Letter from the Mayoress of Córdoba
The dish has managed to survive all the different periods in the history of our city, from the Romans who made it without tomatoes, until today. This quality of permanence is also a characteristic of Córdoba, which, like its most emblematic dish, strives to maintain its role as a place where all peoples and cultures of the world can be found, and where dialogue and compromise reign. It should be highlighted that besides being an ancient dish, salmorejo is made from simple ingredients, so making it affordable for rich and poor alike. This has united all the social classes around a common food that has been enjoyed in our lands for generations, In this book we delve deep into salmorejo, both as a

almorejo, timeless, ancient, complete and Cรณrdoban is one of the shining lights of Cรณrdoban gastronomy. Son of breads and oils, cereal and olives, fruits of the Cordoban lands, child of ancient garlic and of cheerful tomatoes which journeyed from beyond the
Atlantic to give salmorejo its colour. Needy for salt of the earth and good vinegar. Fruit of the most excellent products from the enveloping agricultural land, its career has been triumphant; from modest beginnings as a substantial dish served in homes and simple and exclusive restaurants, it has risen to become a symbol of the city itself. From nourishing dish to emblem, and from simple beginnings to a now, it has been a long journey to the great kitchens, where food gurus debate over which oil or tomatoes are best, or which is the best way to present it. Maybe neither salmorejo nor Cรณrdoba were aware of its great possibilities until the 21st century, when we began to value our traditional dishes - not just for what they are, but also for what they tell us about ourselves, our history and the dishes made by our ancestors. Years ago, every house on Cรณrdoba had a mother who made salmorejo, this universal salmorejo which represents one of the greatest dishes in the history of Andalusian gastronomy - and which could also be among the greatest in the future. Indeed, whether presented as a homemade dish or restaurant delicacy, salmorejo will always be what it is - a tasty, smooth dish, a main course or sauce, creamy soup or refreshing drink on torrid summer days. And above all, it will always be ours, unique, fruit of a land that has given this dish its family name and which has found something more than welcome - it has found its place. Ours, yours, a great dish - salmorejo from Cรณrdoba

MESSAGE FROM THE ACADEMIC DIRECTOR ON THE EXTRA VIRGIN OLIVE OIL SYMPOSIUM The Salmorejo Symposium related to the analysis of extra virgin olive oil was a huge success thanks to the participation of the public, professionals and chefs. The Guild and the Salmorejo Symposium are extremely grateful for the initiative of the Miguel Cabezas, President of the Grupo Cabezas Romero for having initiated this cycle of symposia. However, because this was at the start of the symposium, data and papers had not yet been thoroughly collated as they were for the latter participants. Despite this, we must thank Salvador Cubero, Alejandro Ibáñez and Manuel Heredia, President of the Association of Olive Mills, for their participation. Among the chefs who prepared tasting samples, were: Timoteo Gutiérrez, Kisko García, Antonio López, Juan Pedro Secaduras, Zahira Ortega, Juan José Ruiz Guzmán Vega and Matías Vega. In the presentation of the Symposium as Academic Director, I highlighted that the main aim of this symposium was to «enhance salmorejo as the national dish of Córdoba, a dish that besides being of tremendous tourist value is key for us in Córdoba because it contains natural ingredients from our land - like cereals, olive oil, vegetables and vinegars. It is a real prototype of the Mediterranean diet that was recently considered by the UNESCO an Intangible Cultural Heritage of Humanity. Salmorejo is part of our roots, it is intrinsically linked to our geography and our history, but also, and above all, it is the dish of Córdoba and that Córdobans should believe in because we enjoy and appreciate good cuisine.» Almudena Villegas, Academic Director

varieties), all grown in the Guadalquivir Valley, Córdoba. Morphological analyses were carried out to categorise them according to shape, size, weight, and colour according to the methodology developed by the International Plant Genetic Resources Institute (IPGRI), and physicochemical analyses were carried out to determine the free acidity content, pH, soluble solids expressed as ºBrix, index of ripeness and percentage of juice, following official analysis methods. From the results obtained a data sheet was drawn up for each variety.
owadays consumers are ever more demanding regarding the quality of food, expecting it to be not only healthy and nutritious but also flavoursome. That is why a sensory analysis is important, since it offers a unique method of finding out how consumers view and rate consumer products. Sensory analysis is the assessment of a food by means of the senses (ISO, 5492: 2008). From childhood people accept or reject food according to the sensations aroused by its appearance and smell, and/or when eating it, (colour, texture, aromas, spiciness etc.). In order to get accurate results when carrying out an analysis, strict conditions are followed concerning the participants who carry out the analysis (tasters), the coordinator, the place where the analysis is done (tasting rooms and meeting rooms), the sample preparation area - including the laboratory and kitchen - and records of when the analysis was carried out, the time, number of analyses, recipients used for tasting, tasting techniques and samples. A sensory evaluation using descriptive methods was carried out on four varieties of tomato (Pear tomato, vine tomato and the Caramba and Anairis

Results Figures 1 to 4 present the sensory analysis results, morphological data and physicochemical data of the four varieties of tomatoes studied.
The global physico-chemical analysis showed that the four tomato varieties have a pH of between 4 and 5, a soluble solid (SS) content of between 4 and 6, a titratable acidity (TA) of between 0.3 and 0.5, an index of ripeness that varies between 11 to 15 and a juice percentage of between 40-50%. Aguayo and Artés (2004) consider that for a fresh tomato to have optimal aroma and taste, it must have a soluble solid content of between 4 and 6 º Brix and a pH of between 4 and 5. Baldwin et al. (2008) consider that the relationship between SS and acidity is a good indicator of the taste and aroma of tomatoes. Elsa Bosquez (2009) considers that high values of ºBrix and acidity content correspond to tastier tomatoes. Thus, in our work the Caramba tomato, which has the highest ºBrix and titratable acidity content, is the one with the highest sweet fruit olfactory notes ■
The overall sensory analysis of the results found that each variety corresponds to a different gustatory-olfactory profile. The Pear variety has a medium intensity aroma with fruity, green notes (grass and radish), and a sweet, very tasty, slightly spicy flavour. The Vine variety has a mediumintensity odour/aroma with green notes (tomato plant and tomato leaf) and very flavoursome taste. The Anairis variety has a medium-high intensity aroma with sweet fruit and green (grass) notes, slightly acidic taste and flavoursome. The Caramba variety has a high-intensity odour/aroma of sweet fruit and radish; slightly acid, spicy, flavoursome. In addition, the four varieties present aromas of overripe fruit that may sometimes smell bitter or of sulfhydric acid (rotten egg smell). It must be emphasised that the four varieties studied each presented an intense flavour due to the high monosodium glutamate content found in significant amounts in ripe tomatoes. All the varieties studied are red and bright with a firm, crunchy, juicy texture. Of all them, the Caramba variety is the firmest, while the skin is easily separated from the pulp in the Pear and Anairis varieties. From the morphological analysis, it was observed that all the varieties have a red fruit outer colour and are mainly round, except for the Pear variety which is oblong. Regarding size, Anairis is the largest with an average diametre of 7.8 mm. and an average fruit weight of 190.8 g. The smallest is the Vine variety with an average diametre of 6 mm and average weight of 100.4 g.

Two varieties of tomato (Anairis and Rosa) grown in the Guadalquivir Valley orchards, Córdoba are characterised. For each variety samples are taken from three different zones of the orchard (replicated) that are analysed in duplicate. Each replicate consists of a minimum of 10 mature fruits from five branches. The fruits are taken from the second and third branch of each plant. In total, 18 samples are analysed: 2

horticultural products (oranges, tomatoes, lettuce, aubergine etc.). This is why a morphological, sensorial and physicalchemistry study of the main varieties of cultivated tomatoes has been carried out in this area. There are numerous factors that determine taste in the tomato: the variety, plant nutrition, degree of ripeness of fruit, post-harvest handling and content in sugars (mainly fructose and glucose), the latter being the one that most influences consumer choice (Baldwin, 2004). Numerous investigations demonstrate that tomatoes harvested before ripening are less sweet, more acidic and have less flavour than the fruits that have reached the correct point of maturity.

Methods Morphological analysis The results of the sensory analysis indicate that there are significant differences in the intensity of smell and aroma and texture; Anairis presents sweet fruit, green olfactory notes, while Rosa is characterised by green fruit and tomato leaf notes
The weight, shape, size, homogeneity of size, length, width, outer colour and intensity of outer colour are determined. The methodology followed is that developed by the International Plant Genetic Resources Institute (IPGRI). Sensory analysis The sensory characterisation was carried out with the analytical panel of the UCO (GrupoSens-AGR020) following the sensory profile method (ISO 13299: 2003). This technique identifies and quantifies the different sensorial attributes according to the order of appearance. We evaluate 18 descriptors for the sensory characterisation of tomatoes: 8 descriptors for the odour / aroma (overall intensity, fruitiness, sweet fruit notes, green notes; tomato leaf notes; chemical; sour and faecal); 3 descriptors for the basic flavours: sweet, sour and tasty; 2 for the trigeminal sensations: (refreshing and astringent) and 5 for texture (firmness, crunchiness, mustiness, flouriness and separation of skin from pulp).
Regarding the physical-chemical analysis, it should be noted that the two varieties have a pH of between 4 and 4.5, a soluble solids (SS) content of between 5 and 6, a titratable acidity (TA) of between 0.3 and 0.5, a maturity index ranging from 12 to 19 and a juice percentage of between 4060%, the only significant differences are in the luminosity parameter, as the Rosa variety is brighter than the Anairis variety. ■
Physicochemical analysis The colour, juice percentage, the pH, lycopene content, free acidity and soluble solids expressed as ° Brix are determined. The maturity index is expressed as a relationship between the Brix grades and the acid index. The methods used are described by García-Méndez et al. (2009), and Periago et al. (2001). RESULTS AND DISCUSSION The results of the morphological, sensorial and physicalchemical analysis are presented in Figures 1 and 2. From the morphological analysis it was observed that there are significant differences between the Anairis variety and the Rosa variety for the descriptors of weight, equatorial diametre and thickness of the pericarp. The Rosa variety is larger than the Anairis variety. The morphological descriptors evaluated both varieties as having a round shape, a reddish pericarp flesh colour, white heart, a round cross section shape and light yellow, ovate-shaped seeds. In addition, the size of the Anairis fruit is very homogeneous, with a red outer colour and green shoulders, while the Rosa variety is large, not uniform and with a pink outer colour.

Celsus all the properties of garlic are good, even its smell, because of its power to reinvigorate lethargic people. In the poem Moretum, Virgil exalts life in the countryside and gives a recipe for ‘moretum’, the energy-giving countryman’s breakfast made from herbs, cheese, salt, oil, vinegar and garlic ground together in a mortar. The poet Martial also defended garlic, claiming it was capable of arousing an elderly man’s passion. Roman soldiers were country folk by origin and planted garlic wherever they went, thus spreading it throughout the Roman Empire. The Roman army’s food supplies included garlic since it was easy to carry and kept legionnaires, with limited access to clean drinking water, free of intestinal parasites.
During the Middle Ages, vampires and those affected by porphyria were the only ones who could not tolerate garlic. Its popularity rose even more when it was discovered to be a powerful antidote against the plague that ravaged Europe. Centuries late, the analyses carried out on its medicinal properties proved that garlic is a natural antibiotic.

Around 1500 BC, the Ebers Papyrus mentions garlic in twenty-two recipes said to combat diseases such as infections, headaches, pharyngitis, physical fatigue and some tumours.
Nowadays, although garlic is a universal condiment and hugely popular in China, India and the Mediterranean and Spanish-speaking countries, in Britain it does not share this popularity - even though pirates used it as a remedy long before the Vikings. Pliny recommended garlic mixed with wine for shrew bites, while Mohammed suggested garlic as a remedy for snake or scorpion bites. A modern Jewish saying claims that: “With three nickels you will enter the subway, but only garlic will provide you with a seat.”
Without garlic, our gastronomy would be completely different; we would not be able to enjoy its pungency and flavour-enhancing properties, nor benefit from garlic’s curative powers. So, on an olfactory level, perhaps we should be more tolerant towards allicin, the component responsible for its medicinal effects and its distinctive smell ■
There have always been aliophiles and aliophobes, and its characteristic smell “that does not leave you”, was very much appreciated by the working classes, due to its energising and healing properties. However, Don Quixote warns Sancho Panza not to eat garlic or onions “because they will betray your villainy.” The biggest detractors of garlic were found in England in the sixteenth century when, long before Victoria Beckham, garlic was already considered most unpleasant “for beautiful ladies who prefer sweet breath followed by soft words,” In 14th century Spain, Alfonso XI king of Castile proclaimed that no gentleman who had eaten garlic could approach him for at least a month. An indirect consequence of the upper classes’ repulsion of garlic is found in the nineteenth century when Queen Margarita - who loathed it ordered a garlic-free pizza, so creating the ‘Margarita’ pizza.

France is perhaps the only country that has been carrying out projects aimed at obtaining certified garlic seeds for more than thirty years. For some time now in California, a plan for the improvement and selection of garlic for seed has been under development, using original French material among others. In Spain, Dr Peña Iglesias developed the only project aimed at obtaining a commercial variety of the Cuenca Red garlic, although recently some private companies have obtained varieties of certified garlic. The French commercial varieties were grown in Spain after a comparison in the early eighties was undertaken in Cuenca, Granada and Córdoba between the French and native Spanish varieties.

Description of garlic varieties
Description of the varieties and ecotypes used 1. VARIETIES FROM CERTIFIED SEEDS
BASIC I: The name was given to this variety of garlic after work done in the early years on a “variety” of WHITE TYPE garlic by the Californian company, BASIC CO. The plants are vigorous in good fertile soil conditions that have an adequate water supply; open plants with young, upright leaves that can reach 75 cm. Leaves are large broad, and flat, and can sprout 12-14 leaves. The pseudo stem is thick, (30 mm in diametre, measured at the base). The bulb is large, white, irregular shaped, conical with large cloves in the periphery and usually with small, flattened cloves in the centre. It does not develop a floral stalk. Planting time is around the garlic sowing time of local red garlic (mid-November to midDecember in Córdoba and Granada). Its cycle is a few days shorter than the Cuenca red type. It is sensitive to rust and penicillium. It has not been shown sensitive to white spot. It does not have a commercial varietal certificate of origin. The marketing company controls quality and homogeneity and guarantees it is fit for human consumption.
The commercial varieties of garlic, taken from massal selections and in vitro multiplication cultures of meristems, have been subjected to rigorous sanitary and quality controls regarding the production process. Certified seeds of a certain garlic variety formally guarantee: Varietal purity (minimum, 99%) Maximum percentage of bulbs sprouted or altered (maximum, 3%) Maximum percentages tolerated during cultivation controls are: Virus free (maximum, 1%) White-rot free (maximum, 1%) Nematode free (0% of our laboratory analysis) In the annual works developed during the 1983 - 199697 seasons, the varieties included are described below in alphabetical order.
BASIC II: The name was given to this variety of garlic after work done in the early years on a variety of PINK TYPE garlic by the Californian company, BASIC CO. The plants are vigorous, open and plume-shaped. The leaves are large, white and curled, with up to 13-14 leaves. The bulb is large, white, conical-ovoid with a tendency to produce numerous, medium-small sized cloves, with a slightly pink tunic. No floral stalk. Planting time is after the garlic sowing time of the Cuenca Red garlic (beginning of December to beginning of January), although it can be planted before, at the same time as Cuenca Red) without budding problems. It has a long latency period which allows a good conservation. Its cycle is longer than that of the local Red ecotypes by about 20 days. Sensitive to rust. The marketing company controls quality and homogeneity and guarantees it is fit for human consumption. CRISTO: Certified PINK TYPE variety. Obtained by INRA and marketed since 1990 by TOP SEMENCE (U.C.C.S.). The structure of the plant is reminiscent of Chinchón garlic, but the plants are much more vigorous. It can develop up to 1415 wide, long, curled, dark green leaves.

leaves at the base and no floral stalk. Short cycle (12-15 days shorter than the CUENCA RED). Large, conical, irregularshaped bulb, with yellowish, purple-veined tunic. Sensitive to rust. Obtained by INRA in 1975.
An erect, open plant with horizontal base leaves, reaching 80-85 cm high and 90-95 cm wide. It has a long period of latency - so increasing conservation time - and a long cycle, making it commercially unsuitable for the national market, especially the Andalusian market where precocity is of great importance. The bulb is conical with white-skinned cloves. It produces many cloves, so care must be taken when adding nitrogen to the crop, both with the doses and when it is added. No floral stalk and sensitive to rust. Can be planted from early December to late January and is ready to harvest in early July.
MESSIDRôME: WHITE TYPE certified garlic With very similar characteristics THERMIDRôME, these two were the first virus-free varieties commercialised on the garlic seed market. Obtained by INRA in 1971. From the BLANC DE LA DRÔME garlic variety. Very uniform vigorous semi-upright plants, with horizontal leaves at the base reaching up to 90-95 cm when fully developed. Intense green leaves, lighter in colour than GERMIDOR. Develops 14-15 long, 36-38 mm wide leaves and has a thick pseudostem (22-25 mm diametre at the base). No floral stalk. Cycle is between CUENCA RED and GERMIDOR. Large conical bulb with white-yellowish tunic. Very thick peripheral cloves, with large or medium-sized, low weight central cloves. Unsuitable for planting.
GERMIDOR: It is a certified WHITE TYPE garlic variety from France. It comes from the CADOURS VIOLET garlic ecotype. It looks like a purple garlic, although it behaves like a white garlic. Vigorous plants with 16-17 intense green, wide leaves of normal length (40-44 mm wide and 58-60 cm long). When fully developed, the plants reach 85 cm in height, with a 2325 mm pseudostem diametre at the base. Erect, with open

full maturity, the plants reach 80-85 cm high with a thick pseudostem (23-25 mm diametre at the base). The bulb is largish, conical with white-pink skin. Extremely sensitive to rust. At present, this variety has been displaced by CRISTO. SPRINT: The most recent type to reach the market, it is a certified variety of Red garlic and bred by TOP SEMENCE of France, in 1991: Variety obtained by INRA in collaboration with the marketing company. Extremely precocious, displaying vigorous sprouting - the first six leaves develop quickly. The plants have a peculiar structure, similar to ‘Indian’ or ‘Chinese’ garlic (also called TAIWAN), and with a thick, 22-24 mm wide, tall, 30-32 cm pseudostem. Erect with arching leaves.

2. ECOTYPES As previously mentioned, the main difficulty with these ecotypes is their lack of homogeneity and total lack of control by the authorities in terms of the health and quality of garlic grown for seed.
Currently, the seeds used most come from garlic populations with similar characteristics, more or less identical in terms of morphology, cycle, behaviour, etc., coming from a given geographical area, in other words, certain garlic ecotypes.
Healthy plants are vigorous, erect with 12 or more large, wide, flat leaves. The bulb is large, white, globe-conical shaped, with large cloves on the periphery and many small cloves (often wrapped in the same skin and so appearing as a single clove) in the centre. No floral stalk and best for planting at the beginning of November- mid-December. It has a relatively short latency period, with spontaneous budding of garlic for seed in mid- November. The cycle is a few days shorter than Cuenca Red of, although usually one or two weeks prior to the Reds. The plant is sensitive to rust. Currently it does not have much commercial value and is sold on the local market near production areas.
Garlic ecotypes are often named according to the area from which they come and the type of garlic. The most important from the point of view of trade, are the CUENCA RED GARLIC, (PEDROÑERAS PURPLE), CÓRDOBA RED, GRANADA RED, CUENCA WHITE, RONDA WHITE, VALLELLO WHITE, VALLADOLID WHITE and JAEN WHITE. Studies comparing commercial varieties and ecotypes have been carried out. Description of garlic ecotypes CUENCA WHITE: This ecotype has been grown in the garlicgrowing regions of Cuenca for many years.
LOMAGNE WHITE: Ecotype from France (Lomagne), which develops vigorous, erect plants reaching 70 cm high with 14-16 large, straight, broad, flat, young leaves. The bulb is large, white, globe-conical shaped, with large cloves on the periphery, and many small (often wrapped in the same skin and so appearing as a single clove) in the centre. No floral stalk and best for planting between mid-November and late December, matures at the same time (or a few days before) the local Red ecotypes. It is sensitive to rust.
The main difficulty with these ecotypes is their lack of homogeneity and total lack of control by the authorities in terms of the health and quality of garlic grown for seed. Healthy plants are vigorous, and can reach the 85-90 cm in height. It develops 13-15 long, flat leaves, distinguished by their length and width (64-66 cm long and 35-40 mm wide), with a short pseudostem of 22-24 mm diametre at the base. No floral stem. The plant is moderately sensitive to rust. The
RONDA WHITE: Ecotype from the province of Malaga, now cultivated frequently In Córdoba. Moderate to good vigour, erect, reaching 85-90cm high with a thick pseudostem, although smaller than the French varieties (20-22 mm). Develops 11-13 long, wide leaves (65-68 cm and 33-37 mm respectively). No floral stem. Large, conical bulb, with white or whitish-yellow tunic. The cycle is about 10 days shorter than CUENCA RED. Sensitive to rust.
cycle is shorter than the CUENCA RED by about 10-15 days. It has a large ovoid bulb, with white tunic. BLANCO DE CHINCHÓN (FINO DE CHINCHÓN): Pink ecotype from Ajofrín (Toledo), grown in Chinchón and the surrounding areas for many years. Vigorous, erect, reaching 74- 80 cm high, with a thick pseudostem (21-23 mm diametre at the base) and developing 12-14 dark green, curled leaves shaped like a candlestick, of about 60 cm long

Four varieties of garlic (Early white, Early purple, White and
The aim of this work is to contribute to a better knowledge of garlic for use in the cuisine of Córdoba. To that end, a morphological and sensory characterisation of the main cultivated varieties in Montalbán (Córdoba) was carried out. This municipality is located in the south of Córdoba, where the main economic activity is the cultivation of garlic. Garlic, (Allium sativum L.) is a vegetable commonly used in Mediterranean cuisine, above all for its distinctive sensory characteristics. Depending on the variety, garlic has a strong and somewhat spicy flavour. In fresh garlic, it tastes spicy because of an enzymatic reaction when the tissue is broken by cutting or chewing, releasing a series of sulfuric compounds such as allicin, which is mainly responsible for garlic’s characteristic aroma and flavour. From a sensory point of view, spiciness is defined according to three properties: time to detection, stimulation and persistence in the mouth. In garlic, this sensation is different depending on whether it is prepared with a water or oil base.
Red) grown in Montalbán (Córdoba) were characterised. From each variety, a representative sample was taken and analysed in triplicate. Sensory analysis The sensory characterisation was carried out with the UCO analytical panel (GrupoSens-AGR020) following the sensory profile method (ISO 13299: 2003, Coste, 2010). This technique identifies and quantifies the different sensory attributes according to their order of appearance. 15 sensorial attributes are valued on a 10 cm non-structure scale anchored at ends: 7 for odour / aroma (overall strength, fruitiness /acidity, vegetable / onion / chive, aromatic herbs, mustiness, synthetic rubber/India rubber, burnt and others); 2 basic flavours (sweet and bitter), 2 trigeminal sensations (pungency and spiciness), 3 texture (firmness, crunchiness and moistness) and persistence.

add flavour and has become part of our diet. Production and consumption Garlic is produced and consumed almost worldwide. Spain is the 6th producer of garlic globally, but since cultivation was significantly reduced, it has fallen in recent rankings. Our garlic But not everything is about volume of production - Spanish garlic is a quality product, in great demand both at home and abroad. This popularity has given rise to so-called ‘Spanish garlic’ in order to differentiate it from other types (especially from the Chinese type currently flooding our markets). In Spain, Andalusia is the second producer nationally, producing more than a third of the global national production. 75% of Andalusian production is from Montalbán in Córdoba. Per capita, garlic consumption is around 1.4 kg/inhabitant/year (MARM, 2008), which should be qualified obviously when considering regional and cultural differences and differences in personal taste.

Garlic was introduced into Britain by the Romans. During the Dark Ages, it was probably only cultivated in the orchards of monasteries. In the Middle Ages, due to the Anglo-Saxon interest in herbs and plant species, garlic became popular and was known as ‘molu’, in memory of the plant mentioned in Homer’s Odyssey Book X, and which was given by Argeiphontes to protect against the powers of Circe.

in other foods, garlic presents more than 30 extremely beneficial compounds in small quantities. Among these components, the best known, most studied and principal component, is alliin derived from the amino acid, cysteine. In contact with air, this compound transforms aliinae into allicin, responsible for the aroma of garlic. Allicin itself and its derivatives provide some of the health giving properties of garlic. Garlic contains other beneficial chemical compounds, fructanos, fructose polymers attached to a glucose molecule. These compounds are beneficial because they escape the digestive process and absorption by the small intestine. Instead, they go directly to the colon where they are selectively fermented by bifidocterias and lactobaillus and inhibit the development of bacteria like Escherichia coli and Clostridium perfringens. Fermentation produces shortchain fatty acids like acetate and propionate, which can lower cholesterol and influence intestinal mucosa.

observation and popular knowledge. In other cases, scientific observation has corroborated some of its effects, as did Louis Pasteur who described garlic’s antibacterial effects. Garlic is most effective when 3 cloves of garlic a day or garlic oil (not for all therapies) are consumed. There also appears to be a medium-long term effect when consumed habitually. The Federal Health Agency in Germany says that a 4g daily consumption of raw garlic or 8 mg of garlic essential oil controls cholesterol and prevents other cardiovascular diseases. Many of these properties have been scientifically investigated and the new trend of evidence-based medicine has found the following:

Other ways of eating garlic 1. Raw: chew 1-3 cloves in the morning. May produce body odour and the therapeutic effects of active principles are not controlled.
Garlic is safe during pregnancy, but should be avoided in excess due to the risk of bleeding. In addition, in experimental models garlic provokes difficult childbirth, increase of lactation period, odorous milk and reduction in infant intake.
2. Garlic extract: in capsule or pearls. Does not cause body odour. 600 to 900mg daily is the recommended dose for therapeutic effects.
It should be used with caution when combined with an antihypertensive, statins, antiretrovirals (saquinavir, ritonavir), hypoglycaemic agents or antithyroid drugs.
3. Decoction of garlic cloves: boil one garlic head in a litre of water for five minutes. Drink three cups daily. Some of the properties are lost but it does not produce bad breath.
Cases of bleeding have been reported with concurrent use of garlic with ginkgo balboa or with saw palmetto, alfalfa, American ginseng, anise, arnica, aspen bark, cranberry, birch, boldo, cat’s claw, celery, chamomile, chaparral, clove, coleus, fish oil, flaxseed, ginger, grapefruit, green tea, horse chestnut, radish, onion, papain, parsley, passionflower, poplar, propolis, rhizo mushroom, Siberian ginseng, sweet clover, rue, Vitamin E, white willow, wild carrot, wild lettuce, willow, wintergreen and cassava.
4. Maceration in vinegar: causes body odour and active principles content is lower. Nevertheless, used over extended periods of time there may be an accumulative effect. 5. Black garlic: new to the West although traditional in the East. It has the advantage that pungency is totally eliminated and conservation is high. Some studies state an increase of up to 10 times in antioxidant capacity.
Harmful side effects and contraindications
By modifying blood pressure, the effects can inadvertently increase when combined with arnica, cranberry, eucalyptus, eucalyptus oil, linseed / linseed oil, ginger, ginkgo, mistletoe or vinca.
Like all active ingredient or medicine, the beneficial effects of garlic may be tarnished by harmful side effects. Some are just simple questions of social norms; others derive precisely from the interactions that may occur when eaten with other foods or medicines that have similar effects to those of garlic.
Diabetics should be careful when combining garlic with American ginseng-based herbs, blueberry, fish oil, chestnut seed extract (HCSE), rosemary, Siberian ginseng, nettle and white horehound. â–
Commonly reported side effects are bad breath, odour on skin and mucous membranes. Less frequently, garlic may cause allergic reactions, rashes or burns to the skin, dizziness, diaphoresis, headache, itching, fever, chills, asthma attacks, nasal congestion, mouth burns, abdominal pain or a bloated feeling, lack of appetite, meteorism, nausea, vomiting, gastric disorders, changes in intestinal flora, diarrhoea or constipation. Oligopermia (low sperm count) has also been noted in rats, but not in humans. Bleeding is a potentially serious side effect in cases such as spontaneous post-operative bleeding, platelet dysfunction or abnormal fibrinolysis, being more frequent in patients with an hemorrhagic tendency or who take oral anticoagulants(acenocoumarin), aspirin and other antiplatelet agents (clopidogrel) or anti-inflammatory drugs such as ibuprofen or naproxen. Caution is advised for people with diabetes or hypoglycaemia and those using drugs, herbs, or hypoglycaemic supplements.

H
aute cuisine ignores no food however simple it may be. Moreover, it could be argued that basic products like bread, oil and vegetables - simple only in appearance - are precisely the basis of good gastronomy.
Mediterranean and Atlantic voyages who wanted a food that had been part of their diet for many generations. It is difficult for an historian to think about the history of man without mentioning bread and that leavened flours are filling, can take many forms and make breads that are crisp, soft or suitable for fillings. Bread can be simple and elegant, white and sophisticated or full of aroma and flavour, combining well with other cereals and even ingredients like nuts, olives and vegetables. Whatever shape or form, bread has been a man’s constant companion - giving both sustenance and pleasure. It has played a transcendental role in human history, from sustainer and provider of pleasure, to catalyst of progress in the technological development of other products and foods.
Bread has been the great food of the Mediterranean, often making the difference between being hungry or not and has been a staple from Neolithic times to the present. Breadmaking has also given rise to a great development in technology: special closed ovens designed for better baking and also to gaining a deeper knowledge of the fermentation processes - which were not easy to control accurately. From the management of flour mills and discovering the best time to harvest cereals - to knowledge garnered form agronomy, technology and engineering - all facets have been actively involved in the development of a product that we call ‘simple’ and that, nevertheless, has been part of our diet for many years. Although bread is considered basic, perhaps it deserves more recognition and a more detailed study of how it has helped us to progress.
Since the times of the ancient world to the twentieth century, different breads reflected the owners of the tables they were served at: the upper classes at the best tables served white, refined bread, while the poorest ate ‘inferior’ brown breads - dark, solid, high in fibre and much healthier - although they were not considered so at the time. Today nutritionists recommend precisely those brown breads which had been considered second class years ago.
In fact, humans have been eating bread for more than six thousand years, perhaps making it therefore one of man’s best allies - and not just white bread from wheat, but also brown bread with all its fibre and nutrients intact. The bread eaten long ago was richer and had more complex flavours, more solid and quite different in texture from today’s light, airy bread. There were also breads which were like unsweetened biscuits that had been baked twice (biscoctos) in order to remove any moisture and thus avoid mould. This bread was taken on boats that sailed through the Mediterranean - and on the ships Columbus took on his journey to America. The loaves were lightly fermented, thin, crisp and almost dry, and were given to sailors on
n ancient Rome bread was one of the most important parts of the people’s diet. Every morning, before dawn, hundreds of ovens were lit and bakeries opened which sold cheap, government-subsidised bread - sometimes even given away free. Panem et circenses, or ‘bread and games’, designed to keep the people happy, is considered even today necessary for peaceful governance. The most sought-after and expensive breads were white, refined, had a thin crust, made with the best flour - and only within reach of the rich and powerful.

It is said that the first bread, and fermentation of dough, was invented in Egypt, and was due to a an accidental discovery around 3000 BC, when a young apprentice baker neglected his duties and left the dough exposed to air longer than usual - which made the damp surface of the bread ferment. As an experiment, the young man put the dough in the oven and saw that it greatly increased in volume. This produced the first soft, spongy bread with a crisp, golden crust - tasty and easy to digest. The fermentation of dough had been accidentally discovered. It would be the Egyptians of the IV dynasty (2613- 2494 BC) in Cheops, Khafre and Mycerinus that developed breadmaking techniques, invented the oven Carbonized loaf of bread found in Pompei, AD 79

The only remedies against this terrible disease were prayers and charms, but they did not cure; the only ‘cure’ was to do the pilgrimage of the Way of Saint James. Pilgrims underwent a series of miraculous healings when they came before the apostle, but fell ill again when they returned to their country of origin. However, if they returned once more they were again healed. The reason sufferers were cured was because those suffering from the illness, in the more than 400 hospitals of the Order of San Antonio in the south of Spain, were given wheat bread, while in northern and central Europe they ate rye bread - and rye sometimes contained the ergot fungus, the cause of the feared Infernal Fire disease. The presence of the fungus in rye bread leads to ergot gangrenous, a vascular disease attributed to prolonged consumption of contaminated rye bread. These ‘infallible’ miraculous healings associated with the Apostle James were part of a push to consolidate the power of St James and the Order of Saint Anthony in Europe - and added to the religious symbolism that bread had always had.

THE SITUATION IN SPAIN
N
ationally the bread market has undergone important changes in the last few decades, one of those being the change in breadmaking from an artisan process to a fully industrialised one. Retailing has also changed, from sales of bread in traditional bakeries to outlets in supermarkets or franchises.
Faced with this situation, it is necessary to transform the sector and develop new products to adapt to new tastes and trends - such as making breads which are low in salt and fat have no additives. Another trend is the production of highend breads, with ecological ingredients and using different cereals wheat (rye, corn, sorghum, etc.). The aim, therefore, is to create a new market and maintain, or even enhance,
At present, each person in Spain consumes on average 46 kg of bread a year, which means an outlay of more than € 110.
the traditional bread market. CONSUMPTION BY VARIETY
The current economic crisis has affected all sectors including the food sector. Within this broad sector, bakers have also been affected even though bread is a staple in our diet.
The most popular varieties consumed in Spain are fresh or frozen breads. From May 2012 to April 2013 these breads accounted for 84.2% of the market, an increase of 1.5%
There are other causes contributing to this crisis including the high price of supplies, competition between producers, higher taxes and the myth that bread is fattening, to name just a few.
compared to the same period the previous year. Sales of fresh bread rose by 14.3% and fresh bread without salt increased by 18.2%. The remaining 15.8% of bread consumed in the home is industrially-manufactured bread. In the past 12 months,
The rise in the price of raw materials is due to the pressure exerted by the prices at origin, due to massive purchases of grain to provoke shortages or gluts in a given market. This can lead to price increases which result in a reduction in purchasing - because for the customer, price, not quality is the most important.
sales have increased by 3.3%. According to study data, more than 4 of every 10 kilos of bread are bought from traditional bakeries and sales have remained almost stable.
Moreover, in our globalised world there are many competitors which combined with the current trend to decrease flour consumption means output in the sector is increasingly smaller.

CONSUMER PROFILES
Thus, per capita consumption stood at 36.12 kilograms per person per year, and the average amount spent on bread made up 5.75 percent of a household’s total food budget.
The profile of consumers with a high bread intake corresponds to that of a large family (more than 4 people).
With regard to the province of Córdoba, data are similar to those regarding the rest of Spain, including those of Andalusia. Baguettes are especially popular and are sold by large supermarket chains at a much lower price. This is regarded as unfair competition for the industrial baker, who cannot sell bread as cheaply since that is their only product. Supermarkets also use cheap bread to lure people to the shop in the hope that, once there, they spend money on more profitable items too.

Yeast Table 1 shows the composition of the main flours used in breadmaking. Included are soybeans, although this is a legume - and the type used in baking is not the one displayed but a defatted flour. In the table, therefore, soybean bread shows some of the highest values both in terms of calories, fat and other nutrients.
east does not provide any nutritional value as it is present in very small amounts in bread, but it does cause structural changes in flour due to the way it interacts with some of its constituents such as carbohydrates and proteins. Despite using nutrients to convert the constituents to the gases produced in fermentation, nutritional loss is about 5% for both proteins and carbohydrates, and can be considered negligible.
We can see how wheat flour, both white and wholemeal, present average values and are similar to other flours made from cereals. Oat flour has a high calorie content and a high number of nutrients. The lowest calorie content is in barley flour, which along with rye has the highest fibre content.
Flour Flour is the main ingredient, the most important and the most variable in composition, as much depends on the strain or type of cereal used, the degree of extraction and other factors in the breadmaking process.
Obviously, as we have seen, selection and genetic manipulation of plants for flour has produced variants and strains that may lead to substantial changes in nutritional composition, and despite this not usually being the aim, it may be a consequence, although we have no reliable data on these changes.

Carbohydrates As we said earlier, bread is made up mainly of flour diluted by the water added to the dough. Approximately 50 per cent of bread is made up of complex carbohydrates, which has put bread at the base of all food pyramids. The WHO, and virtually all public and private entities involved in nutrition, recommends that at least 50% of our daily calorie intake should come from complex carbohydrates. Bread along with other cereals, legumes and some tubers are the most abundant sources of this type of energy provider.
By seed variety, the lowest energy content is that of oat bread (interestingly with the highest calories when a flour), barley and maize which have a very high moisture content, around 50%, while in wheat it is usually below 40%. Also, we find low energy content in rye bread, although the water content is similar to that of wholemeal bread. Obviously, this difference in moisture has an impact on its energy content. The commercial forms of non-wholemeal breads are very similar to each other. However, depending on the type of
Glycaemic index
sliced bread, energy content may increase significantly.
White bread is used to measure the glycaemic index (GI) of other foods. It is assigned a value of 100. However, wholemeal varieties have a lower GI and are more suitable for diabetics.
Wholemeal breads have slightly lower energy content than others that contain less fibre. The benefits of these breads come not from the energy they can produce but from their fibre content. The varieties shown here will also give the

a decrease in moisture, and for fried bread, the change is
Resistant starch
also notable because of the incorporation of the fat used in
For its physical structure (starch) this compound should be easily digested, but it is not processed by human digestive enzymes (amylose). In bread, resistant starch increases (in amounts depending on the flour), because of the heating and cooling in the breadmaking process, which produces a gelling of the amylose (retrograded starch or resistant starch - Type III). The more times the dough is heated and cooled, the more retrograded starch is produced. Dietary fibre may also increase as bread gets older and loses moisture.
Milk breads and rolls have substantially greater energy contents because fats are added which increase the lipid content. Finally, the normal processes involved in breadmaking also
frying that partly replaces the water content, so the energy content can be double that of the original bread. The idea that the crumb provides more energy than the crust is not true - on the contrary, the energy value is less weight for weight because the crumb contains more gaseous components, so that per unit volume it weighs less. In addition, the crumb has higher moisture content than the crust. So the next time you eat bread remove the crust instead of the crumb. Another misconception about bread is that breadsticks are lower in calories - but the energy content of this type of product is around 400-450 kcal/100g, almost double that of the average loaf. When considering energy content, we need to remember the two factors previously mentioned, that the less moisture content there is the higher the energy content and the use of fats to improve the moulding process.
82
BREAD
Lipids Natural fat content in flour and bread is primarily polyunsaturated fat, more specifically linoleic acid, an essential fatty acid which accounts for more than 50% of the total fat content of white bread. Oleic acid accounts for just 10% of lipids; the Omega 3 content is low - (3%) and saturated fats amount to around 15% of the total fat. This profile, although not optimal, can be regarded as acceptable from a cardiovascular point of view.
The fat content of bread is usually low, around 2%, provided that the composition of the dough contains the basic ingredients (flour, water, salt and yeast). However, the use of animal fat or vegetable fat is becoming increasingly common in the making of certain varieties of bread in order to make it moister and spongier. This often occurs in some sweeter breads, some of which are in Table 2, like hamburger buns, milk loaves and some rolls. This increase in fat means an increase in calorie content as we also saw in the corresponding section.
Proteins The protein content of the bread is very high (6 -10%), since it is a food of plant origin. Using plants for food meant that people had an another source of protein in case the hunt failed or there was no access to animal protein - perhaps due to feudalism, famines, plagues, poverty, etc. In many developing countries, grain (wheat, corn, rice or millet) is the main source of protein for people. However, the quality of cereal protein, including bread, is not optimal given that the proportion of amino acids is not properly balanced according to our need for so-called ‘ideal protein’. Table 3 gives the amino acid content of some types of bread protein as a percentage of the total protein, and, in the last column, the percentage ideal for human development. As can be seen, of the proposed six amino acids (the amino acids of the two sulphurs, cysteine and methionine), only lysine is below the recommended intake in all varieties of bread and in virtually all the cereals used in breadmaking
Depending on the type of fat used, the nutritional effect may be different. Coconut or palm oils are often used which, although of vegetable origin, have a high saturated fatty acid content. Fortunately, because of consumer demand these types of fats are being substituting with olive oil or sunflower oil that could be better for cardiovascular health.

Gluten Gluten is composed mainly of gliadin and glutenin, proteins found in some grains and that confer elasticity (glutenin), adhesion and extensibility, (gliadin) and the retention capacity of carbon dioxide during fermentation, which makes the bread spongier.
Fortunately, in our diet we have legumes that can compensate for this lysine deficit. Legumes are deficient in sulphur so a diet combining cereals and legumes can provide good quality proteins. Glutamic acid, on the other hand, is the amino acid found
There are some people who are gluten intolerant (celiac disease), since these proteins cause intestinal mucosa deterioration which not only has an impact in the type of digestive problems, but can also cause a low absorption of nutrients.

non-communicable diseases such as cardiovascular disease, hypertension, and diabetes. This link between bread and obesity has become deep-rooted in our society, despite there being no scientific evidence to support the idea. However, recent studies undertaken by prestigious Spanish researchers contradict this. Perhaps the most prominent has been the research carried out by Professor Serra Majem’s team which, by means of a meta-study of publications in which bread consumption is related to body weight, concluded that only not does bread not cause obesity, but that regular consumption of bread (even better whole wheat), favours weight loss, the reduction of the fat around the waist and of body mass index. Similarly, in a study on schoolchildren, Professor Ortega’s team found that children who consume more bread were less overweight. Despite these scientific findings, the same cannot be applied to people on slimming diets, since it is often recommended to reduce bread intake. But Dr .Gomez Candela’s team found that weight loss is the same with or without bread in hypocaloric diets, but those who ate bread kept to the diet longer and had a greater feeling of satiety, which is why including bread in slimming diets is beneficial.

SENSORY ATTRIBUTES OF WHITE BREAD: TELERA FROM CÓRDOBA HORTENSIA GALÁN SOLDEVILLA, PILAR RUIZ PÉREZ-CACHO, JOSÉ CARLOS UCLÉS GÁLVEZ y MARÍA DE LA HABA RUIZ Sensory Studies Laboratory (AGR-020) Department of Food Science and Food Technology (University of Córdoba)
Bread: flour, yeast and water Water: water plays an important role in all chemical changes - biochemical and structural - that take place during kneading and baking. During kneading it participates in making up the structure of gluten, providing rigidity and elasticity to the dough and hydrating the starch granules. This causes a breakup of the smaller molecules which then serve as nutrients for the yeast.
Bread is the basis of the Mediterranean diet and is made from three simple ingredients; flour, yeast and water. Flour: good bread must be made from wheat flour, as wheat is the only cereal that has proteins (gluten) which can make a structure elastic enough to form a spongy consistency. The elasticity of the dough depends on the relationship between the glutenin and gliadin content. The large glutenin proteins are responsible for bread’s smooth, compact texture and gliadin, a thousand times smaller, confers elasticity to the dough.
In cooking, part of the water evaporates and the rest mixes evenly in the dough, creating starch gel inside the bread and coagulating the proteins in gluten, which then become the crust.
Yeasts: yeasts are responsible for the fermentation and rising of bread during baking, in addition to providing aroma and taste. Yeasts feed on maltose and other monosaccharides from the starch in wheat flour. During fermentation, yeast transforms sugars into carbon dioxide, ethyl alcohol, aldehydes, ketones and other taste-giving, aromatic alcohols. The carbon dioxide formed causes dough to rise during baking as it expands within the gluten.

Table 1 shows the main types of flour used in breadmaking according to its function.

Types of Andalusian white bread
Sensory attributes of white bread
In Andalusia, as in the rest of the country, there are basically two types of white bread: ‘candeal‘or ‘bregado’ bread, with a more solid, white crumb and a smooth, fine texture, and ‘flama’ or ‘barra’ (baguette-type) bread, which has a soft, spongy crumb.
Bread contains many aromas, flavours and textures that give it great sensorial wealth. These sensory properties, specific to each type of bread, depend mainly on the type of flour used, the breadmaking process and the baking.
•
•

Fermentation of dough is the natural way to give bread taste. In fact, fermentation is the ‘factory of taste’. This is carried out by the action of yeasts that convert the sugars in the dough into carbon dioxide, ethyl alcohol and other fermentation products that provide flavour and aroma to bread. Breads made with sourdough have greater aromatic wealth than breads made with industrial yeasts. Today, bakers use the latter in large-scale breadmaking.
Candeal or bregado bread, is made in Castile and Andalusia in the traditional way. This type of bread is called ‘white bread’ for its crumb, ‘candeal’ for the type of flour and ‘bregado’ for the refining process of the dough through cylinders. It is made with strong wheat flour and receives low hydration (around 40-45%). This means careful manual work which makes them more expensive than industrially-made breads and so endangers their survival. Fortunately, the revival in popularity of traditional quality products has helped this bread recover and it is now a representative of quality traditional breads. However, it is not usually made with candeal flour, as the cultivation of this variety has practically disappeared.
If fermentation is the factory of flavour, baking is the factory of colour and aroma, giving bread its golden colour and the typical aroma of freshly-baked bread. The browning of the crust and the development of aromas in the bread are due to chemical reactions at temperatures above 200 °C between the sugars and amino acids, known as the Maillard reaction. The main products formed in the Maillard reaction are furfural and their derivatives, which also make up part of the aroma of coffee, maltol, and the fruity, aromatic component, diacetyl – linked also to the aroma of butter and acetaldehyde which also have fruity notes.
Telera bread from Córdoba belongs to the candeal or bregado type of bread and is made in the traditional way in this city. It is characterized by a whitish crust, a white, compact crumb and a fine delicate sponginess. It is shaped like a bullfighter’s hat.
During bread tasting, the eyes take in the type of bread, colour and tone of the crust, colour and brightness of the crumb and the shape of the cavities. Through the sense of smell we perceive aromas of flour, yeast, spices, cereals or toast. Finally, in the mouth we appreciate both the basic sweet, salty or acid flavours, and its spongy, elastic, crispy and moist textures (Table 2).
Flama or barra, (baguette-type bread) is the most popular today. These breads are called ‘pan de flama’ because of their soft crumb. The dough is made with medium-strength wheat flour and receives average hydration (60-70%). It can be made mechanically which is convenient and profitable for the baker.
In Andalusia, as in the rest of the country, there are basically two types of white bread: ‘candeal‘ or ‘bregado’ bread, with a more solid, white crumb and a smooth, fine texture, and ‘flama’ or ‘barra’ (baguette-type) bread, which has a soft, spongy crumb.

BREAD
Sensory attributes of the Córdoba Telera bread Breads from different bakeries of Córdoba were subject to a sensorial analysis by the UCO analytical panel (GrupoSens AGR020) according to the procedure in the sensory profile (ISO 13299:2003). 24 sensory descriptors were used: 5 of appearance (colour intensity of the crust, colour intensity, tone, elasticity and sponginess of the crumb); 10 descriptors for the aroma/flavour (overall intensity; toasted; floury; cereal; salty; milky; malt; hay; earthy and rancid); 4 descriptors for the basic tastes (sweet, sour, salty, and bitter) and 5 for the texture (firm, crisp, elastic, spongy and moist). The results of sensory analysis show that there are large differences between breads for all the sensory attributes. A few showed a colour intensity of a dark crust while others were whitish; some had an elastic, spongy crumb structure while others were stickier; the olfactory notes of the crusts ranged from toasted while others had more floury, yeasty notes: on the mouth, most crumbs were mainly insipid with a sticky texture. This is because the sensory properties of the bread depend on the type of flour used, the breadmaking process and the baking method used ■

Salt can be extracted from both the sea and from land.
alt is a life giver, seasoning, flavour enhancer and conserving agent. The history of salt is closely linked to human survival. It is a mineral - sodium chloride, Cl Na - and is not only a conserving agent, but essential to ensure proper bodily functions. Together with water it may be one of the few essential elements besides, of course, food. It is indispensable for human diets, since without salt we become dehydrated and lose the essential fluid that keeps us alive. But salt in excess is dangerous. It needs to be combined with potassium to balance the fluids in the body - hence its importance in rural area, since food of plant origin contains a large amount of potassium which needs balancing with salt.
Warm seas, because of quicker evaporation have a higher concentration of salt than in cold seas. Continental Europe has numerous salt mines, such as those found in the Camargue, Guérande (France), the Austrian Alps, the Carpathians, Sicily (Trapani), and many other important sites. Because of the presence of this mineral, many prehistoric settlements grew up around it, like the salt mines of Hallstatt1 in Austria where there was a thriving culture in the Bronze Age. In Andalusia and on the east coast of Spain, there are large areas of salt flats along the coast and inland, together with many brackish streams and wells which have been in use for thousands of years.
Salt has been a symbol of wealth throughout our history and was used as a purifier in purification rituals, as a food conserver and as a means of avoiding dehydration and the loss of vital forces. Salt water is the symbol of entry to the Catholic Church for those who aspire to join, and is essential, therefore, in baptisms. Salt was also used in the same symbolic way by the Romans who sprinkled it on newborn babies. In pagan times, sacrificial victims were also sprinkled with salt, while a handful of it was thrown on fires to destroy evil spirits; even today, it is used in exorcisms. Years ago, Mediterranean hosts offered bread and salt, symbols of hospitality that none refused, and today, accidentally spilling salt is said to be unlucky.
The Romans attributed many properties to salt, especially sea salt, which they considered a gift from the gods of the ocean. Strabo2 mentions Turdetani salt extracted from mines and brackish rivers - vital for the fish salting industry which was so important in Andalusia at those times. A ‘salary’ was the ration of salt given per day to a legionary soldier, and was an exact amount. The salary could also be received in coins, although the origin of the word refers to an amount of salt.
Salt has been with us since the Neolithic Period, when man discovered its properties and how useful it was to conserve and season food. Thus, it is deep-rooted in religions and customs, essential for the symbiology necessary for health and serves as a food enhancer, Moreover, the Egyptians used salt not only for seasoning, but, when mixed with natron, as an essential element in the mummification process.

But after Sirius has been with his blazing fires, when the grass turns pale, when the land is parched, the water is cut off by barriers (cataractae). The sea stops flowing and the still waters solidify on the heated land under the persistent influence of the crust. During the Roman period, there was a flourishing trade in salt and the salt mining industry was well-developed. Salt was essential to preserve food, make salted pork, hams and other cold preserved meats, and was used regularly in cooking. It was placed on dining tables to allow people to season their food as they liked. It was also mixed with herbs and spices for flavouring - the sauce known as muria in Latin, or halmyris in Greek, was made by blending salt, thyme, cumin and vinegar (oxalme). Other sauces that contained large amounts of salt and a basic part of the diet were garum and liquamen. They were also used as seasonings, and the

lowest amount and Jaén the highest. The survival of salt mines until today can be explained, at least in part, by geographical isolation, which created a demand for local salt to give to livestock or to conserve the meat after a pig slaughter, or for the brine to dress olives. Some of these salt mines were extremely lucrative, giving rise to important salt mining complexes such as the Duernas salt mines in Córdoba - of great archaeological, architectonic and ethnologic interest. They cover 11.5 hectares and were the biggest in the province. Duernas has been mentioned in written sources since the 13th century, shortly after the Christian conquest. In 1491, it went to the House of Aguilar and then passed into the hands of the Dukes of Medinaceli. In the 18th century the dukes built the large complex, today almost in ruins, and depicted in L. Feduchi’s book Itinarios de Arquitectura Popular Española.

The Romans’ salt intake was high, apparently excessive, although there are no studies of ancient diseases which conclude that what today seems obvious, judging by the way that in rich countries we try to control consumption for health reasons. "Tejas Colorás", Baena. Therapeutic powers Dioscorides, author of the De Materia Medica pharmacopeia in continual use until the Renaissance, highlighted the major medicinal virtues of salt - although its properties had been discovered many thousands of years earlier. For Pliny, Andalusian salt was superior (N. H. XXXI, 80), and useful against inflammation and eye infections (N. H. XXXI, 86). According to Columella of Cádiz, salt was good for scars, lameness, scabies and mumps, (Columella’s De Re Rusticar VI, 12.1 - 13.1 - 32 - 33, VII, 10.3), as well as an excellent remedy for haemorrhoids and assumed to a purify because of the burning sensation felt when applied to wounds, taken as proof of its power to act on live bodies (Verse 64, 1105). Adding different ingredients to salt made it effective against bites and stings from scorpions, centipedes, wasps and even crocodile bites. Surprisingly, salt mixed with raisins or cow fat cured boils and, what is even more surprising, orchitis. Alone or mixed, salt blended with oil was a remedy for fatigue. Finally, the Bible mentions the custom of rubbing new born babies with salt (Ez. 16.4), and associates it with the notion of purity.
Since the foods we eat naturally contain certain quantities of salt, it begs the question why we add more salt in cooking or on dishes and whether we do it more out of habit than a physiological necessity. This question was solved at the end of the 19th century, when it was shown that salt was not necessary if the diet was meat-based, but if the diet was vegetablebased or a mix of meat and vegetables, then it was. Ancient indigenous hunter-gatherers already knew this, and with diets made up mostly of meat, milk and cheese, they had no need for salt. However, farming communities who began to settle in the land, ate mainly fruit and vegetables, and had to add much-needed salt to their food as a vital necessity and which, in itself, justified bygone struggles. Without salt we would not have been able to evolve toward a sedentary life and acquire culture, and as Pliny the Elder, referring to salt’s preserving properties, said, ‘Even the gods knew that civilisation was not possible without salt’. Horacio considered salt a food in itself and the Romans often ate it alone with bread, although as a delicacy, they sometimes
In veterinary medicine, Andalusian salt was highly regarded, and in the 1st century AD both Pliny (N H XXX, 100) and Columella (De Re Rusticar VI, 17, 39) wrote that it was used for eye diseases in horses and cattle, as well as in shearing and tanning (Columella’s De Re Rusticar VII, 4-8). In the 5th century AD, veterinary treatises such as the Corpus Hippiatricorum graecorum or Digesta artis mulomedicinae by Flavio Vegetio Renato, contain remedies created by Greek vets made with Andalusian salt. Regarding its industrial use, Andalusian salt was said to have the properties necessary to obtain the colour purple, so favoured by Roman patricians (Pliny, N. H. IX, 1).
put olive oil on the bread. The Romans’ salt intake was high, apparently excessive, although there are no studies of ancient diseases which conclude that what today seems obvious, judging by the way that rich countries try to control consumption for health reasons. According to the methodical Cato (De Agricultura, 58, 14) the annual ration of salt for a slave was a measure called a modio (8.75 l.), and more than double the sodium chloride a normal organism needed according to dieticians and bromotologists, although, perhaps considering how poor a slaves diet probably was, the salt may have been beneficial.

SALT
As a result of the reaction of the unstable metal, sodium and the poisonous gas, chlorine, we get salt - something we have needed for millennia to survive. Salt is essential for growth, reproduction and correct motor functions because sodium acts in the transmission of nerve impulses. It also aids the absorption of nutrients such as glucose - and maintaining adequate levels of these nutrients is vital for good health.
Conserving properties Since ancient times, salt has been used to preserve foods of mainly animal origin, although vegetables were also salted to prevent them from rotting. Besides conserving foods, salt also helped during the ripening or curing processes. Once cured, food could be stored in times of plenty and used when scarce. Perishable foods could be transported to inland places - foods like fish, which Christianity had made popular as the traditional food for Lent. In fact, fish was part of people’s staple diet for 150 days of the year. The curing of fish or meat was a method passed on by Phoenicians and Greeks to the Romans, who began to use this method for keeping oil, olives and cheeses, and who even added it to wine to make it more palatable. This tradition continued during the Muslim domination of Andalusia, where the famous Malaga anchova was produced and widely consumed in the
Western Mediterranean. This was an industry which, like tanning, needed large amounts of salt from the salt mines of the inland Nazari Kingdom, spread throughout the valleys in the Baetic system in Andalusia. Indeed, there is a wealth of data on salt consumption and its use in the al-Andalus region found in both agronomic and culinary treatises, like the hisbah which lays out the control of the markets at that time. In the Middle Ages, salted fish became an important source of protein for inland populations. The same process was applied to the meat either from domestic stock or from hunting, and which was first salted then cured for later consumption.
In the Modern and Contemporary Period, meat curing first took place in the US in New England, where not only beef and pork was salted, but also deer and even bear. The origin of Uncle Sam comes from the fact that during the 1812 war, barrels of cured meat sold by Sam Pynchon to the army had US stamped on the side. Eventually, US began to stand for ‘Uncle Sam’s meat’. The letters ‘US’ were stamped on all army supplies, and finally Uncle Sam became a synonym for the government of the United States itself.

Himalayan salt “Oil, wine and salt: royal commodities”: the state monopoly Because salt was so essential, the state sought control of its production and distribution - above all because salt flats were relatively scarce and salt consumption was universal. There is no evidence that monopolies were set up in the pre-Roman era, but Latin sources indicate that from 204 BC the Romans, like the Egyptians who used salt in the mummification process, imposed a vectigal; a tax on salt which regulated its maximum sale price, in other words, a state monopoly on the salt mine. Distribution was controlled by treasury salt operators, the salinatores aerarii.
The
government controlled prices and distribution by keeping all the salt in its warehouses or horrea, thus creating a state monopoly of salt which lasted until long after the death of Constantine in AD 337. Later, salt taxes, or gabelles, levied by medieval European states on salt, helped to greatly swell government coffers. Regulations to control profits from the salt tax levied by King Alfonso X and his great-grandson Alfonso XI, were extended in 1484 by the Catholic Kings, who decreed death by bow and arrow to all salt fraudsters. In fact, this measure was never imposed, and was replaced by penalties which ranged

However, further research needs to be done to learn more about the relationship between livestock and salt, as well as other aspects of the archaeology of salt, despite some progress with regard to prehistoric times and, to a lesser extent, to the medieval period.

The result is hypertrophy or hyperplasia of the thyroid tissues (goitre or hypothyroidism). This is usually remedied in less serious cases by including more iodine in the diet, although in persistent cases may require an intake of thyroxine. The lack of iodine in mothers can lead to cretinism (mental retardation) in neonates. The UN considers this element essential for intellectual development.

Sodium in the diet Common salt or table salt is composed of chlorine (Cl) and sodium (Na), which together form sodium chloride (NaCl). Foods and drinks that contain sodium chloride (39% of sodium in weight) are the primary source of sodium. Other salts, like sodium bicarbonate or monosodium glutamate, contribute less than a 10% of the total intake of sodium in our country, and may be higher in other countries where glutamate is used as a condiment. Water has a sodium content of less than 20 mg/L, contributing less than a 10% of total sodium intake. The sodium we consume comes from three sources: •
Natural sodium from foods (8% of the total consumption of sodium)
•
Added sodium: salt added during cooking and seasoning (20% of total salt consumption)
•
Added sodium in food processing: (72% of the total intake)
In view of this, diets high in sodium tend to be comprised of manufactured products, while low-sodium diets are based mainly on fresh fruits, vegetables and legumes. According to the ENIDE AECOSAN (2011) study, the main contributors of sodium in the diet are those reflected in Table 1:

An increase in arterial blood pressure causes 5% of the total deaths from cardiovascular disease. If the problem is chronic, it can mean a loss of elasticity in the arteries leading to heart failure and kidney disease, which in turn can lead to strokes3 and heart attacks4 - the two most common causes of death and disability in developed societies.

Moreover, a high percentage of people who survive a stroke suffer serious physical and neurological sequelae for the rest of their lives. 4 Heart failure and strokes: salt also has direct adverse effects on the heart muscle and if the heart is unable to pump blood to the body, heart attacks or heart failure may occur.

gustatory nerves to taste centres in the brain. There are four basic traditional tastes: salty, sour, sweet and sour, while a fifth basic taste, umami, has been identified - and even a sixth ‘metallic’. The basic sweet taste is perceived mainly at the tip of the tongue; salty on the side of the tip of the tongue; sour is detected on the sides, and bitter at the back. The papillae that perceive the bitter taste is found further back on the tongue, so this taste takes a long time to appear, but once it develops it lasts longer (Jellinek, 1985). According to ISO 5492:2010, saltiness is the main taste produced by aqueous solutions made up of various substances such as sodium chloride. Perception is related to the presence of salts in food and its intensity depends on the type of salt and its concentration. It is now accepted that ion Na+ is mainly responsible for the salty taste, although ion Clplays an important role because of its high electronegativity (Bartoshuk, 1980).
The sense of taste is part of our chemical and

3.6 mg of sodium/day (9 g of salt/day). Consequently, the agri-food industry is reducing the amount of sodium in their products. However, given the significant effect that has salt in the sensory characteristics of food, this is not an easy task. The question is how to reduce the amount of salt in food to suit the demands of consumers. One way could be to replace table salt (with high sodium content) with other lowsodium salts.

The results of the direct sensory analysis of the samples indicate that all the salts are odourless. Fleur de sel is characterized by being white, shiny and the least salty of all, maintaining the intensity of its saltiness during tasting. The salt in grain form is white, shiny, and has a medium intensity saltiness that dissolves slowly in the mouth. Salts flakes are saltiest, white, less shiny than the others and dissolve quickly in the mouth, gradually growing in intensity. Of the two types of salt flakes, the slightly saltier sample is also bitter and spicy. From the sensory analysis of aqueous solutions of salts, it was seen that all the samples have an average intensity of saltiness, with little differences among them, except in one of the flake salt samples which had a slightly inferior taste ■

THE SALT OF LIFE AND THE LIFE OF SALT EMILIANO MELLADO ÁLVAREZ GABELA DE SAL. TRADITIONAL SALTWORK Salt is the sublime essence of ancient seas covering the calm Cordoban lands. Hidden white gold, born in the salt flats at the hand of the salt miner - countryman and salt artisan.
U
For more than five thousand years, salt has added to flavour to food, provided man with essential minerals, been used in fish, vegetable and meat conserves and is included in feed for livestock. It also provides the raw material for the tanning of skins, magical cures and ancestral rituals of worship.
ntil very recently, a salt miners’ life started in the rustic abodes found in the salt flats of the area. As children, these inland salt miners played among mud, stones and mounds of salt. Salt miners were in fact more like farmers than miners and each salt harvest brought new knowledge, which was then passed down from father to son and from salt mine to salt mine.
Indispensable and nourishing, salt was a high-value commodity on which strict controls were imposed and monopolies set up by the crown or the state, and which lasted for hundreds of years until the mid-19th century. These were times of monopolies, but they were also times of salt smuggling and theft from royal salt mines and hidden crystallisation ponds, tax controls and decrees on salt production and sale, salt taxes, administration and administrators, shelters and shelter builders.
Gabela de Sal is a business initiative that aims to recapture the traditional taste of Córdoban salt, awaken the historical memory of the old salt miners of the countryside, restore and enhance the value of the salt mining heritage, incorporate both tradition and innovation into the salt mining industry and encourage salt production and consumption of Córdoban salt. The origin of salt
After the freeing up of salt production many more salt mines emerged, some as a result of smuggling control, others as new businesses run by the rural bourgeoisie. A market was established in which the large state-owned salt mines kept their privileged position, since their size allowed them to supply large sections of the population, while other smaller salt mines supplied a local market - which cut transport costs and gave them a competitive edge.
We associate salt with the sea, coastal salt flats and the piles of salt seen from the road in the Bay of Cádiz, Huelva and Cabo de Gata in Almería. We forget that, until the middle of last century, the hundreds of salt mines in the Andalusian countryside were the fundamental, and only, source of salt for cities and provinces like Córdoba and Jaén, as well as for villages found far from the coast in Seville, Cádiz, Granada, Málaga and Almería. Salt from inland salt flats and the coast have a common marine origin. However, inland seas are not the current source of brine for salt extraction. From the evaporation of ancient seas that covered a large part of the Iberian Peninsula, halite emerged, a rock salt that appears as a mineral layer under the ground and which, in contact with the underground water, generates saline aquifers that reach the surface in the form of ponds, wells and salt springs with concentrations that vary between 150 and 250 g/L, compared to 35 g/L of salt from seawater.

SALT
Córdoba was and is a land of salt, of production in low-lying areas in the south of the province and consumption in the highlands of pasturelands and cheese. Coinciding with the salty nature of the terrain, in the province there were two large salt-production regions connected to the large rivers of the Córdoban countryside, the Genil and Guadajoz. In both cases, salt is present in the form of a crust, foam or natural deposit in abundant lagoons, springs and streams.
when production in the royal salt mines was low. Today these original salt mines still exist, albeit in differing states of conservation and exploitation.
Improvements and lower production and distribution costs, allowed coastal salt mines to supply traditional inland markets and meet growing industrial demand with greater guarantees. The industrialisation of salt supply and demand breaks with traditional inland salt mining. From the mid-20th century, they were also subject to new mining regulations and food controls which meant a significant increase in production costs, new taxes and quality controls that were difficult for traditional salt miners to accept or even understand. Gradually, dozens of inland salt mines were suspended or deregistered for non-payment. Nowadays, inland salt production takes place in a small number of salt mines.
In the south, Aguilar de la Frontera is one of the most important salt mining areas where three salt mines are found: Nuestra Señora de los Remedios, Puentes de Montilla and La Encarnación, which cover more than five hectares. Also incorporated into this complex of mines after 1956, was the half-hectare Salina de Nuestra Señora de la Antigua salt mine - now abandoned. In Montilla and Lucena, the San Francisco, La Encarnación and the Mercader salt mines appeared. And in the Subbetic countryside, with the highlands painted white with snow in winter and lowlying areas painted white with salt in summer, we find the salt mines of San Juan de Dios (Rute), El Salado and Los Montoros in Priego de Córdoba and Nuestra Señora de La Esperanza in Cabra.
Córdoban salt mines Córdoba was and is a land of salt, of production in lowlying areas in the south of the province and consumption in the highlands of mast and pasture feeding systems and cheese. Coinciding with the salty nature of the terrain, in the province there were two large salt-production regions connected to the large rivers of the Córdoban countryside, the Genil and Guadajoz. In both cases, salt is present in the form of a crust, foam or natural deposit in abundant lagoons, springs and streams. These natural crystallisation ponds would be the first salt harvesting places and would give rise to a network of production centres that spread throughout the south.
The Guadajoz basin, Flumen Salsum to the Romans, or Guadaxox to the Moors and Christians, is the salt flat region par excellence in the province of Córdoba. This is where the Duernas and Cuesta Paloma saltworks were the main inland mines - both of the province and in the whole of Andalusia - producing about 10,000 to 20,000 bushels of salt a year during the monopoly period. From the Guadajoz salt mining era, only the Duernas salt works remains. Now renovated, the mine produces around one million kilos of salt annually. Important mines, such as the Cuesta Paloma in Baena and Santa Lucia in Valenzuela, remained active until the late 20th and early 21st century, although most have been buried under the sediment of the streams and the new olive grove. Nevertheless, some mines do continue to function, more out of nostalgia for the old saltworks than for their profitability.
Of these salt mines, those in Duernas, Córdoba, Cuesta Paloma, Baena and Los Jarales in Lucena played a significant role during the time of state monopolies. These salt mines supplied salt to storehouses in the mountainous regions, the surrounding rural areas and the Subbetic region. There were also smaller mines and natural crystallisation ponds where, subject to local control, salt could sometimes be extracted

In the Laguna de la Quinta Nature Reserve near the Vaquillero
The salt lands form an extraordinary landscape and are found in wetlands of high cultural value. Against a dry landscape, there are hundreds of different shades of white produced by salt, together with the rich green of Salicornia, pink of brine shrimp and orange of flamingo, red and ochre of storage buildings and basins, low, rolling hills hugging salt streams and wastelands of stone and gypsum. This is the typical landscape of salt flats and also of the Baena salt mines, unchanged since salt-mining families lived here years ago. However, today there is only silence, and no sign of the mallets, baskets, shovels and rakes which once made up the salt miners’ tools.
River, the most important salt mine was the Rincón del Muerto, followed by the San José de Covatillas salt mine found further upstream. Downstream, El Conejo salt mine produced salt until the 1980s and was closely linked to the Salina de Santa Lucía salt mine in Valenzuela. There were also other smaller mines attached to country estates, such as Fuentidueña, Gangas, Gastaceite, Covatillas and las Alberquillas, and natural crystallisation ponds like El Saladillo and Pedro Ortiz. Because of its large number of salt mines, Baena was one of the most important salt producing areas in Spain, with
Although there are very few more modern salt mines left, there are still documents about salt mining in the 13th, 17th, 18th and 19th centuries. These documents include the Ordinances of the Baena Salt Mines (1526), the results of the Catastro de Ensenada census (1752), documents concerning the building of a new floor in Albendín church (1788-1790), and statistical data relating to Baena Miñano (1827) and Madoz (1848), the most comprehensive report made by the administrator of the royal salt mines in Córdoba (1853).
a total of 20 mines in full production until late last century. Some date back to the Reconquest and were under the control of the Calatrava Order and the ancient Albendín and Baena seigniories. Of even earlier origin might be, among others, the salt mines of Cuesta Paloma, Rincón del Muerto, Tejas Colorás, Las Roblizas and Vadofresno. Baena’s richness in salt is due mainly to hydrogeological factors, i.e. the presence of salt and water underground.
But salt is also present in folklore, superstitions, rituals and shared customs, found in the kitchens of both lords and peasants where it is put in basic gazpachos made from bread, olive oil and salt (also known as ‘mazamorra’ or ‘pava’). Salt is present too in pig slaughters and the salting factories of the governing classes and makes up the white carpet laid down for the Corpus procession - besides being put in bags for house warming ceremonies.
This is followed by the spatial and temporal organisation of the land, as a geographical area inhabited over time which explains the patterns of salt mine distribution. A salty substrate, a source of water, a cattle track or traditional livestock path, settlements and old towns are key aspects to understanding the richness and diversity of the Baena salt mining heritage.

he supposedly very beautiful and equally arrogant Cleopatra VII, last queen of Egypt, was the protagonist of the most expensive meal in history.
During her love affair with Mark Anthony, she wagered she could spend a million sestertii1 on a dinner. Mark Anthony, dumbfounded, accepted the wager and while eating the most exquisite dishes he mentally calculated how much the meal could have cost – and it did not seem excessive. During the desert course, Pliny the Elder2 recounts how Cleopatra asked the judge to put a price on the two pearl earrings she was wearing. He valued them at about five million sestertii each. To everyone’s amazement, Cleopatra dropped one of the pearls into a glass of wine vinegar and once the pearl had dissolved, drank it. The acidic nature of the vinegar had dissolved the calcium carbonate of the pearl and Cleopatra won the wager, having drunk more than € 7,000,000 in today’s money. Moreover, Egyptian vinegar had always had

The history of vinegar is inseparably linked to that of wine production, so much so that when the fermentation process was unsuccessful, some wine growers would say, “God is trying to make vinegar - and it is our duty to help him.” Although in Mediterranean cultures the true protagonist is wine vinegar, any liquid is considered vinegar if it is apt for human consumption, produced by double fermentation - alcoholic and acetic – and is made from agricultural products containing sugar. There are some vinegars that have been made since ancient times, like those from pears, apples or figs as Columella3 writes, and even from chard, palms4 or sea onions5.

Although the creation of vinegar was accidental and all its ‘mysteries’ were not revealed until the 19th century, we have now reached a stage in which we use technologies such as bioreactors in its production. Vinegar production as an industry in its own right started in the Middle Ages, when the craft was developed and firmly established in European cities – so much so that in 1394 the Corporation of Vinegar Manufacturers was officially recognised. Numerous recipes have been conserved from classical times and Casiano Baso6 in the 7th century tells us, based on another compiler of agricultural knowledge from the 4th century, how to make both sweet and strong vinegar, how to preserve it and how to avoid being cheated with watered down vinegar, a common practice in those days: “Add potassium nitrate7 to the vinegar, and if it rises as though it were boiling then it contains water.”

According to Livy9, the Carthaginians heated them10, so clearing the way. Written references to vinegar become far more prolific from the Roman era onwards. It was lauded as a vital condiment, an essential conserving agent and with highly effective medicinal and cosmetic properties, always bearing in mind though that the quality of the vinegar will always depend on the quality of the wine used in its preparation. From Roman times to the present day the process for obtaining vinegar has been in a continual state of refinement.

precious liquid transform dishes into a veritable feast for the senses and, besides featuring in many recipes, vinegar is also used in natural remedies to prevent and cure a multitude of illnesses. These remedies sprang from popular wisdom, which knew how to make best use of its beneficial properties, such as its Vitamin A content. This may also have been the origin of many of the pickles that we consume today, such as pickled capers, a very common remedy used frequently and effectively since ancient times to cure scurvy and other vitamin deficiencies. Both Hippocrates in the 5th century BC and the Bible attribute medicinal properties to vinegar and mention it as a healing remedy. Thus, we find it as a component of aids for digestion, such as vinegar and thyme or pennyroyal brine. According to Pliny17 it was excellent in poultices for the eyes and cured leprosy sores, all kinds of rashes, ulcers and even healed wounds from dog, scorpion and vermin bites. As many as three hundred therapeutic uses can be attributed to its main characteristic, its acidity. It continued to be used medicinally throughout

INTRODUCTION Besides its nutritional content and its health-giving properties discussed later in this chapter, vinegar has been without doubt a nutritional supplement of the highest order. In addition to the unmistakable flavours and aromas it gives any dish, it has been used for centuries as a food preservative in pickles and marinades.

Other components of significant nutritional interest are the phenol composites, which evolve over time in vinegars matured in barrels, and which vary in their content according to the differences in the wines from which they are produced. Gallic acid predominates (3-50 mg/L), then tartaric acid (3-66 mg/L) followed by hydroxymethylfurfural (1-16 mg/L). Whereas tartaric acid and hydroxymethylfurfural diminish in storage (depending on the type of ageing), tartaric acid increases (García Parilla 1999). Other compounds that can be detected in vinegar in very small quantities are tyrosols, flavonols, stilbenes, ellagic acid and even anthocyanins (in vinegars from red wines. Cerezo et al. 2010). These acids are of special interest because of their antioxidant effect, which helps to prevent illnesses like cardiovascular diseases, cancer and senile dementia. Lastly, other compounds recently identified (Verzelloni 2010) and seen to have antioxidant effects, are melanoidin molecules formed due to the Maillard reaction of sugars on amino acids. This occurs in the final stages of production (ageing) of traditional Modena balsamic vinegar (not reported to date in other types of vinegar)

THE EFFECTS OF VINEGAR ON HEALTH
T
The external uses of vinegar One of the best-known factors contributing to heart disease is high blood pressure that affects more than 65% of Spanish people aged over 60. Different studies have been carried out on this risk factor which have shown the beneficial effects that vinegar, or to be more exact, acetic acid, have. Studies carried out mainly on rats (Kondo et al 2001; Honsho et al 2007) have shown reductions of up to 20 mmHg in the systolic reading of spontaneously hypertensive rats. The active mechanism seems to be related to a slight inhibition of the angiotensin enzyme activation. Inhibitors of this enzyme are commonly used to treat high blood pressure in humans, and it appears to have the same effect in rats.
he first references to the health benefits of vinegar describe its external use, applied on the skin to wounds or burns to prevent possible infections (Hippocrates 460-377 BC).
Since ancient times its ability to repel certain insects like lice has been known, making this a widely-used remedy long before modern insecticides were invented. Vinegar was also used in cough medicines, while oxymel (four parts honey to one part vinegar) has been used in traditional medicine and is still used today - it was even included in British and German pharmacopoeias at the end of the 19th century. Vinegar solutions (2% acetic acid) can be effective in treating outer and middle ear infections, but must be used with caution since the acid pH (around 2) can irritate inflamed skin and may damage the outer hair cells of the cochlear. The effectiveness of
other components can also have this effect. For instance, the use of
Another factor contributing to heart disease is a high concentration of serum cholesterol and triglycerides. In this sense, the acetic acid in food, and which is present in the body as acetate, has been shown to reduce both serum cholesterol and triglycerides. (Fushimi et al. 2006; Yamashita et al. 2007). The effect may be related to a reduction in a series of enzymes implicated in the regulation of the production of lipoprotein transporters of cholesterol and a reduction in the synthesis of fatty acids. An increase in elimination of bile acids through faeces has also been observed, which then forces a new synthesis of these components from the cholesterol molecules. This triple effect observed in rats is how acetic acid acts on hypercholesterolemia and hyperlipidaemia.

Vinegar and Cancer
vinegar as a remedy for treating fungal nail infections or warts has yet to be scientifically proven. Using vinegar as a disinfectant (on worktops, bowls etc.) should be avoided because even though it is a disinfectant it is not as effective as other commercial disinfectants and can give us a false sense of security. The antimicrobial effect of vinegar in food Vinegar can be seen to have the same effect on wounds as on food, where it exerts an antimicrobial effect due to its acid pH, although

The link between cancer and diet is well-known, and several international organisations recommend healthier lifestyles to prevent cancer. The WHO (2015) sets out the factors linked directly and indirectly to diet as key elements in the prevention or treatment of cancer. Obviously, smoking is in first place, but 2nd, 3rd and 5th respectively are obesity, an unhealthy diet with insufficient intake of fruit and vegetables and alcohol consumption. In 4th place is physical inactivity, which although it is non-dietary should be adapted to an individualâ&#x20AC;&#x2122;s food habits in order to avoid obesity, another trigger for cancer.
and is just as effective on lettuce (Vjayakumar and Wolf, 2002). Vinegar and heart disease Risk of suffering heart disease is the result of various concurrent factors and because of its long-term action triggers a pathological process. Most of these factors are silent and may go unnoticed by a future patient, although others can be detected early. Among these factors there are some that can be modified by following certain diets. In this sense, the benefits of extra virgin olive oil, fruit, vegetables, whole grains, nuts and even wine are well known. A
In fact, there are several reasons why it is difficult to prove a link between certain foods and cancer; firstly, the causes and evolution of different types of cancer are not necessarily the same, so what may be beneficial in one type of cancer is not necessarily beneficial for another. For example, wine consumption in moderation is often said to be beneficial against cancer, while excessive consumption can be linked to cancer in parts of the digestive system, including the liver.

A case of hypopotassaemia was reported after a six-year, 250 ml daily dose of apple vinegar was consumed. These are extreme cases, but should be considered in order to avoid excessive intake.
Studies on these satiating effects are normally based on the contribution of different foods with similar calorific content and the subjective evaluation of hunger/ satiety over a relatively long period after consumption (Reina et al., 2015). A study was carried out which measured satiety in persons that had eaten 50 grams of white bread and given varying quantities of acetic acid, from 0 (control) up to 1.7 g. It was found that the food providing the least satiating effect was bread on its own, and that higher quantities of acetic acid produced a greater satiating effect (Ostman et al., 2005). This effect seems to be related to another effect mentioned above, namely maintaining glycaemic levels, a factor involved in the hypothalamic centres controlling hunger and satiety.
Another point to consider about the effects of large quantities of vinegar is the variable histamine and tyramine content. In a study carried out on 15 Spanish vinegars, (Vidal-Carrou et al., 1989), histamine levels oscillated from 0.2 to 17.3 mg/l, while tyramine levels were from 0.93 to 10.7 mg/l. The averages of both are much higher than in the wines, vermouth and cider analysed in the same Spanish study, which is why special care is needed in the appearance of histamine syndromes. Modern production techniques using wood chippings to accelerate vinegar production is of concern to consumers because of the possible presence and infiltration of polycyclic aromatic hydrocarbons, and especially cancer-provoking benzopyrenes. Regarding this, it was reassuring to see that in a study by Chinnici et al. (2007), the levels of these substances are very low, irrespective of the type and size of the woody chips, and were below the legal limit for food
Antioxidants in vinegar and health In the ‘Composition of Vinegar’ section, we saw how antioxidants levels differ and fluctuate according to the type of wine used in its production. However, antioxidants are not only found in wine vinegar, they also occur in vinegar made from other fruits, especially red fruits. The amounts of antioxidants found in these vinegars, vary depending on the origin of the fruit and the method of production. The content of some of these compounds, particularly phenols, has been mentioned above, although the antioxidant effect of vinegar is not always proportional to the content of these substances, as shown in a study by Alonso et al., 2004. It was found that the strongest antioxidants were cis-p-coumaric acid, vanilla and benzaldehyde, present in small quantities. Furthermore, a vinegar’s antioxidant capacity depends on if it has been aged in wood or not. If not, then gallic acid has the strongest antioxidant effect, besides being one of the most plentiful. However, if aged in wood, ferulic acid (that without the influence of wood has an irrelevant role) takes on special importance in the total correlation with the antioxidant. Nowadays, antioxidant compounds are the most studied substances in food compositions, thanks to their decisive role in lessening the incidence and severity of illnesses associated with heart disease, strokes, cancer, diabetes, senile dementia, etc.

Although the consumption of vinegar and pickled foods has been documented for over two thousand years without any known adverse effects, the ´medicinal´ use of vinegar can have harmful effects either because it is too highly-concentrated or drunk without food. In this regard, concentrations of acetic acid higher than 20% may be toxic and cause damage to the cardia or oesophagus. In fact, if vinegar even with a normal acetic acid content is drunk alone, it may have adverse effects on the oesophagus and cardia. Due to inhalation, a further effect may be laryngospasm or vasovagal syncope.

vinegar), and the production method used (acidification methods with surface culture or submerged culture). Wine vinegar is the result of the acetic fermentation of wine by the agency of acetic acid bacteria. In Mediterranean countries it is mainly produced in steel vats and with submerged culture, which is then aged (or not) in wood. These vinegars are becoming ever more popular amongst consumers, and vinegar producers are trying to create finer quality products. Among Andalusian vinegars with international recognition and designation of origin, some of the most outstanding are ‘Vinagre de Jerez’ ‘Vinagre del Condado de Huelva’ and ‘Vinagre de Montilla-Moriles’.

BACKGROUND
S
eventually became inexorably linked with the name of the people. In fact, it was this unique land that produces such high quality wines that gave the town its name.
ince time immemorial, wine has been identified and classified by the name of the region in which it is produced. The Egyptians, Greeks and Romans left behind much evidence of this; the wines from Cyprus, Falerno and the Bética were famous. In the Iliad and the Odyssey, Homer (9th century BC) writes about the wines of Lemnos, Samos, Petalas and Ithaca. As their prestige increased, so did the false imitations. In the 17th century, leather sacks of Lucena wine were sold which contained wines from regions further afield. Fraud was always punished, but it was not until the late 19th century that the first legislation was passed to regulate the use of geographical names, and, in 1883, the Paris Convention for the Protection of Industrial Property was signed.
The complete denomination as known today, was first applied in 1891 to celebrate the Madrid Agreement, later revised in Washington in 1911 and approved by The Hague in 1925. But it was the 1932 Vine and Wine Statute that gave legal protection to the names of these two towns so that they could be used exclusively by the growers and producers of the region. On 6th December 1932, a directive was published in the Madrid Gazette fixing a deadline of 15 days to establish the Regulatory Council of the Denomination of Montilla. On December 22nd, the Gazette also gave instructions for the establishment of a Regulatory Council for Moriles.
It wasn’t until 1947 that, due to the growing importance of protecting geographical quality, the International Office of Vine and Wine approved an initial definition: “a wine cannot be attributed designation of origin unless it has been consecrated by use and enjoys a demonstrable reputation”.
The Civil War and other bureaucratic problems delayed the founding of the Regulatory Council which did not take effect until December 1944, with its statutes finally approved in October 1945. The first President was Luis Merino del Castillo, then Chief Engineer at the Cordoba Agronomy Headquarters. Members included: Francisco de Alvear, Count of la Cortina; Félix Asensio Navarrete, Antonio Víbora Blancas, Rafael Cruz Conde, Julián Pérez-Barquero and Luis González Ruiz. Secretary: Francisco de Paula Salinas Casana. Finally, in December 2011 the Agriculture, Fisheries and Environment Council published the Directive of November 30th which approved the statutes regulating the Designation of Origin ‘Montilla-Moriles’ and ‘Vinagre de Montilla-Moriles’
The name ‘Montilla’ came in to general use around the mid19th century, drawing together and embodying a region that was already producing exquisite wines. Indeed, wines produced in other areas of the region, known today as ‘DO Montilla’, participated in international competitions under the generic name ‘Montilla’. That of ‘Moriles’ became renown in 1912, when the old name of the town, Zapateros, was changed to the current one. However, although the wine-growing areas here were already well-known and highly-esteemed, the wine

AN OVERVIEW OF VINEGAR
T
he word ‘vinegar’ comes from the Latin vinum acre from which the French vin aigre derives, meaning ‘sour wine’. Vinegar was discovered more than 10,000 years ago and our ancestors quickly recognised the remarkable versatility of vinegar for different uses (preservative, dressing, refreshment, medicine, solvent, cleaning product etc.).
Types of vinegar •
Wine vinegar: obtained exclusively from the acetic fermentation of wine
•
Fruit vinegars: obtained from fruits or berries
•
Cider vinegar: obtained from cider or diluted cider spirit
There are certain basic to be considered when talking about vinegar:
•
Alcohol vinegar: obtained from the acetic fermentation of distilled agricultural alcohol
•
Vinegar is a liquid fit for human consumption, produced by double fermentation, alcoholic and acetous, of agricultural products containing sugars or starches.
•
Grain vinegar: obtained from the double acetic and alcoholic fermentation of any cereal grain whose starch content has converted into sugars
•
The total acidity of vinegar should not be less than 50g/l, except in the case of wine vinegar which should be at least 60 g/l.
•
Malt vinegar: obtained from the double acetic and alcoholic fermentation of malted barley
•
Acetic content: this is the total acidity of vinegar expressed in grams of acetic acid per 100ml at 20º Celsius.
•
Other vinegars: obtained from other not previously mentioned agricultural products (honey, whey etc.) by double fermentation
The regulations governing vinegars on a national level, both ordinary vinegars and those from Designated Origin, are in the Royal Decree 661/2012.

This is a system of dynamic ageing consisting of the partial extraction, or ‘saca’, of wine from each of the casks, categorised on an ageing scale, and the ‘rocío’, or replacement of the wine extracted, with vinegar from a different scale or younger vintage. Non-vintage vinegar is used to replace the younger ones. This way, every vintage contains a proportion of all the vinegars of all successive vintages that have been used to replace the original. The last vintage at the end of the ageing process is the solera. From here the mature vinegar is extracted, and is the result of a homogenisation and prolonged ageing of vinegars from every vintage - from the first to the very last - when it was finally replenished, or ‘rociada’.
