers are drawn. The partially debranned grains then enter the lower chamber, where friction completes the debranning process [5].

Applying the Tkac system to several durum wheat varieties, Dexter et al.

[17] showed an increase in the semolina yield associated with the removal of bran layers before milling; moreover,

the semolina obtained from debranned kernels presented a higher refinement, and the colour of pasta was consistently improved.

Interesting results were also obtained

by University of Milan researchers in collaboration with the C.R.A., Cereal Quality Research Unit of Rome [18-23]. In all, these studies thoroughly investigated the debranning of durum wheat by taking into account a number of technological parameters (processing time, equipment scale, and hydration conditions of the kernels before processing) and by testing wheat characterized by limited or high percentages of starchy kernels. The effects of the debranning action were evaluated by determining the Debranning Level (DL %, i.e. the amount of material removed from 100 g dried kernels) and observing the trend of several components (both for kernels and by-products) according to the DL. Using a discontinuous laboratory machine with an abrasive stone element, Pagani et al. [23] studied the effects of processing time within the range 30-180 seconds, on commercial wheat kernels, both at their native moisture content and after hydration with 3% water and a resting time of 5-15 minutes. In “dry conditionsâ€? (kernels at their original moisture content), both the ash content and Îą-amylase activity of grains decreased (fig. 1a). Nevertheless, after 120 seconds of treatment, corresponding to 12.8% DL, these positive effects were no longer present but, at the same time, the percentage of broken kernels Tecnica Molitoria International - Yearly issue 2009 - 69

strongly increased (fig. 1b). Since broken kernels negatively affect the milling performance and economic value of durum wheat, DLs higher than 10-12% have to be considered unproductive. The data of by-products confirmed that a DL higher than 10% should be avoided because of the high accumulation of starch in the waste, thus indicating that the abrasive action also concerned the endosperm region (fig. 1c).

When a brief “wetting” step of kernels was applied, all time treatments being equal, the debranning of the hydrated mass promoted a higher DL but a lower starch quantity in the by-products; at the same time a lower percentage (about 2.5% points) of broken kernels was observed [23] (tab. 1). As in the milling process, the pre-hydration of kernels made the tegument layers less crumbly, allowing a more regular and homogeneous removal of the bran layers.

Moreover, hydration assured a higher mechanical resistance in the endosperm region, as demonstrated by the lower starch amount in the corresponding byproducts. Hydration times longer than 15 minutes provided no advantage as water quickly moved into the endosperm region, leaving the bran layers dry. Also, the use of water quantities higher than 3% is inefficacious as it induced “clumpiness” and a partial swelling of grains, making their flowing and feeding into the machine difficult.

Milling of debranned durum wheat grains (using the Bühler MLU 202 apparatus) promoted a higher semolina yield only in

case of DLs lower than 10%. The best results were observed in correspondence of a DL of 8.2%. The reduction of α-amylase activity associated with debranning assured the semolina a lower susceptibility to heat damage during pasta drying, as demonstrated by the furosine amount 15-20% lower than in reference spaghetti (tab. 2) [21, 23].

Debranning (60 seconds previous hydration with 3% of water) on a laboratory scale was also applied to durum wheat samples characterized by a different amount of starchy kernels [20], as summarized in tab. 3. Despite the considerable differences in the compactness of the endosperm, the DL did not exceed the threshold of 10%. As expected, the abrasive action promoted the decrease in ash content and α-amylase activity and an acceptable quantity of broken kernels

(tab. 4). Despite the lack of compactness and, consequently, the higher fragility of the endosperm, the starchy sample (Creso cv) seemed to “absorb” the mechanical stress associated with the abrasive action better than the vitreous and more compact samples.

The positive results of the laboratory scale trials were also obtained on Table 3 - Chemical and physical characteristics of durum wheat varieties with a different level of starchy kernels [20].

The abrasive elements consisted of 12 metallic wheels covered with superabrasive material. Debranning was carried out on two commercial durum wheat samples of different vitreousity. As summarized in fig. 2, the ash content and the α-amylase activity of debranned grains decreased by about 30% (both in vitreous and starchy sample) whereas the increase in amount of

72 - Tecnica Molitoria International - Yearly issue 2009

broken kernels was limited (less than 10%). Other interesting results were obtained concerning semolina characteristics; in fact the yield increased 3 or 4 points for treated grains, provides that DL was inferior to 10%. Moreover, semolina refinement, and in particular the strong reduction (more than 30%) of α-amylase activity of semolina from starchy grains, provided a greater reduction of heat damage of pasta.

As most of the microorganisms present in cereals are located on the surface of the kernel, pre-processing could also represent a useful tool for efficaciously reducing microbial contamination [24] and the occurrence of mycotoxins. Regarding this problem, Aureli and D’Egidio [25] evaluated the distribution of deoxynivalenol (DON) in the milling fractions and spaghetti of three debranned durum wheat samples with different levels of contamination. The debranning process determined a considerable re-

duction of DON amount in the kernels compared to the native samples and a higher level of DON in the bran fraction (fig. 3). Spaghetti from debranned grains showed a lower DON amount (fig. 4); the reduction was significant only for the

sample with the highest level of DON contamination.

Debranning is now widely used in Italian durum wheat mills thanks to the benefits obtained on the characteristics of the kernels and the semolina.

milling DEBRANNING OF COMMON WHEAT (Triticum aestivum L.) Thanks to the encouraging results obtained by a number of research groups all over the world with durum wheat, attention was shifted to common wheat.

In 2001, Sugden [2] suggested that debranning makes white flour extraction easier than with conventional milling and increases flour yield. Furthermore, other advantages could be observed in flour, such as a lower ash content, a decrease of Îą-amylase activity, a reduced protein loss across the mill, a beneficial performance in gluten bread making, and a reduction in herbicide, pesticide, and bacterial contamination.

Nevertheless, the results obtained until now for common wheat are limited and contradictory. In 1994, in applying the Tkac system to several common wheat kernels, Dexter et al. [26] found inconsistent milling advantages over debranning. In fact, a modest improvement in flour yield and refinement was observed only in few samples. This behaviour could be explained by kernel morphology: the plump kernels with a shallow crease should be associated with a great efficiency of debranning technology [5]. Furthermore, kernel hardness plays a relevant role: durum wheat is very hard and resists penetration into the endosperm during debranning; on the other hand, the softer endosperm of common soft wheat can offer a lower resistance to mechanical penetration [5]. For all debranned wheat grains, an 74 - Tecnica Molitoria International - Yearly issue 2009

improvement of flour strength useful for some baking processes was obtained.

According to Dexter and Wood [5], this result was explained by the reduction in germ contamination of flour, due the removal of the germ into the preprocessing by-products; the germ, in fact, contains enzymes and sulphydryl compounds that induce dough weaking [5, 26].

Pearling of common wheat was also tested for reducing Îą-amylase activity, making the sprouted wheat kernels suitable for baking processes [27-29]. During the initial stages of cereal germination, in fact, the embryo and the aleurone layer are sites for the synthesis of Îą-amylase activity [27]. Recently, Hareland [29] observed that flour from debranned wheat was characterized by a higher Falling Number than the corresponding product from conventional milling. Moreover, he also found that the loaf volume and crumb characteristics of bread obtained from sprouted and treated wheat were not significantly different from those obtained from sound grain.

Sekhon et al. [30] proposed the debranning process for overcoming the negative effects of Karnal bunt (Neovossica indica) disease on the quality of wheat and its products. In this case, the debranning process followed by washing produced an enhancement in the yield and the quality of the flour, due to the decrease in proteolytic activity, total phenol, free fatty

acids, and trimethylamine content associated with bunt infection; these results made it possible to produce good-quality bread incorporating a small percentage of flour from treated wheat.

Finally, debranning technology was also used for investigating the distribution of microbial contamination in wheat kernels [24]. The positive results were generally obtained using a laboratoryscale machine and adopting pre-fixed debranning conditions [24, 27, 29, 30].

DiSTAM researchers, on the contrary, are working on industrial scale debranning of common wheat (hard and soft wheat) varieties in order to verify the possibility of applying this process to flour production. Three debranning machines, similar to those used for durum wheat (fig. 5) had been put in series in the industrial milling diagram of a mill company working 220 t/die. The abrasive elements were characterized by a superabrasive material of fine particle size (<1,000 mesh).

In order to test the repeatability of the process, debranning of commercial common wheat was repeated four times, both for hard and soft wheat [31]. All pearled kernels were characterized by DL equal to or lower than 10%,

milling confirming that only the bran layers were stripped away, without nicking the endosperm region (fig. 6a), as demonstrated also by the images obtained

by Fluorescence Microscopy (fig. 7).

Good results and repeatability were also observed for the amount of starch in the waste (fig. 6b); the absolute values never reached 10% (d.b.). The starch losses were very close to those found for bran coming from a conventional milling process [32] and confirmed that

the debranning did not engrave the endosperm.

According to previous studies on durum wheat [23], debranning carried out on homogeneously hydrated grains fragmented only the broken kernels already present in the unprocessed wheat, determining a reduction in size (<1.5 mm) and allowing their passage through the slotted screen into the waste. In fact, a general decrease in the amount of broken kernels was observed for all samples (data not shown).

CONCLUSIONS The results of research concerning the debranning of durum wheat kernels, carried out at DiSTAM in collaboration with C.R.A., highlighted the numerous and different advantages (i.e. increase in semolina yield, higher semolina refinement, reduction of microbial contamination and occurrence of mycotoxins) due to the application of this pre-processing, regardless the vitrosity of grains. These positive effects appear strictly influenced by the pre-treatment conditions: a preliminary and short hydration of kernels is determinant to assure debranning levels lower than 10%.

This threshold must not be exceeded

in order to have an acceptable percentage of broken grains during processing and avoid a negative loss of starchy endosperm into the waste.

Our studies exhibit that the debranning process can also be successfully applied to common wheat, regardless of the hardness of the kernels. Other investigations need to demonstrate that the increase in flour yield is associated with an improvement in flour technological properties.

durum Abstract A growing attention is noticed by consumers and producers about organic farming products; among these, cereal based products play a primary role. The aim of this survey is to provide knowledge about safety and quality aspects of durum wheat varieties grown with organic cropping system in Italy during four years (20042007). Analyses of deoxynivalenol (DON) and quality evaluation have been performed on samples of different durum wheat cultivars grown in several agro-climatic environments. The results obtained underline the importance both of the geographical field location and the climatic behaviour of the crop season on the mycotoxin level as well as on quality traits. The choice of cultivars suitable to different environmental conditions should be considered a very important tool to obtain satisfactory results.

INTRODUCTION The increased interest for organic products has been observed in Italy and particularly for cereal derived products (fig. 1).

In this context it is also evident the rising request of certified seeds for organic cropping systems (fig. 2).

Fig. 2 - Trend of employment (%) of certified seeds of durum wheat (ENSE 2008).

The organic approach, based on the soil fertility and on the utilization of organic compounds, appears to consumers able to ensure raw material healthier than the standard production. In organic cropping systems, which don’t permit the employment of chemical treatments for disease control, the safety aspects appear of great importance for grain producers and transformers. Fusarium spp. (i.e. F. culmorum and F. graminearum)

are the most common trichothecenesproducing fungi and deoxynivalenol (DON) or “vomitoxin” results one of the primary mycotoxins in wheat kernels, also associated to health problems in humans and animals (Miller, 2008; Pestka and Smolinski, 2005; Rocha et al., 2005).

It is well known that durum wheat (Triticum durum Desf.) represents the choice raw material for pasta production and consequently its quality characteristics (i.e. test weight, protein content, gluten quality, colour) are strictly related to the requirements of milling and pastamaking industries.

The aim of the present study was the investigation about safety and quality aspects of durum wheat grown with organic cropping systems in experimental fields in Italy. The survey was carried out within the National Project “BIOCER”, with the financial support of italian Agriculture Ministry.

MATERIALS AND METHODS Nine durum wheat cultivars (Ciccio, Duilio, Simeto, Iride, San Carlo, Claudio, Grazia, Creso and Cappelli) were grown over four years (2004-2007) in controlled organic crops management conditions in experimental fields located in the most representative areas for durum wheat in Italy.

The varieties were chosen on the basis of their diffusion (tab. 1) or for their particular traits. In the following figures the varieties were ordered according to the length of 80 - Tecnica Molitoria International - Yearly issue 2009

the growth cycle: early (E), mid-early (ME), medium (M), medium late (ML), late (L).

A randomized block design with 3 or 4 replicates was applied in all the environments. Grain samples from single replicates of each variety were grouped and the final pooled samples were employed for the laboratory analyses.

Grain samples were milled by CyclotecPBI (mesh size: 0.5 mm) and analysis of DON was carried out by enzyme-linked

immunosorbent assay (ELISA-Ridascreen DON, R-Biopharm) with a detection limit of 18.5 ppb. All data referred to mean of duplicated analyses and differences between replicates were ≤10% (CV). With the aim of a more detailed evaluation of levels of contamination, data related to DON are reported considering the following climatic areas: North, Centre East, Centre West and South.

The quality characterization has been performed by the main used chemical and technological analyses: test weight, protein content (Dumas-Leco combustion method), Gluten Index (UNI 10690 method), alveographic test (UNI 10453 method), yellow index (Minolta Chromameter CR-300). Semolina obtained by a pilot milling plant (Buhler MLU 202) was also used to produce pasta samples (spaghetti shape, ∅ = 1.65 mm) employing a low temperature drying diagram (Tmax 50°C). Pasta cooking quality was evaluated by sensory analysis according to D’Egidio et al. (1993). Analytical data are referred to mean of repeated analyses and differences between replicates were included within the specific ranges of each method. Moreover the results related to the quality aspects were expressed as average values of varieties in the three main macro-areas considered (North, Centre and South) during four years of experimentation.

RESULTS AND DISCUSSION Safety aspects The data concerning the DON analysis show a general low level of contamination (maximum value: 467 ppb) which results below the limit of 1,750 ppb in unprocessed durum wheat fixed by EC Commission Regulation n. 1881/2006).

In fig. 3 the mean levels of DON in positive samples over four years have been reported: in the geographical ar-

eas considered it can be observed the greater level of the mean values of DON in Northern areas respect to the other ones, with the exception of cultivar San Carlo; the greatest level of DON is 427 ppb (cv. Claudio) in Northern area, 467 ppb (cv. Duilio) in Central Eastern area, 368 ppb (cv. Simeto) in Western area and 290 ppb (Ciccio) in the Southern one. The minimum values (19 ppb) are detected in Central Eastern area for cvs.

Data concerning the incidence of contamination (fig. 4) show a general lower grade for all the varieties in Southern areas; the highest average value is 53% (cv. Duilio) while the minimum of 28% refers to cultivar Creso. This last variety shows the minimum incidence of contamination in all areas considered with exception of the South.

The low grade of DON contamination in the considered period (2004-2007) could be also due to the climatic conditions not Fig. 4 - Incidence % of DON contamination of durum wheat cultivars in different agroclimatic areas.

favourable to the developing of Fusarium Head Blight (FHB) and to the consequent DON production and accumulation.

Quality aspects With regard to the agronomic performance, data concerning the results of average production are reported in fig. 5.

The highest yields have been found in the North area (4.48 t/ha) and the lowest in South area (3.33 t/ha); the production levels obtained are generally interesting for organic crops. Among the cultivars,

Claudio has reached the best production, while Iride has been highlighted especially in the North; the production of the old variety Cappelli has been quite poor owing to the plant height and the tendency to lodging.

The average values of test weight has been recorded quite similar in all environments. Among the cultivars it can be noted that Ciccio, San Carlo, Claudio, Grazia and Creso reached the highest values, although all the cultivars presented levels above 80 kg/hL, considered a good value for the durum wheat grading (UNI 10709) (fig. 6).

Regarding quality traits, protein content appears to be a critical parameter in organic conditions because the absorption and the availability of nitrogen is considered an essential factor for the organic crops. An average value above 12.0% has been recorded in the three environments: the best results (average

value 12.7%) have been obtained in South Italy, a suitable agro-climatic area for this cereal. Relevant differences have been detected among the genotypes (fig. 7): Cappelli had the highest protein content, owing to the lowest production level; San Carlo, Creso and Simeto appeared the varieties having a protein level equal or higher than the average value of environment, while Iride has been the cultivar showing the lowest level of proteins in all the trials.

The rheological characteristics has been evaluated by different methods, widely used in the technological sector, (SDS, Gluten Index, Alveographic test), that are related to each other, but that also express different properties; therefore, a joint evaluation provides a more complete information.

The results of the SDS test have shown similar average values in all environTecnica Molitoria International - Yearly issue 2009 - 83

ments (fig. 8) while in South Italy the highest value has been detected. The cultivars have maintained the same order of sedimentation levels in all agroareas, even if with different values: San Carlo should the highest level.

The Gluten Index has not had remarkable differences between the environments and all varieties have shown good values with exception of Cappelli (fig. 9).

However, since low levels of gluten content can provide an overestimate

of Gluten Index values (Dâ&#x20AC;&#x2122;Egidio et al., 2008), different methods should be jointly considered in order to reach a right evaluation of varietal performance.

Alveographic parameter (W) showed averaged levels not particularly high in all environments (fig. 10); the best values have been in South Italy (average 140) and among the cultivars for San Carlo.

among the environments (Mariani et al., 1995). Therefore, the choice of cultivars suitable for specific agro-climatic environments represents a power tool to obtain raw materials having a suitable qualitative levels for the industrial requirements.

The semolina colour, expressed as yellow index, showed significant differences between the varieties, as expected for the strong genetic inheritance of this character; the cultivar San Carlo showed the highest values in all environments (fig. 11). Considering the levels required by pasta-making industry, the average values in the agro-climatic areas were not high, but it need to be underlined that the colour has not been considered in the breeding programs in the past time. Therefore several va-

rieties of not recent constitution donâ&#x20AC;&#x2122;t show remarkable yellow index level.

Better results has been generally recorded in Southern area than in Centre and Northern areas confirming findings of Johnston et al. (1983) about the positive influence by warm and drought environments on the carotenoid pigments.

Pasta cooking quality evaluation has not shown significant differences reaching always a medium quality (fig.

12). However it can be noted that the protein content and gluten quality did not reach high levels in this experimentation and that these two parameters play a primary role in determining pasta quality, mainly when low temperature drying cycles were applied (Dâ&#x20AC;&#x2122;Egidio et al., 1990).

Tecnica Molitoria International - Yearly issue 2009 - 87

durum CONCLUSIONS The results obtained give a clear indication about the role of the environmental and local conditions in determining the occurrence of DON in wheat. Therefore the choice of suitable sites in organic approach appears to be an important factor to prevent the DON contamination.

However further studies are required for the evaluation of the susceptibility of the durum wheat cultivars both against to the FHB disease and related mycotoxins accumulation.

Regarding the quality traits, protein level is the main factor to be improved for durum wheat from organic cropping system.

However, a suitable choice of cultivars can provide higher guarantees, without added costs, in order to reply to industrial requirements for products of high quality.

The cultivation of organic durum wheat in suitable agro-climatic areas is able to produce raw material responding to criteria of health and quality. The nonuse of chemical products revealed unsatisfactory production level only for some unfavourable year and environment. Even if it results more difficult to ensure regularly good protein levels, the use of modern varieties of good quality can provide raw material suitable for the requirements of pasta making industry when correct rotations are applied.

Foods having high level of safety and quality are more and more demanded by consumers; in this contest organic products could be better appreciated with an enhanced traceability along all the production chain.

pasta Abstract In this paper a chain model for organic durum wheat pasta was presented; in particular, the variety and grain processing technologies more appropriate for improving the end product qualitative traits were assessed. The durum wheat varieties were selected through agronomical trials in that demonstrated to be well adapted to the organic farming in the chosen growing area. The pasta products, particularly suggested for the short production and distribution systems, were obtained by using a single durum wheat variety. Two milling systems, which allowed to produce semolina (19.7% particle-size distribution <180 mm) and “semolato” (10.6% with particle-size distribution <180 mm), and two drying temperatures (50° and 80°C) during the pasta making process were also applied. As regards the global cooking value, the qualitative aspect more important for pasta consumers, the “monovarietal” pasta samples obtained from sufficient to optimum assessments in relation to raw materials (semolina or “semolato”) and drying temperature diagrams utilized; as matter of fact in comparison with semolina, the use of “semolato” and 80°C drying temperature allowed to produce pasta having the best cooking quality. In the paper the opportunity for increasing the market value of organic pasta through label transparency about durum wheat variety identity as well as applied processing was discussed.

INTRODUCTION In the last years the demand of organic foods at worldwide level has been continuously in growth and, at present, organic farming is one of the fastest-growing segments of Europe and United States agroindustry (Lu et al., 2005). As it is well known Italy, leader in Europe for organic food production and export, is in the higher world positions for organic cultivating area which, currently, is more than one million hectares with about 51,000 operators involved in the sector (SINAB and IFOAM data).

Research has an important role in growth and progress of organic agriculture; the development of this agriculture practice, preserving the natural resource base, determines, in fact, the need of on-farm survey and experimental reTecnica Molitoria International - Yearly issue 2009 - 89

pasta search to increase the knowledge and transfer to the farm. To this aim recent research has been carried out within the main institutions (also the Italian Ministry of Agriculture, MIPAAF, financed a group of research projects, covering the main crop chain) by exploring the first problem areas in organic agronomic conditions.

Within the projects financed by MIPAAF, in the cereal sector the research focused on the critical aspects of wheat organic growing i.e. yield, resistance to biotic and abiotic stresses, organic management in terms of nitrogen fertilizer and agricultural techniques. Specific attention was also paid to investigate on agronomical systems suitable for improving the quality and safety characteristics of durum wheat raw material. In this context, considering that in organic farming synthetic inputs cannot be applied and the permitted substances (organic fertilizers, natural pesticides) can be uneconomical in the long-term period, the research explored the biodiversity management as suitable strategy to safeguard organic production qualitative traits. Research aimed to test specific cultivars for such agricultural system i.e. variety characterized by a high efficiency in the use of nitrogen, resistant to pests and diseases, suitable for yielding grain with high qualitative traits. In this aim, at present, organic farmers often prefer cultivars which are selected and adapted to local specific conditions (soil, climate and production system), since the availability of organic varieties is scarce, i.e. varieties selected through breeding programmes for sustainable and organic 90 - Tecnica Molitoria International - Yearly issue 2009

production systems; moreover, the local breeds generally show higher performance as regards the nutrient use efficiency under organic agronomical conditions.

Data from field trials carried out in this project for three years under different organic practices allowed to evidence the factors which can affect the quality product performance and, on the other hand, demonstrated as an adequate control of some limiting factors could permit to improve the quantitative and qualitative aspects of durum wheat organic production.

This paper presents additional results in order to furnish further indications to improve the chain of organic pasta products; in particular, the use of a single high quality durum wheat variety to introduce the “monovarietal” brand in the label and increase the market value of the end product is discussed. The actual presence on the market of “monovarietal” pasta is limited; the pasta industry, in fact, prefers to use semolina blends that guarantee homogeneity and stability to product quality characteristics. Organic pasta production with “monovarietal” brand, responding to the main reasons for organic food consumer – i.e. perception of natural and safe raw material, good organoleptic attributes, adequate whole process information (Schmid et al., 2004; Midmore et al., 2005) – could favour the increase of organic pasta consumption both for occasional and regular organic buyers as well as provide a new market opportunity for farmers and for the other organic channel actors.

THE STANDARDS FOR THE DEVELOPED CHAIN MODEL The raw material The durum wheat chain model was developed in a South Italy area particularly devoted to durum wheat production.

Agronomical trials carried out during three years (2004-2006) in the identified area (Foggia, Puglia) allowed to identify some genotypes responding to the research objectives, i.e. showing good performance under organic farming (sufficient grain yield and good quality raw material); in particular, two durum wheat cultivars, constituted in the years 80-90th and, at present, scarcely cultivated, were chosen for the following process steps; the two cultivars were very adapted to South Italy area where the trials were carried out and where usually provided good quality products under conventional management.

The two varieties, included into a group of 15 durum wheat genotypes, were screened for potentially high quantitative and/or qualitative traits among local breeds at present not cultivated or little spread, recent cultivars and varieties known for good quality grain production under hard agronomic and environmental conditions, too. The trials were performed in a certificated organic soil on chick-pea as previous crop; the nitrogen use efficiency was evaluated by comparing one trial with only N fertilizer residue of previous legume (applied N=0) and an other with additional organic N fertilizer (N=80 kg/ha) supplied in the shooting

stage. A broad range of variability and a different behaviour in N organic fertilizer use both for the quantitative and qualitative aspects of grain production were evidenced. Applied organic fertilizer increased the yield of 17%, on average, (N0=3.17, N80=3.71 t/ha) but the cultivar response significantly differed. In particular some genotypes were markedly favoured, as the yield increase was very significant, up to 32%. At N80 one out of the most productive varieties also furnished grain with the highest test weight (82.7 kg/hl). As concern qualitative traits, as expected, the applied N fertilizer promoted the qualitative response; in fact, at the highest nitrogen fertilizer rate all varieties generally showed better performance in terms of protein content and quality, the mean amount of protein being 13% d.m. The two chosen cultivars showed grain with the best qualitative potential in the three years owing to a higher ability in grain nitrogen accumulation and also differentiated for other qualitative traits more directly associated with durum wheat end quality, in particular the insoluble protein fraction (Sgrulletta and De Stefanis, 1989).

The added organic fertilizer favoured the cooking quality (Dâ&#x20AC;&#x2122;Egidio et al., 1982), on average the products had a good global cooking value but the cultivar response was different, the data allowing to evidence some optimum products.

pasta variability factors on yield and qualitative characteristics of organic products as well as the different behaviour of all the examined varieties are reported in De Stefanis et al. (2008).

The pasta-making process The two cultivars were successively grown in open field (organic certified soil) adopting the best identified agronomical conditions. The single variety grain was utilized for “monovarietal” pasta yielding and appropriate process conditions were applied in order to safeguard and enhance the product quality characteristics.

Milling In order to enhance the quality of raw material obtained from these varieties, the grain was processed by applying two different milling systems. In this aim the grain of both cultivars was milled in pilot plant for producing semolina (19.7% particle-size distribution <180 mm) and in semi-industrial milling plant for making “semolato” (10.6% with particle-size

distribution <180mm). As evidenced in tab.

1, in general terms the materials showed good qualitative characteristics; the protein concentration was about 11.6% d.m., in agreement with the Italian legislation (Regulation N. 187/2001) and Disciplinary for pasta production of Italian Association for Organic Production (AIAB, PT.07 Rev.01/2002); no significant differences were evidenced both between the two cultivars and the two milling systems. The gluten quality of semolina and “semolato” was in the medium class and one of the two cultivar showed better gluten quality performance. For both varieties the grain processing in “semolato” didn’t alter the visual aspect of materials but, as expected, in respect of traditional semolina caused an increase in the ash content (data not reported) that, however, resulted in agreement with the Italian legal limits provided for the “semolato” product (0.90-1.35% d.m., Regulation N. 187/2001).

The use of “semolato” with 80°C drying temperature in pasta making process gave the best results in relation to cooking test (tab. 1); in these conditions, in fact, both spaghetti presented optimum organoleptic properties (global cooking values: 76 and 78).

On the other hand the application of the same drying diagram on the semolina provided a lightly different response between the two cultivars (global cooking quality: 70 and 76). At 50°C drying temperature both semolina and “semolato” gave end-products of inferior quality, the experts classified these pasta with sufficient or good cooking value.

Pasta making process in semi-industrial plant The product suitability for organic market was verified by furnishing “semolato” from the two selected cultivars to the Pasta Industry (Fabbri Pasta Industry, Strada in Chianti - Firenze). In order to produce pasta (spaghetti shape), the technological process was performed in old traditional conditions at 35°C drying temperature

for a long time (64 h). Tab. 2 reports the qualitative traits of the pasta products obtained from a single durum wheat variety.

In general the chemical composition, i.e. moisture, protein and total lipid contents, was similar in both products. The ash content was higher than the traditional product, however it met the limits that the law provides for pasta manufactured with “semolato”, and the colour was quite similar to the pasta produced with whole semolina without alterations in terms of visual aspect (fig. 1).

pasta In relation to cooking quality characteristics in the table is reported the final value of the global cooking assessment obtained by averaging the score of three experts which on cooked pasta evaluated surface stickiness (amount of substances adhering to pasta surface), firmness (resistance to chewing) and bulkiness (high or low tendency of pasta to remain in a mass). As it is shown the

experts indicated a good global quality in particular by estimating the firmness to be optimum (data not reported). These results were confirmed by a consumer acceptance test carried out with a group of untrained consumers (about 30 volunteer consumers) and by a panel of expert tasters, which expressed a very good assessment on the sensory characteristics of both organic pasta (data not shown).

DISCUSSIONS This paper shows the possibility to produce good quality durum wheat pasta from organic agriculture by using appropriate identified standards. Data demonstrated that the qualitative differences between organic and conventional products could be overcome through an appropriate selection of raw material and process technologies.

Specific additional and certified labelling could ensure consumers about the whole product processing; label transparency about durum wheat variety identity and applied processing method could be an important strategy for organic food and, in particular, for organic pasta to guarantee a positive future development of this sector. In fact considering that low input agriculture and traditional food processing appear as systems that produce high quality foods, the suggested product, obtained with ecological production management and characterized through the durum wheat variety identity, could 94 - Tecnica Molitoria International - Yearly issue 2009

increase the interest of the consumers for organic food and, as a consequence, the benefits associated with a broader social and environmental goal (Winter and Davis, 2006).

On the basis of the results two local varieties, grown in organic conditions right with the identified area, provided grain whose good qualitative traits were further improved by “semolato” milling, such as they could be considered for yielding a new organic pasta product, “monovarietal semolato-spaghetti” having the quality attributes required from consumers. The “monovarietal” pasta production from local cultivars could be an interesting opportunity in that, overcoming the uniformity of products on the market and assuring specific certified characteristics, contributes to add value to organic durum wheat products favouring the competitiveness of this national food industry segment; pasta industry could increase the sales by furnishing differed organic products to the

market. Moreover the model of “monovarietal” pasta by using local varieties might represent a useful example for developing a durum wheat “short supply chain” which could benefit farmers from “in loco” organic grain contracting and consumers from end-product price lowering. In this context, in the future, it is desirable that the required traits for high value pasta production – high quality and stability of quality characteristics in the identified growing area – are

particularly considered in the durum wheat breeding of varieties suitable for organic and sustainable agriculture.

dough Abstract Mixing is a critical operation in dough processing. Because mixing itself is a complex combination of rotational, shear and elongational deformations, it has always been extremely difficult to understand dough mixing on a mechanistic level. Apart from that, a quantitative relationship between the type of deformation in the mixing and the resulting dough properties is still lacking. This paper reviews our main findings in this field. We focused on the effects of well-defined flow regimes on dough properties to gain a mechanistic insight in dough processing and concluded that simple shear flow and elongational flow influenced material quite differently.

In elongational flow, the material was stretched and largely deformed favouring the break-up phenomenon. Simple shear flow caused rotation of protein patches, which promotes colloidal aggregation and local phase separation. High shear rates induced break-up of gluten domains and development of a network without having a severe effect on a molecular scale. The results outlined that it is not the mechanical energy input, but the type of deformation applied that is of crucial importance in dough processing. Dough was rather process tolerant upon simple shearing suggesting clear opportunities for making dough processing milder. Theses findings shed a new light on the concept of under, optimally and over-mixing, and open up interesting possibilities for innovative mixer designs.

Key words: shear flow, dough, microstructure, processing

INTRODUCTION Dough is made by combining wheat flour, water and energy through mixing. Mixing is a critical operation in dough processing, because of its influence on microstructure.

The dough microstructure correlates closely with a large number of quality properties in the final processed food.

According to Bloksma and Bushuk (1988), mixing has three distinct functions in the development of the dough: distribution of materials, hydration, and energy input to develop a protein structure. Therefore, understanding the mixing process is an essential step towards optimising wheat dough development (Schluentz et al., 2000).

Mixing leads to stretching of glutenin particles, which induces unfolding and breakdown favouring intermolecular cross-links and the development of a continuous protein network (Amend and Belitz, 1991; Sutton et al., 2003). In this context, breaking and reformation of disulfide bonds through a thiol-disulfide interchange reaction seem to be important. Upon processing, some S-S bonds may break

96 - Tecnica Molitoria International - Yearly issue 2009

and be reformed leading to the formation of larger molecular size protein through interchain S-S bonds (Wrigley and BĂŠkĂŠs, 1999). In this respect the covalent S-S bonds are often considered as transient or reversible cross-links (Edwards et al., 2001), relevant for the stability of larger protein network structures (Lindsay and Skerrit, 1998; Peressini et al., 2008).

Dough development is recognised as a key requirement for bread production.

The concept of dough development related to changes in rheological properties is widely recognised. Most of the studies on dough have been on the relationship between mixing, dough rheological properties and breadmaking performances.

This relationship is important because of changes in gluten viscoelasticity during mixing and its importance for product quality. Depending on processing conditions, dough properties, such as viscoelasticity or gas holding capacity vary strongly. In practical terms, dough can be under-processed, optimally processed or over-processed (Hoseney and Rogers, 1990). Extensive work has shown that mixing rate and mechanical energy input must be above certain critical values to develop the gluten network and to produce a dough suitable for breadmaking purposes (Kilborn and Tipples, 1972).

Generally, an optimum mixing time or energy input has been related to optimum performances (Skeggs, 1985). At optimum mixing, dough is hydrated and developed to give the maximum resistance to extension. Continued mixing of dough past the optimum causes a progressive

decrease in elasticity and increase in stickiness, which depend on flour composition (McRitchie, 1992). Also the gluten network becomes disrupted at prolonged mixing times (Peighambardoust et al., 2006).

Flours with a larger dough strength are more process tolerant, which makes it easier to obtain optimal dough mixing.

This fact explains why much cereal research is focused on making dough more process tolerant through techniques such as genetic cross. High dough strength has been target as a desirable quality characteristic in many breeding programs (Dexter and Marchylo, 2001).

Remarkably, only a few studies focus on improving the process. Instead of making the dough more process tolerant, another approach could be to make the process milder for the dough. Actually, it is remarkable that mixers are used to form a gluten network, because its formation relates to a kind of phase separation of the starch and gluten. In other words, a certain extend of demixing is necessary to create a gluten network. So, from theoretical considerations, it can be expected that mixers are not the optimally process equipment for making a good dough.

Recent research by Peighambardoust et al. (2006; 2007) and Peressini et al. (2008) show that clear opportunities exists for making dough processing milder. They concluded that the mixing energy is not the important parameter, but the actual deformation put onto dough. This finding also sheds a new light on the concept of under, optimally and over-mixing.

dough Energy input and flow patterns The energy (often indicated as Specific Mechanical Energy, SME) transferred to the material during a mixing process can be expressed as:

with Ď&#x2030; being the rotation speed (s-1), m the mass of the material filled in the mixer, M(t) the torque at time t (Nm), and tf being the total processing time (s). In this equation, SME had the units kJ/kg. It is clear that SME is a lumped parameter, and does not contain any details about the flow patterns inside a dough mixer.

The main question that now arises, is whether it is important how energy is transferred to the dough.

Answering this question requires a detailed study of the complex time-dependent flow and deformation pattern of the material inside the mixer during processing. Such a study could extract the main deformation characteristics. Generally, three main types of flow can be distinguished in real processes: purely elongational flow, shear flow and rigid body motions (rotation) (Jongen et al., 2003).

From the latter study, it could be derived most material is deformed in a simple shear like matter, but a small part of the material is elongated (especially between the mixer blades, and when pressed through the narrow space between the blades and the barrel of the mixer).

Simple shear flow and elongational flow influence material quite differently. In emulsions, it is well known that breakup of the dispersed phase is favoured by elongational flow (Walstra, 1983).

Simple shear flow generally is more important for coalescence of the dispersed phase (Habeych et al., 2008). It seems therefore likely that a dough that is developed with elongational deformation only will differ from a dough processed using shearing at comparable energy inputs. Because mixing itself is a complex combination of rotational, shear and elongational deformations, it has always been extremely difficult to understand dough mixing on a mechanistic level. An approach therefore is to simplify mixers in such a way that only one flow pattern is dominant. A summary of those studies is given in the next section.

The effect of well-defined deformation on dough properties Mechanistic insight into the dough preparation process might be improved through the application of well-defined deformation. However, a prerequisite is that com98 - Tecnica Molitoria International - Yearly issue 2009

parable mechanical energy input and shear stress are applied when analysing the mixing process in terms of well-defined shear and elongational deformations.

The effects of well-defined deformations on dough properties were studied by several authors (Campos et al., 1997; Lee et al., 2001; Schluentz et al., 2000). Lee et al. (2001) used a conventional rheometer to conclude that simple shear or elongational deformations did not produce dough quality (judged by the amount of protein matrix) when compared to that produced by a z-blade mixer. However, energy amount input was much lower than energy input of a z-blade mixer.

Consequently their results are difficult to interpret, which makes comparison with commercial processing difficult.

Van den Einde et al. (2003) and Peighambardoust et al. (2004) introduced a new method based on a pilot-scale shear cell, which applied high shear stresses (up to 50 kPa) and specific mechanical energies (SME, up to 400 kJ/kg) comparable (and even above) to those used during industrial dough mixing and extrusion. Peighambardoust et al. (2004) used a well defined shearing treatment and obtained pasta-like products with acceptable properties in terms of cooking loss, swelling behaviour and product firmness, suggesting the formation of a continuous gluten network.

Another study was focussed on the effect of simple shearing flow on the physical properties of gluten at a more structural level (Peighambardoust et al., 2006; Peressini et al., 2008). Main focus was on its most functional part, the glutenin macropolymer fraction (GMP).

The effect of simple shear flow was compared with z-blade mixing at similar levels of energy input. Processed dough was investigated at different length scales using various techniques (tab. 1). Mixing led to the formation of a continuous gluten network surrounding starch granules, whose typical size was rather small (fig. 1D1). Prolonged mixing induced extensive breakdown of gluten network (over-mixing), resulting in a homogeneous dispersion of proteins into the dough (Peighambardoust et al., 2006). When the dough was mixed in a z-blade mixer, the amount of GMP decreased sharply upon processing (fig.

2) (Peighambardoust et al., 2005; 2006).

In addition, the dough lost its strainhardening properties and became sticky upon prolonged mixing (tab. 2).

Simple shear processing transformed the relatively homogeneous dough into a rather heterogeneous material as a re-

Vermant (2001). Compared to mixing, gluten formed very large structures. Recent results showed that the shear rate could be used to control the gluten domain size (Peressini et al., 2008). At low shear rate of 7.4 s-1, the gluten domains were clearly visible by eye, suggesting that the domains were at least several millimetres in diameter (fig. 1A1). CSLM images of sheared dough at 37 s-1 showed the loss of large gluten patches and the transition from a heterogeneous to a more homogeneous protein distribution in which starch granules are embedded (fig. 1C1). In order to better understand the effect of shearing, we studied the changes in the very highly aggregated glutenin fraction GMP. Shearing did not lead to appreciable changes in GMP content increasing processing time or shear rate (fig. 2 and 3) (Peighambardoust et al., 2006; Peressini et al., 2008). The difference in GMP-content at SME=0 could be explained by the fact that in case

Fig. 3 - Effect of simple shearing at different shear rates on GMP content of doughs.

of mixing, flour was used and in case of shearing zero-developed dough. This leads to a difference in GMP-content. In contrast to mixing, simple shearing preserved strain hardening regardless the process intensity (time) (tab. 2). Gluten network formation by shear did not imply molecular breakdown effects.

This approach showed that processing (shearing and mixing) influences the dough properties at various length scales (Peressini et al., 2008): - molecular and microscopic levels: glutenins form a network containing reversible cross-links. Such aggregates are mainly stabilised by disulfide bonds, while non-covalent interactions seem to be important for re-assemble of processed dough. Mixing causes detrimental effects at molecular level, while only slight changes are related to shearing (more tolerant process). The detrimental effects are reflected by a decrease in GMP and reduced strain hardening; - mesoscopic level: the wheat protein can aggregate through physical interactions when the dough is deformed (fig.

1A2). The final dough structure depends on the strength of those interactions and the deformation applied. We proposed a different mechanism for break-up of gluten domains during mixing and shearing. In case of shearing, it is more likely that the gluten domains are elongated and subsequently broken, without having a severe effect on molecular scale (fig. 1B2-C2). In case of mixing, the effect is indirect. During mixing, the dough is Tecnica Molitoria International - Yearly issue 2009 - 101

dough weakened due to changes at molecular level, which reduces its ability to form structures (fig. 1D2).

The use of simple shear flow in the case of dough leads to structures in dough that could not be obtained using mix-

ing conditions. Given that simple shear processing does not alter the vitality of gluten (as measured by GMP) and that no reorientation hinders the full assembly of gluten structures under flow explains the structure formation process.

NEW INSIGHTS IN DOUGH MIXING From the studies presented above, it is clear that the mechanical energy is not the sole parameter driving the dough development process. It seems that the type of deformation applied to the material during mixing strongly influences dough structure formation as well.

The importance of the actual deformation rate was already found by Don et al.

(2003) but not as such described. They found that different mixers (Mixograph mixer vs z-blade mixer) require different mixing energies to obtain optimally mixed dough. Also over-processing occurred at different levels of mixing input.

It seems that the pin mixer requires less energy to mix optimally, but can add more energy before over-processing starts to occur. Jongen found that different mixers provide different ratios of elongational flow and simple shear flow (Jongen et al., 2003). This hints in the direction that the effect of elongational deformation on dough characteristics is completely different from shear deformation.

Elongational flow stretches material, thereby favouring break-up. In case 102 - Tecnica Molitoria International - Yearly issue 2009

of gluten, mechanical forces induced by flow deformation even decreases the molecular weight, leading to a reduced ability to form gluten structures.

Simple shear flow causes rotation of protein patches, which promotes colloidal aggregation and shear-banding.

High shear stress induces break-up of gluten domains and development of a network without having a severe effect on a molecular scale. This can explain why dough is rather process tolerant upon simple shearing. Regions near the moving parts and the walls in a z-blade mixer have a pronounced shear flow.

The main elongational zone is in the upper part of the mixing cavity (Jongen et al., 2003). Also, a Mixograph has distinct zones with a different predominant flow.

The new insights described above can be used to give a new explanation for the concept of under, optimally and over processing of dough. Traditionally, the dough in a mixer is considered as a homogeneous material. However, it seems important to consider the local flow effects in a mixer. As shown above, a division should be made between

simple shear flow and elongational flow.

Simple shear flow seems necessary to create a gluten network. In other words, a minimum of simple shear deformation is necessary to obtain the gluten network. In principle, it seems that the longer the simple shear deformation is applied, the more connected the gluten network becomes. In mixers, the effect of simple shear flow is hindered by the occurrence of reorientation of the material inside the mixer, since it is likely that the formation of bonds necessary to form a gluten network takes some time.

As described above, simple shear flow only makes dough rather process tolerant. Therefore, the fact that mixers weakens the dough can be attributed to the presences of elongational flow.

The fraction of dough that passes a zone in which it is elongated becomes larger upon processing time.

Fortunately, dough has the unique capacity to repair molecular breakdown by creating new S-S bonds (Peressini

et al., 2008). Nevertheless, after a certain processing time, the dough becomes exhausted and starts to weaken. This effect limits the processing time. It is clear that a higher dough viscosity enhances the effect of breakdown, as the forces become higher in the system.

Now, we have two time dependent effects. For simple shear flow, longer processing time seem beneficial for network formation. The fact that upon processing, a larger fraction of the dough is weakened because of the elongation puts a limit onto the maximum processing time that can be applied. At short processing times, the role of the elongational flow will be limited, but the network has not be formed completely due to the limited total shear deformation applied. A long processing time leads to weakening.

Those two effects explain a optimal dough processing window. This window however is expected to be very mixer type-dependent.

CONCLUSIONS AND FUTURE PROSPECTIVES This paper present a new explanation for the concept of under, optimally and over processing of dough. The new insight relates the fact that a lumped process parameter, such as SME is not sufficient to explain the mixing behaviour. Local flow effects inside a mixer should be considered as well. It seems that simple shear flow is responsible for

gluten network formation and does not lead to break-up at various length scales in dough. Elongational flow seems the most important flow type to explain dough weakening. This new insight seems to create new possibilities to make a process milder for doughs by reducing peak stresses in the system, which are normally induced by elongaTecnica Molitoria International - Yearly issue 2009 - 103

dough tional flow. The insights presented in this paper could form a driver for new mixer design, thereby relaxing the need for process tolerant wheat flours. It is clear that the use of new mixers could also create new wheat flour applications and related product innovations.

IPM Abstract After harvesting and threshing, the wheat is usually taken to storage facilities in which it can be damaged by several insect and mite species. Knowing which species of pests and beneficial insects are present is important in developing and implementing the best insect pest management program.

Stored-product insects can be divided into three categories according to their feeding habits: internal feeders, external feeders, and scavengers.

Internal feeders usually complete development within a single kernel of grain. External feeders develop outside kernels, on damaged grain, grain debris, and grain products. The scavengers are unable to penetrate or feed on undamaged grain kernels. The most common and important internal grain feeders are Rhyzopertha dominica, Sitophilus granarius, S. oryzae and S. zeamais. For the external grain feeding insects, the most frequently encountered species are Plodia interpunctella, Trogoderma granarium, Cryptolestes ferrugineus, Oryzaephilus surinamensis, Tribolium castaneum, Tribolium confusum, and mites. Some insects also feed on mold mycelia, such as Alphitobius diaperinus and Typhaea stercorea. The request for pesticide residuefree raw materials on the part of leading industrial semolinamills induces grain managers to adopt an Integrated Pest Management (IPM) approach to avoid pest problems in commercial warehouses.

Management of stored HARD WHEAT PESTS Pasquale Trematerra University of Molise - Department of Animal, Plant and Environmental Science - Via de Sanctis 1 86100 Campobasso - Italy e-mail: trema@unimol.it Key words: hard wheat, pests, control, IPM

INTRODUCTION Stored-product insects and mites have a negative economic impact in three general ways: direct loss of biomass due to consumption of stored wheat; loss of product quality or value due to the presence of insects; and costs associated with preventing or treating insect infestations. It has been estimated that 5-10% of stored grain in developed countries and 35% of stored grain, or more, in developing countries is lost to insect damage.

For processed cereal products it is the contamination of food that is the major issue, rather than loss of food material due to consumption by insects. Stored-product insects and their fragments can indicate that the food is adulterated, cause a health hazard and provoke allergic reactions, produce excretions that change the taste of food, and potentially carry disease-causing microorganisms. Infestation of packaged commodities has a wide range of negative impacts including loss of customer good-will, damage to commercial brand identity, failure Tecnica Molitoria International - Yearly issue 2009 - 105

IPM to meet government regulations or pass plant inspections, and costs associated with handling of product returns and consumer complaints. If an insect is found in packaged food, consumers are not only hesitant to purchase the product in the future, but will also tell other consumers about their bad experience and thus compound the negative impact.

Inspection programs may look for the insects or signs of insect presence (trails left in dust, their silk, damage caused by insects feeding, insect fragments in flour, or hotspots). The costs of insect sampling and insect pest management also are economic losses that must be attributed to insects.

Effective management of pests within storage facilities of edible raw materials, such as hard wheat, is critical for maintaining an abundant, affordable, and safe food supply. However, the quality of the grain risks being compromised by the invasive action of animal pests, particularly insect species. The objective of stored grain management is to slow or deter this loss of quality so that grain can attain its highest potential market value. The food industry is sensitive to issues involving food quality and safety.

However, there is considerable variation within the industry in terms of the quality of pest management programmes, with some continuing to rely primarily on calendar-based pesticide treatments.

It is well-known that hard wheat is one of the most important staple foods. After harvesting and threshing, the wheat is usually taken to storage facilities in 106 - Tecnica Molitoria International - Yearly issue 2009

which it can be damaged by several species of moulds and pests, primarily several insect and mite species, but can be infested also by mice and birds. Knowing which species of pests and beneficial insects are present is important in developing and implementing the best insect pest management program.

Stored-product insects can be divided into three categories according to their feeding habits: internal feeders, external feeders, and scavangers. Internal feeders usually complete development within a single kernel of grain. Ovipositing females deposit each egg in a hole that they have bored into a kernel and then close the hole with a gelatinous plug, as in the Sitophilus weevils, or they may lay eggs outside the kernels, as in Rhyzopertha dominica and Sitotroga cerealella. In the latter case, the first instar larvae burrow into kernels. Internal feeders are primarily a problem in grain fields or in grain storage and processing facilities.

External feeders develop outside kernels, on damaged grain, grain debris, and grain products. They are often found in grain storages, processing plants, retail stores, and homes. The scavengers are unable to penetrate or feed on undamaged grain kernels. They lay their eggs and the larvae feed on dust and particles of food products, or on the kernels damaged by the internal or external feeders.

The most common and important internal grain feeders are Rhyzopertha dominica, Sitophilus granarius, S. oryzae and S. zeamais. For the external grain feeding insects, the most frequently encoun-

tered species are Plodia interpunctella, Trogoderma granarium, Cryptolestes ferrugineus, Oryzaephilus surinamensis, Tribolium castaneum, Tribolium confusum, and mites. Some insects also feed on mold mycelia, such as Alphitobius diaperinus and Typhaea stercorea.

The major biotic factors influencing insect abundance in cereals are the presence of internal grain feeders, the pres-

ence of fungi and the biochemical state of the grain. External feeders are rare in cereals undamaged by grain-handling equipment, but increase markedly with prior infestation by primary pests. The damage caused by internal feeders on whole kernels may facilitate colonization by secondary pests that continue to damage the cereals (Trematerra et al., 2000).

INSECT PESTS Internal feeders Rhyzopertha dominica (Fabricius) (Coleoptera) (fig. 1). R. dominica, the lesser grain borer, is thought to have originated on the Indian subcontinent, but is now cosmopolitan. Adults and larvae of R. dominica feed primarily on stored cereal seed including wheat, maize, rice, oats, barley, sorghum and millet. They are also found on beans, dried chillies, turmeric, coriander, ginger, cassava chips, biscuits and wheat flour.

There are several reports of the lesser grain borer being found in or attacking wood.

Sitophilus granarius Linnaeus (Coleoptera). Species of Sitophilus (S. granarius, S. oryzae and S. zeamais) can be identified using the keys of Gorham (1987) or Haines (1991).

S. granarius, the granary weevil, is distributed throughout the temperate regions of the world. In tropical countries it is rare, being limited to cool upland

areas. S. granarius is a frequent pest of wheat, and it can attack other cereals such as barley, maize, sorghum, rice and other cereal grains. Severe infestations can reduce stored grain to a mass of hulls and frass. Feeding damage by S. granarius can make grains vulnerable to attack by other pests which are unable to penetrate intact grains.

Fig. 1 - Rhyzopertha dominica.

Tecnica Molitoria International - Yearly issue 2009 - 107

IPM Sitophilus oryzae (Linnaeus) and Sitophilus zeamais Motschulsky (Coleoptera) (fig. 2). S. oryzae, the rice weevil, and S. zeamais, the maize weevil, are found in all warm and tropical parts of the world, but S. oryzae may also be found in wheat stored in temperate climates. S. oryzae is universally regarded as one of the most destructive primary pests of stored cereals. It does not often breed in non cereal foods, although it does attack split peas and pasta. It can attack cereal plants in the fields. Voracious feeding on whole grains by these insects causes in weight losses, fungal growth, quality loss through an increase in free fatty acids and it can even completely destroy stored grain in all types of storage. Invasion by this primary pest may facilitate the establishment of secondary insect and mite pests and plant pathogens.

Trogoderma granarium Everts (Coleoptera) (fig. 3). T. granarium, the khapra beetle, is believed to have originated in India. It is especially prevalent in certain areas of the Middle East, Africa and South Asia, and is also found in certain specialized warm habitats in temperate countries. T. granarium does not appear to be established in South-East Asia, South America, North America, or

Plodia interpunctella (H端bner) (Lepidoptera). P. interpunctella, the indianmeal moth, is common in warm climates. In hot tropical climates, it is often more prevalent in cooler areas, such as highland regions. In cool temperate countries it can survive in heated buildings. P. interpunctella attacks stored grains (in which it eats the embryo), milled cereal products, nuts, spices, peas, beans, lentils, chocolate and other commodities. In many countries P. interpunctella can cause serious infestations

108 - Tecnica Molitoria International - Yearly issue 2009

Australia. The larvae of khapra beetle are serious pests of cereal grains and oilseeds. The adults rarely, if ever, eat or drink. In bag stores, the first signs of infestation are masses of hairy cast larval skins, which gradually push out from the crevices between sacks. Massive populations of the insect may develop and grain stocks can be almost completely destroyed. T. granarium in many countries have specific quarantine regulations against possible importation, it is an A2 pest in the Euro-Mediterranean region (EPPO/OEPP 1996).

Cryptolestes ferrugineus (Stephens) (Coleoptera) (fig. 4). C. ferrugineus, the rusty grain beetle, is cosmopolitan, with a wide range extending from the tropics to temperate regions. It is more cold tolerant than other species of Cryptolestes, and can survive winter in temperate climates. Cryptolestes infest a variety of cereal grains and other types of food. In grain, the embryo is often attacked, with the larva penetrating under the pericarp and completing development while consuming the embryo. It is an important secondary pest of cereal grains, often following infestation by other insects.

In addition to C. ferrugineus, C. pusillus is sometimes referred to as the “flat grain beetle” or “bran beetle”. The 2 species have the same colour, general morphology and size, although C. pusillus can often be slightly larger.

Oryzaephilus surinamensis (Linnaeus) and Oryzaephilus mercator (Fauvel) (Coleoptera). In the small family Silvanidae, only O. surinamensis, the saw-

Fig. 4 - Cryptolestes ferrugineus.

toothed grain beetle, and O. mercator, the merchant grain beetle, are of any importance as pests although other species such as Ahasverus advena and Cathartus quadricollis may be common in the humid tropics. Oryzaephilus spp. are not associated with significant weight loss in grains; however, infestations by these pests can lead to substantial contamination with frass and dead bodies. Thus, quality deterioration is an important issue. O. surinamensis, which is cosmopolitan, is a common secondary pest of cereals and cereal products; O. mercator, mostly found in warmer, temperate and tropical regions, is more common on oilseeds, though it is also sometimes found on cereals. Both are good invaders of packaged foods.

Tribolium castaneum Herbst (Coleoptera). T. castaneum, the red flour beetle, is cosmopolitan. Hosts include cereals, millet, wheat bran, flour, grain spillage, broken grains, grain products, mixed feeds, beans, peas, lentils, butter Tecnica Molitoria International - Yearly issue 2009 - 109

IPM beans, alfalfa seed, groundnut seed, and many other products. Both the larvae and adults of T. castaneum damage the host. They cause extensive damage to grains already damaged as a result of handling during harvest, holed grains, and those damaged by other pests. The larvae of T. castaneum feed primarily on the germ of the cereal and render the damaged grains unfit for sowing. T. castaneum not only reduce the germination of wheat grains, but also contaminate the wheat. When infestation is severe, these products turn greyish-yellow and become moldy, with a pungent odour.

Repeated consumption of contaminated material constitutes a health risk to both humans and livestock; toxic symptoms were probably due to defensive secretions of benzoquinone compounds produced by the insects. It is predaceous and cannibalistic.

Tribolium confusum Jacquelin Du Val (Coleoptera). T. confusum, the confused flour beetle, is believed to have originated in Ethiopia. It is cosmopolitan, but particularly common in temperate climates, and much less common than T. castaneum in most parts of the tropics. T. confusum is an important pest of

many commodities, especially cereals and cereal products, but also dried fruits, nuts, spices. It is predaceous and cannibalistic. Its economic importance is therefore similar to T. castaneum.

Mite pests Acarus siro Linnaeus (Acarina). A. siro, the grain mite, probably is distributed worldwise, although because of its physical requirements it is most common in temperate countries. A. siro dominates in post-harvest habitats ranging from farm stores to household larders, and at all points in the commercial chain between these two situations. Records other than of a cereal origin include meat, tea, spices, dried fruit and pulses. The major damage to whole cereal grains and other seeds is caused by the preferential attacks that mites make on the germ, which causes losses in germination viability. Odours build up in heavy infestations, caused by mitesâ&#x20AC;&#x2122; lipid secretions. Handling infested products can cause a contact dermatitis, respiratory allergy and asthma.

Closely related species are A. farris and A. immobilis that infest farm stored grains and cheese.

PEST MANAGEMENT The main differences between the onfarm and commercial stores were in their structural characteristics, the general hygienic conditions and control measures adopted against stored product pests; 110 - Tecnica Molitoria International - Yearly issue 2009

these factors seem to be highly relevant in determining the greater complexity found for the insect pest fauna in traditional storehouses compared to commercial facilities. The traditional granaries are

generally poorly constructed, and farmers are mostly unaware of safe storage practices, such as warehouse preparation for the reception of new products, the removal of old products, regular checks of the sanitary state of the warehouse, product control during the storage season and the application of quick and appropriate interventional measures against the emergence of pests. Consequently, these facilities also are frequent sources of stored pests for commercial warehouses where the grain is usually transferred for lengthy storage.

Pest control is most successful in commercial granaries (fig. 5), silos and large flat warehouses and is usually based on carrying out both preventive and curative measures in integrated stored product protection systems. However, in some commercial warehouses surveys conducted led to the discovery of numerous species of harmful insects, which may indicate poor storage conditions. Pest control in commercial storehouses is generally based on chemical treatments carried out by the use of fumigants or contact insecticides. Of these, the

Tecnica Molitoria International - Yearly issue 2009 - 111

IPM most important chemical products are the fumigants aluminium phosphide and magnesium phosphide. The fumigations are carried out several days after the grain is stored or when an infestation is detected by sample analysis. To prevent phosphine residues in grain bulk, the use of fumigants in bags is the preferred technique of fumigation. Furthermore, in some types of silos it is possible to apply a technique where gas is circulated inside the mass by means of a special fan that provides even gas distribution throughout the commodity. Regarding contact insecticides, several products containing pyrethrum extracts, pyrethroids or organophosphates are registered for use on cereals.

The request for pesticide residue-free raw materials on the part of leading industrial semolina-mills induces grain managers to adopt an Integrated Pest Management (IPM) approach to avoid pest problems in commercial warehouses. This type of approach in protecting stored grain includes both preventive and control methods, such as sanitation and structural maintenance, aeration, monitoring, alternative control methods and judicious use of effective chemical insecticides only when needed to avoid the economic impact caused by infestation.

In this sense, IPM techniques should be considered as tools in a toolbox: not all of them are needed every time, but they still need to be made available.

In commercial warehouses, sanitation procedures for empty storage facilities are usually carried out: storage structures 112 - Tecnica Molitoria International - Yearly issue 2009

are emptied of old grain and cleaned before storing the new crop; the structure is well sealed and repaired before harvest, especially the bin walls, roofs, doors and hatches; the grain handling equipment is kept in good condition; for additional protection against infestation, the inside surfaces of storage facilities are sprayed with residual insecticides 4-6 weeks prior to harvest.

Aeration is often used to cool stored grain and to prevent moisture migration when ambient temperature drops below that of the grain temperature. Prevention of moisture migration by maintaining a uniform temperature throughout the grain mass greatly reduces the possibility of mould development and insect feeding and reproduction. Aeration is generally obtained by passive airflow through the upper openings of the storage facility or by mechanically moving the bulk; only a few silos are equipped with fans.

Monitoring is recognized as an important IPM post-harvest procedure of stored grain. In particular, grain managers frequently monitor grain quality and temperature, but only in a few cases improved pest-monitoring procedures are developed and adopted. Sampling of insect pests is often limited to counting the number of adult insects in the wheat samples taken for the purpose of grain grading. Furthermore, only in sporadic cases traps are used to verify the presence of insect pests.

Considering the alternative methods to chemical control, not many techniques of physical control have been widely accept-

ed and carried out in storehouses. The main methods employed are modified atmospheres, especially based on carbon dioxide (CO2), and nitrogen atmosphere (N2) as well; low temperature treatments (chilled aeration) and inert dusts are also employed. These techniques, however, are carried out only for organic products that still are of negligible importance on the food market. Yet, despite the considerable number of possibilities for biological and bio-technological control of stored wheat pests, none of them is currently employed under practical conditions.

Besides pest management techniques, another critical factor affecting the potential growth of insect pests inside commercial wheat stores is commodity history before its arrival to the granaries. In many cases an infestation that has occurred in a traditional warehouse is transferred to a commercial facility

with the grain. Moreover, wheat is often transported by means of ships and trucks that usually carry many types of products and are not cleaned of potentially infested grain or debris. Finally, as farm production frequently amounts to a few tons, it is possible for a single storehouse to hold wheat that comes from many suppliers; consequently, the bulk can be entirely infested by pests arriving with a single grain load.

Good storage hygiene plays an important role in limiting infestation by insects and mites. The removal of infested residues from the previous seasonâ&#x20AC;&#x2122;s harvest is essential, as is general hygiene in stores such as ensuring that all spillages are removed and all cracks and crevices filled.

Infestations may also be limited by the storage of good quality grains such as whole cereals with fewer broken grains and dockage.

flour analysis Abstract In this work the quali-quantitative determination of arabinoxylans (AX) in cereal flours and meals was performed by the anion-exchange chromatography with amperometric detection (HPAEC-PAD). The proposed method allowed the determination of total and soluble AX and the assessment of the different distribution of arabinose and xylose in the AX chain with the possibility to evidence AX structural modifications.

Key words: cereal flour/meal, arabinoxylans, HPAEC-PAD

INTRODUCTION The most common source of dietary fibre is the outer layers and the endosperm cell walls of cereal grain (wheat, barley, oat, rye, etc.). The non-starch polysaccharides (NSP) found in mature cereal grain include the arabinoxilans (AX), which make up the pentosan portion of the insoluble fibre fraction.

AX consist of a backbone of xylose (xyl) residues to which arabinose (ara) residues can be linked at the O-2 and/or O-3 positions. Ferulic acid and other substituents can be coupled to the ara through an ester linkage.

In the wheat endosperm, AX are partially water extractable (â&#x2C6;ź30%), and ara/xyl ratio (A/X) of 0.6 is usually found, but a wide natural variability is observed (Cleemput et al., 1993; Dervilly et al., 2000); AX in the outer part of the endosperm are less substituted with ara than those 116 - Tecnica Molitoria International - Yearly issue 2009

from the inner one (Delcour et al., 1999).

Besides, AX originating in the aleurone layer and from inner pericarp, testa and nucellar tissue are characterized by lower A/X ratio (0.3-0.4) (Antoine et al., 2003).

AX, despite their low content (2-3% w/w) in wheat flour, have a strong impact on cereal technology and in the final products (Courtin and Delcour, 2002; Izydorczyk and Biliaderis, 1995).

These components, because of their partial water-extractability and functional properties, such as viscosity, gelation and water-binding capacity, may affect dough and breadmaking performances interacting with the gluten proteins (Michniewicz et al., 1991). AX are also important from a nutritional point of view with beneficial effect on the re-

duction of post prandial blood glucose (Lu et al., 2000) and cholesterol levels (Rieckhoff et al., 1999). In addition AX and beta-glucans have prebiotic effects (Charalampopoulos et al., 2000; Grasten et al., 2003).

AX assessment is usually carried out by spectrophotometric methods: phloroglucinol method (Douglas, 1981) and orcinol-HCl method (Hashimoto et al., 1987).

These methods don’t give any information about the structure of AX chain and are also affected by sugar interferences.

In this work, operating conditions of an HPAEC-PAD system were optimized and standardized for the evaluation of total and soluble AX comparing the results with those of the spectrophotometric methods.

MATERIAL AND METHODS Samples Wheat flour, wheat bran and wholemeals of barley, spelt, emmer and durum wheat were used for the determination of total and soluble AX. AX analysis by phloroglucinol method (Douglas, 1981) Total AX: flour (5.0 mg) is added to 2 mL of water followed by 10 mL of a solution of glacial acetic acid, hydrochloric acid, phloroglucinol in a stoppered tube. The tube is placed in a boiling water bath for 25 minutes and the absorbance of the resulting solution measured at 552 nm and 510 nm.

AX analysis by orcinol-HCl method (Hashimoto et al., 1987) Water soluble AX: 100 mg of flour sample are shaken in water at 30°C for 2 hours and centrifuged. Aliquots of the supernatant are hydrolyzed with 4N HCl at 100°C. The AX content is estimated, after treatment in boiling water bath with FeCl3 and orcinol and reading the absorbance at 670 nm. Total AX: flour (10 mg) is weighed into a glass tube, where 2 mL of 2N HCl are added, and the mixture is hydrolyzed at 100°C for 2.5 hours. After cooling, neutralization is carried out by the addition of 2N sodium carbonate and fermentable sugars are removed by Tecnica Molitoria International - Yearly issue 2009 - 117

flour analysis means of fresh compressed yeast. The mixture is then centrifuged and an aliquot of the supernatant is treated with FeCl3 and orcinol in boiling water bath, then the absorbance is read at 670 nm.

AX analysis by HPAEC-PAD method Water soluble AX: 100 mg of flour sample are shaken in 10 mL of water at 30°C for 2 hours and centrifuged. Aliquots (1 mL) of the supernatant are hydrolyzed with 4N HCl for 2 hours. Total AX: flour (10 mg) is weighed into a glass tube, 2 mL of 2N HCl is added, and the mixture is hydrolyzed at 100°C for 2.5 hours. After cooling, neutralization is carried out by the addition of 2N sodium carbonate.

Fermentable sugars are removed by fermentation: 2 mL of a 25 mg/mL of 0.2M Na phosphate buffer (pH 7) were added in a suspension of fresh compressed yeast (Saccharomyces cerevisiae) and incubated for 15 h at 30°C. The mixture is centrifuged and the obtained supernatant is diluted and injected in the chromatographic system. For the sample injection a Rheodyne injector (Cotati, CA, USA) with a 25 µL loop, was used. The chromatographic separation was carried

out with a Carbopac PA1 (250x2 mm) analytical column. The chromatographic run (22 min) was conducted with a 0.25 mL/min flow rate, using a mobile phase of water and 200 mM sodium hydroxide (90%-10%). The control of the instrument, the data collection and the total quantification were carried out by the chromatographic software Chromeleon (Dionex). An HPAEC-PAD Dionex system (Dionex Corporation, Sunnyvale, CA, USA) composed of a gradient pump (mod GP50) with an on-line degaser and electrochemical detector (model ED40) was used. The flow-through electrochemical cell (Dionex) consisted of a 1 mm diameter gold working electrode, a pH reference electrode, and a titanium body of the cell as the counter electrode. The optimized time-potential waveform used was: 0.1 V at 0-0.40 sec, -2.00 V at 0.410.42 sec, 0.60 V at 0.43 sec, -0.10 V at 0.44-0.50 sec.

Total and soluble AX were quantified on the basis of the arabinose and xylose content in the hydrolyzed sample: ([ara] + [xyl] x D x 0.88), where: D = dilution factor; 0.88 = adjustment for free sugar to anhydrous sugar.

RESULTS AND DISCUSSION Standardization of HPAEC-PAD procedure Increasing concentrations of sugars (arabinose, xylose, glucose, fructose and ga118 - Tecnica Molitoria International - Yearly issue 2009

lactose) were used to check the analytical performances of the method (calibration curve, range of linearity, detection limit, repeatability, reproducibility, precision).

The calibration curves, of each sugar

and matrix (flour, wholemeal, bran, etc.) showed a regression coefficient varying from 0.99 to 1.00.

However, the high concentration of glucose released during the hydrolysis, affects arabinose and xylose quantification. Therefore various procedures to reduce the interference of glucose were tested: i) glucose oxidase for the conversion of glucose into gluconic acid (Houben et al., 1997); ii) fermentation of glucose by Saccharomyces cerevisiae (Hashimoto et al., 1987). The last treatment with Saccharomyces cerevisiae allowed the better analytical performances and was selected for the sample preparation.

Fig. 1 shows a typical HPAEC-PAD chromatogram of arabinose and xylose in

total AX of wheat bran and flour using yeast pre-treatment.

Tab. 1 shows the AX content (total and soluble) in different cereals obtained by the three different analytical procedures. The following considerations can be done: i) the phloroglucinol method gives under-estimated AX values in comparison with the orcinol-HCl and the HPAEC-PAD methods; ii) the orcinol-HCl and the HPAEC-PAD methods provide comparable results for both total and soluble AX; iii) the higher AX values of orcinol-HCl method are directly related to interference of glucose that is quantified with arabinose and xylose; iv) the HPAEC-PAD method allowing the

assessment of the amount of the individual sugars (ara and xyl) and their ratio (A/X) gives the opportunity to highlight the AX structural differences.

A wide variability were found for ara and

xyl content and A/X ratios in different cereals (tab. 2). This variability can influence some dough properties, justifying the different behaviour of flour/meal during processing.

CONCLUSIONS The standardized HPAEC-PAD method is particularly suitable for the quali-quantitative AX determination in cereal flour/meal. In addition, the detection of the compositional sugars arabinose and xylose allows to monitor their substitution in the AX chain.

The HPAEC-PAD method therefore is particularly adequate to evaluate the effect of the different treatments/processes on the modifications of AX structure and the influence of AX structure on the processes.

starch Abstract Starch properties and structure of four samples of “farro della Garfagnana” coming from different farms located in Tuscany were investigated in this study. Results were compared with those obtained on a commercial sample purchased in the market. Raw samples were analyzed for ash, protein, starch, total carbohydrates, amylose, and colour characteristics while starch samples were analyzed for swelling power and solubility. Starch structure was studied by using the Differential Scanning Calorimetry (DSC). Concerning the chemical composition, the commercial sample differed significantly for ash, protein, and starch content probably due the cleaning procedure applied. As fas as the gelatinization process is concerned, this sample behaved similarly to other samples examined.

Key words: emmer, DSC, starch

INTRODUCTION Emmer (Triticum dicoccum Schübler) belongs to the socalled hulled wheats. Known as “farro” in Italy, emmer has been cultivated for many centuries in several region of Central Italy (D’Antuono, 1994; Porfiri et al., 2001). It is likely that many of the beneficial properties of emmer are due to the secondary components of its kernel such as structural polymers (cellulose, hemicellulose) gums and mucillages. In Italy, emmer cultivation is well established and even expanding. Farro is appreciated by consumers because it can substitute wheat flour in bread, pasta, cookies, crackers, cakes, muffins etc. Besides, 122 - Tecnica Molitoria International - Yearly issue 2009

the grain is naturally high in fibre and it contains significantly more protein than wheat. Farro is also higher in B-complex vitamins and both simple and complex carbohydrates (Piergiovanni et al., 1997).

In the Garfagnana area (Tuscany), emmer is certified with the EU mark “Protected Geographical Indications” (IGP in Italian, Indicazione Geografica Protetta). As a consequence, its geographic identity is protected by law and its production is certified by a co-operative body, the Consorzio Produttori Farro della Garfagnana. The increasing demand for

Italian farro has led to competition with non-certified farro, grown in lowland areas and often consisting of different wheat species.

In order to assess whether the cultivation environment and practices are able to determine starch properties and structure of “farro della Garfagnana” and make it distinguishable from others of the same kind, a specific study on starch characteristics was set up. The main goal was to find out possible differences able to characterize this particular production.

MATERIALS AND METHODS Sample Characteristics Farro grains (Triticum dicoccum Schübler) came from four different farms located within a typical italian production area in Tuscany (sample 1-4). They were mechanically dehulled at the production site. One dehulled commercial sample, bought on the market (sample 5), was used as a comparison. All samples were ground using a laboratory Mill (Perten Instruments, Inc., Springfield, IL, Usa) before chemical and thermal analyses.

Starch Extraction Starch was isolated from different samples by alkali extraction of the protein. Grains (100 g) were left under

stirring with 700 mL sodium hydroxide solution (0.1 g/100 mL) at 25°C for 4 h. The supernatant was drained off and replaced with the same volume of alkali solution and the slurry was left to stand overnight at 4°C. The liquid supernatant was eliminated, distilled water was added and the sediment was gently ground in a waring blendor.

After the supernatant was discharged, a new volume of sodium hydroxide was introduced under stirring and the slurry was filtered through a 100-200 mesh cloth. The filtered portion was centrifuged and the solid part, containing starch, was scraped off and recovered; this procedure was repeated several times. Then starch was washed with water till the neutralization of the aqueous solution. The purified starch Tecnica Molitoria International - Yearly issue 2009 - 123

starch was dried in a convection oven at 40°C for 48 h.

Chemical Methods Moisture content was determined by heating samples in an oven at 130°C for 1.5 h; crude proteins (N x 5.70) were determined by the Kjeldahl method and ash was determined by incinerating the sample in a muffle furnace (ICC, 2005).

Colour measurements were taken using a reflectance colorimeter (Chroma Meter, CR 300 Minolta Corporation Ramsey, NJ, Usa) equipped with a xenon arc lamp in the L*, a* and b* system. The colorimeter was calibrated with a white tile and b* and L* values were directly used to measure yellowness and lightness respectively. Measurements were taken on the intact kernels.

Total carbohydrates were determined according to the colorimetric phenol-sulphuric acid method (Dubois et al., 1956).

Total pentosans were determined after a preliminary hydrolysis with mineral acid followed by the colorimetric determination at 580 and 670 nm (Delcour et al., 1989).

Total starch was determined by using the amyloglucosidase/α-amylase assay procedure according to McCleary et al., 1997. Starch was first partially hydrolysed and totally solubilised by means of thermostable α-amylase and, then, starch dextrins were quantitatively hydrolysed to glucose by amyloglucosidase.

Readings were performed at 510 nm.

124 - Tecnica Molitoria International - Yearly issue 2009

The determination of swelling power and solubility was carried out on the purified starch as described by Crosbie (1991). The starch sample was weighed into a polycarbonate centrifuge tube to which distilled water was added.

The sample was placed in a constant temperature water bath at 92.5°C ± 0.5°C for a total time of 30°C. Swelling power was calculated as the weight of sedimented gel divided by the original dry weight of starch less soluble dry matter. The supernatant, which was removed by suction, was evaporated and dried at 105°C for 5 hours. The solubility was calculated as g/100 g on dry basis (d.b.).

The amylose content was determined according to the official procedure AACC (1995).

The damaged starch, determined on the purified starch, was tested according to the AACC (1995).

Thermal Analysis Thermal measurements were carried out using a Perkin Elmer DSC-7 (Perkin Elmer Corp., Massachusetts, USA) differential scanning calorimeter. The flours and purified starches (about 0.002 g starch) were carefully weighed into an aluminium pan and a proper quantity of water was added (starch-water ratio 1:2 w/w). The water amount was calculated considering the moisture of the sample. The suspension was homogenised with a steel needle and the pan was closed,

sealed and left to stand for 10 min at room temperature. After this time, the sample was put in the calorimeter previously stabilised at 30°C. The run was conducted in the temperature range 30°-90°C in a nitrogen stream (flow rate at 15 mL/min-1, heating rate 10°C/ min-1).

Statistical Analysis Data reported in this study are the average of replicate measurements. Differences among samples were statistically evaluated by means of the Student’s t test.

Values followed by the same letter in the same column are not significant (p<0.05).

RESULTS AND DISCUSSION Chemical composition of the five samples examined is illustrated in tab. 1.

Some differences, statistically significant, were observed among samples. As far as ash and protein content, samples 1-4 were different among them and from the sample 5.

The ash content ranged between 1.371.97 g/100 g on dry basis (d.b.) while proteins between 11.2-15.1 g/100 g d.b.

Samples 1-4 were characterised by comparable total carbohydrates which differ significantly from those found in the sample 5. These differences can be due to the deeper cleaning process, to whom the commercial sample was undergone, that

produced the removal of a large portion of the outer bran layers from the kernel. This consideration is also confirmed by the low ash content found in this sample (tab. 1).

Pentosans in grains are genetically determined although they can be affected in some way by environmental conditions during growing and ripening. Pentosans in the samples 1-4 were between 3.10-5.18 g/100 g d.b. which did not differ significantly from those found for the sample 5 (3.91 g/100 g d.b.). Concerning the colorimetric indices, not any significant difference was observed between the samples 1-4 and the commercial sample 5.

bility are reported in tab. 2. Samples 1-4 showed comparable starch content that differed significantly from the sample 5. For this parameter can be made the same consideration already done for carbohydrates.

Swelling power (Sw) and solubility (Sol) tests were performed on starch; for this reason, starch purity was verified through the determination of chemical impurities. The protein contamination was quite negligible and ranged between 0.14 and 0.20 g/100 g d.b. while the ash content was between 0.14 and 0.25 g/100 g d.b. Concerning the damaged starch, values found were lower than 5%. The sample weight used for the swelling test was corrected taking into account the damaged starch content found in each sample. Swelling power and solubility are of great technological importance: in fact, these tests have been used to demonstrate differences between various types of starch such as wheat, potato, sorghum etc. (Doublier, 1987).

Sw ranged between 7.4-13.9 g/g d.b while Sol between 10.5 and 16.3 g/100 126 - Tecnica Molitoria International - Yearly issue 2009

g d.b. Sample 2 showed the lowest Sw value while the sample 3 the highest one.

Sample 2 swelled less than the other samples and this could be due to the high amount of pentosans found in this sample (5.18 g/100 g d.b.). In fact, because of the hydrophilic properties of these molecules, water in the sample becomes less available for the swelling process of starch that, as a consequence, resulted inhibited (Flagella, 2006). The solubility pattern did not follow the swelling power. At different swelling power corresponded comparable solubles leached out from the starch granule (sample 2, 4, 5) due to comparable bond strengths able to immobilize the starch substances within the granule.

Gelatinization properties was studied using the Differential Scanning Calorimetry.

Onset temperature (To), peak temperature (Tp) and enthalpy changes (∆Hent) were measured on flours and corresponding purified starch (tab. 3). To and Tp describe the crystallite perfection (Tester and Morrison, 1990; Shi and Seib, 1992) while the gelatinisation enthalpy (∆Hent) reflects both crystalline order and

level of amylopectin double-helical order (Cooke and Gidley, 1992). To and Tp are highly affected by amylose content and amylopectin chain length distribution and the higher is the proportion of longer chains the higher is the gelatinization temperature (Vandeputte et al., 2003).

Concerning flours, data displayed in tab.

The same conclusions can be drawn for the starch samples. ∆Hent, values of raw materials ranged between 6.05 and 6.77 J/g while values of starches ranged between 10.32-11.41 J/g. Comparing flours and starches, ∆H values were always higher in starches than in flours as already observed by other Authors (Iturriaga et al., 2004). A significant correlation (r2 = 0.784, p<0.05) was found between the swelling power and ∆Hent of flours (fig. 1). The swelling power depends on the water-holding capacity of starch molecules. During the swelling, hydrogen bonds, that stabilize the structure of the double helices in crystallites, are broken and they are replaced by the hydrogen bonds with water. Because the Tecnica Molitoria International - Yearly issue 2009 - 127

starch enthalpy change during the gelatinization process is affected by the cristallinity of starch, this can explain the strong relationship found between ∆Hent and the swelling power (Sasaki and Matsuki, 1998).

Key words: International Food Standard, Version 5, food safety, private label

INTRODUCTION The International Food Standard (IFS), or Standard for auditing the producers of retailer and wholesaler branded food products, has been developed in order to provide a basis for auditing private label producers with uniform formulations and audit procedures, and mutual acceptance of audits. The aim was to guarantee a fair evaluation base that lead to a maximum of transparency.

The Global Food Safety Initiative (GFSI), which issued the IFS, was founded in 2000 with the participation of many international trade enterprises, and with the main purpose of creating an international food safety standard for enterprises that produce private labels for retailers. After few years, the IFS Standard reached its fourth Version, issued in January 2004 by the German Tecnica Molitoria International - Yearly issue 2009 - 129

food safety and French associations “Hauptverband des Deutschen Einzelhandels” (HDE) and “Fédération des entreprises du Commerce et de la Distribution” (FCD).

Finally, Version 4 has been revised and replaced by Version 5, issued on August 1st, 2007, and unique version applicable from January 1st, 2008, with the only exception of Italy and Spain, where it has to be applied from April 1st, 2008 [1].

The fifth version of IFS standard is also called IFS Food (where IFS now means International Featured Standard) because of the need of distinguishing it to another standard that has also been developed, specific for transport, storage, and dis-

tribution: the IFS Logistic. Moreover, they are in development the IFS for Household and Personal Care and IFS for Cash&Carry [2].

In previous papers the Authors have examined a case study of implementation of the IFS Standard, Version 4, in companies of the baked confectionery sector and of the pasta-making sector [3, 4].

The aim of this paper is to examine the main differences between the Versions 4 and 5 of the IFS Food, with practical examples of implementation of the new version in the pasta-making sector, and to analyse the trend of its incidence in the Italian wheat processing industry.

COMPARISON OF VERSIONS 4 AND 5 The IFS defines requirements in content, procedure and evaluation of audits.

In Version 4 they were classified into two levels: “Foundation” (the minimum requirements which the food industry must fulfil to obtain an IFS certificate) and “Higher” (the highest standard for the food industry). Furthermore, each criterion indicated recommendations aimed to the adoption of the best practices.

Four “Knock Out” (K.O.) requirements, regarding HACCP analysis, Management commitment, General traceability, and Corrective actions, were also highlighted in Version 4, to be compulsory fulfilled for the issue of the IFS certificate [5].

IFS Version 4 was composed of four parts, regarding: IFS Protocol (comprising Product categories); IFS Standard 130 - Tecnica Molitoria International - Yearly issue 2009

requirements; Requirements for certification bodies and auditors; IFS Report.

Part 2 was the most important from the point of view of the companies aiming to conform to the Standard. It was specially devoted to describe, in five detailed technical chapters, the requirements to be fulfilled regarding “Quality management systems” (included the requirements concerning the HACCP system, the HACCP team, and HACCP study), “Management responsibilities”, “Resource management” (giving attention to human resources in terms of hygiene and medical screening), “Product realisation” (the most extensive chapter, considering product development, factory environment and pest control, waste disposal, traceability, GMOs, and allergens), and “Measuring,

analysis, improvements” (dealing with all kind of controls during production steps, product analysis and corrective actions, i.e. temperature, time and quantity control, foreign body detection, complaint handling, product recall, control of nonconforming products, internal audit) [5].

The new Version has been compiled by the IFS Working Group taking in account the experience previously made in more than 7,000 audits performed against the Version 4 [2, 6], as well as the changes in jurisprudence occurred during the time of applicability of the same Version. The philosophy behind the review has been that of simplifying everything: to reduce the number of requirements, improve the expositive clarity of the whole Standard for a better comprehension, and simplify the system of scoring. Besides, in the period 2005-2006 also Italian associations of retailers and wholesalers expressed their interest into the IFS Standard, so that its fifth version has been developed with the participation and contribution of ANCD (Associazione Nazionale Cooperative Dettaglianti), Federdistribuzione, and ANCC (Associazione Nazionale Cooperative Consumatori) [7, 8]. Consequently, the IFS Working Group has been widened and finally composed of German, French, and Italian members.

By comparing old and new version of

IFS Food, many changes appear to have been made. It is relevant to observe that the K.O. requirements regarding food safety have increased from 4 to 10. On the other hand, a unique check-list of requirements, with no difference between Foundation and Higher level, has been set up, and no recommendations have been indicated. On the whole, the number of requirements (250 in Version 5) has been reduced by 25% respect to the Version 4, due to the removal of some partial duplications. Finally, a new system of scoring has been set up.

An overview of Version 5 shows that also this Version is organised in four parts: “Audit Protocol” (Part 1); “Requirements of the production process” (Part 2); “Requirements for accreditation bodies, certification bodies, and auditors” (Part 3); “IFS Report, AuditXpress Software and IFS Auditportal” (Part 4). Besides, similarly to the 4th Version, Part 2 contains five technical chapters (much more synthetic and clear than Version 4 also thank to the elimination of the distinction between requirements pertaining to Foundation or Higher level, and Recommendations) dealing with Senior management responsibility; Quality management system; Resource management; Production process; Measurements, analyses, improvements.

NEW REQUIREMENTS OF VERSION 5 Although many substantial differences regard Part 3 of the IFS Food Version 5, in

which accreditation and certification bodies are more involved than the productive Tecnica Molitoria International - Yearly issue 2009 - 131

food safety sites, will be discussed here some new requirements, as well as some of the old ones that have become more detailed in the new version, contained in Part 2, because of their main relevance for processing industries. The comparison is held considering all the requirements listed in Version 4, irrespective of their level.

In Version 5, for example, the requirements regarding the “Senior management review” (1.4.1-1.4.4) are more detailed than in Version 4, specifying in explicit way that the results of the internal audits have to be carefully considered to improve quality and for investment planning. Is remarked that the periodic internal audits shall regard infrastructural issues such as buildings, supplying systems, plants and conveying systems, transport, as well as working conditions (environmental conditions, hygiene, security of operators, room layout, and external interferences such as noise and vibrations, that are treated also in point 4.6.1.1), because of their influence on product’s conformity to retailer concerns. However, also some new requirements regarding the senior management are present in Version 5, such as to assign to specific personnel the responsibility for the external communication (crisis management, authorities and communication with media) (1.1.6), and to nominate an IFS representative (1.2.6).

The need of implementing a full, exhaustive, systematic, and well documented HACCP system based on the principles of Codex Alimentarius was already raised in Version 4 and is confirmed at point 2.1.1.1 (“HACCP System”) of 132 - Tecnica Molitoria International - Yearly issue 2009

Version 5. Moreover, taking in account the variations occurred with the issue of the EC Reg. 852/2004 (and subsequent modifications) regarding HACCP, is specified also that the implemented HACCP system has to fulfil, in any case, all the legal requirements of the country in which the productive site is settled, as well as those of the destination countries. It has to be pointed out that a new requirement is listed in Version 5 at the beginning of the paragraph dealing with HACCP, to specify immediately that the HACCP system shall cover every process from goods in to dispatch, including product packaging (2.1.1.2). This subject will be extensively deepened in a specific chapter regarding packaging (4.5).

Although the HACCP requirements are generally substantially the same than in Version 4, the whole description of the steps of the HACCP study in Version 5 is much more detailed and respondent to the principles of the Codex Alimentarius, that are continuously recalled, thus helping the implementation of the system.

For example, in Version 5 the specific requirement “Description of the product” (2.1.3.1) points out in explicit way that it is needed to collect all information about product composition, about physical/sensory/chemical parameters, regarding treatments, packaging modalities, shelf-life, as well as storage and transport conditions, while in Version 4 the corresponding point (1.2.3.4), belonging to the comprehensive requirement “HACCP Analysis”, asked for a “full description of the product with special regard to the parameters sig-

nificantly related to food safety”. Finally, personnel hygiene requirements have to be applied also to contractors and visitors, and the conformity has to be periodically verified, and this is an additional K.O. requirement (3.2.1.2).

The recently published compendium of doctrine for the IFS Food, Version 5 [9], that has to be applied from August 15th, 2008, gives further linguistic and content clarification of the new Version and helps to implement the standard. For example, it points out that the term “risk” shall be changed to “hazard” throughout the whole Version 5, i.e. in 22 requirements where generally risk was associated to “analysis”, so that shall be intended, more correctly, to perform a “hazard analysis”. The difference between “risk” and “hazard” has been clarified in the past by the Codex Committee [10]: hazard is a biological, chemical or physical agent in, or condition of, food with the potential to cause an adverse health effect; risk is a function of the probability of an adverse health effect and the severity of that effect, consequential to a hazard in a food. The doctrine complies with the decisions of the IFS Working Group, and represents a basis for the next version of the standard.

Requirements regarding “Training” (3.3) are more stressed than in Version 4, indicating that is needed to set up a documented programme for staff training that individuates qualified teachers and specifies subjects, participants, and frequency of sessions. Moreover, at each session has to be recorded date, duration, sub-

ject, list of participants and tutors with the corresponding signatures (3.3.4).

Besides, a new requirement specifies that the responsible for the development and maintenance of HACCP system shall have received adequate training in the application of HACCP principles (3.3.2).

Also the requirements regarding sanitary facilities, equipment for personal hygiene and staff facilities (3.4) are more detailed in Version 5 than in 4, indicating that they have to be equipped with cold and warm tap water, liquid soap, and disposable towels (3.4.6). Besides, if the production involves highly perishable food products, additional requirements for warranting adequate hand hygiene (3.4.7) regard automatic faucets, hand disinfection, approved hygiene equipments, and appropriate signs/pictograms.

Regarding the “Production process”, a greater emphasis on specifications in response to retailer concerns is put than in Version 4. In fact, a new requirement has to be fulfilled, about product recipes, that have to fully comply with customer specifications (4.2.3). Moreover, this is pointed out as a K.O. requirement. Besides, another additional K.O. requirement regards the specifications of all the raw materials, ingredients, additives, packaging materials, that have to accomplish current rules and be up to date, unambiguous, available and in place (4.2.2).

About “Product development” (4.3), an additional requirement indicates that the company shall conduct tests in order to investigate compliance with microbiological criteria throughout the shelf-life (4.3.4).

Tecnica Molitoria International - Yearly issue 2009 - 133

food safety In Version 5 special attention is put towards the “Product packaging”, indicating that (4.5.3) the suitability of all materials to be in direct contact with food shall be certified or evidenced, and this applies for packaging in direct contact with raw materials, semi-processed and finished products. About this point, further clarifications are given in the compendium of doctrine [9] indicating that if no certificates of conformity are available, evidences of suitability shall be provided by means of hazard analysis. Moreover, have to be carried out tests to ensure the absence of any possible hazard such as interaction with or contamination of products by all packaging and packaging equipments, and up-to-date test reports shall be available (4.5.4). The doctrine clarifies that tests shall be carried out for all packaging materials which can have negative impact on food, according to the hazard analysis [9].

The packaging suppliers shall provide information about packaging intended use.

Tests should be based on simulations carried out according to current EU rules (EC Regs. n. 1935/2004, and 2002/72, and EC Dir. 85/572) or be based on the on site packaged food products. Finally, IFS requirement 4.5.5 states that, by means of hazard analysis, the company has to verify the capability of the packaging material for each relevant product (by means of sensory tests, storage tests, physic-chemical analyses). At this regard, the doctrine clarifies that, additionally to requirement 4.5.4, companies should test their packaging on their own products to assess the behaviour in real condition other than in simula134 - Tecnica Molitoria International - Yearly issue 2009

tions. Furthermore, if the company uses a new packaging at any step of the production process, there shall be a re-check of all the concerned IFS requirements [9].

All these are additional requirements with respect to Version 4. Besides, also for product labelling there is an additional requirement, to ensure the conformity of products with their labelling when new labels are issued (4.5.8).

Various additional requirements are in the section 4.6, “Factory environment standards”, such as prescriptions for “Plant layout and process flows” indicating that, where production areas are microbiologically sensitive (clean room), a positive pressure system shall be installed and micro-organism measure has to be performed periodically (4.6.3.3).

Regarding “Housekeeping and hygiene” (4.7) Version 5 stresses, better than Version 4, that cleaning programmes have to be implemented based on a hazard analysis, specifying responsibilities, products to be used and their usage instructions, areas to be cleaned, objectives, frequency, and registrations. Besides (4.7.2), cleaning has to be made only by qualified personnel.

An additional K.O. requirement is related to the presence of foreign bodies, metal, broken glass and wood (4.9.1), so that the possible sources of hazard shall be identified, prevention measures have to be adopted, and non-conforming products have to be segregated. Finally, other additional K.O. requirements are related to internal audits (5.1.1), to the need of implementing an effective procedure for product recall and withdraw (5.9.2).

PRACTICAL EXAMPLES IN THE PASTA-MAKING INDUSTRY To update the conformity of an organisation from the Version 4 to the 5th of the IFS Food, it is necessary to accurately analyse all the new requirements in order to evaluate which modifications are needed. Every aspect of the productive site has to be considered, from HACCP system to the quality management system, included corporate structure, personnel, plants and equipments, productive processes, raw material and product specifications, packaging, factory environment (exteriors, plant layout, walls, floors, windows, lighting, air conditioning), measuring and monitoring devices, and documentation.

To evaluate a practical example of implementation, referred to a pasta-making company, two aspects can be considered, which requirements are more detailed in the Version 5 than in the 4th: personnel training and packaging.

About training, Version 4, at point 3.2.4.4 (higher level), required that the organisation set up training sessions, that shall be documented. Besides, point 3.2.4.2 specifies also that training shall be reviewed on a regular basis. As already pointed out in the previous paragraph, the Version 5 is more detailed at this regard, specifying that qualified tutors shall be individuated and a complete training programme shall be set up, indicating subjects, tutors, participants, and frequency of sessions (3.3.1). It is also specified that at each session has to be recorded date, duration, subject, list

of participants and tutors with the corresponding signatures (3.3.4). Besides, a new requirement specifies that the responsible for the development and maintenance of HACCP system shall have received adequate training in the application of HACCP principles (3.3.2).

In tab. 1 is reported an example of training programme of a pasta-making factory. According to the requirements of IFS Food Version 5 (point 3.3.3), it also includes specific training for new personnel, that shall be trained before starting working. Besides, at each training session, the corresponding data shall be recorded in a form, for example the â&#x20AC;&#x153;Training reportâ&#x20AC;? shown in tab. 2. It could also contain additional data such as the judgement of the single participants, issued after a final evaluation, to be subsequently inserted into the personal file of each employee. The training programme will be generally centred on topics of main interest from the technical or legislative point of view, as well as about the causes of the possible nonconformities (3.3.5).

The non-conformities in a pasta-making factory can be numerous, related to raw materials or process, for example pasta defects due to insufficient stabilisation, stuck pasta pieces due to surface condense, broken pasta due to damages during packaging. Each non-conformity has to be examined to individuate its causes.

the study of the non-conformities, in order to prevent them in the future.

The importance of training is essential for any organisation, as remarked also by ISO 9001:2000, and in a food processing industry it has a basic influence on food safety. In fact, to improve food safety performance, it is important changing working behaviour according to procedures. The main aim should be that of achieving more than just a foodsafety program, i.e. an acquired and well assimilated “food safety culture” [11]. The continuative adoption of IFS or other standards during time should act in this direction, rendering more and more familiar the basic concepts of food safety.

In particular, all employees shall be informed about the CCPs and the monitoring procedures related to them. For example, the production process of eggpasta shows a CCP about the acceptance of the incoming pasteurised liquid egg, when has to be checked both the presence of the documentation and the temperature, that shall not exceed 4°C. After that, this raw material has to be immediately stored in a refrigerated cell equipped with thermal probes to continuously monitor the internal temperature, and with systems of acoustic alert for any deviation. Also the IFS Version 5, at point 4.11.3, remarks the importance about the storage conditions of raw materials, that shall correspond to product requirements such as refrigeration. Then, it is needed to verify, by an immersion thermal probe, that the

temperature does not exceed 4°C during the input of liquid egg in the processing line. The employees has to know that any non-conforming behaviour can provoke a microbiological contamination by Staphilococcus aureus [12, 13].

About the other requirement stressed in detail in IFS Version 5, Product packaging (4.5), it is essential to purchase packaging from qualified suppliers. There shall be a procedure for approval and monitoring of suppliers (4.4.3-4.4.4) based on criteria of reliability, as well as on audits, and results of certificates of analysis. The responsible for purchasing shall store the conformity certificates of all the materials used (4.5.3).

In conformance with points 4.5.4 and 4.5.5, and according to the compendium of doctrine [9], have to be made tests (physic-chemical analyses and sensory tests) examining pasta samples for example after 6 months from the production and in different storage conditions, in terms of light exposure and temperature (storage tests), to exclude any release from packaging. Sampling shall take in account any variation in packaging material and/or supplier. These analyses, relevant for food safety, shall be carried out by an accredited laboratory (ISO/IEC 17025:2005), otherwise, if made by a factory internal laboratory, the results have to be validated on a regular basis by an accredited laboratory.

About product labelling (4.5.8), all the compulsory and facultative indications, from “Best before” to pasta cooking time indications, as well as the linguistic Tecnica Molitoria International - Yearly issue 2009 - 137

food safety correctness of the indications, have to be checked when new labels are issued, and personnel have to verify the conformity of products with their labelling during all the production process (4.5.9).

The reels of packaging material shall be stored in an adequate place (4.5.7) and shall be singly enveloped by cellophane to protect by dust or other contaminations.

SCORING AND AUDIT REPORT The evaluation of the requirements during the audit against the IFS Food Version 5 lead to calculate a total score on which the issue of the certificate depends.

Different audits can be performed: initial audit, that is the first audit performed by a certification body; follow up audit, focussed on checking the implementation of corrective actions, and scheduled when the initial audit does not allow a certificate to be issued; surveillance audit, that is a complete audit performed at a frequency that depends on the level achieved at the last audit.

Each criterion has to be evaluated, to verify if it is accomplished in full way, or partly, or not at all. Depending on this, a different score will be attributed. At the end all the scores will be summed.

It can be observed (tab. 3) that a K.O. requirement can be scored A, B, or D, not C. Each time a B, C and D score is attributed to a normal requirement, or a B score is attributed to a K.O. point, a deviation has been detected and the auditor has to provide an explanation in the audit report [14].

In addition to the score, the auditor can assign a non-conformance. IFS Food admits two kinds of non-conformances: major and K.O. A major non-conformance occurs when there is a substantial failure in fulfilling food safety and legal requirements which can lead to a serious health hazard. Major non-conformances can be detected on each requirement that is not classified as K.O., and will lead to subtract 15% of possible total amount.

Subtract 50% from the possible total amount (D=K.O.)

Otherwise, they will be classified as K.O. non-conformances (score D), and will lead to subtract 50% of possible total amount, preventing the issue of the IFS certificate. When a major non-conformance is detected, or a K.O. point is classed D, a corrective plan is required [14].

A K.O. requirement can not be scored as not applicable (N/A), with the only exception of the requirement about monitoring of CCP (2.1.3.8). It might be not applicable according to the company and the products processed (if the company has not identified any CCP), and a detailed justification shall be given in the audit report [9].

After the auditing process, if the total score is ≥ 75 and < 95%, will be approved the issue of the IFS certificate at the Foundation level, while if the score is ≥ 95%, the certificate will be issued

at the Higher level. It is remarkable to observe that the Version 4 of the IFS required lower percentages for both the levels (70% at Foundation and 90% at Higher level), so that there should have been an improving in the performances of the audited companies to maintain the certificate.

The presence of a single K.O. non-conformance does not enable the approval of the certificate, as well as the presence of more than one major non-conformance. When one major non-conformance is detected and the total score is ≥ 75%, the certificate is not approved until the auditor verifies the implementation of the corrective plan [14].

When the certificate is issued, IFS Food Version 5 foresees an audit frequency of 12 months for all sites, irrespective of level achieved.

FOOD DEFENCE CHECK-LIST The compendium of doctrine about IFS Food Version 5 has added another chapter to the standard (Chapter 6) dealing with optional requirements about “Food defence”, for those food industries that want to evidence that they consider this topic. The food defence programme is a major issue in USA and a regulatory requirement about it has to be applied by the food industry [15, 16].

The food defence is achieved by specific security measures aimed to protect production sites, food related materials and finished goods from intentional

harm including crime and terrorism. For example requirement 6.2.1 foresees that if is identified an area that is critical for security, intrusion of unauthorised persons has to be prevented by measures such as self-closing doors, access only with chip card or permanent staff on site. Besides, at point 6.3.1 is asked to register visitors and external service providers at the time of access, while at 6.3.2 is remarked the importance that all employees are trained in food defence.

be shown separately in the IFS audit and is independent from the global IFS Food audit score.

RESULTS AND TRENDS IN THE ITALIAN WHEAT-CHAIN Italy, with 17 auditing organisations accredited to certify the conformity to IFS in 2008 [2], ranks fourth in Europe, after Germany, Spain, and France, for number of approved IFS certification bodies (tab. 2). Their number has raised from 7 at the end of 2006 [17]. The IFS standard, born in Europe, is diffusing also outside Europe, with 64 certification bodies operating in 23 different non-European Countries at the

end of 2008 (tab. 4) [18]. The growth is evident, considering that the number of certification bodies was 29 at the end of 2004. Besides, from a total number of 1677 IFS audits at the end of 2004, it has been exceeded the number of 7,300 at the end of 2007 [1]. The majority of them (more than 6,800) has been held in Europe, the remnant in the other continents [1].

In Italy, SINCERT data indicate that ISO

9001:2000 is generally the most diffused standard, but in the agri-food sector the â&#x20AC;&#x153;Business to businessâ&#x20AC;? (B2B) certifications (IFS, BRC and GlobalGap) are well represented and are progressively increasing [19]. DNV released 169 IFS certificates in 2007, with an increase of 55% with respect to 2006. Also Certiquality observed an increase, as well as CSQA (+17%) [20]. From about 400 companies certified in 2005 [7], classifying Italy at the second place after Germany for number of IFS certificates, it has been progressively reached the total number of 860 certificates at the end of 2007 [1].

The number of companies certified in Italy against the IFS Food Version 5 has already reached that of about 250 at November 2008, i.e. in less than one year of application of the new version.

As far as the wheat chain is regarded, perusal of the list of certifications released by CSQA [21], shows that the pasta-making factories represent about 15% of the total of certified companies, while in October 2007 they were about 10% [4]. Besides, 42% of them produce dry pasta, 29% produce fresh pasta, and the remnant 29% produce dry and fresh pasta, also stabilised and/or frozen.

Moreover, about 5% of the total of certified companies are from the sector of baked products, and 1% are involved in milling. In the bakery sector, the 55% of the certified productive sites are devoted to bread and bread substitutes production, while 45% belong to baked confectionery.

The available statistic data indicate that in 2004 the number of pasta-making factories in Italy was 146, those of the confectionery sector were 220 [22], and in the industrial bakery sector there were 270 factories [23] (apart from a large number of artisanal small bakeries, for example 1381 in Milan, and 745 in Rome, as reported in the data bank of the Italian bakers) [24]. Finally, 178 durum wheat milling factories resulted to be present in Italy in 2004, and 338 soft wheat mills [22], decreased to 288 in 2007 [25].

Besides, in 2006 the turnover has been of 10,146 millions of euro for baked confectionery, 3,519 millions of euro in the sector of pasta, and 2,407 millions of euro for milling [26], with an increase respect to 2004, when the same sectors showed figures of 10,023, 3,410, and 2,205 millions of euro, respectively [27]. So, as a mean, the sector of baked confectionery represented 9.3% of the whole turnover of the food industry, while pasta 3.2%, and milling 2.2% [26, 27].

It is possible to observe that the above reported data do not reflect the proportions among about IFS certified companies involved in the various sectors of the wheat-chain, indicating that the number of certificates follows other criteria, such as the ability of a specific category of product of being inserted into the private label display. In fact, among the different commercial categories, pasta is the most represented private label product after olive oil, immediately followed by biscuits [28].

Tecnica Molitoria International - Yearly issue 2009 - 141

food safety The incidence of IFS certification is especially important in this period, when the preference of Italian consumers for private label products, due to economic reasons related to the raise of prices, is increasing. They usually are medium price products, with a good quality/ price ratio. Dry pasta, according to an Iri Infoscan study, performs sale figures of about 784 millions of Euro in the largescale retail, and this sector has faced an

increase of exchanges for private label products from 9.4% in August 2007 to 11.1% in February 2008 [29], while on the whole the domestic pasta market in 2007 has encountered a sell decrease of 1.6% in volume (as the sum of dry and fresh pasta) [30]. Moreover, a study carried out by SINCERT indicated that 74% of a panel of consumers perceive the private label as able to warrant product quality [31].

CONCLUSIONS Nowadays the complexity of the food system of developed countries is increasingly removing consumers from most aspects of food production, and retail food establishments have become the main place where consumers get their food. Besides, retailer and wholesaler branded food products are becoming more and more diffused. In this framework, raises the importance of a standard such as the IFS Food that, providing an efficient and transparent tool to audit private label producers, concurs to improve food safety.

New requirements have been added in

the Version 5 of this standard, above all regarding food packaging, in line with EC regulations, and specifications of products and raw materials in response to retailer concerns, further enhancing the food safety level.

The continuative adoption of IFS Food or other standards during time could consolidate the culture of the food safety by the producers, but, in parallel, has to be pointed out the need, by consumers, of increasing the awareness of the food production system and of regaining a tighter connection with the producers.

oat Abstract As the request of oats for human consumption continues to increase, the demand for raw materials with particular nutritional characteristics requires specific breeding programmes, aimed at the release of improved oat cultivars that could meet the needs of food industries. In this paper, a group of husked and naked oat cultivars and breeding lines were characterised for their β-glucan content in order to select genotypes with a high nutritional value and a good potential for industrial transformation. A wide range of variation for this trait was observed in both husked (2.744.86 g kg-1) and naked genotypes (2.90-5.80 g kg-1); moreover, some selected naked oat breeding lines were identified with a high β-glucan content and seed weight, which could be exploited as raw materials for the development of high nutritional value foods.

Key words: naked oats, β-glucan, functional food

INTRODUCTION Due to the increasing interest in the role of nutrition in health maintenance and disease prevention, many researches have been conducted to clarify the relation between diet and health, and to identify the association between active food components and chronic disease risk reduction. In the last decade, in particular, the physiological properties of functional dietary fibre components have been largely examined. Insofar, epidemiological studies allowed to evidence that a group of indigestible components of plant foods, of which dietary fibre is composed, have different beneficial physiological effects in humans (ADA, 2002). β-glucans, homopolysaccharides of branched glucose residues, are constituents of endospermic cell wall of oats and barley; they have been largely descripted as dietary and functional fibres.

The different physiological effects on health of oat-based foods, rich sources of soluble fibre β-glucans, however,

144 - Tecnica Molitoria International - Yearly issue 2009

are associated with their ability to form a viscous mass in the digestive system (Ajithkumar et al., 2005). As a result, the increased lumen viscosity attributed to the high oat soluble fibre intake may determine both the glucose metabolism improvement and the cholesterol lowering (Wood, 1994; Wood et al., 1989; Wood et al., 2002; Lazaridou and Biliaderis, 2007).

As the request of oats for human consumption continues to increase, the demand for raw materials with particular nutritional characteristics requires specific breeding programmes aimed at the release of improved oat cultivars that could meet the needs of food industries. In particular, high β-glucan concentrations are desirable for the development of functional foods (CervantesMartinez et al., 2001; Chernyshova et al., 2007).

Following these indications, in the past few years our research activity on oats was addressed to the development of new naked oat varieties for food industry with the aim to increase the use of oats for human nutrition (Redaelli et al., 2005, 2006a and b; Sgrulletta et al., 2007, 2008). The results gave useful indications relative to the research objectives and evidenced that genotypic variability for grain β-glucan concentration was an important factor to be considered.

This paper focuses on the determination of β-glucan content in a group of oat cultivars and breeding lines and in their progenies. The results of these analyses could help identify the most suitable genotypes to be exploited in a specific breeding program to select new raw materials with high nutritional value for functional food industry.

MATERIALS AND METHODS Plant material Husked and naked oat cultivars and breeding lines were used in this study.

Among the husked materials, most cultivars were bred in Italy, including lines BD118 and BD134; cultivars Hamel and Aveny were from France and Sweden, respectively. Among the naked genotypes, BD114, BD124 and Liria (ex BD123) were selected from CRA breeding programs; Nave, Irina (ex BD131) and Luna (ex BD137) are Italian culti-

vars, the former registered in 1983, the others in 2008; Hja72095N and Rhea x Padarn 542 are breeding lines from Finland and France, respectively; Bullion, Expression, Grafton, Hendon, Racoon and 13914Cn (spring type) were obtained from United Kingdom. These genotypes were multiplied in head-rows in 2006-07 in Bergamo, together with the progenies of different crosses (F3, F4 or F5). Panicles were harvested by hand and threshed and grain samples were used for β-glucan determination.

oat Analytical methods For chemical analyses, 50 g of grains (husked or naked) were ground in a Udy Mill Cyclotec (FossItalia - PD, Italy) with a 0.5 mm sieve. Moisture was determined with a thermo-balance (Sartorius MA

40 - Gottingen, Germany) at 120°C. Total β-glucan content was determined using the enzymatic method of Mc Cleary and Codd (1991).

All the analyses were carried out in duplicate, and the data were reported on a dry matter basis.

RESULTS Husked oat genotypes Eleven husked genotypes were analysed for β-glucan content (tab. 1). The values ranged from 2.74 g kg-1 (Argentina) to 4.86 g kg-1 (Fulvia). Hamel, Donata and Aveny showed β-glucan contents higher than 4.00 g kg-1. The significance of the differences observed was evaluated statistically by Duncan’s test.

Naked oat genotypes Fourteen naked oat genotypes were also screened for β-glucan content (tab.

2). Values were very different, ranging from 2.90 g kg-1 (Rhea x Padarn 542) to 5.80 g kg-1 (Expression). A high content was found also in Liria (4.98 g kg-1), 13914Cn (4.93 g kg-1) and Racoon (4.82 g kg-1). The significance of the differences observed was evaluated statistically

by Duncan’s test.

In recent years some of these genotypes were used as parentals in naked oat breeding programs. Selected progenies from a few crosses were analysed in order to describe the distribution of 146 - Tecnica Molitoria International - Yearly issue 2009

β-glucan content in F3, F4 or F5 generations. The results are summarised in tab. 3: for each cross the mean value, LSD 0.05, the number of samples analysed and the range of variation are reported.

The mean value for β-glucan content was highest in the progeny of the cross BD124 x Liria (4.22 g kg-1) and lowest in the progeny of the cross Irina x (Rhea x Padarn 542) (2.85 g kg-1). The range of variation for this trait was quite large, especially in crosses Bullion x BD124 and BD124 x Hja72095N. Some progenies resulted to be quite interesting, as

they were characterised by a β-glucan content higher than 5.00 g kg-1.

Seed weight was also evaluated in these progenies: cross Irina x (Rhea x Padarn 542) had the smallest grains (mean value = 20.3 g), whereas cross BD124 x (Rhea x Padarn 542) had the highest seed weight (mean value = 28.1 g). On average, the mean value of seed weight for these genotypes was 24.9 g and the range of variation was comprised between 19.1 and 30.6 g. The correlation between β-glucan content and seed weight in these samples (r = 0.21; n = 44) was found to be not significant.

DISCUSSION Oats are recognized as a healthy food recommended for human consumption and the improvement of oat quality expressed as nutritional and functional characteristics favours higher fibre component concentrations, in particular the soluble β-glucan. Numerous studies have been focused in the past on the existing variability of oat β-glucan content and the interaction between genetic and environmental factors (Welch and

Lloyd, 1989; Lim et al., 1992; Brunner and Freed, 1994; Peterson et al., 1995; Doehlert et al., 2001; Sgrulletta et al., 2002; Peterson et al., 2005). The data obtained were discordant about the influence of the growing environment on the accumulation of the qualitative traits in the oat grain. However, as in some cases the year of cultivation was found to affect the β-glucan accumulation, all the genotypes analysed in the present Tecnica Molitoria International - Yearly issue 2009 - 147

oat study were grown in the same field conditions and in the same year, so that the observed differences could be ascribed to a genetic factor only.

A large range of variability was observed for β-glucan content, both for husked and naked genotypes. The inheritance of this trait was also explored in the progeny of different crosses: we identified some selected lines with a β-glucan content greater than the genotypes used as parentals; these lines could be successfully developed to obtain new cultivars with an improved nutritional value. In previous studies it was found that the genetic control of this trait was not simple and the presence of two or more genes with additive effects was the most probable hypothesis (Holthaus et al., 1996; Kibite and Edney, 1998; Cervantes-Martinez et al., 2001).

Correlations among β-glucan and other agronomic or qualitative traits were also calculated in some papers, and resulted to have a different level of significance in different crosses. In the present study the correlation between β-glucan and seed weight was not significant; how-

ever, it was interesting to note that all the naked progenies with a high seed weight (>26 g) derived from the crosses in which line BD124 was the female parent.

In these past few years the general interest in health addressed consumers towards the choice of more healthy and nutritious foods. At present, “good nutrition” means the choice of food products particularly high in starch and dietary fibre components; in the new guidelines, in fact, whole grain is considered an important part of nutrition as rich source of fibre components. Oats and oat products are a good source of soluble fibre, which has proven effective in health safeguarding. The results here discussed allowed to identify the suitable raw material for producing oat-based food with increased functional properties.

whole grains Abstract Recent epidemiological studies have shown that the consumption of whole grains and wholemeal cereal products appears to reduce the risk of diseases such as cardiovascular diseases, cancer, diabetes, etc. However, the scientific bases of the above mentioned positive effects are currently under investigation. In this work, we tried to investigate and describe a profile of the most important bioactive substances in cereals such as phenolic acids, carotenoids and lignans and to evaluate the total antioxidant capacity of whole grains usually cultivated and consumed in Italy, by means of two different assays, TEAC (Trolox Equivalent Antioxidant Capacity) and FRAP (Ferric Reducing-Antioxidant Power).

As regards the bioactive substances, grain samples of soft and durum wheat, barley, oat, emmer, spelt, triticale, rye, rice and maize were analyzed

by HPLC methods. For each species, two or more representative cvs were analyzed to have an idea about the in species variation. The results showed a large variation in the kind and amount of bioactive substances present, both at the specific and at the varietal level. Our data on phytochemicals in grains could provide a scientific basis for cereals breeding but also for the development of functional whole grain cereal foods.

INTRODUCTION By the late 20th century, the importance of whole grains had been rediscovered, first by the natural foods movements and later by the scientific community. In these last years, there has been an evaluation of the role of cereals in the diet and their possible implication in the prevention of health diseases. This role has been acknowledged by both food manufacturers and consumers (Lorenz and Lee, 1977; Slavin et al., 1997; Slavin, 2004).

In particular, from several investigations it appears that wholegrain cereal foods could reduce the risk of diseases such as coronary heart disease, stroke, cancer and diabetes (Salmeron et al., 1997 a,b; Chatenoud et al., 1998; Koh-Banerjee and Rimm, 2003).

One of the major cause of death or disability in the United States is represented by heart diseases. Several studies sustain the linkage between consumption of whole grain foods and CHD (coronary heart disease) prevention.

Truswell (2002) have shown consistent protective effect

150 - Tecnica Molitoria International - Yearly issue 2009

of whole grain cereals in coronary heart diseases. Liu et al. (1999) have demonstrated as an increased intake of wholegrain cereals appears to be negatively associated with heart attacks and other heart problems in 75,000 nurses over 6 years. Cereals provide calories and important nutrients to the diet. In fact, several components in cereals have a recognized potential for reducing risk factors for CHD: linoleic acid, fibre, vitamin E, selenium and folate.

The high fiber content of unrefined cereal products is believed to aid in the prevention of certain diseases. In the literature a lot of investigations are reported regarding the role of a high-fiber diet on the physical health status: positive effects in the gastrointestinal tract support weight reduction and are involved in carbohydrate and fat metabolism (Kaline et al., 2007). Priebe et al. (2008) and Venn and Mann (2004) demonstrated the properties of whole grain cereal products in the prevention of type 2 diabetes mellitus due to the presence of insoluble dietary fibers.

Whole grains appear to be a rich source of a wide range of phytochemicals with anti-carcinogenic properties. A relationship has been suggested between whole grain consumption and cancer (Slavin et al., 1997; Tavani et al., 1997). In a review of 54 case-control studies spanning 20 types of cancer and colon polyps, people with high intakes of whole grain had 20 to 50% less risk of most malignancies (Jacobs et al. 1998 a,b). The same Authors have reported that high intake of

whole grain foods consistently reduced risk of cancers of the oral cavity and pharynx, esophagus, stomach, colon, rectum, liver, gallbladder, pancreas, larynx, breast, endometrium, ovary, prostate, bladder, kidney, lymphatic system, and multiple myelomas.

The beneficial properties of whole grains are attributed in part to their unique phytochemical composition: vitamins and minerals, unsaturated fatty acids, tocotrienols, tocopherols, insoluble and soluble fiber, phytosterols, stanols, sphingolipids, phytates, lignans, and antioxidants like phenolic acids (Adom and Liu, 2002, Adam et. al., 2003, 2005; Gabrovskรก et al., 2002). Within the whole grains phytochemicals, lignans, found in particular in the outer layers of grains, could mediate hormone-related diseases. Several investigation have shown that food lignans are converted to mammalian lignans when consumed by humans; mammalian lignans have a similar structure to the human hormone oestrogen and so may have oestrogenic/anti-oestrogenic effects (Adlercreutz et al., 1995).

It is likely that whole grain components work together to achieve a synergistic effect.

Processing, when it involves the removal of the outer layers of grain, generally reduces the content of nutrients and bioprotective substances (Zielinski et al., 2001). Therefore, whole grains seem to be necessary in a healthy diet.

On the other hand, new research has emerged about negative effects connected to a diet too much rich in grains.

Tecnica Molitoria International - Yearly issue 2009 - 151

whole grains The Seven Countries Study, which has followed the eating patterns of over 12,000 men for almost 30 years, showed that the risk of stomach cancer increases with high intakes of grain foods (Jansen et al., 1999).

In this work, we tried to investigate and

quantify a phytochemical profile for some important molecules (phenolic acids, carotenoids and lignans) and to evaluate the total antioxidant capacity of cereal grains usually cultivated and consumed in Italy, with the aim of contributing to the knowledge on their potential effects in human health.

Ika Labortechnik, Germany) and the wholemeal flours were sieved to obtain a granulometry of 0.5 mm. Oat, barley, rye, rice, emmer and spelt had been commercially dehulled before milling.

Only for the analyses of lignans, flours were defatted with hexane and diethyl ether for 8 h in a Soxhlet apparatus.

Chemicals and standards The organic solvents used for the separation of carotenoids, lignans and phenolic acids were of HPLC grade and purchased from Carlo Erba (Milan, Italy).

Carotenoids and phenolic acids standards were purchased from Sigma-Aldrich (Milan, Italy). Lignans standards were purchased from Chemical Research (Rome, Italy).

Total antioxidant activity determinations Each sample was submitted to the extraction method of Halvorsen et al.

(2002). The antioxidant activity (TAC) was evaluated using two different assays, FRAP (Ferric reducing-antioxidant power) and TEAC (Trolox Equivalent antioxidant capacity). The FRAP determination was performed according to Benzie and Strain (1996), using a Tecan Sunrise plate reader spectrophotometer (Männedorf, Switzerland). The method is based on the reduction of Fe3+-TPTZ (2,4,6-tripyridyl-s-triazine) complex to ferrous at low pH. The TEAC determination was performed according to Miller et al. (1993) and Re et al. (1999). This assay measures the ability of antioxidants to quench radical cations.

EXTRACTION AND QUANTIFICATION OF CAROTENOIDS Carotenoids were determined by the method of Sharpless et al. (1999) used by the National Institute of Standards and Technology (NIST). Briefly, approximately 1 g of sample was combined with 3 mL THF (tetrahydrofuran) and 2.7 mL methanol. The mixture was saponified for 30 min in a 40°C water bath after adding 0.3 mL of a 40% (w/v) methanolic KOH solution, and then ca 0.15 g ascorbic acid was added to neutralize the KOH. The analytes were extracted with three 15 mL por-

tions of hexane-diethyl ether (50+50).

The organic phase was combined and evaporated under a stream of nitrogen and the residue redissolved in 10 mL of n-hexane. For the analysis, 1 mL of the sample was rievaporated and reconstituted in 1 mL of mobile phase (50% methanol, 45% acetonitrile and 5% tetrahydrofuran). 50 µL of reconstituted extract were injected in a Waters Nova Pack C18 column (3.9x150 mm, 4 µm) (Waters, Milford, Massachusetts, USA) at a flow rate of 1 mL min-1. The extracts Tecnica Molitoria International - Yearly issue 2009 - 153

whole grains were analyzed by a Perkin-ElmerISS 200 series HPLC system (Perkin-Elmer, Norwalk, CO, USA). The eluents were Methanol/Acetonitrile/Tetrahydrofuran (50:45:5). The peaks were detected

with a variable spectrophotometric detector (Perkin-Elmer LC-95) connected to a personal computer Pe Nelson mod 1020 (Perkin-Elmer). The detection wavelength was 450 nm.

EXTRACTION AND QUANTIFICATION OF PHENOLIC ACIDS Each sample was extracted in duplicate by the procedure of Hatcher and Kruger (1997) to isolate phenolic acids. The soluble fraction was initially extracted with acetone/water and methanol/ water. The free soluble fraction was then extracted with ethyl ether/ethyl acetate. The soluble esterified fraction, left after extraction of the free one, underwent an alkaline hydrolysis and acidification. The insoluble bound fraction was determined after separation of the soluble fraction, alcaline hydrolysis and passage through Supelclean

LC18 SPE Tubes (6 mL) (Supelco Inc., Bellefonte, Pa, USA). Each extract was analysed with a Perkin Elmer, Series 400 (USA) Liquid Chromatograph using a reverse phase Supelco LC-18 analytical column (15 cm x 4.6 mm) at room temperature. Detection was done at 260 nm with a Perkin Elmer LC 95 UV Spectrophotometer Detector.

Calibration standards consisting of vanillic, caffeic, syringic, p-coumaric, ferulic and sinapic acids (Sigma Chemical Co, St. Louis, Mo, USA) were run with each series of samples.

EXTRACTION AND QUANTIFICATION OF LIGNANS Samples were extracted taking into account the methods of Obermeyer et al. (1995) and Milder et al. (2004). 12.0 mL of alkaline hydrolysis reagent (0.3 M NaOH in 70% MeOH) were added to 0.5 g of samples and, after stirring, were incubated for 1 h at 60°C. The samples were cooled down to room temperature and neutralized with 100% acetic acid (380 µL). The hydrolysate was centrifuged (3,500 g, 10 min). An aliquot (2 154 - Tecnica Molitoria International - Yearly issue 2009

mL) of supernatant was transferred into a test-tube. The supernatant was evaporated until only water was left (600 µL).

Water (1.4 mL) was added together with 2 mL of sodium acetate buffer (0.05 M, pH 5.0) and then 400 µL of Helix Pomatia β glucuronidase/sulphatase were added (β-glucuronidasi/sulphatase S9626-10KU Type H-1, 0,7 G solid, 14,200 units/G solid, Sigma in 10 mL of acetate buffer). The samples were incubated in a shaker wa-

ter bath at 37°C for 24 h. Samples were evaporated to dryness and dissolved in 1 mL mobile phase. Quantitative analyses were performed on 50 µL extract using an ESA-HPLC system (ESA, Chelmsford, Ma, USA). The HPLC system used consisted of an ESA Model 540 autoinjector, an ESA Model 580 solvent delivery module with two pumps, an ESA 5600 eightchannels coulometric electrode array detector and the ESA coularray operating software which controlled all the equipment and carried out data processing.

A Supelcosil LC-18 column (25 cm x 4.6 mm, 5 µm) with a Perisorb Supelguard LC-18 (Supelco, Milan, Italy) was used.

Chromatography was performed at 30°C, at a flow rate of 0.8 mL/min using the following solvent system: solvent A, ammonium acetate 50 mM adjusted to pH 4 with glacial acetic acid; solvent B, methanol. The linear gradient used consisted of

28% solvent B, increasing to 30% over 4 min and to 40% over 41 min, held for 10 min. After that, returning to 28% solvent B over 3 min and monitoring this condition for 5 min.

The working potentials of the eight cells were set up at 60, 120, 200, 340, 480, 620, 760 and 900 mV. Sample peaks were analyzed by matching target peaks with standard peaks on the basis of their retention time and on accuracy ratio between adjacent channels. Isolariciresinol, lariciresinol, secoisolariciresinol, pinoresinol, matairesinol were detected and quantified. In particular isolariciresinol and matairesinol were not identifiable for the presence of interfering compounds at the same retention time. The sum of identifiable lignans was indicated as total lignans. Values, expressed on dry matter, are in general the average of 3 determinations unless otherwise stated.

RESULTS AND DISCUSSION The most reliable explanation for the health protective effects of foods, with particular attention to fruits and vegetables, derives from the observation that vegetables/beverages are rich in antioxidant molecules such as ascorbic acid, α-tocopherol, β-carotene, polyphenols, flavonoids and hydroxycinnamic acids.

These constituents are known to have antioxidant, anticarcinogenic, antimutagenic and antineoplastic activities.

There is also considerable interest in grains as a source of biologically active

compounds. Infact, whole grains contain numerous molecules that possess antioxidant activity, which are not present in highly refined products. In this work we focused our attention on the content of some of the most important bioactive molecules (phenolic acids, carotenoids and lignans) in whole grains, usually cultivated and consumed in Italy, and on the antioxidant activities of their wholemeal flours. For some species, more than two different genotypes (cultivars) were studied.

Tecnica Molitoria International - Yearly issue 2009 - 155

whole grains Considering that we were analyzing different species, for the evaluation of the Total Antioxidant Power we decided to use a simple and generic extraction method. However, we have to point out that, following this extraction method, we assessed the contribution of the free bioactive molecules only and not of the conjugated forms. Consequently, we underestimated the antioxidant power in our samples, which is due to both free and conjugated forms.

Pérez-Jiménez and Saura-Calixto (2005) conducted an assessment of the antioxidant capacity of cereals using both chemical and in vitro digestive enzymatic extraction of antioxidants and concluded that the amount of antioxidants released by enzymatic treatments may be higher than those obtained using aqueous-organic extraction.

Adom et al. (2003) investigated the antioxidant profile of grains: corn had the highest total antioxidant activity (181.42±0.86 µmol of vitamin C equiv/g of grain), followed by wheat (76.70±1.38 µmol of vitamin C equiv/g of grain), oats (74.67±1.49 µmol of vitamin C equiv/g of grain), and rice (55.77±1.62 µmol of vitamin C equiv/g of grain).

In tab. 1 the FRAP and TEAC values of our samples are reported. The highest FRAP value (59.3 mmolFe2+/kg d.m.) was obtained for the Perla Rosso rice.

This cultivar is characterized by a red testa due to the presence of red colouring pigments. White rice (both Perla and Vialone Nano cvs) showed instead values of FRAP and TEAC similar between 156 - Tecnica Molitoria International - Yearly issue 2009

them and about 7 times less than the red rice. For oat and barley FRAP values were placed within the range 11.9714.24 mmolFe2+/kg d.m. Maize, rye and white rice gave results between 7.32 and 8.83 mmolFe2+/kg d.m. Spelt and emmer ranged between 4.52 and 6.15 mmolFe2+/kg d.m. The lowest values were attributed to durum wheat (3.04 and 3.10 mmolFe2+/kg d.m.), whereas soft wheat, the same as triticale, had a 2 fold higher value than durum wheat.

Serpen et al. (2008) examined total phenolics and flavonoids of 18 ancient wheat (12 emmer, 6 einkorn) and 2 bread wheat varieties grown in different regions of Turkey. Results showed that total antioxidant capacities measured by the ABTS assay, were generally significantly different in the emmer and einkorn groups: the highest total antioxidant activity was detected in the emmer samples (n = 12), suggesting that they may have high potential for utilization as a grain rich in natural antioxidants.

Regarding the TEAC values (tab. 1), as obtained for the FRAP assay, the rice sample Perla Rosso reached the highest value (46.18 mmol Trolox/kg d.m.). For all the other cereals, the TEAC values were found within the range of 2.46 mmol Trolox/kg d.m. for the cv Bionda oat and 5.62 mmol Trolox/kg d.m. for the cv Alamo barley.

Several Authors have demonstrated that the presence and distribution of bioactive compounds can be affected by several factors such as genetics, environmental and growing conditions or technical

processes such as milling and refining (Zielinski and Kozlowska, 2000; Adom et al., 2003). Emmons et al. (1999) investigated phytochemicals and the antioxidant activity of oat milling fractions measured by the ORAC (Oxygen Radical Absorbance Capacity) assay: their results indicate a high level of antioxidant phytonutrients for oat products. According to our FRAP results, oat samples positioned themselves on a high level in our range of values, even if this result is not matched by the correspondent TEAC values.

Since the synergistic interaction of the bioactive components present in grains is expected to give the total antioxidant power, we studied the most relevant classes of phytochemicals (i.e. phenolic acids, carotenoids, and lignans).

Hydroxycinnamic or phenolic acids represent another group of phytochemicals abundant in cereals (Andreasen et al., 2000; Adom et al., 2003; Zhou et al., 2004 a,b), which show antioxidant, phytoestrogenic, and other bioactivities that may offer health benefits. As

shown in tab. 2, we quantified total phenolic acids in soft and durum wheat, brown rice, whole grain emmer and maize. Phenolic acids are present in cereals as insoluble compounds mainly bound to the bran matrix, soluble esterified and soluble free. In all the samples, the insoluble bound fraction was the most relevant with values ranging from about 800 µg/g d.m. for durum wheat to about 2,400 µg/g d.m. for maize, whereas the soluble free fraction was very low (in the range 3 to 15 µg/g d.m.).

In all samples, ferulic acid was almost exclusively present in the insoluble bound fraction. In the soluble free and soluble esterified compounds, we identified sinapic acid, ferulic acid, caffeic acid, p-coumaric acid, vanillic acid and syringic acid. Kim et al. (2006) also studied the phenolic profiles of four different types of wheat. Higher concentrations of polyphenols were found in the outer layers of the kernel by Baublis et al. (2002).

Carotenoids are a widespread group of naturally occurring fat-soluble pigments, representing one of the major food

whole grains micronutrients in the human diet with many physiological functions. Data on the main carotenoids present in cereals, i.e. lutein, zeaxanthin, cryptoxanthin and β-carotene are reported in fig. 1 and fig. 2. In fig. 1 lutein+zeaxanthin, cryptoxanthin and β-carotene values for selected maize cultivars are reported.

These samples showed a very interesting profile with very high levels of lutein+zeaxanthin, compared to other cereals in fig. 2, and the presence of cryptoxanthin. Muzhingi et al. (2008) evaluated the major carotenoids in 36 genotypes of yellow maize by HPLC: the major carotenoids in yellow maize were identified to be all-trans lutein, cisisomers of lutein, all-trans-zeaxanthin, αand β-cryptoxanthin, all-trans β-carotene, 9-cis β-carotene and 13-cis β-carotene.

Apart from maize, lutein+zeaxhantin were

quantified in wheat, barley, oat, rye and triticale. For these cereals, a wide range was found, between 155.2 to 728.4 µg/100 g d.m. (fig. 2). Moreover an evident varietal difference was measured for both soft

and durum wheat. In rye, β-carotene was found in addition to lutein and zeaxanthin (fig. 2). In emmer and spelt it was possible to detect lutein only, ranging from 191.0 to 376.9 µg/100 g d.m.: the Padre Pio cv reached the highest value (fig. 2).

Serpen et al. (2008) found a high content of lutein, in particular, in einkorn which could be a new material for the development of high-lutein bakery products.

Regarding other relevant substances present in whole grains, in the last years the research attention has been focused on lignans, a class of compounds known mainly for the physiological properties of their metabolites, the enterolignans. In our selected cereals, secoisolariciresinol, matairesinol, pinoresinol, lariciresinol, isolariciresinol were identified and quantified. In tab.

3 the values of total lignans in selected cereal grains are reported. This value varies from 14.25 µg/100 g d.m. for maize to 490.22 µg/100 g d.m. for oat.

However, varietal differences were observed within the same species. For example, in rice a significant difference was observed between the cvs studied which are also known to have different technological properties.

It is also fundamental to underline that the contribution of each single lignan molecule to the total appears to be different for every single cereal species. It is also necessary to point out that in this investigation we didn’t quantify syringaresinol, which according to recent literature (Penalvo et al., 2005) is the most abundant lignan in maize cultivars.

Regarding the contribution of each single lignan, it is interesting to notice that in oat this is given by lariciresinol and pinoresinol. Considering that the conversion grade of lariciresinol and pinoresinol into enterodiol, biologically active metabolite of lignans, are reported to be respectively 101 and 55% (Heinonen et al., 2001), its compositional data make this cereal interesting as a source of potentially beneficial substances. In the same way, interesting results were obtained for barley, where the lignan compounds can be placed in the following decreasing order of concentration: lariciresinol>pino resinol>secoisolariciresinol. The lignan concentration in triticale (which is a cross between wheat and rye) exhibited total lignans levels closer to that of wheat than of rye (tab. 3).

CONCLUSIONS Several researches have recently focused their attention on the discovery of the many health benefits of wholegrain cereal foods, particularly in reducing the risk of diseases such as coronary heart

involved in the aboved mentioned benefits. The results showed a large variation in the kind and amount of bioactive substances present, both at the specific and at the varietal level.

For example if we take lignans measured in our study, oat and barley as a species could be a good source of these compounds but in rice the cv Vialone Nano gave values which are comparable with those of oat. In this regard and in attempt to correlate the results of the FRAP and TEAC tests with the contents of the molecules measured, we could say that barley as a species also gave high FRAP and TEAC values within the exhamined group of cereals.

whole grains Abstract Whole grains provide a wide range of nutrients and phytochemicals that may work synergistically to maintain human health. Lignans are a group of bioactive compounds widely distributed in cereals where they are mainly present in the outer layers of grains. Most dietary lignans are metabolized by the gut microflora to enterolactone and enterodiol, also known as enterolignans.

Enterolignans are compounds that exhibit estrogen-like activity. The content of lignans in cereal grains is affected by genetics, environment and growing conditions and, in foods, also by processing conditions.

Few results are reported in the literature regarding the effects of cereal processing technologies such as milling, baking, extrusion, etc. on lignans content in processed foods.

The objective of this research was the detection and quantification of lignans (secoisolariciresinol, matairesinol, pinoresinol, lariciresinol, isolariciresinol) in grains, flour fractions, pasta, breakfast cereals and other foods made with soft and durum wheat, oat and barley in order to investigate how processing affects the total level and the profile of lignans that reach the consumer.

INTRODUCTION Cereal products contribute to a balanced diet and recently several studies have assigned to cereal grains and to wholemeal cereal products a protective role in human health due to their content of bioactive compounds (Slavin, 2004). Despite the universal acceptance of the importance of grains in our diet and high consumer acceptance, usual intake is often below recommended levels. Whole grain consumption at breakfast could have an important impact on total daily nutrient intakes. So communication of whole grains importance in the diet is needed.

Whole grains provide a wide range of nutrients and phytochemicals that may work synergistically to maintain human health. The content of these compounds in grains Tecnica Molitoria International - Yearly issue 2009 - 163

whole grains is affected by genetic and growing conditions and, in foods, by processing conditions. Most grains are, infact, submitted to different kinds of processing to obtain a desirable product with optimized flavour, colour, texture and appearance, as well as shelf-life depending on the type of cereal and the eating habits of the consumers.

Processing techniques include milling, heat treatment, cooking, parboiling, or other techniques (Pedersen et al., 1989).

For example, commercial breakfast cereals are usually extruded, puffed, flaked, or otherwise altered to make a desirable product for consumers and to improve product quality.

In the milling process, the bran and germ are separated from the endosperm which is then ground into flour. Esposito et al.

(2005) showed that nutrients and phytochemicals are present with higher concentrations in the outer parts of the grain, so the refining process could reduce their content in the flours. Dimberg et al.

(1996) demonstrated that pearling time alters the antioxidant and phenolic content in the pearling fractions of oat groats.

Zheng et al. (1998) showed that micronization induced hydrophobic aggregation in legume proteins and both hydrophobic and disulfide bonds in cereals. A study of Yu et al. (2007) demonstrated that micronization can extend the use of barley flour in food products to increase fibre and beta-glucan content.

A study of Knuckles and Chiu (1995) reported that dry fractionation of barley produced a value added enriched prod164 - Tecnica Molitoria International - Yearly issue 2009

uct enhanced in components such as tocols, dietary fiber and β-glucans.

In order to produce food products with maximum health benefits, identification of food processing conditions that have an impact on the distribution, stability and activity of bioactive molecules in grains is needed.

Several studies have suggested that, within the group of cereal phytochemicals, the presence of lignans could be one of the factors that might explain the reduced incidence of certain chronic diseases in people consuming a diet rich in wholegrain products (Jacobs et al., 1998 a,b). Lignans represent a group of phytochemicals widely distributed in the human diet. Most dietary lignans are metabolized by the gut microflora to enterolactone and enterodiol, also known as enterolignans.

Enterolignans are compounds that exhibit estrogen-like activity. Concentrated sources of lignans include wholegrain wheat, wholegrain oats and rye meal (Adlercreutz and Mazur, 1997). Due to the association of lignan excretion with fibre intake, it is assumed that plant lignans are contained in the outer layers of the grain. These data suggest that wholegrain breads and cereals are the best means of delivering lignans in the diet.

As current processing techniques eliminate the bran fraction of the grain, lignans may not be found in processed grain products on the market and would only be found in wholegrain foods (Kilkkinen et al., 2001; Slavin, 2003). A complete database on content of lignans will allow researchers studying diet and disease to

quantify the intake of dietary lignans (Blitz et al., 2007). Stable isotope-dilution gas chromatography coupled with mass spectrometry was used to quantify six plant lignans in 86 food items commonly consumed in Japan (PeĂąalvo et al., 2008).

Few results are reported in the literature regarding the effects of processing technologies such as milling, baking, extrusion, etc. on lignans, so we focused our re-

search on the detection and quantification of lignans (secoisolariciresinol, matairesinol, pinoresinol, lariciresinol, isolariciresinol) in cereal grains and derived products such as flour fractions, pasta and breakfast cereals made with soft and durum wheat, oat and barley. The objective of this study was to investigate the effect of processing on the total level and on the profile of lignans that reach the consumer.

MATERIALS AND METHODS Samples and their preparation The analysed samples are reported in tab. 1. The barley fractions were obtained and provided by CRA-GPG, Fiorenzuola Dâ&#x20AC;&#x2122;Arda (PC), Italy. Barley grains were micronized in a KMX-500 device (100-200 kg/h; Separ Microsystem sas, Brescia, Italy). The obtained flour was fractioned by air classification with a SX-500 apparatus (Separ Microsystem sas, Brescia, Italy). The apparatus sorted out the flour in two portions: a coarse fraction and a fine fraction. The flour was sorted twice with the air classifier. For the analysis of lignans the following flour fractions were collected and studied: the coarse fraction obtained after the first air classification step, the coarse and fine fractions collected after the second air classification.

The soft and durum wheat fractions were produced and provided by CRASCV, S. Angelo Lodigiano (LO), Italy and CRA-QCE, Rome, Italy, respectively.

Three different brands of durum wheat semolina pasta, commonly consumed

in Italy, were purchased on the market. Semolina/20% oat flour pasta were produced and provided by CRA-QCE. A selection of cereal based foods, widely consumed in Italy at breakfast (breakfast cereals, wholegrain biscuits, puffed rice, puffed barley), were purchased on the market. All grains, milling fractions (apart from soft wheat flour), pasta and cereal based foods were ground in a refrigerated mill (Janke and Kunkec, Ika Labortechnik) and the flours were sieved to obtain a granulometry of 0.5 mm. The flours were then defatted with hexane and diethyl ether for 8 h in a Soxhlet apparatus.

Chemicals and Standards The organic solvents used for the separation of lignans were purchased from Carlo Erba, Milan, Italy. Pure organic solvents and chemicals used in the analytical procedures were purchased from Sigma-Aldrich, Milan, Italy. Lignans standards were purchased from Chemical Research, Rome, Italy.

EXTRACTION AND QUANTIFICATION OF LIGNANS Samples were extracted taking into account the methods of Obermeyer et al. (1995) and Milder et al. (2004). 12.0 mL of alkaline hydrolysis reagent (0.3 M NaOH in 70% MeOH) were added 166 - Tecnica Molitoria International - Yearly issue 2009

to 0.5 g of samples and, after stirring, were incubated for 1 h at 60°C. The samples were cooled down to room temperature and neutralized with 100% acetic acid (380 ¾L). The hydrolysate

was centrifuged (3,500 g, 10 min). An aliquot (2 mL) of supernatant was transferred into a test-tube. The supernatant was evaporated until only water was left (600 µL). Water (1.4 mL) was added together with 2 mL of sodium acetate buffer (0.05 M, pH 5.0) and then 400 µL of Helix Pomatia β glucuronidase/ sulphatase were added (β-glucuronidasi/ sulfatase S9626-10 KU Type H-1, 0,7 G solid, 14,200 units/G solid, Sigma in 10 mL of acetate buffer). The samples were incubated in a shaker water bath at 37°C for 24 h. Samples were evaporated to dryness and dissolved in 1 mL mobile phase. Quantitative analyses were performed on 50 µL extract using an ESAHPLC system (ESA, Chelmsford, MA, USA). The HPLC system used consisted of an ESA MODEL 540 autoinjector, an ESA MODEL 580 solvent delivery module with two pumps, an ESA 5600 eight-channels coulometric electrode array detector and the ESA coularray operating software which controlled all the equipment and carried out data processing. A Supelcosil LC-18 column (25 cm × 4.6 mm, 5 µm) with a Perisorb Supelguard LC-18 (Supelco, Milan, Italy)

was used. Chromatography was performed at 30°C, at a flow rate of 0.8 mL/ min using the following solvent system: solvent A, ammonium acetate 50 mM adjusted to pH 4 with glacial acetic acid; solvent B, methanol. The linear gradient used consisted of 28% solvent B, increasing to 30% over 4 min and to 40% over 41 min, held for 10 min. After that, returning to 28% solvent B over 3 min and monitoring this condition for 5 min.

The working potentials of the eight cells were set up at 60, 120, 200, 340, 480, 620, 760 and 900 mV. Sample peaks were analyzed by matching target peaks with standard peaks on the basis of their retention time and on accuracy ratio between adjacent channels.

Isolariciresinol, lariciresinol, secoisolariciresinol, pinoresinol, matairesinol were detected and quantified. In particular isolariciresinol and matairesinol were not identifiable for the presence of interfering compounds at the same retention time. The sum of identifiable lignans was indicated as total lignans. Values, expressed on dry matter, are in general the average of 3 determinations unless otherwise stated.

RESULTS AND DISCUSSION In tab. 2 the specific content of lignan compounds in the fractions obtained by micronization and classification (turboseparation) of two barley cvs, Alamo and Priora, is reported. These genotypes are hull-less barleys with differ-

ent β-glucan content and starch type: Priora has standard starch composition and amylose content, CDC Alamo is a waxy barley, with a very low amylose content and a high β-glucan content.

a whole grain and as a food ingredient for the production of processed foods (pasta, breakfast cereals, etc.) besides beer. Barley has an excellent nutritional composition and for its properties it could be used in a wide range of cereal-based food products as partial or total substitute of currently used cereal grains. Several studies have shown a high content of bioactive compounds (glucans and tocols) and a large range of antioxidant compounds having a phenolic structure in barley grains (McMurrough et al., 1996; Goupy et al., 1999). A review of Baik and Ullrich (2008) covers basic and general information on barley food use and barley grain processing.

Our results (tab. 2) show different levels of total lignan enrichment in both Alamo and Priora fractions with the coarse fraction both from the 1st and 2nd air classification being the richest.

In addition, the major contribution to the enrichment is due to lariciresinol in both cultivars.

In our previous studies, Alamo barley grains had a higher total lignans content than Priora grains (225.07 µg/100 g and 186.47 µg/100 g respectively, unpublished results). The same result is confirmed in this study where the micronized Alamo fraction has a significantly higher total lignans content than Priora.

This high total lignan content in Alamo matches the high β-glucan content found in this cultivar.

Several Authors studied air classification of grains. This technology has

been successfully utilized to produce fractions of barley and oat enriched in β-glucans (Marconi et al., 2003; Panfili et al., 2008). In particular Marconi et al. (2003) used air classification to obtain two fractions of barley (fine and coarse fractions) utilized to produce flour fractions enriched in β-glucans.

Verardo et al. (2008), studying the fine and the coarse fraction of barley, found that the coarse fraction had a larger concentration of flavan-3-ols (221%) with respect to the fine fraction. In addition, the coarse fraction showed the greatest antioxidant activity with respect to the whole meal and the fine fraction (Verardo et al., 2008).

Andersson et al. (2000), studying flour samples from seven different barleys obtained by air-classification, showed that the extractability of β-glucans decreased with increasing particle size, probably because of lower amounts of endogenous β-glucanases and poorer availability of the substrate in larger particles.

Casiraghi et al. (2006) evaluated postprandial responses to cereal products enriched with barley β-glucan. They used a concentrated β-glucan fraction obtained by air classification from a commercial variety Aliseo to prepare cookies and crackers.

Izydorczyk et al. (2008) demonstrated that the addition of 20% of barley fibrerich fractions to wheat flour used for manufacturing flat bread, provided substantial health benefits by significantly increasing the total and soluble dietary

fibre contents and by decreasing starch digestibility.

In the review by Hemery et al. (2007) on the existing processes that can be used for the production of wheat products and fractions with enhanced nutritional interest, it is clear that the germ and peripheral layers (bran) have considerable nutritional potential and contain most of the micronutrients, phytochemicals and fibre of the grain.

In this work, in both durum and soft wheat milling products (tab. 3), the fraction richest in total lignans was represented by bran. Lignans were also found in wheat bran layers (Mazur, 1998) and the major lignan was secoisolariciresinol diglucoside.

In this work a 4.87, 3.88, and 5.18 fold enrichment from the grains to the bran fractions was calculated in the soft wheat cv Bologna and in the durum wheat cvs Simeto and Creso respectively. In addition, it was possible to notice a selective enrichment of secoisolariciresinol, lariciresonol and pinoresinol from grain to bran. As example, in Bologna a 3.31, 5.93, 8.03 fold enrichment from grains to bran was calculated for lariciresinol, secoisolariciresinol, and pinoresinol respectively. It is interesting to notice that secoisolariciresinol was identifiable in soft wheat but it wasn’t in durum wheat, possibly because of its very low content.

Moreover, the total lignan content was higher in soft wheat than in durum wheat. Recently, Dinelli et al. (2007) described the distribution of lignans Tecnica Molitoria International - Yearly issue 2009 - 169

in four modern and six old Italian soft wheat cvs: secoisolariciresinol and pinoresinol were detected in all ten investigated soft wheat cultivars.

In soft wheat, lariciresinol clearly was the most representative lignan molecule. The comparison between the two durum wheat cultivars, Simeto and Creso, shows Simeto as having a lower level of lariciresinol compared to Creso in all fractions.

If we take into account the total lignans, it was possible to calculate a 5.72 and 8.31 fold enrichment from the grains to the external layers (middling plus bran), respectively in the Simeto and in the Creso cultivars. It is important to underline the fact that in our study the total lignans content of grains was mainly due to the lariciresinol value because we had problems for the identification of other lignans in the chromatograms, due to the interference of other molecules at the same time of retention.

So the total lignan content is clearly underestimated.

Cereal grain products with health benefits are an emergent part of the health related food market. The growth of the whole grain products is supported by the research, which is focusing on enlarging the range of healthy cereal products, thanks to the understanding of the mechanisms of whole grain health benefits. The development of products with high concentrations of nutrients as well as bioactive substances is essential for the delivery of benefits to the consumers. For this reason, it is important to determine their total amount in the whole grain, to understand the distribution of components within the grain and to investigate their variation as a consequence of processing.

In this work, we also wanted to evaluate whether cereal foods usually consumed at breakfast (breakfast cereals in particular) are a good source of lignans. Nesbitt and Thompson (1997), examining homemade and commercial products containing flaxseed, showed that the amount of lignans was linearly dependent on the percent flaxseed used but it was also influenced by other grains and the variety of flaxseed. In this work, a selection of products purchased on the market and widely consumed in Italy, showed total lignans levels ranging from 76.13 to 286.20 Âľg/100 g d.m. (tab. 4). The lignans content is clearly dependent on the new materials used (cereals and other materials), their degree of

refinement and, possibly, processing conditions.

The comparison of common semolina pasta and semolina pasta enriched with 20% oat flour showed that the addition of oat produced a 2 fold increase in the level of total lignans (tab.

5). This higher total lignans values is due to the higher level of pinoresinol in oat where it is the most representative lignan. In our previous studies oat grains from different cvs were identified as a good source of lignans with concentrations ranging from 312.72 Âľg/100 g d.m. to 571.41 Âľg/100 g d.m. (unpublished results).

However, the level of total lignans in commercial semolina pasta matched that observed in semolina from durum wheat grains. So the raw material and its degree of refining determines the amount of bioactive substances, lignans in particular, which are found in raw processed foods.

Further research is needed to study the influence on lignans of home cooking for those foods, such as pasta which are consumed in a cooked state and their bioavailability in humans.

pasta Abstract The firmness and stickiness of cooked spaghetti with different diameter were measured using a texture analyzer.

A strong correlation between the maximum cutting force (firmness) and the diameter of uncooked pasta (r=0.89) and the sensory evaluation of the firmness (r=0.91) was found.

The maximum adhesion force (stickiness) was also significantly correlated with chemical (TOM) (r=0.92) and sensorial (r=0.98) assessment of the stickiness. Two reference scales for instrumental evaluation of firmness and stickiness of spaghetti (1.7-1.8 mm diameter) were realized and proposed.

Key words: pasta, cooking quality, texture analyzer

INTRODUCTION The pasta cooking quality is certainly the sensorial property to which the consumers attribute more importance.

Consequently, several researches carried out on durum wheat pasta have been primarily addressed to elucidate and study the factors that influence cooking quality, and to the develop test for its evaluation. Cooking characteristics include firmness and stickiness. Bulkiness, is also important but it is strictly correlated to firmness. Pasta cooking characteristics can be determined by sensorial, chemical and instrumental methods.

Sensorial method Although, sensorial evaluation may be subject to individual bias, it still remains the most reliable test.

Generally, instrumental or chemical methods are not adequate to measure all the main pasta cooking quality markers.

174 - Tecnica Molitoria International - Yearly issue 2009

There is no a standardized method for the sensory assessment of cooking quality. Variables in the cooking test include kind of water, use of salt, ratio of water to pasta, cooking temperature and time, separation of the pasta from water, and sample preparation. Thus, the results can vary among different laboratories.

In Italian pasta manufacturing and research laboratories, a method based on the evaluation of the stickiness, firmness and bulkiness of pasta cooked at optimum cooking time, is widely accepted and applied (Cubadda, 1988).

Optimum cooking time corresponds to the disappearance of the white colour in the central core of the spaghetti. The test is carried out placing 100 g of spaghetti in 1 L of boiling tap water. After 6-8 min of cooking according to the diameter, a piece of pasta is removed from the cooking water at 30 sec. intervals and squeezed between two pieces of clear plastic or glass. When the white centre disappears, the pasta is immediately drained into a pasta strainer and then transferred into a dish. Stickiness, firmness and bulkiness were performed immediately by a group of at least three tasters according to the score scale reported in tab. 1.

The same reference scale can be used to evaluate the behaviour of spaghetti during overcooking.

However, some difficulties occur in sensory evaluation. One of the most important critical factors is the background and experience of the tasters. Another critical point consists in the correct application

of the criteria for evaluating the cooking quality and measuring the point scale.

In the United States, increase in volume or weight of pasta after cooking was used as indirect index of cooking quality. Normally, the cooked pasta weight is about three times the dry weight. The residue should not exceed 7-8% of the dry weight (AACC International, 2000).

Chemical method Starting from the assumption that pasta stickiness depends on substances escaping from the protein network and adhering to the surface of cooked pasta some Italian researchers (Dâ&#x20AC;&#x2122;Egidio et al., 1976; Dâ&#x20AC;&#x2122;Egidio et al., 1982), proposed a chemical method called Total Organic Matter (TOM), successively approved

by ICC as standard method N. 153.

TOM is the material released from pasta after cooking that is removed immersing the cooked pasta in water for a fixed time. After evaporation of the water, the total organic material released from pasta is chemically measured. The TOM method is able to measure only stickiness. Generally speaking, TOM values â&#x2030;Ľ2.1 g/100 g dry pasta correspond to

pasta high stickiness and low quality, values between 2.1 and 1.4 g/100 g predicted low stickiness and good quality, and values <1.4 g/100 g estimated very low stickiness and excellent quality.

Instrumental methods Several instrumental methods have been developed to determine one or more parameters of the pasta cooking quality. Matsuo and Irvine (1969, 1971) proposed a testing apparatus to characterize cooking quality using three parameters: tenderness index (T), which is related to bite; compressibility (C), related to firmness; and recovery (R), related to resilience. The three parameters are combined (R/(TxC)) to give a cooking score (Dexter et al., 1983).

Subsequently, many instrumental methods have been reported to assess firmness, resilience and tensile strength (Voisey and Larmond, 1973; Matsuo and Irvine, 1974; Feillet et al., 1977; Voisey et al., 1978; Walsh, 1971; Edwards et al., 1993).

A cutting procedure for firmness evaluation of cooked pasta and noodles using a texture analyzer equipped with data integration system and plastic tooth was approved by AACC as 66-50 method (Sissons et al., 2008).

Experimental test to assess spaghetti cooking quality using the texture analyzer In recent years we carried out several experimental tests using the TA-XT2i 176 - Tecnica Molitoria International - Yearly issue 2009

texture analyzer (Stable Micro Systems, Great Britain), addressed to: - study the effectiveness of the method for routine assessment of cooked spaghetti firmness and stickiness; - compare texture analyzer parameters with sensory judgment and TOM method; - identify an objective and reproducible scale for firmness and stickiness assessment of cooked spaghetti samples.

Firmness assessment Two different sets of spaghetti were used to assess the firmness of cooked spaghetti. The first one was composed of 67 commercial spaghetti samples of different thickness (1.4, 1.5, 1.7, 1.8, 2.0 and 2.2 mm). The second set was composed of 15 experimental spaghetti samples, manufactured with the same processing and possessing the same diameter (1.8 mm).

The preparation of the sample was carried out placing a 25 g portion of pasta in 300 mL boiling distilled water into a 500 mL beaker. When optimum cooking time was reached, the pasta sample was drained into a funnel and rinsed with stream of distilled water for 30 sec. The pasta was then transferred into a beaker of distilled water at room temperature.

The test was performed immediately after cooking to minimize changes resulting from storage in a liquid medium. Five strands of spaghetti were placed on the bottom place of the instrument and the measurement was carried out according to the AACC method 66-50.

Fig. 2 - Relationship between maximum force and spaghetti diameter obtained with 67 spaghetti samples assessed by texture analyzer.

Fig. 1 - A typical force-time curve with the main parameters (total work and maximum cutting force) to evaluate the spaghetti cooking firmness.

Cooking firmness is considered as the work in g/cm required to shear the five strands of spaghetti and a typical curve is reported in fig. 1.

Primarily, the effect of spaghetti diameter on maximum cutting force was investigated. The variability of the diameter in the 67 commercial spaghetti samples is shown in fig. 2.

The maximum force of spaghetti of 1.4 mm diameter is, on average, 222.4 g, compared to 382.6 g of spaghetti with 2.1 mm diameter. The correlation coefficient between diameter and maximum force is 0.89, P<0.01.

The maximum force is strongly influenced by spaghetti diameter. As a consequence, in the determination of pasta firmness using texture analyzer,

Fig. 3 - Relationship between sensorial firmness and maximum cutting force in 22 cooked spaghetti samples.

the spaghetti diameter should be considered.

From the population of commercial spaghetti samples, 22 ones having a similar thickness (1.7-1.8 mm) were selected.

The firmness of these samples were analyzed by the sensorial (Cubadda, 1988) and texture analyzer procedures. Fig. 3 Tecnica Molitoria International - Yearly issue 2009 - 177

pasta shows that the maximum cutting force values are highly correlated with sensorial scores (r<0.91, P<0.01).

The possibility to establish a score to distinguish the different classes of firmness quality was also studied. A classification score for spaghetti with 1.7-1.8 mm diameter is reported in tab. 2.

Stickiness Evaluation The texture analyzer was also used to evaluate the spaghetti stickiness; the data were compared with those obtained by sensorial and chemical methods. Fifteen experimental spaghetti samples of 1.8 mm diameter were analyzed. Spaghetti was processed in an experimental pasta making apparatus (NAMAD, Rome, Italy) according to the processing conditions reported by Cubadda et al., 2007.

The sample preparation was carried out according to the Approved Method AACC 66-50. The compression-retraction method using HDP/PFS pasta rig with a 5 kg load cell was adopted (Stable Micro Systems, Great Britain). The test speed was 0.5 mm/sec, whereas the pre-test Table 2 - Classification score of firmness determined by Texture Analyzer in spaghetti of 1.7-1.8 mm diameter. aximum cutting force M

and post-test speeds were 1.0 mm/sec and 10.0 mm/sec, respectively. The compression force was 1,000 g/sec. A typical force-time curve showing the characteristics of the adhesive test performed on cooked spaghetti is reported in fig. 4.

The maximum adhesion force (peak height of the force-time curve) and the work of adhesion force (area under the curve) are highlighted. Maximum adhesion force and total work, showing the same trend, can be both used as stickiness markers.

In tab. 3 the stickiness values of 15 spaghetti samples determined by sensorial, instrumental and chemical methods are reported.

The spaghetti samples covered a wide range of stickiness values in all the tests considered. Simple correlations between all variables (maximum adhesion force, sensorial score and TOM) were carried out. Maximum adhesion

cereal milling Advanced MILLING EQUIPMENT The GBS Group at Ipack-Ima 2009 introduces its equipment for the milling industry: 1) The new Rollermill Synthesis 150 which represents the ultimate technology for rollermills and is the result of combining constant research, development and of expertise established over 80 years of activity in the flour milling industry by three historical trade marks of the sector, Golfetto, Berga and Sangati. These are the credentials for the birth of Synthesis, a machine capable of satisfying the tightest sanitary standards, synonymous of milling precision and easy maintenance, versatile because of its modular construction that adapts itself to new plant needs. With its solid and elegant structure, Synthesis has a solid cast-iron base and parts in contact with the product are mainly made from hollow anodised aluminium alloy profiles, for thermal (condense) and acoustic insulation, or from stainless steel. The 6060 alloy fully complies with the UNI EM 602 European Standard. Its chemical composition is in fact specific for use in the food equipment manufacturing industry.

2) The Purifier “Semolina”: a new range of purifiers designed for cleaning and separating semolina where special emphasis was given to operator safety and sanitation and

to the design where minimal sharp edges were used.

Throughout the machine, rounded and streamlined profiles were used in order to achieve an extremely clean finish. Only first grade 60/60 aluminium alloy food grade extrusions and stainless steel was used in construction.

Depending on the coarseness of the product entering the machine, the new inlet distribution system can be easily set by means of an adjustable grid. This system ensures the even distribution of product onto the first sieves of “Semolina” in order to achieve the optimal purifying efficiency. In addition, the inlet box is automatically self purging once the machine stops.

“Semolina” also features a new system called Flyback. In traditional purifiers, due to their design, only the top sieves nearest the product inlet are loaded. The 2nd and 3rd rows of sieves are typically under loaded. This decreases the effective purifying area which in turn affects the final quality of the product. Flyback effectively overcomes this drawback and enables full usage of the 2nd and 3rd rows of sieves in this area.

The product is classified using the conventional method, namely 3 superimposed rows of 4 sieves each.

Tecnica Molitoria International - Yearly issue 2009 - 183

cereal milling

The sieve frames are also constructed in 60/60 aluminium alloy and the sieve cloth is attached by means of screws.

The sieve locking system has also been revised. Two reliable, sturdy spring-loaded swivel handles allow easy access to the sieve chamber. Each aspiration chamber is divided into 3 longitudinal sections with nine adjustment levers. In addition, there is a general adjustment lever for both sides of the machine.

This new design of regulating the air has enabled the number of transverse divider plates in the air chamber to be reduced to only 2 per side. This is a notable improvement from the traditional 14 dividers, and with fewer surfaces for the flour to attach to, it vastly improves the sanitary characteristics of the machine.

The purified product is collected in 2 satinfinished stainless steel hoppers. The product can also be directed to one or other of these

De-Branner mod.

PSV for wheat (GBS Group).

184 - Tecnica Molitoria International - Yearly issue 2009

hoppers by means of a manual flow selector. By-products are collected either in a single stream or in a “2x2” option selected via manual regulators.

Other than the inlet spout, no surface in contact with the product is painted. All contact surfaces are either extruded grade 60/60 aluminium alloy or stainless steel.

There are no welds in the construction of “Semolina” and only high quality stainless steel bolts are used in the assembly of the unit.

The 2 sections of the machine are mounted on rubber anti-vibration dampers. The vibrating action is achieved by means of 2 vibratory motors. Both sides of the machine are fitted with full length sight glasses which are effectively sealed to eliminate any dust leakage, a feature which is especially advantageous in areas with high risk of dust explosions like flour mills.

3) The De-Branner PSV/A 55. De-branning before grinding is becoming more important each day in the cereal processing industry, particularly when speaking of wheat. Product quality improvement and higher milling yields are usually conflicting targets, but this new technology makes it possible to satisfy them both. Numerous advantages are granted by this new method that offers great economical profits and benefits, deriving from: improved quality of the finished products; higher yields; elevated hygiene standards during all the phases of the process after debranning; space saving.

The main construction features of the de-branner are the following.

Machine structure: cast-iron, sturdy and vibration-free; the various parts are worked in a CNC machine, assuring a perfect coupling.

Product inlet: allows for a constant flow of product at the machine inlet.

Working area: formed by seven abrasive elements (grinding wheels) directly coupled to the shaft. The rotation of the grinding wheels and a proper regulation of the retaining bars ensure a homogeneous abrasion of the cereal.

Retaining bars: special anti-wear elements, positioned vertically on the machine body; the distance between the bars can be easily adjusted from the outside, even while the machine is running, and it can be checked by means of small graduated rods.

Cover: retains the cereal during the de-branning operation. It consists of four interchangeable elements in special anti-wear perforated sheet. The openings allow for the separation of the hull, which is removed by the grinding wheels.

Automatic management/control system: the level of de-branning depends directly on the dwelling time inside the grinding wheels working area. This time can be regulated by a breaking valve positioned at the machine outlet. In order to facilitate this operation and make it safer, the machine is equipped with a microprocessor which, by means of an electro-mechanical positioning piston, controls the movement of the breaking valve. The operator simply sets the required motor power absorption, and the system will react so as to reach it.

Aspiration: for proper operation the de-branner requires a suitable exhaust air flow: to ensure complete evacuation of the branny screenings, to clean the cover and to make the grinding wheels operation more effective.

4) One section of Plansichter Modulo: a new concept of plansifter with its aluminium alloy structure formed by the oscillating drive mechanism to which it is possible to attach from 2 to 10 sections (modules) having a wide range of sieve configuration (number, dimensions

The ejecting system is composed of solenoid valves to eject the non-complying product and air-filter-regulator group and condensate discharge unit.

The management and control system rely on microprocessors to control the sorting process and on software with self-zero-setting system and automatic and continuous control of the sorting performances.

veyors application: they eliminate the need for a bottom liner in the conveyor and reduce noise; they are easy to install or replace, cutting down the installation or maintenance costs. Available with L and T shape with 1 or 2 fixing holes or flights can be manufactured and attached according to customer specification. There is no welding required on the flights, no need to remove the chain from the conveyor for installation. It is easy simple and reliable.

Concerning the Atex regulations, Verdi suggests vent panels to be installed on silos, elevators, conveyors, filters, ovens, etc. (as an economical way to minimize explosion reaction).

Flat vent panels are recommended on applications that work in the same conditions as

the external air pressure such as bucket elevators or closed conveyor belts. Not recommended for heavy duty silos or filters.

The ribbed vent panels resist in heavier working conditions more than the flat vent panels.

The use of domed vent panels is recommended for heavy working conditions, both in pressure and depression conditions.

To avoid panel crashing in case of shock in depression working system, the use of a depression frame is needed inside the panel.

Verdi vent panels main features include: in accordance to ATEX regulations; made of stainless steel ASTM A240 (316L) or ASTM A240 (304L); with no 100% sintered PFTE gasket (or on customer specifications); with steel outer flange and fixing frame (provided on request).

Sea presents, at the Ipack-Ima international show in Milan, news about sorting technology. Sorting grains, and foodstuffs using colour separation technology ensures the highest accuracy in sorting coupled with a greatly reduced number of rejects. Added to this is the ability to process high capacities without sacrificing the final quality. That has already been proven and shown to the international market

Optical electronic colour sorter mod. Pixel (Sea).

by means of the Pixel series of colour sorting machine developed by Sea. Being able to achieve a consistently high quality standard is of key importance and also obvious is that a foodstuff must be offered â&#x20AC;&#x153;cleanâ&#x20AC;? from all defects that could compromise the quality of the end product. Optical electronic sorters offer a fast and safe solution to such a requirement by comparing and detecting any product displaying non-conforming colour with respect to the preset parameters. The optical system of the sorter automatically rejects this out-of-spec product with maximum precision.

Sea has installed and commissioned Pixel colour sorting machines in the wheat and rice industry and following this has identified the significant advantages that this type of sorting machine could bring to numerous industries not only in Europe. The machines are easy to use, offer low energy consumption and require minimum maintenance, adding to the productivity of production and other processes.

Pixel electronic colour sorters bring together the most modern technology and experience gained through many years in the industry. The machines use a control system with high resolution CCD cameras which incorporate the most advanced technology and yet, are simple to use. Up to ten cameras are used on the

different models to ensure optimum resolution.

While the actual machine is a standard design and configuration, the installation itself is always seen as a customised solution for each and every sorting application.

The Pixel sorter can be used to sort rice, wheat, and similar grains. There are three models available which are capable of handling from 0.5 to 35 tph. Typically, the machines are positioned within the first cleaning cycle of the process to identify foreign seeds, stones, and defective (mottled and shrivelled) grains. They are also used to identify and sort broken grains, to ensure the optimum quality of the end product.

Pixel sorters can be used for separation based on the colour or opacity/transparency of dry products. Sea offers a range of sorting machines working in monochrome, bi-chrome, NIR, IR, UV, resonance and others. The company has numerous references across a wide range of industries.

Three different ranges of sorters are available: the Echo, which has found a niche application for sorting shelled foodstuffs such as nuts; the Crystal for sorting glass products; and the Selekta for all other product/foodstuff sorting.

All Sea sorters can be divided into two sections working simultaneously and independently. The second section is normally used for the reject re-pass. Should the input product contain a high contamination rate, the second section can be used for an additional run of the product already sorted in the first section.

All sorters are equipped with a remote control system which enables the alter-

194 - Tecnica Molitoria International - Yearly issue 2009

ation and management of the operating software in real time. This means that, regardless of the location, our technicians are able to assess the situation and operate to alter the functionality and performance of the sorter.

Extreme flexibility, the outstanding efficiency of these sorters which reduce operational consumptions to a minimum, make the investment amortisable over a very short period of time.

Sea is able to offer absolute flexibility by providing a turnkey solution or working together with consultants, oems and the end users to ensure that specific application requirements are met.

The first Sea optical electronic colour sorting machine prototype was launched in Italy in 1968. This machine was designed for use in a rice sorting application. Following this success, machines were engineered for sorting other products, ranging from dried fruits to legumes and other foodstuff.

In 1989, with newly developed technologies available, machines were engineered for the recycling industry for colour sorting of plastic materials and glass cullet.

In 2004 a sorting machine using resonance was developed and has also found success.

on line analysis & dosing

INSTANT ANALYSIS of cereal quality parameters The Proteus, introduced by Esetek, is a modern NIT instrument which makes analysis more rapid.

Usually NIR technology is appreciated for the following reasons: no sample preparation; non destructive measurement, simple to operate, flexible instrument (multiple constituent and multiple matrices), affordable price, low maintenance cost.

Near Infrared Reflectance spectroscopy has been used to measure protein and moisture in flour and ground grains for over thirty years.

In the last ten years, Near Infrared Transmission spectrophotometers have proven successful in analysing protein and moisture in whole grains of wheat, barley and other cereals. They have replaced the reflectance analysers for measuring wheat and barley at receival silos.

The Proteus scans the wavelength region between 720 to 1,100 nm using a concave grating and a silicon diode array detector. The detector has 38 pixels spaced to read the spectrum at a data resolution of 10 nm. In this region of the NIR spectrum, protein absorbs at 1,018 nm, moisture at 967 nm and oil at 918 nm.

The Proteus provides istantant analysis measurement for quality parameters in Cereals: it is a low priced up-to-date and inexpensive NIT instrument. It also has an optical system with diode array future NIT (Near Infrared Transmission)

compact and robust structure. This ensures excellent stability and accuracy, quick and precise analyses of grains, oil seeds without requiring sample preparation. Up to six components can be measured simultaneously. The analyser is precalibrated, that is the mathematical relation between the spectrum and the amount of the sample components are determined by the producer based on a large sample set.

Its main features are: no warm-up time; measuring of whole seeds (wheat, durum, barley, rye, triticale, corn); measuring of seeds without grinding; measuring of the most important quality parameters: protein, moisture, gluten, fat; excellent accuracy and reproducibility; large LCD display.

DOSING systems and MOISTURE monitoring DS&M produces feeders and dosing systems, pneumatic suction units for all those industrial fields from the food to the bakery industries, from animal feeds to non-food industries, that is, where there is the need to dose and treat powder or granular raw materials even for difficult processing. DS&M celebrated its tenth anniversary of activity in 2008 and continues to renew production, applying the know-how acquired during these years in order to increase and differentiate the range of machines, small plants and complete automation systems production.

At Ipack-Ima fair the company presents, together with new products, also the production machines and innovations of other companies of this industrial field, now united with DS&M in the DS&M Group.

DS&M Group associates companies are already present with their machines in the treatment and handling of materials, both solids and liquids. To be part of a group of companies gives the possibility to be present in several different sectors of the raw material handling such as cereal and feed industries, oenology, water treatments; furthermore it also offers a greater variety of technological solutions, services and choices to the customers.

The two new machines, which are presented at the fair, are the feeder Dualfeed and the innovative humidity in line measurer Aqumeter.

The feeder Dualfeed represents an innovation in the dosing field and it is a successful solution for all the typical processing problems regarding powder materials, thanks to the technical characteristics, which differentiate it from all conventional feeders. The feed-

er Dualfeed grants a very high batch precision, an extended feed rate range and it incorporates the function of two different feeders in a single machine while maintaining a great accuracy in continuity in the gravimetric mode. The presence of two different dosing tools, which are controlled in an independent way, one from the other, and the presence of a high performing software for an easy control and an accurate and precise dosing, make the feeder Dualfeed unique.

The hoppers and the accessories range supplied are the same ones usually supplied with a DS&M standard feeder of the range BH. The other novelty is the humidity measurer Aqumeter.

The constant control of the humidity during the production phases is very important and the Aqumeter has been planned to control in a constant and continuous way the humidity grade of the products during the production phases and it gives the possibility to ad-

ticular, over the last three years, an innovative die for the compression screws has been designed which increases extrusion efficiency by 15%.

In addition, the assortment of presses now available boasts new models designed for simplifying the process, to go alongside the tested and proven system of the stabilization belt, technically up-dated and much appreciated for the ease of its operation, for the negligible energy input required and, above all, for the positive effects produced on the quality of the pasta.

There is a great deal of news as concerns the dryers as well: two new lines for special pasta have been added â&#x20AC;&#x201C; one for pre-cooked lasagna and the other for nests in containers and ribbons of pasta, thus offering a full range of products so as to satisfy every and any market demand.

The ventilation system has been improved for the long pasta lines, and the new dies for the pipes are now able to carry greater loads.

Furthermore, thanks to the improved treatment of the pasta, there is greater uniformity of the same during the packaging phase as well as during drying. The long pasta line varieties have also seen interesting developments with the introduction of the 5,000 kg/h standard using ITRG technology, which now accompanies the 6,000 kg/h standard, a consolidated standard for the company.

During the 2009 edition Fava is presenting some important achievements, some of the innovative details are available for viewing. Of particular interest are: a new compression unit complete with head and extruder; a line for ITRG long pasta for the production of 4,000 kg/h with a press having two special screw feeders; an up-dated and improved line supervisor, developed by the companyâ&#x20AC;&#x2122;s own software spe-

cialists, complete with software for the traceability of the product, interfaceable with the operational system of the pasta plant, and containing many other interesting and useful functions.

Storci presents a vast range of machines for special applications in the sector of fresh pasta and bakery goods as well.

An affiliate of Fava, today this company plays a leading role in various markets and sets long-ranging sights into the future, ready to take on new challenges.

The vast experience Storci has accrued, has made the company a leader in the creation of semi-automatic lines for the production of long, short and special pasta formats (production ranges from a minimum of 50 to a maximum of 500 kg/h) as well as lines for the production of fresh pasta, frozen foods, pre-cooked foods and semiautomatic couscous production lines (production ranges from 300 to 500 kg/h).

Storci looks toward the future, offering its services to study new production lines such as those for pasta-based ready-to-eat products, lines for gluten-free pasta, sanitary extruders for pre-cooked pastas and continuous kneading units for bread-making with special attention to the production of baked goods such as pastries and pizzas.

Their goals are varied and interesting, the outcome of years of experience which has led

to the current technical-commercial organization, feeding a corporate culture increasingly focused on custom made solutions in a sector where market standardization is less and less possible and time-to-market must be shorter than ever.

Important innovations in the production of fresh products are presented as well, in particular a line of ready-to-eat dishes apart from the Storci brand: the Omnia press for short, long and special pastas for production of up to 500 kg/h.

Fava presents a new compression unit complete with head and die, a line for long pasta able to produce 4,000 kg/h and an interesting up-dated line supervisor.

Technologies for FOOD PROCESSING In order to describe the high standard reached by the Brambati plants it would be necessary to retrace the steps of this Italian group that has been able to gain a following in the world bringing a continuous evolution to technologies in the milling field and in the plant engineering linked to the food product processing.

As regards the pasta industry, it supplies systems and plants for storing and cleaning semolina, mixing and recovering of powders, production lines feeding and recovering breakings and shorts.

As regards the confectionary industry, Brambati plant engineering is involved in raw material loading into silos, in pneumatic transport, in withdrawing from silos and in control and dosing systems, in weighting systems and batch preparation, in sugar milling and liquid management.

plants

Today the company is present in Europe and all over the world, from Australia to Canada, from The Far East to the United States.

This means being able to plan and build plants which are able to produce according to very different product standard and characteristics, as well as being able to respond adequately to the different technical and environmental regulations in force in the different Countries.

The ability to adapt productive standards to the different market needs has allowed this very significant presence. With a yearly invoicing which is over 20 million euro, today this group carries out 50 orders a year to which they add a constant activity of assistance and spare parts supply. But the most important thing â&#x20AC;&#x201C; according to the company â&#x20AC;&#x201C; is the invoicing quality, because the plants are present where high standards are re-

quired, where there is more respect for the local specificity, where it has been understood that the quality in the processes means quality of the products. Obviously the markets are evolving and requests change continuously.

This fact, which many consider a problem, is for Brambati the most significant point of force. Process governability, high level automation, plant flexibility, as well as the ability to respond with extreme accuracy to every single customer request is the true company core business.

Recently the group has been the co-protagonist of absolute excellent achievements, where factory needs and technical specifications have allowed to develop and to carry out in Avon, United States, one of the world’s most advanced pasta production plant, in particular as regards the net integrations.

This installation is made up of three operative zones: the silo tower, the production area and the packaging and grinding area. Such a challenging achievement has allowed the group to apply a great part of know-how, to a highly integrated productive cycle, where semolina arriving by rail is deferrized, sieved, filtered, and – through pneumatic transport in suction and compression – is loaded into the storing silos.

Accurately mixed, the semolina varieties are sent to the production area where they are transformed into pasta and successively packed. In the productive process there is a slight production waste which is anyway automatically recovered, ground and sent back to the silo tower again where it is ground and sieved again and put back in production.

This plant typology needs high technological knowledge due to its considerable problems, first of all the distance separating the wagon

loading station from the silo tower, the mixing area from the production and the packaging ones. To this is added the variety of the devices to control: there are hundreds of motors, more than 90 inverters, more than 100 electro-valves, soft starters, loading cells, scales, levels, sensors, sleeve filter control units, fire proof and explosion proof systems, manoeuver panels and many other tools. The complex problems have been solved by Brambati with a diagnostic and control centralization. There are two perfectly identical stations: one in the control room (production area), the other one in the silo tower. In these stations the operator can control and manoeuver the whole plant.

Moreover in the more remote packaging zones there are local management points made up of touch panels. To make the maintenance easier there are two portable consoles called “fly-

Tecnica Molitoria International - Yearly issue 2009 - 207

dry pasta production

ing disksâ&#x20AC;? to be connected to a series of doors placed all over the plant for the manual control of the local uses.

The secret of the success of the very good working of the plant is also guaranteed by an effective tele-assistance system, that is the plant remote control both at a software and hardware level from the Brambati offices for a ready intervention in case of a breakdown, but also for periodical check operations or for technical help for the operators manoeuvers.

All this requires integrated nets and distributed architecture. It is a highly technological project, with which it is possible to connect the production areas from PLC to all its expansions, to easily control and manage the intelligent devices activity (inverters, electro-valves, and scales). These are extremely complex processes, which have been realized paying particular attention to the simplicity of the operator interfaces towards the plant.

This dialogue simplicity is expressed both at plant control level (alarms, productive flux), and for hardware and software diagnostic interventions. But the most relevant aspects regard the recipe management, which takes place with complete flexibility, and the high level in the report and document sections.

Nowadays the traceability regulations in force require being able to go back to the product origin starting from its packaging. The automation and informatics processes activated make this operation easy and completely coordinated with the production ones. In a Brambati plant the product is identified, codified and followed step by step until packaged. Every single lot of production is identified by a proper specific code through which it is possible to get a wide series of information. These provisions

208 - Tecnica Molitoria International - Yearly issue 2009

represent a great warranty for the consumer as well as for the companies which commercialize the product. This system allows to trace back to the origin of an unfit supply and enables the companies to have a better purchase control and monitoring.

This actual Brambati group leadership has a tradition which dates back to 1945 with the founder Francesco Brambati. Since the 1960s, when the company stared co-operating with Sciev, they have been able to continuously propose innovative solutions and have been able to capitalize this experience, which is today an incomparable inheritance of knowledge.

In the 1970s, with the birth of Brambati Automazione, the group has faced the challenges of the new millennium being in advance as regards the assumptions of the informatics era â&#x20AC;&#x153;technological revolutionâ&#x20AC;?.

For years the proven synergy among the group companies represents a success formula, the different competences are integrated. All this has allowed a constant evolution in terms of technology and the very high modularity and flexibility of proposals. The Brambati group has been able to develop knowledge and a constant ability to plan, but it has mainly been able to understand the customer needs and many times it has anticipated requests. This thanks to the use of resources destined to research; in fact the group has been cooperating with the Universities of Genoa and Pavia for years, creating a testing space which makes the companies not only a place where the existing technologies are applied, but also places where solutions and synergies for the future are imagined and materialized.

production

The machine mod. La Parmigiana C301, for the production of short pasta (400 kg/h of fresh product) has been designed by La Parmigiana company to satisfy the needs of laboratories that want to produce high quality fresh or dry pasta and for 24 hour continuous (or not) productions. This machine can be coupled to nest forming machines, lasagne producing machines or shearing machines to produce special kinds of pasta and filled pasta. This model is provided with a tubular profile frame mounted on legs, with an anti-chute aluminium floor.

The mixing hopper, supplied with a vacuum system, is fed by a premixing-homogenizer group, composed of a centrifugal premixer

complete with: flour holder with feeding control probes, water doser by direct injection system with proportional electronic valve controlled by the PLC with digital programmation and flour doser by means of a volumetric system with high precision screw controlled by the PLC on the machine. This group is coupled to a homogenizer unit. The dough passage from the homogenizer unit to the hopper with the vacuum system is through a rotating valve for vacuum tight (case-work). The chosen solution allows to reach, during the hydration phase, a longer stay of pasta in the hopper with vacuum. The result is a better colour of pasta.

On the cover of the hopper, made of transpar-

ent material, there are the level probes that manage the cycle from the premixer to the extrusion screw automatically.

The endless screw, in special quality steel, with high efficiency profile and low thermal inertia, shows a considerable resistance and thanks to the three threaded ends coupled to the screw’s geometry makes it possible to reach a very good performance with low turn rating. It is possible to vary the endless screw speed by an inverter.

The head for vertical extrusion, in stainless steel fusion Aisi 316, allows a good compensation of all the pasta shapes and it is supplied with a direct ventilation from the cutting device to the cut area.

The lateral die extraction is made by means of a pneumatic piston. The automatic cutting device for short pasta, using brushless technology, is with a direct-connected motor and the speed can be adjusted through the keyboard.

This machine, with PLC data and a recipes management display, is on the upper floor.

The main control cabinet is positioned on the floor, with user link by profibus line: everything is controlled by PLC and an integrated push-botton panel. The working logic provides a wide range of controls such as: speed

Dryers, COUSCOUS AND PASTA Ipack Ima 2009 is the opportunity for Clextral to introduce its new range of optimized Evolum Rotante dryers and Evolum couscous lines from 1,800 to 3,600 kg/h. A lab-scale Evolum 25 twin screw extruder is also exhibited on the booth.Well known indeed for its expertise and world leadership in twin screw extrusion, drying and couscous turn-key production lines, Clextral keeps on improving its equipment and technology in close collaboration with its customers and with research and technical centers.

A long-term partnership set up with the Cetiat (Technical Center for Aeraulics and Thermal Industries: a study, testing and calibra-

214 - Tecnica Molitoria International - Yearly issue 2009

tion laboratory in the fields of aerodynamics and fluid mechanics, heat sciences and acoustics) allowed the company to develop a new dryer: the Evolum single pass belt dryer.

This dryer is now used by worldwide customers for drying various types of extruded products in ranges from 300 to 1,200 kg/h. The studies carried on this occasion led the R&D team to make some improvements in the design of the existing Rotante dryer to optimize its drying and energy efficiency. This dryer is used successfully since many years in the pasta, couscous and pellets production lines supplied by the company as well as for drying several other products like bulgur, cereal

based functional ingredients, phytosanitary products, fruits, rice, etc.

The Rotante drying technology is a perfect tool for fast, homogenous drying that meets the stringent requirements for product quality and reduced production costs. This dryer has indeed distinctive features that ensure complete homogeneity of drying with less energy consumption. The distinctiveness of the Rotante technology is due to its simple and ingenious design. It transfers product through drying with uninterrupted Archimedes screws mounted in a fixed position on a rotating drum. Each time the drum achieves a full rotation, the product advances simultaneously one step along the screws.

This specific design key feature of Clextral Rotante technology guarantees more homogeneity of products drying compared to other systems thanks to: continuous and smooth gentle product mix throughout the drying process; mastered drying barema; unique residence time; no cross contamination of products.

The production cost is therefore reduced thanks to: the accurate mastering of the drying barema leading to a heterogeneity of drying approaching 0; an extremely high energetic efficiency from 88 to 92%, much higher than the standards of the food industry (belt drying is estimated to 55 to 70%,) has been confirmed by the measures taken by the Cetiat with running users; almost no maintenance costs either in terms of budget of spare parts and time dedicated for cleaning; the optimization of the equipment thanks to continuous recycling system.

Another key feature of the dryer is the fines recovery system. The regulated air speed from the circulation fans is around 6 m/s to avoid dust stagnation in the upper part of the assembly. Fines fall down the smooth, angled stain-

less steel walls below and are channeled to two screws, which continuously extract them at the dryer base. All fines are recovered for reuse, with no heat degradation, which can occur on traditional dryers.

The Rotante userfriendlyness and easy maintenance are guaranteed by: quick changeover of products (5 minutes between 2 shapes); possibility to dry 2 different products in the same dryer without cross contamination and with different drying conditions; easy and reduced maintenance thanks to immediate access to the mechanical parts (out the drying ambiance); robustness and material resistance to extremely high temperatures. All mechanical components being located outside the drier drum combined with the all-stainless steel design of the drum, contributes to high reliability and easy maintenance; quick set up on site, only 3 days in normal conditions.

In order to meet each customerâ&#x20AC;&#x2122;s require-

ments, Rotante technology is modular and can be built in accordance with product/flow rate customer requirements. The new Evolum Rotante ranges from 6 to 10 fans and from 10 to 20 Archimedeâ&#x20AC;&#x2122;s screws (6V10 to 10V10).

Clextral keeps on bringing something new also in the couscous process. In fact, this Rotante dryer is particularly efficient in the industrial couscous process. The throughputs offered now by the company range from the optimized new range of Evolum CC18 and CC36 (respectively 1,800 and 3,600 kg/h) offering new potentials to couscous producers in addition to the famous CC1200 with increased efficiency to 1,300kg/h and even a brand new CC 300-500 Smart Line.

The majors improvements of these new Evolum couscous lines are of course the use of the Evolum Rotante dryer and also the improved energetic efficiency of the couscous steam cooker which is recognized for its high efficiency in terms of product quality: the higher couscous swelling rate on the market is indeed a guarantee that the final product quality is the highest.

Thanks to its mastered process with years of experience and more than 60 lines running worldwide, Clextral couscous production lines allow the use of various types of raw materials from traditional durum wheat semolina

216 - Tecnica Molitoria International - Yearly issue 2009

to soft wheat, corn, rice, barley, oat, etc. The perfect tool for opening new trendy markets for couscous processors.

As far as its pasta production lines are concerned, Clextral recommends and optimized the use of the Evolum Rotante dryer in its traditional range of short pasta lines now standardized for increased capacities from 1,100, 1,400, 1,800 to 3,000 kg/h.

It is possible to test the performance of this technology in the Clextral Research Center in France. While for direct assistance Clextral has subsidiaries and offices in Algeria, Australia, Chili, China, Russia, Usa.

production

In the last 15 years, despite the not always favourable economic situation, the Italian food technology industry has had particularly positive results, both in terms of total turnover and exports. Since the 1970s, this sector in Italy has shown an increase in production of about 300%, and in the same period exports have doubled every 5 years.

But in this favourable scenario there has been no corresponding technological progress: except for a few marginal improvements, the current technology is the same as that used 30 years ago.

It is only recently that a new system has been introduced to the fresh pasta market. Called PI-LAR, and originating from Italiana Teknologie, it has been indicated by many players in the sector as the â&#x20AC;&#x153;new wayâ&#x20AC;? for the production of fresh pasta.

PI-LAR permits the elimination of the classic kneading and rolling activities, and allows the dough to be structured, mixed and rolled out in a single passage, using a pair of cylindrical rollers. The reduced rotation speed (from 1 to 4 revs per minute) allows the system to

220 - Tecnica Molitoria International - Yearly issue 2009

perform a complex fluidodynamic operation that includes: a low deformation rate of the dough, rollers that apply a minimal pressure gradient and a significantly isothermal flow of the pasta sheet.

This is made possible by the following special configuration and design features of the system: it maintains the pasta sheet at a constant temperature during the cold rolling, it optimises the mixing system by continuous management of the rotation speed, it uses a mixing chamber of the correct size and section, and it uses the correct number of exclusively designed mixing paddles in the optimum positions.

The auto-feed mechanism enables the system to avoid applying too much pressure during rolling of the pasta. In fact, the entire production cycle avoids mechanical stress, with a consequent absence of temperature rise in the dough. In this way one of the major causes of quality loss in the pasta sheet is avoided.

This is particularly important because it gives the system the significant advantage of being

able to reintroduce waste and surplus dough to the production process, maintaining its organoleptic characteristics at the highest level: the pasta sheet preserves its original colour, and becomes neither sour nor sticky, remaining soft and elastic.

The total absence of waste at the end of the daily production cycle is particularly important, because it enables a significant saving in raw materials, and also because unused waste must be collected and managed, with all the additional costs that this entails.

But there are other advantages, too. The system ensures: an increase in shelf life to values until now never reached, unthinkable with the current technology in use: fresh non-filled egg pasta keeps for 30 to 45 days at room temperature; for fresh filled egg pasta, the shelf life is increased by up to 500%, depending on the type of filling; extreme simplification of some processes: lasagne and cannelloni can be made without boiling the pasta; high starch retention capacity during cooking preventing stickiness, the defect least tolerated by consumers; packaged, ready-to-eat or pre-cooked pastas do not absorb the water in the accompanying sauce or the preserving liquid, once again extending the shelf life; significant reduction in the return of packaged products; there is no need to use either open- or closedcircuit cooling (chiller); greater cooking uniformity and stronger pasta, even when it is as much as 300% overcooked; an increase of up to 30% in the specific weight with respect to traditional products;

the ability to eliminate flour dust in the pasta preparation environment.

With PI-LAR, Italiana Teknologie not only brings advantages to the production of classic pasta, but also allows to develop pasta sheets with completely new characteristics, impossible to achieve with any other process currently in use.

The creation of multi-coloured pasta is simple. The paste, in a variety of colours, is added in the correct proportions to the dough. This gives a coloured pasta sheet of the configured thickness, an attractive colour range, not obtainable with current processes.

Production changes require just a few seconds, and still needing only one rolling.

In addition, the system can be configured to produce coarse pasta, in a process that guarantees a colour uniformity without any streaks, unlike conventional systems which tend to bleach and to damage the product by compressing the dry wrinkles present in fresh pasta, without offering any advantages in terms of absorption of the sauce apart from that of producing a simple visual effect.

In conclusion, the research performed by Italiana Teknologie has developed in the direction of a broad rationalisation of the production systems, resulting in elimination of around 70% of the components. This provides an enormous reduction in production costs, significant reductions in energy consumption, resizing of the workforce, maintenance reduced to a minimum, increased passive safety and overall sanitation, and maximised hygiene.

trol and management of electric power systems as well as industrial automation, providing customers with the planning and development of integrated solutions that improve the effectiveness and efficiency of their complex manufacturing processes. The companyâ&#x20AC;&#x2122;s mission is to develop software solutions for the control of the entire industrial process: from administration, to production and distribution.

Divella, one of the most important and qualified Italian pasta producers for over 120 years, has chosen RAM Elettronica for the automation and control of its productive processes. It has recently automated two new systems: fresh pasta and biscuit making.

These are modern, technological, state-of-theart systems for which the quality of the product is strictly tied to a well-controlled and monitored production process.

RAM Elettronica, following up on its solid experience in the sector, has therefore created its production process control system for these new scenarios.

The proposed SCADA System is an integrated

Management loading silos (RAM Elettronica).

system that provides through the use of a single instrument for the entire process, without being forced to use different systems.

In fact, this is how the RAM System guarantees the Traceability of Batches as required by current regulations.

The process control system and software has been created for fresh pasta.

The SCADA System follows the production process from its onset, namely the arrival of the raw material, up to the finished product that is ready for packaging; furthermore, in addition to process control in the field, it regulates and monitors all of the development stages of the production with its tracking system, through which the distinct bases of the products, the production rules, and the operation plan (task scheduler) can be defined.

The system interfaces with external devices such as barcode readers, RFID, and PDA for the acquisition or sending of data.

In addition, the SCADA System can export data to external MES systems for the statistical storage of data.

It is important to mention that all of this is in a single integrated system.

The process control system and software has been created also for biscuit making.

The SCADA System follows the production process from its onset, namely the feeding of the raw materials, up to the management of the mixers; furthermore, in addition to process control in the field, it regulates and monitors all of the development stages of the production with its tracking system, through which the distinct bases of the products, the production rules, and the operation plan (task scheduler) can be defined.

The integrated tracking system, in addition to the establishment of separate product bases, also provides the definition and control of each production phase (batch) by providing a sophisticated and customizable system for the control of the production phases.

The winning key at Divella is having a single integrated, modular, and customizable control system entirely achieved by RAM. This guarantees the full control of the product

by RAM and the continuous evolution of the product itself.

Moreover, the following systems were realized, in collaboration with other suppliers of machinery for the food sector, for the creation of the new F. Divella plants.

Fresh pasta sector: raw material storage silos, regional pasta line, long pasta line, egg system; biscuit making sector: raw material storage silos, 5 mixers, egg system; general system design: special local temperatures control, boiler, pump room; storage silo loading from mill.

With respect to the above, RAM Elettronica has realized the electrical system design, panel design, panel creation, system creation, first level SW creation, and second level SW creation.

SACKING

Calloni began as a cottage industry more than 40 years ago in Arconate, producing woven material for third parties, in the 1970s the production of cloth sacks for rice was begun and the use of synthetic fibres has also introduced. That was a long time ago, technology has grown and so has the company production that now ranges from yarn to cloth to finished sacks.

Everything begins with thread: particular machinery transforms polyethylene and polypropylene granules into raffia thread, which is sold, in part, into various sectors and also into cloth to make sacks. With jute, cotton and synthetic fabric more than 400 different types of sacks, personalized with phrases, trademarks and designs with a choice of up to 4 colours are created. Artwork is produced with avantgarde computer graphics, that allow high-definition printing on cloth.

BAGGING MACHINE

During Ipack-Ima 2009, Elcu Sud exhibits the brand new universal bagging machine model RC100.

This newly designed machine introduces, for the first time, the idea of “flexible bagging”, that consists in both low and very high production capabilities (up to 900 bags/h) with no need for additional devices.

Flexibility of the machine means that fluctuation of monthly/daily production volume

230 - Tecnica Molitoria International - Yearly issue 2009

caused by the variation in demand has now been solved thanks to model RC100. Furthermore flexibility in machine manufacture means a huge saving and therefore reduced selling prices.

RC100 can work with many different types of open mouth bags (paper, raffia, plastic, etc.) and different types of products to be bagged like stable products (such as granular of different kinds) and unstable products (such as

powders of all kinds, aerated powders, etc.).

Technological innovation and flexibility makes the bagging machine model RC100 an essential machinery for future conceptions of production, where the keywords are â&#x20AC;&#x153;be flexible and reduce costsâ&#x20AC;?.

Elcu Sud shows the new bagging machine model RC85, which works with double folding plus hot-melt.

BAGGING SYSTEM and anthropomorphic At Ipack-Ima, the Concetti Group presents the IGF bagging system line and two other new machines: Continua FSS and the Articulated Robotic Palletiser.

Continua FFS is the modern bagging system that forms, fills and seals bags obtained from thermoplastic tubular reel thus granting the client an economic benefit due to the workforce reduction and to the non-stop utilization of the plant, thanks to the long-lasting autonomy of the reel.

The different models of this line have been designed to perform both small and large manufacturing outpouring, from 400 to 2,000 bags/hour, depending on the product. Adaptable, completely automatic, Continua can work both flat and gusseted reels of different materials and different bag widths, both in PE and PP, aluminated and compound.

The operative stages and the standards variations, like the size change, can be carried out in the strictest time, avoiding any operator intervention because of the PLC-management.

The Continua is available also in stainless steel for the outpouring of corrosive products and, in particular, hard environmental conditions.

This machine has been designed to work different families of product, such as:

PALLETISER

Chemical (plastic granules, salt, basic chemical powders).

Building materials and minerals (sand, readymixed, cement mortar).

Agricultural products and animal feed (fertilizers, seeds, pet food, vitamin-enriched supplement, cat litters).

Human alimentation, basic products (sugar, wheat, yeast).

Continua FFS bagging system (Concetti).

Tecnica Molitoria International - Yearly issue 2009 - 231

bag filling & sewing

Many different options, e.g. the possibility to insert one or two handles while the bag is being formed, enable to set up and customize the Continua for every potential project, thus satisfying the needs and the technical innovations requested by the clients.

When required, the Continua can be assembled on a mobile motorized platform with an air-cushion system, oil dynamic or on tracks with rails, and can therefore be positioned and connected under many unloaded hoppers in order to bag different kinds of products.

The Articulated Robotic Palletiser is the latest all-purpose model in the range of Concetti robotics palletisers.

It can quickly work bags containing stable, aerated or fluid materials, allowing the partial overlapping of the bag edges. The machine is equipped with a solidly built bustling pneumatic articulation, mounted on a rotating basis composed of one arm and one forearm. At the end of the arm, a rotating joint holds the pliers which can rotate around its vertical axis.

The arm picks up the bags one by one from the roller conveyor and lays them on a specific point assigned by the program.

The arm can be tilted so that the pliers can pick up the bags from the roller conveyor; then it is lifted up so as to allow free rotation around its main body. Rotating the pliers on its own axis places the bag in the position assigned by the planned palletising schedule.

The arm is positioned to share time and pliers open in order to lay the bag on the pallet in training.

At this point, the arm returns to the starting position and it is ready for a new cycle.

The solution gives the palletising system specific anthropomorphic characteristics: flexibility, versatility and manoeuvrability thanks to the keyboard with joystick.

232 - Tecnica Molitoria International - Yearly issue 2009

Articulated Robotic Palletiser (Concetti).

Available with the advanced optional configuration having two lines serving the respective pallet on the ground, or with the empty pallet magazine and full pallet evacuation roller conveyor versions.

The extremely small size enables the installation of the Articulated Robotic Palletiser in places where the positioning of a palletising system would not be possible.

The machine is equipped with a PC-controlled system. Through proper programs it is possible to run the machine using virtually any kind of palletising scheme.

The format change and the program change are performed rapidly and automatically.

The Concetti Group equipments and systems can be divided into the following categories: Weighing systems.

IGF large size bagging systems up to 1,500 bags/h.

IPF small size bagging systems up to 2,400 bags/h.

IMF medium size bagging systems up to 1,200 bags/h.

FFS Continua up to 2,000 bags/h.

FLOUR BAGGING Umbra Packaging, having been specialized for years in the manufacture of packaging machines for bagging bulk products in openmouth bags, has recently begun a project which aim is to revolutionise the technology used in milling industry packaging.

The need to substitute the classic valve bag for flour packaging with a sealable typology, in order to avoid the contamination of the product with foreign materials, has become a consolidated necessity. The evolution, which has already taken place in other sectors where packaging has become a source of added value for many products, has even presented itself in the milling industry, a sector that has been influenced by a strong contraction of production and by increasing competitiveness.

The solution proposed takes into consideration the particular needs which derive from the production of flour foodstuffs and collateral products, as well as the possibility of diversifying both the products offered, as well as their nature (organic products, special flour mixtures, grain mixtures, flakes, etc.).

But the true added value of this system is its great flexibility of use with regards to the formats it is capable of putting on the market (small packages for large-scale retail, mediumsize formats for the workplace, and large formats for bread-making and export, etc.). This

High level, low level and robot palletising systems up to 2,400 bags/h.

Big Bag systems up to 70 big bags/h.

(Concetti - S.S. 75 Centrale Umbra km 4,190 - Fraz. Ospedalicchio - 06083 Bastia Umbra - PG - Italy - Fax +39 075 8000894 - www. concetti.com)

machine flexibility allows producers to quickly package in any size, from 2 to 50 kg, accurately, without influencing system productivity.

The bagging machine is automatically selfadjusting at size change, allowing the operators to save time, as well as to make the most of the system for packaging even small batches of different products, in various packaging shapes.

The modularity of the bag-closing line renders it useful for various purposes, even simultaneously, based on future market demand, such as: stitching with crĂŞpe paper; stitching with edge folding; folding with upper-edge glue restoration (pinch-top bag); application of an adhesive paper covering over the stitching; special heat-sealing units for resin-coated paper bags and paired-material bags such as polyester + PE (laminated bags), polyester + aluminium + PE (metallized bags), aluminium + PE (barrier bags).

The so-called â&#x20AC;&#x153;pinch-topâ&#x20AC;? bag, which is currently the most utilised in the milling industry, deserves special attention amongst openmouth bag typologies; in fact, this bag, equipped with lateral side gussets and a glued bottom, has the useful quality of tak-

Tecnica Molitoria International - Yearly issue 2009 - 233

bag filling & sewing

ing on an absolutely regular parallelepiped shape once it has been filled, quite similar to that which occurs with the classic valve bag.

This contributes to simplifying the bag typology substitution process. In fact, by maintaining the same size and shape, subsequent palletising operations remain unaltered.

From a marketing point of view, the result of such a change is only perceptible on an aesthetic level, while from a product quality point of view, the possibility of offering customers a perfectly sealed bag, which guarantees hygiene and longer shelf life, is significant.

Umbra Packaging, making the most of the experience acquired in the production of bag sealing systems, has designed its own closure system for â&#x20AC;&#x153;pinch-topâ&#x20AC;? bags which is capable of ensuring a perfectly air-tight and aesthetically pleasing seal for any bag format.

The productive capacity of the mod. UPD1500 system, with regards to flour for the

Flour packaging machine (Umbra Packaging).

234 - Tecnica Molitoria International - Yearly issue 2009

food sector, can reach a maximum of 1,000 bags/hour for the larger formats.

The technical choice, based on a step-bystep movement in-line machine, is the natural development of the well known packers for 1 kg flour bag usually used in this field, which fills the product using more than one spout and treats the bags on several consecutive stations and is able to reach relevant throughput with high and constant quality results. The UDP-1500 summarises the above described characteristics with the typical high flexibility of all Umbra Packaging machines.

The extremely diffused auto-diagnostics system, which is guaranteed by its ASI BUS network wiring, together with the possibility of connecting the machine to the customer care offices via modem, reduces maintenance times to a minimum by facilitating the identification of any eventual malfunc-

tions which may cause the system to stop functioning.

In conclusion, reliability and flexibility are the two main characteristics of Umbra Packaging bagging lines. These characteristics render the systems easily customisable, even for the most

demanding requirements, without having to sacrifice what has become the compelling necessity to increase production in terms of weight.

The equipment includes the unique ET/2 valve bag sealer, which has achieved much success Automatic high speed packaging line mod. Speed 5-10 (Technipes).

BAG FILLERS

due to its innovative method of bag sealing via hot-melt glue and paper. The packing line is fully automatic and requires no manual adjustment to change the bag size. Ultrasonic sealing is also offered for these packing systems.

The Speed 5-10 is Technipes latest automatic high speed packaging line for 5-10 kg premade bags with hot-melt glue sealing system.

Fully innovative, it stands out in its segment due to the completely new design concept, including use of brushless dc motors. The in-line step-by-step system divides the bag packing process into separate operations. The Speed 5-10 allows for the dosing and packaging of 5-10 kg bags with floury or granular products. The final brick style form may be optioned with a single or double fold hot-melt glue closure. The result is definitive, perfectly square bags with optimum aesthetic appeal.

For open-mouth bags, the Futura model is the most updated automatic bagging and sealing solution developed by Technipes, revised to boost simplicity and operator ease-of-use.

The machine primary advantage is the compact design without sacrificing performance, reaching up to 600 bags/hour with free-flowing products. Bag size changeover is fully automated, and occurs in a few seconds.

Imp.a.c., leader in the production of automatic systems all over the world, counts in its wide range of machines a high quality low level palletizer. The machine, assembled with innovative technologies and experimented successfully, provides high production standards and satisfies all customer requirements.

This low level palletizer has an extraordinary working capacity of 1,200 bags/hour.

Equipped with layer tightening guides at the

238 - Tecnica Molitoria International - Yearly issue 2009

sides and bag/layer flattening on top, the machinery creates squared and stable pallets, also using the infra-layer sheets.

The change format regulations can be completely automatic, reducing the operator to only overseeing the functioning.

In order to complete the full pallet storage phase, the company suggests the utilization of the Imp.a.c. hooder; the machine has a production capacity of 100 pallet/hour, ide-

Low level palletizer mod. 12/1A (Imp.a.c.).

al for high productions. The hooding process gives more stability and protection to the full pallet, reducing the wrapping film consumption, providing customized film and avoiding wrapping imperfections at the edges. The automatic HCS (Hooding Centering System) simplifies the pallet positional and dimensional detection. Using this innovative device, the machinery adjusts itself to the current pallet format reducing working times and optimizing the results.

Both these operating systems are able to communicate through ethernet port with the other machines of the production line and, if necessary, with the manufacturer for assistance.

They can also automatically utilize various working programs which can be easily modified by the user with the touch screen.

In order to improve the instrumentation management, Imp.a.c. implements the profibus/ devicenet technology on all the machines to simplify operator access and maintenance.

The company main point is the perfectioning of the automatic systems using first class components in mechanic, pneumatic, electric, and electronic areas. The utilization of high quali-

ty components assures less maintenance, high productions and a substantial energy saving.

Imp.a.c. products are conceived in a modular way to warrant scalability according to the user necessities and to combine high efficiency to low consumption and reduced costs (TCO, Total Cost of Ownership); for these reasons they are in the highest ends of packaging lines.

PALLET LOAD

handling

and wrapping Pieri – leading Italian company in the production of wrapping and handling systems for palletised loads – has set its strategies for the year 2009 involving three key points that it has chosen as a business model. In fact in 2009 Pieri is certifying its own structure in compliance with the standard ISO 9001 (Qualities), ISO 14001 (Environment), and OHSAS 18000 (Safety). Such an investment has been thus explained by Mrs Danica Pieri: “The quality system is the result of a remarkable economic investment and inner resources. The target as usual is to elevate

Wrapping machine SilverGo (Pieri).

240 - Tecnica Molitoria International - Yearly issue 2009

evenmore the quality of our products and the satisfaction of customers”.

With the same regard for innovation and improvement, Pieri has recently begun to propose a new wrapping machine system in compliance with Atex directives. The experience made in cooperation with some important partners in the milling sector, have made possible the development of a specific know-how for the production of important wrapping systems according to Atex directives.

Another aspect on which Pieri has been concentrating is the performance; the wide product range has been recently joined by the new double arm wrapping machine mod. Silver Twin, an avant-garde solution and in line with the demands of customers for elevated outputs. The point of force of Silver Twin is identified in the two rotary arms, whose double wrapping action is able to guarantee an extraordinary performance of such machines (more than 140 pallets/hour). Particular care has been placed on the economic aspect by proposing an interesting relation price/performances and assuring minimum maintenance costs as well.

The thirty years that Pieri has been present on the market is therefore the starting point for this ambitious project of growth and renewal that the Italian company has been undertakeningh for a long time: one project towards “total quality” and full customer satisfaction.

flour & pasta packaging

Automatic FLOUR PACKING Italpack, leader in the field of automated packaging machinery, presents at Ipack-Ima the latest addition to its their wide-range of equipment for mills.

The new version of Pack 50/10: a fully-automated flour packer specifically designed and manufactured for heavy-duty deployment in both large and small flour mills. This machine, which is a natural addition to the other packing machines in the Italpack range, offers the user all of the following: flexibility (in terms of pack sizes available); capacity (both in terms of current capacity requirements and future increased capacity); full automation (only one supervisor required); health and safety (the equipment adheres to strict EU and U.S. health and safety regulations).

The Pack 50/10 automatic flour packer is destined to become one of Italpack’s best selling machines. Bakeries are now demanding that flour is supplied to them in SOS block bottom paper bags of 10 kg to 15 kg. Previously, flour was supplied from the mills in valve sacks or open mouth sacks in 25 kg to 50 kg

machinery

sacks but now due to international legislation concerning maximum weights allowed to be carried manually, more and more flour is being supplied in a weight range between 10 and 15 kg.

The problem of product leakage is also solved by packing into ready-made, SOS block-bottom paper bags. The bags are filled and then closed in a “brick pack” style which is both attractive and at the same time seals the bag in such a way that product leakage is completely non-existent.

The use of paper bags as packaging material also signifies a firm pledge on environmental issues: 100% recyclable, the paper bag is rapidly replacing plastic as the preferred packaging material of both the supplier and the consumer.

Italpack Export Sales Manager, Mark Wild explains, “We continue to listen to the market and respond to it. Packaging of foodstuffs into ready-made paper bags is growing constantly and statistics prove that paper as a packaging material is a great marketing tool. Trends and requirements change

The development of new products does not mean only developing high speed machines, it also means designing equipment for the users who need low-speed machines with finest accuracy of the bags, because of their high valued product to be packed.

Concerning the long pasta packaging, it has been designed the new horizontal packer HS20 with its new patented descending devices, its new aligned weighers in order to increase the speed and its new stripping device to avoid small pieces of product in the sealed parts.

In order to complete the whole packaging area, Ricciarelli can now supply, with another company of the group that has been working for years in this field, a large range of palletizing systems: from the simplest one called “cartesian system” to the most complex with anthropomorphic arm. All of them can be used for many packaging lines.

ance is required or if the unit is to be pre-tensioned so as to be free from clearance. The tolerance of the maintenance-free DryLin W system can be adjusted over the whole bearing surface by turning a knurled adjustment screw integrated into the side. Adjustment is in small notched steps that can be both heard and felt. Then the bearing fits the shaft correctly and can be moved linearly. If wear occurs, the system can be simply readjusted.

The system is made up of a housing consisting of several parts and a gliding film made of technical tribo-plastic. As well as the basic structure and continually tested materials, further features include a small design height, very low friction and excellent wear resistance. No maintenance, low weight and high resistance to dirt and humidity are further advantages. The clearance adjustment can also

The history of the development of the new â&#x20AC;&#x153;turnto-fitâ&#x20AC;? principle is as simple as it is logical, according to the manufacturer Igus. Some years ago, a new generation of guides was developed, the DryLin W system, the design of which allows flexible and modular construction and thus easy assembly. Now, a further beneficial factor has been added to this extremely versatile system (used for single or double rails made of hard-anodised aluminium, individual bearings or complete slides) clearance-free made-to-measure setting. This version is available in design size 10. The other design sizes (06, 16 and 20) are to follow.

New VACUUM PUMP with award-winning design At Ipack-Ima Busch presents a new rotary vane vacuum pump, which is based on the technology of the tried and trusted R 5 vac-

246 - Tecnica Molitoria International - Yearly issue 2009

uum pump, but also includes significant innovations. The new R 5 0160 E is the new generation of vacuum pumps with a vacu-

um of 0.1 mbar and has a suction capacity of 145 m3/h. The extremely constant characteristic curve over almost the whole pressure range still makes an effective suction capacity of 115 m3/h possible at a working pressure of 1 mbar. This means there is now a powerful vacuum pump available which has a high suction capacity in the working pressure range of packaging machines. In practical terms, this means: short cycle times and quick packaging.

On account of its compact dimensions, this new R 5 rotary vane vacuum pump is suitable for installation in modern chamber machines and automatic roller machines.

Ease of maintenance has been improved and consequently exhaust filters are easy to replace from the outside, without opening the pump. The innovative design makes it possible to improve efficiency and thus reduce power consumption. In the 50 Hz version, the R 5 0160 E is equipped with a 3 kW motor.

The vacuum pump design meets the hygiene requirements in accordance with DIN ISO 14159 and 1672-2. It is also possible to operate the machine as a freestanding unit directly in the processing room. As standard, the R 5 0160 E is air cooled. Water cooling is available as an option, where the pump and the motor can be cooled separately.

This new Busch vacuum pump has won the design prize â&#x20AC;&#x153;iF product design award 2008â&#x20AC;?. This prize is awarded annually to new products that stand out thanks to their unusual design. The design engineers at Busch have managed to develop a vacuum pump that is compact, powerful and economical. In addition, it meets hygiene re-

diagnostic research

The EU funded NETWORK OF EXCELLENCE MoniQA MoniQA – Monitoring Quality Assurance – a Network of Excellence (NoE) funded by the EU within the Sixth Framework Programme (Topic T5.4.5.1: Quality and safety control strategy for food) and working towards the harmonisation of analytical methods for monitoring food quality and safety in the food supply chain, celebrates its second birthday.

Started on February 1st 2007, MoniQA is coordinated by the International Association for Cereal Science and Technology (ICC) and involves a core group of 33 organisations from

248 - Tecnica Molitoria International - Yearly issue 2009

20 Countries. After two years, the NoE has expanded its activities and an Advisory Panel, providing scientific and strategic advice to the network, helped the Consortium establish links to other organisations and related research projects. As a consequence, MoniQA has grown to include, so far, more than 90 organisations from 35 countries across five continents.

Within the project there is, in fact, a possibility to become an “Associated Partner” (see http:// www.moniqa.org/index.php?id=110252) that, in principle, enables each Institution/ University/SME to benefit from several opportunities: participation in MoniQA events at reduced rates, collaboration and involvement in working groups, participation in the integration and dissemination programmes, and further future offers which may include both participation in exchange and mobility programmes, and access to MoniQA databases and other MoniQA services. One of MoniQA’s aim and expected outcome is, in fact, the building of a network of leading research institutions, industrial partners and SMEs to overcome European and worldwide fragmentation in food diagnostic research.

Besides this enlargement of the core group to a wider range of other Institutions, a lot has been

done in the first two years also within the Consortium itself. So far, six analyte specific Working Groups (WGs) have been established (Microbiological Contaminants, Mycotoxins/ Phytotoxins, Chemical Contaminants, Food Allergens, Food Authenticity, Food Additives, and Future Issues) to tackle both analytical challenges and eight horizontal issues: method performance, quality assurance and control, sampling, measurement uncertainty, legislation, economic impact, traceability and harmonisation. Moreover, two further groups were established, one for the validation of qualitative methods and another one for the management of the socio-economic impact addressing costs and benefits of quality assurance schemes and method validation at the micro-, meso- and macro-levels. In the last year, Integration Teams have also formed spontaneously by combining related competencies of various partners independent of the Work packagesâ&#x20AC;&#x2122; structures: an IT Team, consisting of database experts, a Communication Team, consisting of communication experts, a Management Team, and a Quality Assurance Team.

Working Groups and databases The establishment of the six WGs is the natural outcome of the fact that MoniQA was funded as an answer to globalisation, but mostly as a need to ensure a high quality and safety of the foods and food products that are being traded around the world. In the last decades, the whole food supply chain has become a complex system of crossroads between suppliers and producers, retailers and ultimately consumers; therefore, at each crossing point some sort of documented quality control, which must be acceptable to the supplying and the receiving parties, as well as to regulatory authorities and control institutions, is required. MoniQA aims at finding efficient

solutions to these issues that may be acceptable to all parties involved in the food chain by means of the above-mentioned WGs. These latter are seeking to establish mechanisms that enable consumers and international trade to benefit from high quality and safe food which is tested by reliable and internationally accepted methods.

MoniQA is also meant to be and further become a reply to the fragmentation of research and standardisation, to the limited validity of validation certificates for rapid methods, alternative methods and test kits, to the lack of appropriate validation protocols for new and rapid methods, and to a lack of confidence in the competence and reliability of these methods. In this second year, WGs have thus worked at the collection of validation protocols and criteria used for method validation by national and international organisations. They have identified reference methods and reference materials used for validation/ standardisation of new and rapid quantitative, semi-quantitative and qualitative screening methods and have also worked at the development of strategies and guidelines for the harmonisation of risk assessment and the standardisation of analytical methods and technologies in food safety and quality. Participants to each WG have jointly prepared a thematic position paper that will be the basis for the elaboration of the first draft of harmonisation strategies and guidelines.

MoniQA is playing an important role in integrating European and worldwide food quality and safety research by creating a virtual laboratory for research, training and mobility programmes. It is, in fact, actively promoting sharing of data and knowledge, of equipments and materials as well as of personnel through the creation of a platform for food quality and safety researchers. For this purpose, a database has

Tecnica Molitoria International - Yearly issue 2009 - 249

diagnostic research

been created as an inventory of equipments, facilities, analytes and methods used within the Consortium. Moreover, another database is being completed with information about legal constraints and limiting factors to researchers’ mobility and to any possible sharing of research infrastructures within the Consortium.

Mobility and Training Anticipating the 7th Framework Programme, MoniQA has also widely worked at “People”.

Education and training are integral parts of the MoniQA Network of Excellence and a mobility programme to promote the exchange of personnel, including the setting up of PhD student bursaries, was established. Currently, MoniQA partners can benefit of two types of exchange: either “exchange” or “visit”. When two MoniQA partners agree that a PhD student, postdoctoral researcher or senior staff member visit one-another, this is a genuine “exchange” of personnel, whereas a “visit” is the case when a PhD student, post doctoral researcher or senior staff member visits a partner for a specific goal, e.g. exchange of information or acquisition of skills. MoniQA has extensively worked on visits, as they are the means by which a researcher can get new skills, have access to new or different methods, use new or different equipments, make joint analyses of samples in a standard way, test approaches or kits, and work on a task related to a deliverable.

In the second year, MoniQA offered concrete training opportunities, organising “MoniQA Food Scientist Trainings” (MoniQA FSTs) which deal with research management skills and impart technical knowledge of relevance to food scientists. Last December 2008, for example, a three days Food Scientist Training (FST) on “Food safety and analytical challenges in the cereal based food chain” was organised and held at the “Budapest University of Technolo-

250 - Tecnica Molitoria International - Yearly issue 2009

gy and Economics”, Hungary. Updated overviews of the European situation, regulation and the analytical solutions for all those components which cause the most frequent food safety hazards in the cereal supply chain were presented. In addition to the theoretical lectures, laboratory demonstration of the available rapid methods were organised. In October, the Chinese Cereals and Oils Association (CCOA) in Nanjing (China) organised another FST where topics like the application of modern methods (ELISA) in food safety and the developments of food safety systems in China were offered. Other FSTs were organised in Vienna, Rome, and Prague and all participants had the opportunity to gain new knowledge on a wide range of topics which are tackled within the MoniQA Network. So far, upcoming MoniQA FSTs are planned to be held next March, first in Hungary and then in Christchurch (New Zealand), and another one in April at the Hacettepe University, Ankara (Turkey).

Spreading of Excellence But MoniQA is not only personnel exchange and merging of infrastructures, harmonisation and standardisation of analytical methods, development of databases for food safety hazards, evaluation of the socio-economic impact. MoniQA is also “Spreading of Excellence”. Spreading of Excellence activities include events, but also other channels and instruments, such as a website, newsletters, posters, publication of scientific papers.

Meetings represent an integral part of any network and throughout this second year, MoniQA has organised several work packages and working groups meetings, besides an International Conference. Last October, 2008, the 1st International MoniQA Conference brought together a global audience of more than 200 food safety scientists, socio-econo-

mists, regulators, industry and trade representatives as well as media correspondents. The participants had the opportunity to discuss the most recent challenges in avoiding and controlling unwanted substances in the food production chain as well as to obtain information on the newest developments and innovations in rapid and reliable analysis of food contaminants. Speakers included representatives from the Food and Agriculture Organization of the United Nations (FAO) and the European Commission (EC), as well as experts on food safety issues that were divided into seven sessions based on the MoniQA working groups. Other features were poster presentations and a Best Poster Award, as well as a plenary lecture on “Food Quality/Safety Control: FP7 Research Challenges”. In addition, two side events, a MoniQA Food Scientist Training (MFST) workshop on science communication and an international expert workshop on cost-benefit of food safety regulations were held.

On the occasion of the 1st International Conference, MoniQA proved to be very sensitive to the last “hot issues” in the field of food safety and quality. It devoted, in fact, a share of its resources to emerging and unforeseen food safety issues like melamine. Researchers and scientists discussed and reacted quickly and comprehensively to the emerging food safety issue of melamine in Chinese milk with presentations on the current state-of-play by two researchers from Sichuan University, and later a fact sheet on “melamine” was prepared and distributed. Also the “Irish Pork and Dioxins issue” was widely discussed.

Within the dissemination activity, a first newsletter was also produced for external stakeholders in order to highlight the project achievements by now: MoniQA work on mobility and training issues have been showcased and activities for the different MoniQA stakeholder au-

diences were outlined. Two fact-sheets, on food safety and quality and on melamine, featured the project results in accessible format.

It is worth highlighting that MoniQA, in cooperation with ICC, is also issuing a new international journal titled “Quality Assurance and Safety of Crops & Foods” published by Wiley-Blackwell, that will issue peer-reviewed, scientific primary research papers and review papers related, amongst other topics, to food and feed quality and safety. This journal aims at publishing the work and activities of the ICC technical working groups and of MoniQA working groups, at informing about relevant meetings and training opportunities, educational programmes and association news, as well as at informing about new regulations, political decisions and agreements affecting global trade of cereals and other crops, foods and feeds. The first issue, March 2009, publishes articles by the different WGs. The future It can be concluded that the MoniQA net has fully achieved its objectives and technical goals for the first two years and now that it is entering into its third year of activities, new progresses are expected: durable integration, mobility programmes, guidelines for validation and presentation of results, databases for food safety and quality analytical methods, better regulations in the field of food quality and safety, other training and dissemination events. Moreover, MoniQA is expected to develop services and products which will be marketed and thus will support the sustainability of the network and its outputs beyond the EC funding.

events Ipack-Ima 2009: the world expo for agro-food PROCESSING, HANDLING, PACKAGING Ipack-Ima plans new records for 2009 and gives a primary role to integration: revolving around packaging as a common element, the exhibition is the pivotal point for food processing technology.

Held from March 24th to 28th 2009 at Fiera Milano in Rho-Pero (Milan, Italy), it has an even stronger international character than the 2006 edition – where a visitor out of 4 came from outside of Italy from a total of 124 Countries – and puts the spotlight on integration between the different aspects of the production chain on display.

The outstanding 2009 edition features the joint staging of Ipack-Ima, Grafitalia, Converflex and Plast exhibitions. Ipack-Ima has strong roots in the industry of packaging machinery and materials, which takes up 25% of the exhibition. The integration in progress in the different production chains involves packing and packaging and the related technology, raw materials, processing technology, packaging materials, and logistics. Some areas are under the spotlight such as Labeltrack focusing on product tracking technology.

Grain Based Food represents an outstanding area within the exhibition, for which IpackIma has earned worldwide renown. The

252 - Tecnica Molitoria International - Yearly issue 2009

2009 edition is the place to be for all professionals working in the pasta, bread, pizza, and snack industry, also featuring the best of the Italian milling industry thanks to the partnership with Italmopa (Italian Milling Industry Association).

Ipack-Ima international prestige is highlighted

by FAO decision to hold the international congress “More Technology, Safety and Quality, Less Hunger” on the role of food processing and packaging technology in the fight against world hunger during the exhibition. This decision gives Ipack-Ima a primary international role at the heart of technological evolution dedicated to the food industry, particularly for the processing and packaging of grainbased food and milling products, which are vital to finding a solution to the world-spread food emergency.

The congress by FAO also reinforces the connection between the main themes of IpackIma and the Expo, once World’s Fair, “Feeding the planet, Energy for Life” which will be staged in 2015 at Fiera Milano.

The worldwide demand for the cut-edge technology on display shows in the figures: the 2006 edition featured the participation of 1,500 exhibitors and around 50,000 visitors, 26% of whom coming from interna-

events

tional markets. 56% of visitors, according to surveys carried out by an independent research firm, held high corporate roles (owners, top managers), and 26% were technicians. 85% had decision-making power, 42% of whom deciding independently and

43% participating actively in the decisionmaking process.
