$MART THINKING $6.2M OFF REDEVELOPMENT COSTS, MILLIONS OF DOLLARS PER YEAR OFF ENERGY AND CARBON LIABILITY COSTS AND OVER ONE THIRD OFF EMISSIONS.

CARBON EMISSIONS

STEAM AJ Bush & Sons have long been one of Australiaâ&#x20AC;&#x2122;s largest rendering operations. AJ Bush selected WILEY to design and build their facility in Beaudesert, Qld in late 1992, and to rebuild the facility after a fire in 2001. We are now working together on a process focussed project to improve production efficiency and cut energy cost throughout the AJ Bush operation to reduce its direct carbon liability. Wiley is helping AJ Bush to turn an inconvenient waste product into a lucrative energy recovery system. This will mean a huge annual energy saving, a new stream of export revenue and has secured a $6.2M redevelopment grant from the Clean Technology Food and Foundries Investment Program. An innovative initiative to cap and recover unexploited biogas from their Beaudesert rendering ponds will save millions on annual energy and carbon costs, reduce annual emissions by over a third and reduce the intensity of remaining emissions by a further 64%. Ecofficiency means improved efficiency, productivity and profit with reduced impact on our environment. Thatâ&#x20AC;&#x2122;s creating a better future!

Crumbs from my table

Like, I am sure, the rest of the food industry, I found the recent horsemeat substitution scandal in Europe fascinating. It was made more interesting in many ways because, for once, it wasn’t a food safety crisis and consumers were not becoming sick. They were just being fed horse instead of beef. Mind you, 4.5 million ready meals containing horse instead of beef are a lot of ready meals and a lot of people unknowingly eating said horse. As the scandal developed I was interested to note that the initial horse grew into ‘horse-like animals’ including donkeys, asses … However, when South Africa did some internal testing I thought they were really showing off when their contamination species included water buffalo and goat. What has slipped under the radar is contamination with pork. In the opening salvos of the crisis the Irish also reported contamination with undeclared pork products. Contrary to the horse substitution, contamination with pork does affect some consumers for whom pork is a forbidden food. Had this contamination received the same attention as the more mainstream salacious horsemeat story it would have been interesting to watch consumer reaction. However, it all really gets back to the same thing - consumers have a right to labelling honesty. The information on the label should allow the consumer to make their own choices and be confident that they are purchasing what they think they are purchasing. The other issue that is currently interesting me is the protein debates. Getting crude protein content results by multiplying up nitrogen assays leaves manufacturers open to scandals like the melamine substitution in the infant milk formulas in China. But even accurate protein content of a food is not enough to determine the nutritional value of the food. The availability of the protein is affected by its digestability - some proteins are simply harder to digest and so pass straight through the consumer and add the balance of their nutritive load to the sewage farm. Another limiting factor of the benefit of the protein is the blend of amino acids it contains. It doesn’t matter how much protein a consumer eats - if the protein does not contain sufficient quantities of the nine essential amino acids that humans cannot synthesise in vivo the person will be unable to synthesise the proteins they need and so will be effectively malnourished. I think we will see more debate on this topic between the dairy and soy industries for a while yet.

European food and beverage hygiene company Calvatis is launching its Calgonit brand in Australia, and has ambitious plans to “shake up” the food and beverage industry. Calvatis Australia General Manager Christopher Ratcliffe said that the company has been watching the food hygiene space in Australia and believes that there is a gap in the market for a new player dedicated to working with food and beverage companies to provide tailored hygiene solutions. “We’ve set out an ambitious strategy to shake up the food hygiene industry through innovation and exceptional customer service. We aim to work with the food and beverage manufacturing industry to solve problems on a case-by-case basis; the one-size-fits-all cleaning mentality is long outdated and we aim to change this,” Ratcliffe said. “We believe there is significant opportunity to leverage the full power of Calvatis’ technology portfolio, and redefine service in the Australian food and beverage hygiene industry.” The company operates in more than 70 countries with services focused on adding value for mid-sized food and beverage manufacturers. Calvatis Australia plans to rollout its selection of detergents and sanitisers throughout Australia and expand its range of German-designed cleaning equipment.

Food safety for fresh produce industry A new website dedicated to all aspects of food safety in the fresh produce industry has been launched. The Fresh Produce Safety - Australia & New Zealand (FPS) website was established as part of a major project to identify priorities for fresh produce safety research and to raise awareness of the challenges and importance of enhancing current safety practices. The FPS website, www.freshproducesafety-anz.com, was launched by the University of Sydney’s Faculty of Agriculture and Environment and PMA Australia-New Zealand, the region’s leading fresh produce trade association. The FPS website focuses on three critical objectives: 1. To plan how the fresh produce industry will handle major food safety outbreaks in the region, particularly in crisis mitigation and management, and consumer communication. 2. To identify research needs that are specific to the Australian and New Zealand fresh produce industry and to develop local or international collaborative partnerships in research, outreach and education to address these needs. 3. To translate relevant research outcomes from the Center for Produce Safety at the University of CaliforniaDavis for application in the Australasian fresh produce industries. “The 2006 spinach crisis in the US and the European sprout problems of 2011 demonstrate the importance of our industry working together from paddock to plate to ensure continued fresh food safety in Australia and New Zealand,” said Associate Professor Robyn McConchie, head of the Plant and Food Sciences department at the University of Sydney. “We anticipate developing a research model where we will be utilising existing research and information, as well as bringing together international experts, representatives of government, industry associations, growers, packers and processors, wholesalers and retailers, food safety trainers and practitioners, all with a focus on filling the knowledge gaps on produce food safety in Australia and New Zealand, and protecting and enhancing food quality and safety in fresh produce,” McConchie said. A Food Safety Taskforce initiated by PMA Australia-New Zealand and comprising representatives from all sectors of the supply chain has also been appointed to assist in the project and work collaboratively with industry to facilitate communication and outreach. “An outbreak of foodborne illness can be devastating, not only for those directly affected, but for an entire industry,” said Fabian Carniel, Chair of the Food Safety Taskforce and Joint CEO of Mulgowie Farms. “As an industry, we have a responsibility to live up to the trust placed in us every day by consumers, by ensuring the safety and traceability of our fresh produce.” The FPS project used voluntary funds from both organisations, which was matched by the Australian Government through Horticulture Australia Limited (HAL).

Hygiene company to shake up food and bev industry

Private label campaigns reducing choice, says AFGC Major supermarkets are reducing their overall product range as they aggressively promote their home brand products, the Australian Food and Grocery Council (AFGC) claims. According to AFGC CEO Gary Dawson, research released by Coles reveals the extent of the fall in product choices on offer to consumers. The research, conducted by Deloitte Access Economics, showed that Coles’ product range dropped by 11% from mid-2010 to mid-2012, from 62,000 to 55,000 products. “A loss of 7000 products from a supermarket’s overall offering is a significant reduction in the range of choices available to consumers,” Dawson said. “These figures confirm what shoppers report anecdotally - that they often can’t find their favourite products on the shelves any more when they go to the major supermarkets.” Dawson said Coles’ latest campaign to promote its private label products indicates that this trend will continue. “This is a classic Trojan horse tactic - disguising a longer run loss of choice for consumers,” Dawson said. “And as the range of choices drops, so does competition, raising the risk that in the longer run, the major supermarkets will have even more market power. “The thousands of suppliers that make up Australia’s $110 billion per annum food and grocery manufacturing industry rely heavily on the major supermarkets to get their products to consumers. “Consumers who find their favourite products have disappeared from the supermarket shelves should raise it with the store manager and make their voices heard.”

US appetite for high-protein products grows

High-protein foods are taking off in America, according to new research from Mintel. Introductions of foods and drinks making a high-protein claim are almost three times higher in the US than anywhere else in the world, accounting for 19% of global new product launches in 2012. The US is the biggest market for high-protein products by a significant margin: India and the UK follow with 9% and 7% respectively of new food and drink launches with high-protein claims in 2012. “Protein awareness is higher and more sought after by US consumers than elsewhere in the world and the opportunity exists for value brands to add cost-effective protein to products to entice a larger consumer segment,” said Nirvana Chapman, global food science trend analyst for Mintel. “Americans are looking for protein to aid in satiety, weight management and to boost muscle recovery and build muscle after a work-out, making protein appeal to a broad audience in a great number of usage occasions.” High protein doesn’t necessarily mean meat based, according to Mintel’s research. The demand for high-protein products is also coming from consumers who are avoiding animal sources of protein for either health, environmental or ethical reasons. Products launched in the US with both a high-protein vegan claim have shown a steady increase since 2008, posting 54% growth in the past five years to 2012. Renowned for keeping you full for longer, high-protein foods are also tapping into the wider satiety trend. When selecting food products, 87% of US consumers indicated satiety is an important attribute for them. “A ‘satiety index’ (SI) is often used to measure the hunger-fighting power of certain foods,” Chapman said. “Foods with a high-SI leave people more satisfied after eating and ensure that they are likely to eat less for hours after. “Protein in particular has been shown to have a positive effect on subjective satiety, with whey protein in particular having demonstrated a functional role in weight management and satiety. High-satiety products are likely to continue to grow, with meals and soups integrating high-protein content being the ideal categories for growth. “In the weight-management industry, there is an upward trend towards products that combine whey protein, peptides and calcium for weight loss. Specifically, the high-protein trend is growing worldwide, evidenced by countries with high-protein-claim products being launched, as well as European examples of consumers seeking high-protein products. Manufacturers can capitalise on this opportunity to educate and entice consumers with protein to meet various needs,” Chapman concluded.

No horsemeat on the menu for Australia Australians can rest assured that there is no horse in their hamburgers, a Charles Sturt University (CSU) academic has said. According to Dr Shevahn Telfser, a livestock lecturer from CSU’s School of Agricultural and Wine Sciences, the risk of horse meat making its way into beef products in Australia is very small. “As a general rule, horse meat cannot enter our supply chain because Australia imports very little red meat and there are strict measures in place to ensure there is no mixing of processed products,” Telfser said. “This protects the industry to a large extent from the possibility of horsemeat accidentally entering the human food supply.” While it’s unlikely that we’re unknowingly dining on equine meat, Telfser said around 26,000 tonnes of Australian horse meat

March/April 2013

is exported for human consumption each year, mostly bound for European markets. “It is the most-commonly eaten meat in some European countries and more than 700,000 tonnes of horsemeat enters the human food chain each year,” Telfser said. But don’t expect to see Australian farmers jumping on the horsemeat bandwagon, Telfser said. “Horses require complex diets and are not as efficient as cows in converting the food they consume into meat,” Telfser said. “There is also a social stigma in Australia that horses fall into the companion animal bracket rather than being production animals, so horsemeat trade tends to be largely an opportunity trade which relies on a supply of surplus or cull animals from more traditional horse industries.”

Save energy through lighting management ©iStockphoto.com/ pagadesign

With the continued rise in energy costs impacting businesses across Australia, investing in energy efficiency makes more sense than ever. Energy is a significant controllable cost for every manufacturing business and the more energy you save in your business, the more profitable you can be.

nergy-efficient lighting is an obvious starting point for businesses looking to reduce energy consumption and demand across their business. Return on investment can be attractive, energy savings can be significant and lighting, while a critical ‘hygiene’ factor is a reliable and easily quantifiable investment. Since the ’90s, there has been a slow uptake in increasing lighting energy efficiency which has been driven by environmental awareness and the opportunity to improve the lighting experience. There is now a sense of urgency for businesses to implement lighting solutions due to a rapid increase in electricity rates. Ed Hanna, director of sustainability at Energy Action, said, “Energy-efficient lighting is increasingly being sold as a commodity product, but quite rightly, the lighting experience is a sensitive issue for many buyers. “Industrial and manufacturing plants historically have been illuminated by mercury vapour and metal halide lights which, by comparison to modern alternatives, are an expensive option to operate when it comes to lighting factory floors. Lighting is an essential need for all businesses and any decreases in quality, reliability, safety or the look and feel of lighting can have a significant bearing on core operations. In recent years, the development of induction and LED lighting can now provide a real opportunity for businesses to move towards a more efficient lighting strategy.” Energy Action offers five tips for the manufacturing industry looking to retrofit energy-efficient lighting: 1. Examine your options before you commit to a technology. Lighting and control technologies are dynamic and are evolving quickly. Assessing the market can be time-consuming and complex. Think about what is best for your company in the long term.

March/April 2013

2. Consider the needs of all stakeholders. Lighting levels, beam angles and colours will determine your stakeholders’ lighting experience. Will the result comply with Australian standards? Will they comply with your stakeholders’ expectations? Make sure that you are aware that interior lighting for retail and commercial purposes comes in a range of light levels, colour spectrums and output shapes for different purposes. 3. Invest in lighting controls. Occupancy sensors and daylight sensors can lower your energy bills, particularly in low traffic areas such as stairwells, meeting rooms, utility rooms and car parks. Intuitive and locally controlled lights are becoming increasingly cost effective for these environments. Use flexible lighting solutions in areas that are not constantly in use, eg, shift work. Most current energy-efficient alternatives allow you to dim or turn off areas when not in use, without worrying about long warm-up times. 4. Make informed decisions when choosing suppliers. Choose your suppliers and installers on recommendation referrals, experience and reputation, as well as price. Always check your warranties, lead times and service expectations before you place an order. If you can’t find a lighting salesperson you trust, get a lighting market consultant to guide you. 5. Have light intensity that suits each individual work area’s needs. Optimising energy efficiency means delivering the right amount of light to the workspace. You can do this through the right combination of fittings, lamps and controls. Taking all of these into consideration will ensure that you lighting strategy will successfully reduce energy use, lower energy bills and reduce the carbon intensity of the business.

Crate results for citrus growers

BULK

Fruit growers invest blood, sweat and tears (sometimes literally) into their products, selecting the right variety, then protecting and nurturing trees for years before they yield a commercial crop. They are both a grower’s livelihood and passion, and the last thing the grower wants is to see fruit damaged or the quality compromised as it travels through the supply chain. Growers are also a pragmatic bunch, so when citrus grower and market agent Chris Deveney from Favco says that his first choice for shipping oranges and mandarins through the supply chain is a CHEP crate, there has to be a practical reason why. “The crates look after the product better,” Deveney says. “They travel better, get better airflow through the product which maintains the cool chain better and therefore the product quality is better.

“Also there’s no sag. If cardboard gets wet for any reason you get compression in the fruit. As cartons are put on trucks they tend to compress together. You don’t get that with crates. The crates transport beautifully through the supply chain and they don’t damage fruit.” Favco is numbered among the growers that are going back to using CHEP crates for oranges after a brief sojourn into cardboard cartons. As soon as it was known that oranges would again be accepted in crates, Favco switched back. “We never stopped using them for mandarins,” Deveney said. Mandarins are less robust than oranges, and require a tightly controlled cool chain to maintain quality. However, even the robust navel copped a beating in cardboard compared to crates, with damage rates increasing by 50% on large fruit. “We were one of the first farms using crates when they were introduced in 2000, particularly for mandarins,” Deveney said. “They improved our overall performance, with interstate arrivals turning up and we’ve been a fan of them ever since.” Favco has farms in Mundubbera and Mareeba in North Queensland and also sources citrus from no less than 150 growers across Australia including citrus from the Riverina, Riverland and Mildura regions. In addition to crates, Favco also uses CHEP bins for picking and CHEP pallets when transporting loads. CHEP Australia Contact info and more items like this at wf.net.au/T045

Sanitary tilt-down flexible screw conveyor Flexicon has released a Sanitary Tilt-Down Flexible Screw Conveyor on a castor-mounted frame that can be manoeuvred through narrow aisles and around corners. With the hopper, support boom and conveyor assembly tilted down, the unit fits through standard doorways and orients the conveyor tube horizontally, allowing the flexible screw to be removed easily for thorough cleaning and inspection.

BULK

The conveyorâ&#x20AC;&#x2122;s surge hopper, which is configured for dust-tight connection to the outlet of upstream equipment, includes an air displacement vent with cartridge filter that is equipped with a reverse pulse cleaning system that dislodges accumulated dust with short bursts of compressed air, returning the dust to the hopper on a timed cycle, maintaining operating efficiency. Material flows through the hopper into an adapter that charges the conveyor. The flexible screw is driven only at the discharge end and does not require any bearings or seals within the product contact area. As the flexible screw rotates in the material, it self-centres within the tube, providing ample clearance between the screw and tube wall to eliminate or minimise grinding. The conveyor transports bulk ingredients ranging from submicron powders to large pellets, while the gentle rolling action of material being conveyed prevents the separation of blends. The enclosed tube prevents product and plant contamination and permits thorough washdown. Removing a clean-out cap at the intake end of the conveyor tube allows rapid emptying and flushing of the tube as well as disassembly and washdown of components. The rugged inner screw is the only moving part contacting material, resulting in reduced maintenance and increased reliability. A broad range of specialised screws is available to handle free- and non-free-flowing bulk materials, including products that pack, cake, smear, seize, plug or fluidise. The mobile conveyor frame is constructed of stainless steel (shown) or in carbon steel with durable industrial coatings, and can be finished to sanitary or industrial standards.

Compressed air energy audit service

BULK

The Energy Efficiency Services (EES) division of Compressed Air and Power Solutions (CAPS) has expanded its range of services and increased the number of staff available to carry out compressed air energy audits. With compressed air being responsible for 10 to 15% of industrial electricity use, an air audit can reveal opportunities to reduce energy consumption and overall business costs, the company says. While compressed air is an important part of most manufacturing and industrial processes, many systems operate inefficiently with old technology or ineffective controls. Large volumes of air are wasted through leaks, inappropriate usage and other artificial demands such as over-pressurisation. Audits regularly show that less than half of the compressed air produced is used for actual productive activities. With the right advice and experience it is possible for companies to achieve savings, CAPS says. Making use of the audit expertise of a consultant to develop commercially viable and operationally feasible solutions will help companies achieve their goals. Sustainability continues to be a major goal of business across most industry sectors. A key factor in this is the minimisation of energy consumption and waste of resources. EES has designed a software suite and air audit hardware package, which it has teamed with extensive training and development of its engineers and technicians to undertake audits. To assist in driving implementable recommendations, additional industry experts have also been employed to conduct the air audits, provide analysis and provide independent reports.

to a minimum, which is achieved by pre-stretching the film by more than 400%. On a pallet measuring 800 x 1200 x 1500 mm, using nine layers of film and a standard film reel of 500 mm wide x 23 Âľm, only 96 g of film is used. The patented Syncro device enables clamping, cutting and welding of the film while in motion, which saves considerable time as the film is cut and sealed while it is being removed from the wrapping area. As the pallet/load is static, the stability and integrity of the stack is maintained during the high-speed wrapping process.

The perils of ignoring lubrication in the food industry PROCESSING Aaron Crichton* © www.sxc.hu/nkzs

If a food manufacturer was to ask me what the greatest risk that lubricants could have on my business, my answer would be the potential for food and beverage to reach the market place containing undetected nonfood-grade lubricant.While there are other negative impacts lubricant can pose on a food manufacturer this is clearly the most substantial and potentially damaging.

What role do lubricants play? Every food plant requires lubrication. Various greases and oils lubricate processing equipment, allowing moving parts to function as designed and hopefully ensuring thousands of hours of trouble-free operation. However, unique to food manufacturer and other clean industries are the potentially damaging consequences from lubricants inadvertently finding their way into food and beverages which reach the marketplace and an unsuspecting consumer.

Costly consequences Now, in all fairness, lubricant-related food recalls are quite rare and I suggest there are very few in the food industry who could remember the last time a food manufacturer fell victim to a non-food-grade lubricant contamination or recalled their product from the marketplace. However, it has happened and to some of the largest food and beverage companies on the planet. Below are some documented case histories where the unforeseeable has occurred. Sliced turkey meat: A US firm recalled 36,000 kg of sliced turkey inadvertently exposed to a non-food-grade lubricant during processing. The problem was discovered by the consumer complaint analysis of complaints and a follow-up investigation where consumers complained of off-colour, off-odour turkey while some consumers reported intestinal discomfort. Source: www.fsis.usda.gov/OA/recalls/rnrfiles/rnr038Smoked boneless hams: A US firm recalled 222,658 kg of smoked ham after some

were contaminated with gear lubricants. Several customers reported a “bad taste” and “burning” in the throat for up to three hours after eating the ham. Source: www.fsis.usda.gov/OA/recalls/rnrfiles/rnr008Cans of baby food: A mother in the UK alerted the environmental officer, claiming that a tin of baby food tin “smelled of tar”. Upon further investigation it was found that the tin contained mineral-oil lubricant possibly from a machine during the manufacturing process or the can-manufacturing process. Source: The Sentinel, 1 September 2000. Now I can only speculate as to how non-food-grade lubricants came be used in areas that would appear to be critical control points where food-grade lubricants should have been used. Did these companies have any policy on lubrication usage, had a risk assessment been conducted, or was it simply human error? I guess we may never know. An interesting point I like to consider is: would the alarm have been raised by the consumer if food-grade lubricants had been used, even though our undeniable objective is to ensure that no lubricants come in contact with our food product?

How often could this happen? Recalls caused by lubricant contamination are quite rare; however I have strong reason to believe that minor instances of contamination go on unnoticed where food manufacturers have not undertaken due diligence and identified their lubricant hazards. Simply put: how do you detect the risk if you don’t identify the hazard?

www.foodprocessing.com.au

March/April 2013

Is my business at risk? Depending on the type of manufacturing process, some companies are more exposed to the potential of lubricants contamination than others. Ask yourself the question: has our business adequately identified the locations within our plant where food contact can occur and, if so, can we detect an incident where lubricant comes into contact with food before it reaches the market place? If the answer is ‘no’ then your business may have some risk, however minor, of an undetected lubricant contamination.

PROCESSING

Key indicators From personal experience, I have found the companies I would most consider at risk from lubricant contamination often display several defining characteristics. These characteristics are my key indicators which I use when visiting food manufacturers to determine the risk that lubricants may pose to their business and the required solutions to address these risks. • Policy - The absence of a company policy for lubrication - determining the type of lubricants accepted for site use. • Hazard analysis - The absence of a documented lubricant hazard analysis within the food safety program. • Documentation - A food manufacturer’s inability to provide sufficient documentation to determine where lubricants are required for use. • Management - Difficulty managing lubricant usage and the introduction of non-approved lubricants. • Housekeeping - Poor lubricants storage and handling practices, suggesting that lubricant contamination, misapplication and operator confusion is a possible occurrence. Now I don’t suggest that food manufacturers who have not addressed my key indicators are unknowingly contaminating their product, however, they may be considerably more exposed to the risks of lubrication contamination if they haven’t.

The underlying message is that some of the largest companies on the planet have been the victim of an undetected non-food-grade lubricant contamination reaching the consumer. Dedicate time to your companies’ lubrication requirements, ensuring the hazards are identified and monitored before the undetectable happens.

What can you do? Develop a comprehensive report containing your plant‘s total lubrication requirements with particular focus on the obvious lubricant applications which are above or adjacent to food production where spills, leaks or human error may result in food contact. This information will determine your policy which is, basically: will I use only food-grade lubricants or a combination of food-grade and non-food grade? Technological advances of food grade lubricants is such that they can be used in almost every application without compromising machine life or production so total food-grade implementation within food processing areas should seriously be considered. Your report will also determine a finite number of lubricants required for your plant to operate efficiently which, in addition, will allow you to develop the most appropriate lubricants’ storage facilities to effectively manage the use and transportation of lubricants within your processing facilities. Document and communicate your lubricants policy ensuring all staff are aware of safe manufacturing procedures. *Aaron Crichton is Managing Director at Superior Lubricants Pty Ltd (www.superiorlubricants.com.au).

Baiting station for controlling rodents and crawling insects BaitSafe offers a HACCP-certified alternative to conventional methods of traditional surface baiting. BaitSafe is certified throughout the food industry for use in controlling rodents and crawling insects. The baiting station can be installed into walls, ceilings, flatroofed areas, eaves and floors, between floors, cupboard bottoms and other areas, allowing pest controllers to inspect, monitor and/or place bait directly into areas where pests live and breed. In contrast to traditional bait stations, BaitSafe is not exposed to the public, therefore eliminating the risk to staff, children and pets. Once installed, pests living in the walls or ceilings have easy access to the bait without coming into contact with humans. BaitSafe is easy to monitor once it has been installed. Using the key, pest controllers can quickly access the bait, check for evidence of pests and replenish the bait supply if needed. Unlike conventional baiting methods, no ladder is required to monitor BaitSafe units that are installed in ceilings. Instead, pest controllers can screw a standard extension or paint pole into the key to open the unit from floor level, therefore reducing service time, simplifying the maintenance process and removing issues associated with working at height.

PROCESSING

Filling your biscuit Bakery filling creams for sandwich biscuits (also known as sandwich creams) pose numerous process challenges including dispersion of the high sugar content (50-70% fine sugar), the time to mechanical stability and the high pressure and torque required to handle the product. Additionally, health concerns, consumer demands and legislation have led to the reduction or removal of trans fatty acids and, indeed, reduction in the percentage of saturated fatty acids from these products. This has left many producers with the challenge of handling a recipe that has a slower crystallisation speed which results in a change in the vital consistency of the product.

March/April 2013

www.foodprocessing.com.au

of the recipe, temperature and time. The firm, poor-flowing properties of a cookie cream require an SSHE which can handle the associated high pressure and high motor shaft torque. To avoid the sandwich cream from setting in the line and creating a blockage, a direct connection to the filling machine is desirable and improves operational reliability.

Reducing saturated and trans fatty acids The requirement to reduce or remove saturated and trans fatty acids from recipes have changed the way the cookie cream recipes react. These healthier products are based on the use of oil blends which mainly contain palm oil, palm stearin and, sometimes, palm kernel oil. The slower crystallisation speed of palm oil creates filling creams with softer consistency. This can cause problems with the stability of the final cookie and variances in the depth of the cookies - which in turn creates issues with packaging. To compensate for the recipe change and the use of palm oil, the filling cream can be cooled to a lower temperature (16-17°C instead of the traditional 20-22°C). This achieves the required consistency but does require a machine to provide the increased cooling capacity and handle the high pressure generated - such as the Gerstenberg Schröder Kombinator SSHEs from SPX. Tests have shown that the lower temperature level can be obtained and capacities maintained

through the use of a bigger heat transfer surface. Other minor adjustments, such as less mechanical treatment to avoid de-oiling of the product, have further been proven to optimise the filling cream texture. In this process it is important to obtain a homogenous distribution without destroying the structure of the crystallised oils. Creams with low trans fatty acids are more sensitive to processing changes than traditional blends and tend to get too soft if gas is distributed into the mixture at the end of the process with a mixing unit. Having the right configuration of SSHE means that the gas can be added at the crystallisation stage, a high homogenisation is achieved and the structure of the crystallised oils can be protected - keeping the desired consistency of the filling cream for its application.

A completely closed system provides assurance of a more hygienic solution but can also bring other significant advantages in bakery applications. For example, the equipment is jacketed or insulated to keep process temperatures consistent - a critical factor for reproducible product quality. As ambient temperatures vary within the factory setting from summer through to winter, such insulation keeps the cream at the same temperature when it reaches the filling machine. A closed system further helps prevent the incorporation of air, reduces residence time and can operate continuously to produce higher capacities. The SPX Gerstenberg Schröder brand has vast experience in the processes used in the production of bakery creams and has worked closely with its customers to resolve the issues faced, particularly in the production of sandwich creams with low trans fatty acids. It has comprehensive test facilities for users to check recipes and processes before installation for full production. It also offers pilot plants which can be rented for testing directly at the production site. SPX has proven, tangible solutions for customers facing problems adapting processes to avoid trans fatty acids and its machinery delivers real customer benefits in efficiency, reliability and cost savings.

high-quality cream will be well homogenised, have a good taste and mouthfeel and have the right viscosity at temperature to provide the required mechanical stability needed by the final product. These thick, fast-setting products require specific process features to ensure efficient, high-quality production. They need to be produced near the filling station to ensure the correct consistency for the application and up to 40% gas injection (usually nitrogen) may also be required within the process. To make the cream, sugar is dispersed into a mixture of melting fats and then quickly cooled on a scraped surface heat exchanger (SSHE). In order for the cream to sit correctly on the cookie and hold the layers together, the crystallisation of the fat is controlled so that it occurs immediately after the filling process. This control is a function

Easy to sanitise -

the best way to ensure cleanliness

The highest level of sophistication in production processes is required for the manufacture of confectionery products. In particular, manufacturers assign the highest priority to hygienic design for open processes - processes where the product comes into contact with the production equipment. Machines designed in a way that improves process safety and product shelf life are given preference.

ell-thought-out plant design should ensure that stainless steel housings provide maximum hygiene, ‘dead zones’ are avoided and the entry of dust and moisture prevented. The sealing material should guarantee a level of protection up to IP66 and the surface of the housing should have roughness of less than 0.8 µm and be finely brushed in the drip direction - the best conditions for the safe draining-off of liquids.

Certifying the highest hygienic standards But as simple and self-evident as it sounds, hygienic design is not easy to achieve in practice. The European Hygienic Engineering & Design Group (EHEDG) provides assistance in this area to confectionery producers. The Group defines criteria for easy-to-sanitise design in a large number of guidelines and certifies components that meet the standards. The certificate is considered a quality seal - an accolade for achieving the highest hygienic standards - and is becoming increasingly popular. “We have seen a steady increase in the number of certifications,” says Dr Jürgen Hofmann, an expert from Weihenstephan and head of the German group within the EHEDG. Pipeline components such as sensors, valves and pumps were prominent among the first elements to be certified. Now, increasingly complex components such as rotary feeders and diverter valves for pneumatic delivery systems are arriving at the test centre. The decisive factor, in addition to the selection of materials, is the design of the components to make them easy to sanitise. This is because intensive and regular cleaning of all of the equipment used is mandatory. Another factor is that this regularly repeated working step must be kept as short as possible, because “whoever designs the cleaning process to be as efficient as possible has the most profitable production”, says Hofmann. Taking sensors, for example - they require significantly less cleaning time if they are integrated in the pipeline with a flush front in a globe housing. 42

March/April 2013

Cleaning-in-place as the best solution In this context, cleaning really means cleaning-in-place (abbreviated to CIP). This royal road to cleanliness has become an essential part of the modern process environment in confectionery production. It is a process in which the cleaning solutions circulate within the production equipment, cleaning it completely automatically, without the need to disassemble any part of the system. To guarantee effective rinsing, it is essential that the tanks, pipelines and pumps are designed without any dead zones and can be completely emptied. In addition, the surface properties of all of the components that come into contact with the product must be as smooth as possible, to prevent the adhesion of soiling, product or microorganisms in joins and niches. On top of all of these considerations, it is also essential not to lose sight of the big picture. Hygiene-conscious producers are always confronted with the question of how the individual machines making up the production line are connected with one another. The chocolate in the coating machine passes through hygienic pumps and pipelines, neither of which exhibit dead zones. But what’s the situation in the self-contained unit? Does it have any corners where product residues could remain for longer periods? Hygienic design was one of the central themes at ProSweets Cologne, which took place in January 2013 with ISM, the International Sweets and Biscuits Fair. Approximately 350 exhibitors from 30 countries exhibited their goods and services in the Cologne exhibition centre. The entire supplier product range for the manufacture, processing and packaging of confectionery and snack items were on display and solutions for the challenges faced at different stages of production were presented.

Compare these Blowoffs

Facts about Blowers

There are a variety of ways to blow the water from the bottles shown in the photo below, but which method is best? To decide, we ran a comparison test on the same application using four different blowoff methods: drilled pipe, flat air nozzles, Super Air Knife™ (each using compressed air as a power source), and a blower supplied air knife (using an electric motor as a power source). Each system consisted of two twelve inch long air knives. The following comparison proves that the EXAIR Super Air Knife is the best choice for your blowoff, cooling or drying application.

Energy conscious plants might think a blower to be a better choice due to its slightly lower electrical consumption compared to a compressor. In reality, a blower is an expensive capital expenditure that requires frequent downtime and costly maintenance of filters, belts and bearings.

The goal for each of the blowoff choices was to use the least amount of air possible to get the job done (lowest energy and noise level). The compressed air pressure required was 60 PSIG which provided adequate velocity to blow the water off. The blower used had a ten horsepower motor and was a centrifugal type blower at 18,000 RPM. The table at the bottom of the page summarizes the overall performance. Since your actual part may have an odd configuration, holes or sharp edges, we took sound level measurements in free air (no impinging surface).

Drilled Pipe

Blower Air Knife

This common blowoff is very inexpensive and easy to make. For this test, we used (2) drilled pipes, each with (25) 1/16" diameter holes on 1/2" centers. As shown in the test results below, the drilled pipe performed poorly. The initial cost of the drilled pipe is overshadowed by its high energy use. The holes are easily blocked and the noise level is excessive - both of which violate OSHA requirements. Velocity across the entire length was very inconsistent with spikes of air and numerous dead spots.

The blower proved to be an expensive, noisy option. As noted below, the purchase price is high. Operating cost was considerably lower than the drilled pipe and flat air nozzle, but was comparable to EXAIR’s Super Air Knife. The large blower with its two 3" (8cm) diameter hoses requires significant mounting space compared to the others. Noise level was high at 90 dBA. There was no option for cycling it on and off to conserve energy like the other blowoffs. Costly bearing and filter maintenance along with downtime were also negative factors.

Flat Air Nozzles

EXAIR Super Air Knife

As shown below, this inexpensive air nozzle was the worst performer. It is available in plastic, aluminum and stainless steel from several manufacturers. The flat air nozzle provides some entrainment, but suffers from many of the same problems as the drilled pipe. Operating cost and noise level are both high. Some manufacturers offer flat air nozzles where the holes can be blocked an OSHA violation. Velocity was inconsistent with spikes of air.

The Super Air Knife did an exceptional job of removing the moisture on one pass due to the uniformity of the laminar airflow. The sound level was extremely low. For this application, energy use was slightly higher than the blower but can be less than the blower if cycling on and off is possible. Safe operation is not an issue since the Super Air Knife can not be dead-ended. Maintenance costs are low since there are no moving parts to wear out.

Here are some important facts: Filters must be replaced every one to three months. Belts must be replaced every three to six months. Typical bearing replacement is at least once a year at a cost near $1000.

• Blower bearings wear out quickly due to the high speeds (17-20,000 RPM) required to generate effective airflows. • Poorly designed seals that allow dirt and moisture infiltration and environments above 125°F decrease the one year bearing life. • Many bearings can not be replaced in the field, resulting in downtime to send the assembly back to the manufacturer. Blowers take up a lot of space and often produce sound levels that exceed OSHA noise level exposure requirements. Air volume and velocity are often difficult to control since mechanical adjustments are required. To discuss an application, contact:

Why hygienic design is essential

Hygienic pump design is the alpha and omega of any successful sanitary production process. Hygienic design implies that the pump is easy to clean and thus is made of materials and components which comply with strict international standards for sanitary applications.

n a number of industries, including food and beverage and pharmaceutical industries, high-grade sanitary pumps play an important role in the production process. If the pump does not live up to the high requirements with regard to safety, design, materials used and material surface finish, this can lead to impurities in the system, potentially causing an entire production to be brought to an immediate standstill. So, cleanability is the essence in any sanitary pump. The most important criterion for the cleanability is primarily an optimum hygienic pump construction that is easy to clean. The circulation space should be free of dead ends.

Unique hygienic design Because quick and efficient cleanability plays such a decisive role in sanitary processes and thus in sanitary pumps, higher safety standards apply for these types of applications than for other processes involving pumps. The Grundfos range of sanitary pumps, designed by Hilge, is made in accordance with the strictest hygienic design criteria both for physical properties and with regard to preventing possible breeding grounds for bacteria and germs. The design requirements and the surface finish of the materials used are of the utmost importance and subject to a wide variety of national and international rules and regulations. Among these are the GMP Rules and Regulations, FDA Regulations, 3A Sanitary Standard, EU Foodstuff Hygienic 48

March/April 2013

Guidelines, DIN EN 12462 Biotechnology, the recommendations of the EHEDG (European Hygienic Equipment Design Group) and QHD (Qualified Hygienic Design).

Materials Strict requirements to hygienic design mean strict requirements to construction of any component that comes in contact with the pumped liquid. Therefore, the selection of materials and their surfaces with regard to cleaning and corrosion characteristics plays an important part when it comes to quality and safety of the entire process. Different factors need to be considered in order to determine these requirements: product safety, consumer protection, reducing cleaning costs with regard to economic and ecological aspects, and legal requirements related to ease of cleaning, etc. Depending on whether the pump is to be used in, for example, the pharmaceutical or food and beverage industry, it is important to specify these requirements in order to get the most suitable pump for the task at hand. To ensure a homogeneous pore-free surface of the sanitary pumps, Grundfos uses AISI 316L (DIN EN 1.4404/1.4435) coldrolled and/or forged stainless steel for sanitary pump construction.

Shaft seals Hygienic design also calls for high requirements with regard to the seal arrangement. Sealing surfaces must be free of gaps, the contact pressure of sealing materials must be well

defined and a hygienic, certified shaft passage or seal must be used. Depending on the requirements, the shaft passage or seal can be located either internally or externally in a single or double arrangement with a connection for flushing water. To ensure trouble-free operation, no matter the application and the pumped liquid, two main types of shaft seal exist: single and double mechanical shaft seal arrangements. The single shaft seals are inboard mechanical seals with an optimum position in the pumped liquid in order to ensure lubrication and cooling as well as CIP (cleaningin-place) and SIP (sterilisation-in-place). The double seal arrangements are either a tandem or back-to-back seal arrangement. All standard seals in the Grundfos sanitary range have seal faces of carbon/stainless steel and O-rings of EPDM (ethylene propylene diene M-class rubber). Other seal face material combinations are available, such as SiC/ SiC (silicon carbide/silicon carbide) for pharmaceutical and biotech applications. Depending on the user’s requirements, Grundfos offers two types of shaft seals for hygienic applications and sterile applications. As standard for hygienic applications, Grundfos offers a single shaft seal fitted with a metal spring as seal driver. This shaft seal has seal faces of carbon/stainless steel and O-rings of either EPDM or FKM (fluoroelastomers). As standard for sterile applications, Grundfos offers a 100%

To meet the different and high demands of the pharmaceutical, food and beverage industries, Grundfos has developed a range of surface finishes designed for specific industries. Impellers and connections are designed and treated in different ways according to international standards in order to handle the pumping task in the best possible manner. All the impellers for the Grundfos sanitary range are electropolished stainless steel impellers and are available in different types of design: semi-open impeller, closed impeller and free-flow impeller designs. Each type is capable of handling a wide range of pumping tasks, such as different viscosity liquids and liquids with a variable content of solids. For pharmaceutical applications where it is a requirement that the surface finish Ra<= 0.8/0.4 µm only semi-open impellers are used. However, channel impellers are available on request. Connections are also subject to different hygienic designs and thus to a wide range of standards. Sterile threads are designed according to DIN 11864-1 PN 16 and sterile flanges according to DIN 11864-2 PN 16. Grundfos also offers a whole range of special connections for special applications such as SMS, RJT, DIN or ISO clamp connections, Tri-Clover connections and ASME BPE 2000.

Approvals and certificates Grundfos wants to protect users’ consumable products from contamination and to make sure that their production is safe and lives up to the strict international requirements with regard to hygienic design. The design, materials used and surface finish are subject to a variety of national and international rules and regulations. All the products in the Grundfos high-grade sanitary range comply with the strict requirements as to hygienic design listed in the 3A Sanitary Standard, the EHEDG and QHD. In addition, a number of special certificates and approvals are available for different purposes such as material certificates and ATEX approved sanitary pumps which have to be ordered with the pump. Customers who require absolute certainty that the delivered Grundfos product complies with the specifications of the order as to surface roughness, for example, can order a certificate on request. This means that if the pump is to be installed in explosive atmosphere, an ATEX- EC Conformity Declaration must be delivered together with the pump.

Brewhouse upgrade helps Florida brewer aim for the stars

PROCESSING

Spacecraft are no longer launched in Cape Canaveral, but a brewer in the region is still aiming for the stars. Starting life as a tiny microbrewery, the Florida Beer Company has become the largest craft brewery in the state. In its first year, the micro-brewery output about 1200 hL, producing two beers and an apple cider. Jim Massoni bought the microbrewery in 2003 after it got into financial difficulties and within two years the Florida Beer Company took over several other microbreweries. From there, the company’s output grew by more than 50% each year, reaching around 34,000 hL in 2011. Massoni upgraded the brewing facility, © www.sxc.hu/wetape investing in bottling kit, marketing, sales and distribution, and purchased an additional warehouse. The old brewery featured a 36 hL brewhouse of American design, a Kosme filler and labeller rated at 3600 bottles/h, plus a kegging line accounting for about half the total output. The bottling operation involved a lot of manual work. Empty bottles were depalletised by hand, while the fulls were also packed in sixpacks and American boxes, and manually palletised. Massoni installed 25 new cylindroconical fermentation and storage tanks, each holding 270 hL, which provide an annual capacity of 78,000 hL. There are already plans for upsizing to 40 tanks for what will then be an annual capacity of 144,000 hL. For the filling operations, the firm currently uses the Kosme bottling line with a capacity of 42,000 hL and the kegging line from the old brewery. There are also plans to invest in a new bottling line. At the heart of the new brewery is the CombiCube B brewhouse. Breweries with a brew size of 40 to 105 hL of cast wort had previously not been able to use Steinecker’s technology, as the customised systems above this rating were not amenable to use in the lower output range. However, Steinecker wanted to offer the right technology for the brewery, so the firm’s creative minds set out to modify the large-scale concepts to suit a downsized output category. The compactly dimensioned frame construction, with specially tailored vessel sizes, is extremely economical on space: the entire brewhouse has a footprint of less than 100 m 2. The individual processes involved in wort preparation are grouped together for enhanced convenience and can be handled by a single operator, whose task is simplified by the higher-order Botec process control system. “What I found particularly interesting was the compact frame construction, which enables it to be prefabricated in the factory, making for shorter installation and commissioning times,” Massoni said. “The CombiCube also scored highly with its modularised design, which means it’s very easy to upsize its capacity. The small footprint, the quality of the

March/April 2013

craftsmanship and modern, energy-efficient Stromboli boiling technology, and not least Steinecker’s excellent reputation, were additional, very attractive arguments.” The CombiCube B brewhouse at the Florida Beer Company comprises three vessels for 104 hL of hot wort: a mash-wort copper featuring Stromboli, a lauter tun and a whirlpool. The brewery produces four brews a day in an infusion mash process. A Variomill wet mill supplies the malt grist. “The CombiCube B now offers us a capacity of well over 100,000 hL,” said Massoni. “With an additional mash

tun, we could very easily triple the number of brews a day, for three times the annual output. It took only four months from placing the order before the CombiCube B was delivered, which was pretty fast compared to a traditional-type brewhouse.” Massoni still sees plenty of scope for expanding his beer sales. Florida is the USA’s third-biggest market for beer, but for a long time consumption of craft beers lagged behind the levels in other states. Now, the growth rate for craft beer consumption in Florida exceeds that in all other states of the USA. “Here in the Sunshine State we have a lot of tourists. And more and more people are turning away from mass taste and asking for local food, local fish, local beer. When the big breweries lose 1%, the craft breweries gain many times that,” Massoni said. In the summer of 2012, the Florida Beer Company produced its first brew in its new CombiCube B. With the capacity now available, the craft brewery is finally able to meet the soaring levels of demand. “We’re extremely confident for our beers and our market,” Massoni said.

Transmitter for pH and ORP measurements

Alarm module for gas mixer

Sensorexâ&#x20AC;&#x2122;s TX-3000 pH/mV transmitter monitors changes in process fluids, displaying pH or oxidation reduction potential (ORP, measured in mV) and temperature for more accurate control in water, chemical, electronics, food production, environmental and wastewater applications. The line-powered device can be user programmed on-site to measure either pH or ORP (Redox). Its dual output design, with an isolated (0)4 - 20 mA output for pH or ORP readings and one for temperature measurement, eliminates the need for a separate temperature transmitter. A large backlit LCD screen displays both parameters simultaneously and two adjustable Hi/Lo relay contacts deliver results to automated process control systems. With an extended pH measurement range of -2.00 to 16.00, the device is suitable for a range of applications. The NEMA 4x, IP65 enclosure can be wall, panel or pipe mounted for easy integration in most installations. The device can be easily programmed on site with its push button interface. The unit can be password protected for secure installations.

The Witt NXT+ alarm module monitors the gas pressures at the inputs of the gas mixer and in the mixing gas vessel to ensure a constant process quality. Witt mixers work with a high-pressure fluctuation tolerance and provide precise gas mixtures even at different input pressures. However, major irregularities in the gas supply can occur. In this case, only alarm modules such as the NXT+ provide protection against unwanted gas mixtures resulting in expensive production failures. The system not only receives signals from the input pressure monitors integrated in the mixers, it also monitors the pressure in the mixing gas vessel. In this way, the entire process remains under control centrally, from the gas input to the mixing gas output. The alarm module is also available as a retrofit. A digital display on the front of the device lets users view the measuring values. In addition, six LEDs signal whether the monitoring is active and the values are within the freely adjustable limit values. A time delay for the alarm can be specified in order to customise the sensitivity of the alarm module and tolerate low pressure fluctuations. An acknowledgement of the alarm reception can also be activated. The system saves the alarm messages to make it easier to track the errors. The alarm limits can also be set quickly and easily via the display. For comprehensive administration, the company provides Alarm Control software. Alternatively, the NXT+ can also be accessed via the system program HyperTerminal, available on most Windows PCs.

Salad manufacturer Sunfresh Salads discharges about 55,000 litres of wastewater from its Adelaide production facility each day. The wastewater contains suspended solids (SS) concentrations of up to 1500 mg/L and fats, oils and grease (FOG) concentrations up to 800 mg/L and is highly variable in pollutant concentration, pH and flowrate. SA Water has set a discharge specification of 500 mg/L for SS and 100 mg/L for FOG. Sunfresh’s wastewater is discharged to the sewerage system and the wastewater quality was regularly exceeding SA Water’s discharge specifications for a number of parameters. The company contracted Aerofloat Australia to install a Model 3500 Aerofloat to treat the wastewater and ensure it meets SA Water discharge requirements. The Aerofloat unit is a miniature dissolved air floatation (DAF) system and was originally developed in 2009 to treat greywater produced on houseboats. Today, there are five different models of the patented product that treat a variety of wastewaters with varying flows. Able to process up to 3500 L/h of wastewater, the Aerofloat 3500 was developed specifically to treat industrial wastewaters and greywater from larger residential complexes. The project included a number of components: conversion of the existing grease trap to a combined primary treatment tank and pumping chamber; provision of screens for removal of large solids; a mixed blending tank for strength balancing and pH correction; installation of a complete Model 3500

Non-invasive airflow measurement equipment Using a clamp-on transit-time correlation technique with ultrasonic transducers simply clamped onto the outside of a pipe means air lines no longer need to be cut to complete an air audit. Southern Cross Compressors’ non-invasive airflow measurement equipment uses digital signal processing and analysis with up to 1000 signals/s and is capable of accurately registering the smallest of airflows, the company claims. By clamping transducers onto the outside of an air line, an accurate profile of a customer’s usage can be obtained independent of the type of compressor or the control system utilised by the compressor. Production is not interrupted and there are no electrical connections, moving or pressure loaded parts to consider. The measuring device can be used on a range of pipe sizes ranging from 7 to 1600 mm with accuracy of ±1 to 3% depending on the application. The pipe and materials parameters are taken into consideration and, using paired calibrated transducers, flow can be determined over an extended period of time. This accurate real-time data is used to determine a profile and to optimise air production and reduce usage. Opportunities to reduce wastage are identified through leaks or pressure, which contribute to lowering energy usage. As an example, a reduction of just 4% can represent total power savings to a similar degree per year, according to the company. An air audit on the supply side concentrates on the compressor room, ensuring the compressor and ancillary equipment is right for the job, the pipe size is correct, ventilation is sufficient and there is ease of access for maintenance. The demand side requires checks for air leaks and inappropriate uses, and looks at ways of reducing demand.

Your system is only as strong as your weakest critical control point Preventing foodborne disease outbreaks saves time, money and reputation.

n outbreak of Listeria, E. coli or Salmonella can cause untold damage to the business and reputation of a food processing plant, but there are some surprisingly simple measures that can help manage the risk, according to Peter Maibom*. “The potential impact of a pathogenic microorganism outbreak is difficult to measure - it could range from the cost of shutting down production for several hours to losing the business altogether due to the damage to supply chain relationships and reputation,” Maibom said. “Anywhere fresh food is being processed is at risk. Understanding the risk and developing stringent procedures is absolutely essential. And beyond that, knowing how to spot the early warning signs of a problem is vital.” According to Maibom, potential outbreaks can be identified before they reach the production line and cause catastrophic problems for plant operators. “There are early indicators that you may have a problem. We urge our clients to regularly test drains and condensates in their air-conditioning units as these tests can give advance warning of a looming problem. If you get a positive result, you have an opportunity to hopefully eradicate the bacteria before it reaches critical levels. The tests are relatively simple and can save a company’s reputation.” Peter says it is also important not to cut corners on cleaning and to work with a specialist who understands how proper cleaning contributes to food safety. “You need to keep the 58

processing facility in a visually clean state, of course, but it’s also essential to ensure it is sanitised according to standard operating procedures. This includes the surfaces you don’t often consider. We have encountered drains that have not been properly cleaned because the covers don’t get lifted up, and uncleaned components in food production pumps. Those blind spots and hard-to-reach places in the production line are often the areas of greatest risk for contamination. “Your system is only as strong as your weakest critical control point.” While prevention is the goal to strive for, Maibom said taking action at the earliest indication of a problem was also essential. “A reliable and experienced cleaning company can give expert advice and train management teams on how to avoid outbreaks so the best option is to work with a quality cleaning company from the start. But if you do encounter a problem, it’s definitely time to call in an expert who can complete a deep clean to ensure the outbreak is dealt with and can then get your processes on track to minimise future risks. “If you feel like you might have a problem, then you probably do.” *Peter Maibom is Director of Ecowize, an Australian hygiene and sanitation service provider to the food industry.

Weighing environment logger A&D has introduced the AD-1687 weighing environment logger that can simultaneously and chronologically record weighing values as well as temperature, humidity, atmospheric pressure and vibration. When connected to a weighing instrument, weighing data (zero point and weight value) and time, temperature, humidity, atmospheric pressure and vibration are simultaneously recorded each time the print key is pressed. Even when the logger is not connected to a weighing instrument, it can be used to log environmental data in locations ranging from cleanrooms and labs to production facilities. By connecting the AD-1687 to a PC, recorded data can be imported into software, such as Microsoft Excel, for data analysis, without using special data transfer software. When connected to a PC, the PC recognises it as USB storage. Data trends can be graphed using automatic scaling and the display of environmental data can be limited to, for example, temperature and humidity. Acquired data, saved to a PC, can be used to calculate span values and repeatability from span values.

The MU study, published in the Proceedings of the National Academy of Sciences, also investigated an estrogenic compound found in plants - genistein - in the same three-year study. “Our findings don’t say anything about the positive or negative effects of BPA or genistein,” said Cheryl Rosenfeld, associate professor of biomedical sciences in MU’s Bond Life Science Center. “Rather, our series of experiments did not detect the same findings as reported by another group on the potential developmental effects of BPA and genistein when exposure of young occurs in the womb.” Creating reliable data on the effects of the chemicals on mice is important to human health since people are frequently exposed to BPA and genistein and humans share similar biological functions with mice. BPA is a chemical used in certain plastic bottles and may be found in the lining

of some canned goods and receipt paper. Genistein occurs naturally in soy beans and is sold as a dietary supplement. Research by Fredrick VomSaal, professor of biological science at MU, and others suggests the chemicals may have other adverse effects on many animals, including humans. Researchers who conducted the original series of experiments claimed that exposure to BPA and genistein resulted in yellow coat colour, or agouti, offspring that were more susceptible to obesity and type 2 diabetes compared to their brown coat colour, healthy siblings. However, Rosenfeld and her team did not obtain the same results when repeating the study over a three-year period. After failing to repeat the original experiments’ findings with similar numbers of animals, Rosenfeld’s group extended the studies to include animal numbers that surpassed the prior studies to verify that their findings were not a fluke and to provide sufficient number of animals to ensure that significant differences would be detected if they ex-

isted. However, even these additional numbers of animals and extended experiments failed to reproduce the earlier findings. However, the current studies demonstrate that a maternal diet enriched in estrogenic compounds leads to a greater number of offspring that express an agouti gene compared to those that do not, even though equal ratios should have been born. “This finding suggests that certain uterine environments may favour animals with a ‘thrifty genotype’, meaning that the agouti gene of mice may help them survive in unfavourable uterine environments over those mice devoid of this gene, Yet, the downside of this expression of the agouti during early development is that the animals may be at risk for later metabolic disorders, such as obesity and diabetes,” Rosenfeld said. “In this aspect, humans also

have an agouti gene that encodes for the agouti signalling protein (ASIP) that is expressed in fat tissue and pancreas, and there is some correlation that obese individuals exhibit greater expression of this gene compared to leaner individuals. Therefore, the agouti gene may have evolved to permit humans the ability to survive famine, but its enhanced expression may also potentiate metabolic diseases under bountiful food conditions.” While the research casts doubt on the previous study, Rosenfeld said that by understanding the genetic profile of the mice in the first series of studies, scientists could learn more about the correlation between certain genes and obesity. This could eventually influence prevention and treatment programs for patients with diabetes and other obesity-related diseases in humans.

Bulk fluid system for continuous ink jet printers Seal seam scanner The Multivac Vision System MVS seal seam scanner from Multivac Marking & Inspection is an inspection system which checks the quality of seal seams during the packaging procedure. The system scans the seal seams while they are still in the thermoforming packaging machine and faulty packs can be detected before they are dispatched. The inspection is fully automatic and captures 100% of

Videojet Technologies has announced a five litre bulk fluid system (BFS) for its 1000 Line continuous ink jet printers. The BFS is suitable for users running high-volume print applications such as bottle and can. According to the company, the BFS means fewer cartridges to change, giving users longer runtimes and less intervention with their Videojet continuous ink jet printers. The Videojet BFS accessory is a large-capacity bulk fluid container for ink or make-up that can easily integrate into many continuous ink jet printers including: 1610, 1620, 1610DH, 1520 and 1710 (make-up only). Mounted anywhere within one metre from the ink jet printer, the BFS has a needle and septum design that keeps fluid replenishment clean and simple. The Smart Cartridge design makes the system easy to use. Once inserted, the printer reads an embedded microchip on the bulk container to verify it is the proper fluid type and has not passed its expiration date. Production line operators can enjoy the benefits of a bulk system without the risks of contamination or mismatching fluids. Tronics Pty Ltd Contact info and more items like this at wf.net.au/S837

all packs without any contact, making the system wear free. The scanner detects foreign bodies in the seal seam from a size as small as 0.5 mm 2, as well as detecting incomplete seal seams or faults such as creases or bubbles. The system is suitable for all film materials; at least one of the two films must be transparent. The scanning range is up 700 mm width. The rapid image processing of the scanner ensures that there is a high level of throughput. The line scan camera is integrated in the thermoforming packaging machine as is the lighting, and the brightness can be adjusted. A further advantage is its small space requirement, the thermoforming packaging machine is only 60 cm in length. No additional transport conveyor system is required for the operation within the packaging machine of the seal seam scanner. It can be easily retrofitted to existing machines and is maintenance free.The system also supports the traceability of packs, since it has an image archive of faulty products complete with time signature as well as a machine logbook.

Packaging

In response to the pervasiveness of frustrating, impenetrable and potentially dangerous packaging, CHOICE has launched Pack Attack, a campaign calling on manufacturers to adopt packaging that doesn’t require knives, scissors or super-human strength for access. “Many items are now so wrapped up that some consumers simply cannot open them. Trying to bust out an electrical item sealed in a hard plastic container or twist open a vacuum-sealed glass jar is not only prompting ‘wrap rage’ but also leaving some people injured,” said CHOICE’s Angela McDougall. To tackle the problem, CHOICE is calling on consumers to send in their photos and a description of examples of bad packaging. The consumer group will then make a complaint on their behalf to the Australian Packaging Covenant (APC) and report back on responses from manufacturers. “While packaging accessibility can affect us all, it is a particular problem for those suffering from arthritis, poor eyesight, reduced hand strength as well as some older people,” McDougall said. CHOICE is calling for consumers to email photos of offending packaging or post them to their social media outlets.

NT government takes on beverage manufacturers over CDS Debate over the Northern Territory Container Deposit Scheme (CDS) is heating up, with three large beverage manufacturers claiming the CDS legislation is legally invalid. The Northern Territory Government is fighting these claims, made by Coca-Cola Amatil, Schweppes Australia and Lion Pty Ltd. The case will be heard in the Federal Court of Australia on 19 February to determine the outcome. The NT Government is encouraging Territorians to watch the court challenge via a video link in the Supreme Court in Darwin. “This is an issue that could affect many Territory families who regularly utilise this as a means of reward-based recycling,” said Chief Minister Terry Mills. “Since 3 January 2012, more than 35.5 million containers have been processed through the scheme. “There are also many Territory businesses with a financial interest in the scheme, which is why we applied to the Court to gain this video link and ensure Territorians can watch proceedings. “This government is committed to fighting this important challenge. The most senior lawyer in the government, the Solicitor-General, and his team have been briefed to pull no punches in meeting this legal challenge.”

Uncle Tobys breakfast cereals first major range to pass new health claims nutrient criteria

PACKAGING

The Standard for Nutrition, Health and Related Claims became law on 18 January 2013. The Standard creates stricter controls about on-pack nutrition content claims and health claims and restricts the use of health claims to just those foods and beverages which meet specific levels of both positive and less desirable nutrients, measured in the nutrient profiling scoring criterion. All 44 breakfast cereals in the Uncle Tobys range have now been confirmed as meeting the nutrition requirements of the new government food standard which determines whether products can make health claims. The Uncle Tobys range is the first of the top three breakfast cereal ranges to fully comply. The announcement is the culmination of a five-year program to reduce saturated fat, sugar and sodium across the Uncle Tobys range while increasing wholegrain and fibre. Uncle Tobys Nutrition Manager, Nilani Sritharan, said recipe changes mean the Uncle Tobys range is now using 67 tonnes less sugar and 2.5 tonnes less sodium, while adding 193 tonnes more wholegrain and 13 tonnes more fibre each year.

Diabetes Council welcomes new labelling laws The Australian Diabetes Council (ADC) has welcomed the introduction of the new Standard 1.2.7 - Nutrition, Health and Related Claims, which became law on 18 January 2013. Dr Alan Barclay, ADC Head of Research, said the new system is a significant improvement as it will allow food manufacturers to more clearly communicate to consumers the health benefits of their products. “For many years manufacturers have had to rely on limited nutrient content claims like ‘low fat’ to imply that a food is a healthier option, and higher level claims have been prohibited,” Dr Barclay said. “The new system will enable a manufacturer to communicate the health benefits more directly.” The ADC supports the requirement for higher level health claims to only be allowed on food and drinks that meet Food Standards Australia New Zealand (FSANZ) nutrient profile scoring criterion, Dr Barclay said.

Plastics recycling facility to be built in Queensland The Australian Packaging Covenant has announced joint funding of a state-of-the-art plastic recycling facility to be built this year in Queensland. Stan Moore, CEO of the Australian Packaging Covenant (APC), said, “The APC has identified a need to increase the recovery and recycling of plastic waste in Queensland, and industry - through the APC - is pleased to collaborate with the Queensland Government and Replas to make this happen.” The APC and Queensland Government will provide equal funding totalling over $600,000 towards the establishment of the plant in South East Queensland. The Replas facility will be the only operation in Queensland able to process a full range of soft and rigid waste-plastic packaging materials. This will divert plastic packaging waste like shopping bags, shrink-wrap films and sterile wrap from landfills. The facility will reprocess locally collected plastic waste and initially produce products such as bollards. These can then be used for infrastructure throughout Queensland, returning this resource to the community that created it. Additional products will be added to the production line over time. Recycled-plastic products provide an alternative to timber that is not only more durable, but also better suited to harsh environmental conditions. This could prove a boon in areas such as North Queensland which experience high temperatures year round. The facility will utilise the latest robotic technology developed by Replas.

technology. This technology allows for the efficient and low-cost production of wide-mouth containers by using standard narrow-neck preforms, eliminating expensive injection-mould tooling and saving energy, resins and cycle times. The wide-mouth finish is built into the same bottle mould rather than into the preform. The blow-moulded jar has two portions: the threaded neck finish and an upper dome that is removed in an on-line process. This provides processors with a lightweight, unbreakable jar alternative to those made of glass. The machine is versatile, as it enables the handling of containers which do not require cutting to pass through the on-line machine, saving a bypass of the cutting machine. It can process necks with diameters ranging from 45 to 110 mm. HBM Packaging Technologies Contact info and more items like this at wf.net.au/T048

Recycling and risk

PACKAGING

The issue of Mineral Oil Hydrocarbons (MOHs) migration into foods continues to grow. Not all news on this issue is consistent and it is another challenge to packaging technologists. MOHs are by-products of crude oil refinement used in inks, adhesives, lubricants, plasticisers and protective coatings. When ink is applied to a surface like newspaper, the mineral oils absorb and attach to the paper fibre. Most of the oil attached to the fibre remains once the newspaper enters the recycle stream. Mineral oils can accumulate in organs and endanger human health. Results from a 2010 survey of German supermarket products indicated 75% exceeded EU safe limits. Major food manufacturers changed their packaging amid concerns over the long-term health hazards of MOHs leaching from recycled cardboard into foods. UK breakfast cereal producers Kellogg’s, Weetabix and Jordans all took steps to change their packaging. In 2011, the Confederation of European Paper Industries and the International Conederation of Paper and Board Converters announced a commitment to phase out printing inks with mineral oils for printing paper and board packaging. In 2012, the UK Food Standards Agency published a survey concluding that consumers need not be concerned. To add to the cloudiness, the European Food Safety Authority published a report on human exposure to mineral oils. Their experts on the Contaminants in the Food Chain panel identified some potential concerns regarding exposure to MOH through food. However, they highlighted several uncertainties regarding the chemical composition of MOH mixtures and a lack of toxicological studies. The EFSA called for an overhaul of Acceptable Daily Intake levels and suggested new measures to assess and monitor the risk from the substances. Packaging companies in Europe have been promoting that they have products that have effective barriers against MOHs. Consumer product companies have started demanding that packaging suppliers provide certification that any recycled paper they are using has at least low levels of mineral oil, if not free of it. This is not the end of this issue. While we are advocates for recycling and recycled content in our packaging, this is an issue for packaging technologists to grasp quickly. The solution is to gain knowledge, work closely with packaging suppliers and understand all steps of your packaging supply chain.

Eastman Chemical Company has added the Aspira One polymer to its portfolio of resins. Carrying resin identification code 1 (RIC 1), Aspira One is designed for extrusion blow moulding (EBM) processes and packaging applications such as clear handleware and large-size bottles. A polyethylene terephthalate (PET) polymer, it is claimed to provide an optimal balance of recyclability, product performance, production efficiency and aesthetics versus alternative polyester resins available to the EBM market. The polymer is sustainable, being compatible in the PET recycle stream and carrying RIC 1. It received recognition from the Association of Postconsumer Plastic Recyclers (APR) in July 2012 for meeting the PET Bottle Critical Guidance Document protocol. Aspira One enables the design of unique, clear and glossy containers, such as handles, through holes and other features that can only be obtained by the EBM process. For bottle performance, the material offers robust toughness and is free of bisphenol A and halogens. The polymer’s clarity allows consumers to see the contents of their packages, providing product differentiation and shelf appeal. In contrast with other polyester resins for EBM, the polymer is an amorphous, melt-phase produced material. Because Aspira One pellets are not crystalline or solid-stated, they can be dried and processed at lower temperatures than other PET resins. This lowers energy usage, improves melt quality and minimises thermal degradation of the polymer. Crystallisation of bottle flash regrind is not required because Aspira One pellets are amorphous and thereby compatible with the regrind in a dryer set-up. It does

Supplied as either complete systems or on a modular basis AFPM work with clients to design systems to maximize productivity of filling operations.

Checking packages of food and pharmaceuticals for leaks, a cause of quality loss or other damage to an enclosed product, is made simple with the bench-mounted Seal Tick TSE2032 Underwater Water Vacuum Leak Tester. The TSE2032 is suitable for detecting production line sealing equipment faults and remedying other sealing problems before production starts, or as a routine sample check. Minute leaks from pinholes and imperfect seals can be observed from any part of the package through the TSE2032â&#x20AC;&#x2122;s clear acrylic test chamber. An O-ring embedded in the lid of the test chamber lid ensures the chamber is fully sealed during the test cycle and damage due to wear and tear is minimised. To test a package, the operator lifts the lid of the leak tester and places the package in the test chamber. The lid - which has an integral perforated grid - is manually lowered and the package is fully submersed. Turning a compressed air valve on via a lever on the side causes a partial vacuum to be drawn in the atmosphere above the water. As the vacuum reaches a preset level the package swells and air within the package is drawn out through any pinholes, causing a stream of bubbles to rise to the top of the water. Bubbles escaping from the top side of the package are clearly visible from the top of the tester. A vacuum generator is fitted to the lid of the test chamber

Sustainably produced carton packs with lightweight screw cap Visyâ&#x20AC;&#x2122;s combibloc EcoPlus is now available with the lightweight combiCap screw cap, which weighs 1.9 g. combibloc EcoPlus is constructed of 80% of a type of raw paperboard based on wood, which gives the carton pack stability. All combibloc EcoPlus carton packs carry the FSC label, which confirms that the wood fibres processed to make the paperboard come from FSC-certified forests or other controlled sources. A thin polyamide layer serves as an additional barrier to protect the product from flavour loss and external odours. The package also has fine polyethylene layers inside and outside. The inner polyethylene layer forms a liquid barrier for the product; the outer layer keeps moisture out. Owing to this material composition, combibloc EcoPlus is claimed to generate 28% less

The combicCap screw cap is applied on an over-coated hole, which is punched in the raw paperboard before it is laminated. The closure, which is applied to the carton pack after the product has been filled, can be easily opened by the consumer, as the cardboard layer has already been removed and only the thin polymer layers need to be opened. The closure consists of a flange with integrated cutting ring and a screw cap. With a single twist of the screw cap, the tamper-evident feature on the original seal is broken with an audible click. This allows consumers to clearly identify whether a carton pack still has its original seal intact or has already been opened. To reclose, the cap is screwed back on.

Swift service seals the deal

PACKAGING

While slow and steady supposedly wins the race, speed is essential to winning new business. After two decades of supplying flexible packaging solutions to an international customer base, KM Packaging Services knows the importance of speed when securing new clients. The company says its speedy turnaround was what secured its latest order from Australian fresh food producer GA Zimbulis and Sons. Zimbulis approached UK-based KM Packaging to help ©iStockphoto.com/ mediaphotos it meet a tight launch date for a new range of ready-to-roast meals. Following an in-depth review of the product specifications, KM Packaging was able to quickly identify the most suitable lidding film material, carry out initial performance tests on comparable aluminium foil trays and deliver trail reels overnight to Zimbulis’s production facility in Canning Vale in Western Australia. The rapid response time allowed Zimbulis to undertake its own material assessments and learn how the lidding film would perform within real processing environments. “KM Packaging’s speed of response has been impeccable and we have been hugely impressed by the service we have received,” said Michael Leen, Product and Business Development Manager for Zimbulis. “Despite being over eight thousand miles away, our trial film reels arrived almost instantly and our full order was on site with us within a week of us placing our PO. “Not only has KM Packaging been able to respond directly to our needs very quickly, but this has, in turn, helped us to meet the needs of our customer and ultimately help them launch a very successful product without any technical issues.” Zimbulis’s key requirement for the lidding film was that it would deliver a reliable and secure seal that would ensure maximum product safety. Zimbulis found that the material supplied by KM Packaging demonstrated superior ‘sealability’ and ‘peelability’. From a retailer’s point of view, this enabled maximum shelf life and security; from the point of view of consumers, it was easy to use. Made from polyester-based laminate, the high barrier lidding film is suitable for sealing meat products and other gas flush applications. In addition, it has excellent antifog and hot tack properties. Zimbulis’s product comes with a watch-strap sleeve around the aluminium tray, so the clarity of the film was essential to maximise shelf appeal. “The material supplied by KM Packaging is of extremely high quality,” Leen said. “The performance of the film has been outstanding and we are thrilled that our customer has been able to achieve the shelf life and beautiful presentation that they wanted. “This could not have been done without the guidance and expertise from KM Packaging and we would be more than happy to recommend them to food manufacturers all over the world. “Although the company is based in the UK, it operates like a local supplier. The efficiency of the KM Packaging team has been wonderful and no matter where their customers are in the world, we are confident that they will experience the same impressive level of service as we have.” KM Packaging Services Ltd Contact info and more items like this at wf.net.au/S699

Beverages The rise and rise of breakfast drinks

BEVERAGES

The popularity of breakfast drinks like Sanitarium’s Up & Go has gradually increased in recent years, with the percentage of Australians purchasing them in an average four-week period growing from 4.1% to 7.7% since 2008. According to recent findings by Roy Morgan Research, Australians aged under 25 are the main drivers of this increase, with just over 13% buying breakfast drinks in an average four-week period. The 35- to 49-year-old demographic also seems to be developing a taste for drinking their breakfast: in just two years, the number purchasing these drinks has more than doubled. Norman Morris, Industry Communications Director, Roy Morgan Research, says: “It’s no surprise breakfast drinks are one of the few non-alcoholic beverages gaining popularity among young Australians, as Roy Morgan Single Source reveals this group are 44% more likely to agree with the statement ‘I seldom have time for breakfast’. “Interestingly, a similar proportion of 25-34 year olds also agree with the statement - but the number of people in this age group who consume breakfast drinks appears to be declining. “With Sanitarium’s Up & Go being the most popular breakfast drink, and very few other brands offering products in this growing category, the opportunity for a new alternative ‘on-the-go’ breakfast drink is glaringly obvious.”

Coopers has announced it will retain its Celebration Ale as a permanent line. The product was introduced in 2012 to celebrate the brewer’s 150th anniversary. Coopers’ National Marketing Director Cam Pearce said strong sales of more than 100,000 cases since the ale was launched in May 2012 have driven the decision. “Celebration Ale was initially launched as a special one-off product to celebrate our landmark anniversary,” Pearce said. “However, we said that if it performed well, consideration would be given to keeping it as one of our regular lines. Sales have exceeded our expectations and we have made the decision to make it a permanent part of our portfolio. “Indeed, Celebration Ale was the number-one new product development in packaged beer by value for the quarter ending October 2012, according to Nielsen data.” Celebration Ale is a hops-driven ale with a dark-red hue that follows the style of an India Pale Ale. It incorporates three different hops varieties Centennial from the USA, Nelson Sauvin from New Zealand and Pride of Ringwood from Australia - to produce a beer with strong estery characteristics and a ‘hoppier’ style than Coopers’ mainstream ales. “The fact that it has been able to carve out a strong following in an increasingly busy sector of the market in a relatively short period of time is a strong endorsement of our brewers’ abilities,” said Pearce.

The celebration continues

V8s for Australians living in poverty Campbell’s has donated 225,000 serves of vegetables to Australians in need to mark the official opening of its $14.6 million dollar PET line at its Shepparton facility. The company donated 15,000 1.25 L bottles of V8 juice, the equivalent of 225,000 serves of vegetables, to Foodbank Australia, which will distribute the juice to welfare agencies across the country. The new facility uses the first large-scale PET aseptic technology in Australia to manufacture the V8 vegetable juice range in lightweight packaging for the first time. “We understand the challenges of Australian-based food manufacturers needing to compete in a global marketplace,” said Peter Ryan, Deputy Premier of Victoria, who welcomed the company’s investment. “I congratulate Campbell’s for showing the foresight and commitment to make this major investment, which will help secure the future for this iconic Australian manufacturing site.” In the past seven years, Campbell’s has invested more than $45 million upgrading its Shepparton facility, which produces more than 55,000 tonnes of food and beverage products each year.

Milk just got lighter: world’s lightest HDPE milk bottle created UK plastic milk bottle producer Nampak claims to have created the world’s lightest four-pint high density polyethylene (HDPE) bottle, weighing just 32 gr . Standard four-pint milk bottles found in British supermarkets weigh 40 g, meaning that the new Infini bottle represents a 20% material saving. The Infini bottle, which is stocked in a number of major retailers including Marks & Spencer, Morrisons and Sainsbury’s, is claimed to be the lightest and strongest bottle currently on the market, but Nampak was able to further reduce the bottle’s weight. The company says the lighter bottle could result in significant environmental improvements for the wider milk sector. If Nampak were to move its annual output of 2 billion bottles to the lighter Infini, 15,000 tonnes of resin would be saved each year. If the Infini bottle were to be used UK-wide, it would reduce the overall amount of resin used in UK milk packaging by 30,000 tonnes - a saving of 25%. “Since its launch in 2012, Infini has been responsible for a paradigm shift in milk packaging, using considerably less material and more recycled plastic than has ever been achieved before,” said Eric Collins, Managing Director of Nampak Plastics. “Feedback on Infini from milk processors and retailers has been extremely positive - and we know from extensive research that consumers also prefer the design to the standard bottle. “However, at Nampak we’re always aiming to push innovation boundaries and our environmental leadership credentials as far as possible. With this in mind, we believe that we’ve reached a new pinnacle with the creation of a 32 g four-pint Infini bottle.”

Dairy prices are likely to increase further in 2013 due to tightening supply and steady demand, according to a recent Situation and Outlook report from Dairy Australia. While international demand for milk has been steady, buyers are unsure if more milk being produced by New Zealand herds will offset reduced growth from the EU and USA, the report said. “Most buyers are in a comfortable position regarding stocks, with little urgency to enter the market in late 2012,” said Dairy Australia’s industry analyst, Norman Repacholi. Higher input prices are placing an increasing strain on US and EU milk producers, which is slowing growth in those regions, Repacholi said. “In NZ, milk production has been strong for 2012/13. While it’s unlikely to stay as far ahead in the second half of the season, milk production will still be 3 to 5% ahead of last year,” Repacholi said. This year, the average southern farmgate is likely to finish around $4.90 to $5.10 kg/MS (approximately 36-38 cpl), the report said, around 8% lower than 2011/12. © www.sxc.hu/Marijnvb

NEWS Dairy prices to increase further

“Where the Australian dollar moves, relative to processor budget forecasts, will be the key driver in the final season milk price,” said Repacholi. “It will also help determine when the next step-up is made.” Nationally, milk production forecasts have been lowered to flat-to-0.5% to around 9.5 billion litres as a result of increasingly difficult seasonal conditions and farmgate margin pressure. Analysis of supermarket sales volume data revealed that the branded milk share of supermarket sales has rebounded, but Dairy Australia says it’s too early to confirm if the rebound results from increased promotion or the introduction of permeate-free products. The average price per litre for fresh white drinking milk is down, but Dairy Australia notes that average prices for the higher value-added branded modified milks are lagging further behind, bringing the overall average down. The Situation and Outlook report is funded by the dairy service levy. The full report is available from www. dairyaustralia.com.au.

Genes may drive us to (soft) drink

BEVERAGES

There could be something in the phrase, “I’m not fat, I’m just big-boned”. Endocrinologists from the Garvan Institute of Medical Research have applauded a study that shows a direct correlation between consumption of sugary soft drinks, obesity and genetic predisposition to weight gain. Associate Professor Jerry Greenfield, Professor Katherine Samaras and Professor Lesley Campbell wrote a letter to the editor of the New England Journal of Medicine (NEJM) to commend the study and underline the degree to which appetite is genetically determined, rather than being just a lifestyle choice. “Our point is that people are consuming more calories because their genes are driving them to do so,” said Associate Professor Greenfield. “Genes not only drive people to eat more, they also predispose at-risk people to gain more weight with calorie overconsumption. It’s a double whammy.” The NEJM article in question found that, in three large groups of men and women, those with more obesity genes tended to drink more soft drink and have a greater BMI. The Garvan researchers believe that public health policy could be better targeted if policy makers understood that, for some people, appetite is not something they can control. “Policy should reflect the scientific basis of food intake - in other words, people who eat too much and put on weight are not just over-consuming because they are greedy, they actually have a very strong drive to eat,” Greenfield said.

Driving energy-efficient beer production

BEVERAGES

During 40 years of around-the-clock operation, the Forst brewhouse produced 25 million hectolitres of beer. Recently, Forst management decided to construct a new brewhouse that is highly efficient, complies with the latest safety requirements and produces the lowest possible emissions. The change paid off: in the first week, the new brewhouse reduced its primary energy consumption by 30%. The project was ambitious. Engineers and technicians had just 16 months to construct the main components from scratch, including five large vats, as well as the technology and piping systems, a newly designed water supply, a malting plant with 12 silos and three storage vats. NORD Drivesystems assembled the geared motors for all the vessels according to the specific requirements, from the grinding mill - which grinds the malt at the start of the brewing process - to the screw conveyor which removes the spent grain. In the first stage of the process, the malt is mixed with spring water in the mash tuns and heated by thermally optimised conducting surfaces. A frequency-controlled NORD helical bevel gear motor with a temperature sensor drives the agitator inside the vessel. Subsequently, the liquid is pumped into the lauter tun. Measuring 8.6 m in diameter and weighing almost 21.5 t, the lauter tun is the heart of the brewhouse. Liquids and solids are separated in a fully automated process. The spent grain settles on the vat floor, forming a natural filter layer. A raking machine loosens this layer to ensure optimum flow of the wort. Pressure sensors at the bottom of the vessel detect the spent grain’s consistency and the drive adjusts the machine’s speed accordingly. This intelligent control system enables flow rates between 9 and 14 litres per minute and square metre. Next, the machine is lowered and flat bars push the spent grain out of the tun. This step is also fully automatic. If too much mass accumulates, the lowering process stops and the speed is adjusted. In order to process the material gently, the spent grain is loosened at low speed. When the spent grain is removed, high speeds are required so the vessel can be emptied quickly. Thus, the clouding of the spent grain is minimal and the flow is very efficient. Speed, current consumption and motor temperature are monitored continuously. These tasks are handled by a custom NORD drive unit based on a splined hollow shaft. The drive is a combination of a motor, industrial gear unit and helical bevel gear unit. It has a maximum torque of 96,000 Nm and continuously regulates the circumferential speed from 1 to 100 m/min while providing a constant torque. The lifting device lifts and lowers the raking machine accurately to the millimetre, even under full load. A limit switch and optical sensor ensure exact positioning. The height can be adjusted during standstill, in an idle phase and during operation. To this end, both the helical gear unit and the oil-hydraulic lifting unit are designed to withstand the axial and radial loads which occur in the process. The drive motor has an 18.5 kW power rating and provides output speeds of 0.04 to 4 rpm. “Constructing the new brewhouse, we wanted to ensure that the resources would be processed as gently as possible,” said Dr Walther Unterthurner, the brewery’s technical director. “Furthermore, we wanted to use these modern technologies to considerably reduce energy consumption and emissions.” A heat recovery system has also been integrated into the vapour condenser. The heat required to produce the wort is stored in hot water tanks and is re-used for subsequent brewing processes. According to Unterthurner, these measures have already reduced the consumption of primary energy by 30%. “Our target is to reduce steam consumption by at least 47%,” he added.

Beverage manufacturer’s innovative approach pays off

BEVERAGES

For anyone who grew up in Melbourne, Slades’ home-delivered soft drinks are an institution. Established in 1867, the company traded as O’Neil Brothers Soft Drinks until 1930 when the beverage producer took on Slades as its moniker. Today the company is run by the Tan family, who took over in 2001. “The first 12 months after we took over were hard,” said George Tan. “There were quality issues, inconsistency with product. We had to change all of that. We looked at the manufacturing process and improved it.” The Tans built new warehouses with new manufacturing equipment, moved to plastic bottles and started a new line. At the time, the Slades business wasn’t strong enough to sustain the business, so they started to pack for retailers including ALDI. “Before we worked with ALDI, our practice was to use only cardboard cartons. ALDI wanted to eliminate cardboard cartons by using the CHEP Multi-Purpose Beverage Tray and Display Pallet. From our point of view it was a good move. Using the Beverage Tray we do not have wastage through damage from cartons,” said George. “Also, when using cartons you need different cartons with different barcodes for different flavours; with the CHEP Multi-Purpose Beverage Tray and Display Pallet, you can visibly see what flavour it is - and we do 10 different flavours for ALDI. It saves costs because it eliminates the need to print different cartons and also saves us time because we don’t have to stop the line to change cartons. “Using the Multi-Purpose Beverage Tray and Display Pallet, we have improved line speeds by at least 50% - it’s very impressive actually. Our products have to get out of the door quickly and now we can run four different flavours in a day without stopping the line.” Slades installed a new line to meet the demand for its third-party retail orders. The process is largely mechanised and works seamlessly with the CHEP Multi-Purpose Beverage Tray and Retail Display Pallet. A robot picks up 48 bottles, the number that fills two Multi-Purpose Beverage Trays, and places them on the tray. Two robots then pick up the trays and stack them on a Display Pallet (which is exactly the size of two Multi-Purpose Beverage Trays and one third of the footprint of a standard wooden CHEP pallet). When the stack reaches five high it moves down the line for wrapping. The process is twice as fast as hand-stacking, achieving an average output of 100,000 bottles a day. “Initially we had some difficulties, particularly around transport. I wanted to know how it was going to work, but CHEP eliminated a lot of those concerns. The Display Pallet is one third of the size of a standard CHEP pallet so we are still able to maximise our loads,” George said. In modular terms, six Display Pallets fit the same footprint as two wooden CHEP pallets. Australian truck trailers are designed to be two CHEP pallets wide. “Installing the new line has been worth it,” George said. “The robots can pack all of the ALDI bottles into a MultiPurpose Beverage Tray then onto Display Pallets; and where we still use cartons for some customers, it can also automatically pick up and stack them onto a traditional CHEP pallet. Previously this was a very manual process. We can switch from cartons to Multi-Purpose Beverage Trays and Display Pallets anytime to meet our customers’ needs. “Switching to using the Multi-Purpose Beverage Tray and Display Pallet opened up a market opportunity for us. When the soft drinks come off our line it’s a retail-ready product - it goes straight to the store - that’s what we really like about it,” George said. “I like that there’s high visibility of the product. It’s just in your face. Customers can see the label and touch it, it just stands out. It’s going to save costs over conventional cartons from a manufacturing point of view and also we have learnt that it does increase sales. “It’s a big investment but it’s a long-term prospect. We know over the next five to 10 years retailers will move into RRP (retail-ready packaging) - if you travel around Europe it’s all being packed into RRP. Our view is it’s better to do it now and be ready for the future. “In the manufacturing world you have to be innovative and ready for change.” CHEP Australia Contact info and more items like this at wf.net.au/T000

TESTING & INGREDIENTS

Ancient ‘lost’ grain is found again in Australia

Alice Richard

Ancient grains seem to have the most exotic names: consider the unusual quinoa, amaranth and einkorn when compared with the pedestrian wheat, barley and rye. But the most recent ancient grain to attract attention has the least exotic name imaginable: teff.

raditionally grown in the highlands of Ethiopia, teff (Eragrostis tef) has been grown successfully in South Africa and the United States. But the little grain that packs a punch could soon be grown in Australia, thanks to research by the Rural Industries Research and Development Corporation (RIRDC) and TasGlobal Seeds.

Small but mighty While teff may be the smallest cereal crop ever developed by humankind, don’t let its size fool you. On average, 1000 teff seeds weigh 0.3 to 0.4 grams - 150 grains of teff weigh as much as one grain of wheat. In fact, its name comes from the Amharic word téf, meaning lost - a reference to its size. But its fibre content is very high compared with other grains - as much as 15.3 grams of fibre per 120 grams of flour. It contains many times the amount of calcium, potassium and other essential minerals found in an equal amount of other grains, more lysine than barley, millet and wheat, and is high in protein.

TasGlobal Bob Reid, co-founder of TasGlobal Seeds, first became interested in teff when his daughter was diagnosed with gluten intolerance. Reid contacted the Australian Tropical Crops and Forages Collection (ATCFC) in Biloela, which sent him a sample of 20 teff seeds.

Having planted the seeds, Reid thought he’d never see them again, given their miniscule size. But each seed took and from those original 20 seeds, Reid has selected and re-selected until he’s come up with two strains that he thinks will be most suitable for growing in Tasmania. Teff is an annual, tropical grass that grows at altitudes of 1000 to 2500 metres in Ethiopia. It grows in the Ethiopian summer and is frost sensitive (yes, they do experience frosts in Ethiopia - who knew?). The temperatures are similar to those experienced in Tasmania. Southern Tasmania was selected as the ideal region for growing teff as it has similar temperatures but, being coastal, is not prone to summer frosts - these are the “kiss of death” for teff, according to Reid.

In demand Since word got out that TasGlobal was conducting growing trials for teff, Reid says they’ve been “swamped” with interest from people wanting to buy teff, both in Australia and overseas. TasGlobal has received enquiries for quantities as small as 500 grams, to as much as 10 tonnes. Currently, all teff in Australia that’s available to consumers is imported; none is grown here commercially (although it does grow wild in parts of NSW and Queensland). In Idaho, in the United States, farmers growing teff simply cannot keep up with

www.foodprocessing.com.au

March/April 2013

demand for the grain. Once commercial production begins in Australia, it’s likely to be similarly in demand, Reid predicts. TasGlobal is currently conducting trials to determine how best to grow the crop and what sort of yields can be expected. Once the current crop comes off, Reid says, commercial contracts will be put out in Tasmania.

TESTING & INGREDIENTS

Potential markets The growing gluten-free sector in Australia may well benefit from teff being grown domestically. Reid says it is likely to be used in products such as gluten-free muesli. It can be used in similar ways as wheat flour, Reid says, and although it may not be suitable for light, fluffy cakes, it’s certainly suitable for biscuits and breads.

While visiting Denmark last year, Reid noted considerable interest in teff from the athletic community. A number of successful, long-distance runners come from the Ethiopian highlands and have a diet high in teff, so teff is being considered as a potential ingredient in functional foods marketed to sports people. Since it’s not as high yielding as wheat, teff is likely to be more expensive, which could affect the way it’s used. Rather than being used as the sole or major ingredient in a product, Reid predicts it’s likely to be used as one ingredient of cereal products to increase their protein and fibre content or to increase variety in gluten-free products. While it’s unlikely to rival wheat in the Australian diet, teff looks poised to join the growing ranks of ancient grains being embraced the world over.

Detecting arsenic and nanomaterials in food The Technical University of Denmark’s (DTU’s) National Food Institute has adopted a Thermo Scientific iCAP Q inductively coupled plasma mass spectrometer (ICP-MS) for research supporting European Commission (EC) development of standards for arsenic and nanomaterials in food. Dr Erik Huusfeldt Larsen, senior researcher at The National Food Institute and his Metals, Minerals & Nano Group at DTU are using the iCAP Q ICP-MS system to determine the species of arsenic found in food samples. EC researchers have found that it is no longer adequate to measure total arsenic in food because small amounts of inorganic arsenic can be associated with diseases such as cancers of the skin and bladder, while organic arsenic is much less toxic. Larsen notes that until recently, arsenic contamination was associated mainly with fish and other marine products, but in recent years, arsenic found in drinking water, rice and wheat have also attracted public attention. This work supports the European Conffidence project, which aims to develop easy-to-use methods of analysis for contaminants, including inorganic arsenic. In this project, the iCAP Q instrument will be used for selective and sensitive detection of arsenic following solid-phase extraction. Dr Larsen’s group also collaborates on the EU-funded NanoLyse project that is involved in the determination of nanoparticles including silver, silica and organic nanoparticles in the food matrix. The iCAP Q system will be used in ‘single particle’ ICP-MS mode for determination of metallic nanoparticles in food. “This technology gives us the capability to detect and count individual nanoparticles in food, and this is very important,” said Dr Larsen. “We need to know more than just the size of the particles present, we must also be able to determine the number-based size distribution of particles in a sample. This matters because toxic effects are likely to be associated with the huge surface area of nanoparticles.” “Our company has enjoyed supporting the work of the National Food Institute for a number of years, and this cooperative effort is an extension of this relationship,” said Adrian Holley, Thermo Fisher director of marketing, Trace Elemental Analysis. “Few things affect quality of life more than food quality, and we’re resolutely committed to providing food scientists with an extremely wide range of the best-possible measurement tools.” Thermo Fisher Scientific Contact info and more items like this at wf.net.au/S583

These systems can be used for the measurement of various optical properties such as reflection, transmission, colour and coating thickness of transparent samples and coatings across a wide

TESTING & INGREDIENTS

range of industries and at every stage of the production process. The combination of polychromator technologies with good optics and fast, low-noise electronics provides the foundation for maximum sensitivity, linearity and a high dynamic range. The spectrometers are suitable for use where speed, sturdiness, reliability and performance are required, such as for complex, fast measurements in quality and process inspection in architectural and automotive glass production or in the plastics, coating and solar energy industries. The spectrometers contain PGS polychromators, enabling higher resolution across the wavelength range. Further benefits include: long service life of the light sources in the NIR; less noise; good linearity; the use of modern communication interfaces; and reduced power consumption which results in less thermal build-up and therefore higher stability. Most versions are offered either as single or dual-beam systems. Carl Zeiss Pty Ltd Contact info and more items like this at wf.net.au/S682

Collapsible sample bags Collecting water or other liquids for transport and analysis can present a number of problems. Hard plastic containers such as specimen jars are commonly used. However, these take up lots of space prior to use, making them difficult to store and transport. After use they can also present problems with disposal, taking up valuable waste capacity. An alternative to these containers are Stand Up Sample Bags. They store flat until ready for use, when the gusseted bottom flattens out, allowing the bag to stand up without the need for a rack or holder.

TESTING & INGREDIENTS

After the sample has been tested, the bags can then be collapsed for disposal, taking up far less space. Stand Up Bags are sterilised and are available in a selection of sizes ranging from 100 mL to over 2 L. Australasian Medical & Scientific Ltd Contact info and more items like this at wf.net.au/T128

Proteins for Greek-style yoghurt The specialist equipment usually required to produce Greek-style yoghurts, and the low yields per kilogram of milk used, can be barriers to entry into this market. Arla Foods Ingredients’ range of Nutrilac proteins can help manufacturers to enter the Greek-style yoghurt category without investing in a new processing line, and with reduced levels of wastage. Nutrilac proteins are designed to be used in conjunction with Arla Foods Ingredients’ Quick process - a manufacturing technique that eliminates the need for the whey separation step associated with traditional Greek

TESTING & INGREDIENTS

yoghurt making. This means users do not need to purchase separation equipment to make Greek-style yoghurt and can use their existing yoghurt-making machinery. The company claims its Quick process ensures that almost all of the milk used in the manufacturing process ends up in the final product. In traditional Greek yoghurt making, two-thirds of the milk is strained off as liquid whey and discarded to leave only the solid curds. This results in increased costs in terms of buying and storing extra milk and generates a waste stream that must be treated prior to disposal. Nutrilac protein solutions are available for a range of Greek-style yoghurt applications, including non-fat, low-fat, full-fat, long-life and drinking yoghurt. The company claims users can boost protein levels in Greek-style yoghurts to 10% by using Nutrilac solutions in combination with the Quick process. The proteins are manufactured from specially selected fractionated milk proteins, which means they are clean label and can be listed as ‘milk protein’ on packaging.

Digital sodium chloride refractometer Hanna Instruments has designed the HI 96821 digital sodium chloride refractometer to meet the requirements of the food industry. This optical instrument employs the measurement of the refractive index to determine sodium chloride concentration in aqueous solutions used in food preparation, particularly brine. The measurement of refractive index is simple and quick and provides the user an accepted method for NaCl analysis. Samples are measured after a simple user calibration with deionised or distilled water. Within seconds the instrument measures the refractive index of the sample. The meter uses automatic temperature compensation for accurate measurements and the dual-level LCD displays measurement and temperature readings simultaneously. The digital refractometer may eliminate the uncertainty associated with mechanical refractometers

and is portable. The instrument uses internationally recognised references for unit conversion and temperature compensation. It can display the measurement of NaCl concentration 4 different ways: g/100 g, g/100 mL, specific gravity and °Baumé. Temperature (in °C or °F) is displayed simultaneously with the measurement (on three of the ranges) on the large dual-level display along with icons for low power and other helpful message codes.

Functional flours and wheat aleurone Kampffmeyer Food Innovation presented functional flours and a grain specialty that improves the nutritional profiles of baked goods and other foods at the 2012 Health Ingredients Europe (HiE) exhibition. The company showcased two gluten-free functional flours from its Purafarin range, which extends its portfolio of clean-label binding systems for ready meals, soups and sauces. The company also presented Purafarin Hydrosoft, a functional flour that enhances the freshness and texture of baked goods and is claimed to achieve best results in the production of clean-label pizza. The company also demonstrated that the wheat aleurone ‘Vein of gold’ is a good source of dietary fibre, vitamins and minerals and can be used to enrich baked goods and other foods. The introduction of the two clean-label binding systems from corn and rice was prompted by the increasing demand for gluten-free variants from the food service sector, especially from companies who supply hospitals, schools and kindergartens. For dough processing, the wheat-based flour PurafarinHydroSoft was developed to improve the freshness and quality of baked goods, giving bread and bread rolls a soft and juicy crumb. During industrial production of pizza dough in particular, this functional flour can substitute fat and additives, which are usually required to meet customer demands with regards to texture.

With the functional flour, the dough becomes soft, fluffy and juicy and is characterised by a short bite with no chewiness or crumb flaking. According to the company, trials have shown that these properties can be maintained even after several months of refrigerated storage. The flour is manufactured with four basic baking ingredients: flour, water, salt and yeast. Since Vein of gold consists of the most nutritious fraction of the wheat grain, it provides all kind of baked goods, as well as foods such as pasta and breakfast cereals, with an improved nutritional profile.
