Malt Vinegar: A Versatile Condiment with Culinary, Health, and Household Benefits

Malt vinegar is a traditional vinegar made from malted barley grains, undergoing a unique two-step fermentation process. The process begins with the germination of barley grains, which are then dried to produce malt. The malt is brewed into ale, and through fermentation, the alcohol in the ale is converted into acetic acid, creating malt vinegar. This method gives the vinegar its distinctive deep, rich, and slightly sweet flavor profile, which differentiates it from other vinegars like white or apple cider vinegar.

Known for its tart and tangy taste with subtle caramel notes, malt vinegar is a staple in British cuisine. It is most famously used as a condiment for fish and chips, where its acidity cuts through the greasiness of fried foods, providing a well-balanced contrast. Beyond fish and chips, malt vinegar is also used in pickling, marinades, salad dressings, and even as an ingredient in sauces and chutneys. Its robust flavor enhances meats, roasted vegetables, and even soups, making it a versatile kitchen staple.

Apart from its culinary applications, malt vinegar offers several health benefits. It contains acetic acid, which has been linked to improved digestion by stimulating digestive enzymes. Studies suggest that acetic acid can also help regulate blood sugar levels, making it beneficial for individuals managing diabetes. Additionally, malt vinegar exhibits antimicrobial properties, which aid in food preservation by inhibiting bacterial growth. Some research also indicates that vinegar consumption may support weight management by promoting a feeling of fullness, thereby reducing overall calorie intake.

Beyond health and culinary uses, malt vinegar has practical household applications. Due to its acidity, it serves as a natural cleaning agent, effective in removing stains, descaling kettles, and even acting as a deodorizer. Some gardeners use diluted malt vinegar as a weed killer, leveraging its natural acidity to inhibit plant growth.

Recent market trends indicate an increasing interest in natural and fermented foods, boosting the popularity of malt vinegar. With a growing emphasis on traditional ingredients and their health benefits, malt vinegar remains a relevant and widely appreciated condiment in modern kitchens. Whether used for enhancing flavors, improving health, or practical home applications, malt vinegar continues to be a valuable and versatile product.

Health Benefits of Beta-Glucans in Barley: Heart, Blood Sugar, and Immune Support

Beta-glucans are a type of soluble fiber predominantly found in barley, recognized for their numerous health benefits. These polysaccharides are embedded in the cell walls of barley grains and have a profound impact on cardiovascular health by lowering LDL cholesterol, commonly referred to as "bad" cholesterol. When consumed, beta-glucans form a gel-like substance in the digestive system. This gel traps cholesterol and slows its absorption, preventing it from entering the bloodstream. In turn, this action helps reduce overall cholesterol levels, particularly LDL cholesterol, which is a major risk factor for heart disease. This mechanism also benefits individuals with metabolic conditions, as it helps stabilize blood sugar levels by slowing the absorption of glucose. For people with type 2 diabetes or those at risk, consuming barley with beta-glucans can contribute to better glycemic control, minimizing dangerous blood sugar spikes after meals.

Furthermore, beta-glucans offer more than just heart health advantages. They have been found to enhance the immune system by activating key immune cells, such as macrophages and natural killer cells, which are essential for detecting and eliminating pathogens. These immune cells play a crucial role in protecting the body from infections, and their activation by beta-glucans boosts the body’s natural defense mechanisms. This immune-modulating effect can make individuals more resilient to illnesses, potentially reducing the frequency of common infections like colds or more serious conditions.

Incorporating barley into daily meals is an effective way to benefit from its beta-glucan content. Barley is a versatile grain that can be easily added to a variety of dishes, such as soups, stews, and salads. Both hulled and pearled barley varieties are rich in beta-glucans, though hulled barley is considered nutritionally superior since it retains more of the grain’s natural nutrients. For individuals looking for whole-food alternatives to manage cholesterol, regulate blood sugar, or support immune function, barley serves as a nutritious and accessible option.

In summary, the inclusion of beta-glucans from barley in the diet can provide substantial health benefits, particularly for heart health, blood sugar management, and immune system support. With its wide range of uses in cooking and its powerful effects on wellness, barley stands out as a beneficial food for promoting long-term health.

Unlocking the Health Benefits of Barley and Rye: The Case for Including Minor Cereals in Our Diets

Barley and rye are often categorized as 'minor cereals' because they are not as frequently consumed as 'major cereals' like wheat, corn, rice, and oats. However, nutrition experts emphasize that these 'minor' whole grains should be included more prominently in our diets due to their substantial health benefits.

In recent years, the popularity of cereals has surged, contributing positively to public health. Yet, many people remain unaware of the nutritional advantages offered by lesser-known whole grains such as rye and barley. Increasing awareness and consumption of these grains could significantly improve dietary diversity and health outcomes.

The majority of our grain consumption—over 70 percent—is wheat-based. Whole grain consumption, in general, is quite low, with the average person consuming less than one serving of whole grains per day. Alarmingly, only nine percent of children meet the recommended three servings of whole grains daily. This highlights a critical gap in nutritional intake that could be bridged by incorporating more rye and barley.

Rye and barley are not only nutritious but also offer practical benefits for food producers. These grains are resilient, with the ability to thrive and be preserved even in adverse conditions such as drought or cold climates. This makes them a reliable resource for food production, ensuring a stable supply chain.

Consumers stand to gain considerably from increasing their intake of rye and barley. These grains are rich in dietary fibers, which promote digestive health and can help prevent diseases such as type 2 diabetes and cardiovascular conditions. They also contain essential minerals like magnesium, potassium, selenium, manganese, iron, and copper, along with B vitamins and numerous other micronutrients crucial for maintaining good health.

Despite their benefits, current consumption levels of barley and rye remain low. However, there is potential for change. These grains can be used flexibly across various food products, either alone or in combination with other grains, to enhance the nutritional value and variety of whole grain foods. Food manufacturers can innovate by integrating rye and barley into their product lines, offering consumers healthier and more diverse options.

In conclusion, while barley and rye are currently underutilized compared to major cereals, they present an untapped opportunity for both producers and consumers. By promoting and incorporating these nutritious grains into more food products, we can improve public health outcomes and create a more resilient and diverse food supply. As awareness grows, the future holds promise for these 'minor' cereals to play a more significant role in our diets, contributing to a healthier population and a more sustainable food system.

Ancient grain - Farro

Farro (Triticum dicoccum) is an ancient grain that dates back 17,000 years to the beginning of agriculture in the Fertile Crescent in Mesopotamia. Farro looks similar to barley, though with a slightly more oblong and larger grain.

With a similar texture to rice, it can be found in many Mediterranean, Ethiopian and Middle Eastern dishes and is a great protein substitute for vegans and vegetarians.

It’s packed full of fiber, protein, vitamins, minerals and antioxidants. A half cup of farro contains as much as 8 grams of fiber and protein; a 45-gram serving of pearled farro provides 150 calories, most of which are carbohydrates.

Farro is rich in B vitamins and magnesium, which can help fight period pain, depression, and insomnia. Farro also contains antioxidants such as carotenoids, polyphenols, and selenium.

Before it’s cooked it looks similar to wheat berries, but afterward it looks similar to barley. It’s a small, light-brown grain with a noticeable outer layer of bran.

Farro is loved for its nutty flavor and unique, chewy texture. Farro can be milled into flour or cooked like rice and added to soups, salads, and casseroles. It is known to be the best substitute for arborio rice when making risotto.

Biofortification of barley

Nowadays, micronutrient deficiency, also known as hidden hunger, is one of the major challenges to human health worldwide.

Biofortification is a good option where the nutrients are increased in the grain itself using agronomic, genetic, or biotechnological interventions. Biofortification of staple crops has been broadly accepted as the best strategy to overcome these limitations.

Barley is considered one of the most important cereal crops, along with rice, corn, and wheat. The cultivation of barley has a large distribution worldwide and it ranks fourth both in production quantity and cultivated area among grain crops.

Barley is gaining attention as a functional food because of its medicinal value in reducing the risk of a number of health problems. It is a very good source of soluble fiber and the nutritive value is similar to the major cereals.

There is need to biofortify barley with minerals (iron, zinc, and selenium), vitamins, essential amino acids, and bioactive compounds with health beneficial activities.

Barley being a model cereal crop has been targeted to improve its micronutrient content. Ferti-fortification (biofortification through fertilization) in barley is mainly focused on the increase of bioavailable Zn and Fe content in grains, which are considered the major mineral deficiencies worldwide.

Its zinc content has been improved by overexpression of zinc transporters. The expression of DHPS and phytase gene causes an increase in lysine iron and zinc bioavailability in barley.

Essential amino acid lysine has been enhanced in barley by expressing DHPS gene [dapA]. β glucans content has been increased in barley by overexpression of cellulose synthase-like gene [HvCslF].

Barley biofortification aims at developing micronutrient rich cultivars using conventional plant breeding along with advanced biotechnological approaches and agronomic practices and is considered to be the most economical solution to human micronutrient’s deficiency.

Other methods of barley biofortification - Genetic Biofortification: through breeding and genetic engineering.

Biofortification of staple crops, such as cereals, is a successful approach for dealing with micronutrient deficiencies worldwide. Over the last decades, great achievements have been made in this direction, especially for crops like wheat and rice.
Biofortification of barley

Barley: Cultivation and harvesting

There are two types of barley seed stock commonly available: malting and feed varieties.
*Malting varieties: Must meet rigorous standards for germination quality, kernel size and weight, kernel plumpness, and moisture content.
*Feed varieties: Varieties that do not meet malting industry standards

A moderately cool and dry climate is most suited to barley. Although barley is able to withstand heat in a dry climate or high humidity in a cool climate, it performs poorly in a hot and humid climate.

Barley is a drought resistant crop and requires 390 to 430 mm of rainfall for optimum yield. As barley is sensitive to nitrogen and water hence, field should be well leveled.

Barley cannot tolerate poorly drained soil, grows well when pH values are between 6.0– 8.5. It generally grows better than any other small grain in highly alkaline soils. Best soils for growing barley are well-drained loams and clay loams.

Soils with a pH lower than 6 may induce aluminum toxicity, leading to poor growth. Barley is more sensitive to very wet conditions but more tolerant to alkaline soil than the other small grains.

In irrigated areas, field should be prepared after pre sowing irrigation for proper germination.

Barley can be grown under irrigated, rainfed and limited irrigation conditions. Generally, it requires 2-3 irrigations for better yield. The malt barley requires 3 irrigations to ensure better yield, grain uniformity and grain quality.

After physiological maturity, 10 or 15 days are required to harvest barley in temperate dry lands. Harvesting time should be decided when barley stem becomes dry enough to be broken by hand easily in semi-arid and arid areas.

In general, barley is ready for harvest in about 4 months after sowing; some varieties in 60 days. It should be harvested as soon as it reaches the moisture content of 13 %.

Seed is harvested mechanically with a combine and thresher. Seed harvested for use in the malting industry must be harvested with care, as cracked or skinned seeds are not acceptable to industry standards.

Barley grain absorbs water from the atmosphere and should be stored at an appropriate dry place to avoid storage pest losses.

β-glucan in barley

It is thought that barley cultivation began 8000–10 000 years ago in the ‘Fertile Crescent’ of the Middle East and thus barley has been considered to be one of the founding crops of Old World agriculture.

The active ingredient thought to provide barley its health benefits is β-glucan. β-Glucan is a plant cell wall polysaccharide that is found in a range of tissues in barley including the grain, where it constitutes approximately 70% dry weight (w/w) of endosperm primary cell walls.

β-Glucan is a type of soluble fiber, linear homopolysaccharides composed of D-glucopyranosyl residues linked via a combination of β-(1→4) and β-(1→3) linkages.

This polysaccharide accumulates throughout barley endosperm development. β-glucans are predominantly found in the internal aleurone and subaleurone cell walls. The content of β-glucan varies with environmental conditions during endosperm development and is regulated by (1 → 3,1 → 4)-β-glucan endohydrolase to facilitate endosperm cell-wall degradation during germination.

Of cereal grains, oats and barley contain the highest level of β-glucan at 3–7 and 3–11% (dry weight basis), respectively.

Its beneficial role in insulin resistance, dyslipidemia, hypertension, and obesity is being continuously documented. The fermentability of β-glucans and their ability to form highly viscous solutions in the human gut may constitute the basis of their health benefits. Among the dietary fiber sources, cereal β-glucans have been shown to be one of the most effective fiber types to prevent type 2 diabetes and cardiovascular diseases.

Fiber in barley may bring blood pressure levels down

Blood pressure is the strength of blood pushing against blood vessel walls. It is measured in millimeters of mercury (mm Hg). The individual who have high blood pressure (HBP) means the pressure in his arteries is higher than it should be.

The general beneficial physiological effects of consumption of whole grains include reduce in blood pressure which may reduce risk of stroke.

Barley plays a vital role in health and civilization of human migration from Africa to Asia, later to Eurasia. Barley is a good old grain with so many health benefits like weight reduction, decreasing blood pressure, blood cholesterol, blood glucose in Type 2 diabetes and preventing colon cancer.

Barley contains soluble fiber, β -glucan binds to bile acids in the intestines and consequently decreasing plasma cholesterol levels. Absorbed soluble fiber reduces cholesterol synthesis by liver and cleansing blood vessels.

Regular daily consumption of whole barley flour can prevent high blood pressure. Higher consumption of barley β-glucan has been linked with lower systolic and diastolic blood pressure.

β-glucans can interact with intestinal lipids and bile salt to reduce cholesterol levels and subsequently prevent chronic diseases such as diabetes, hypertension, cardiovascular disease, and metabolic syndrome.
Fiber in barley may bring blood pressure levels down

Antioxidants in barley grain

Barley (Hordeum vulgare) is a widely consumed cereal. Barley was one of the first agricultural domesticates together with wheat, pea, lentils dating from about 10,000 years ago.

Antioxidants in grains may play an important role in the chronic disease prevention by arresting oxidative damage caused by reactive oxygen species (ROS) to vital biomolecules such as DNA, lipids, and proteins.

Barley is gaining renewed interest as an ingredient for production of functional foods due to its high contents of bioactive compounds such as β-glucans, tocopherols and tocotrienols.

Epidemiological studies have associated the regular consumption of barley with its potential to reduce the risk of certain diseases, such as chronic heart disease, colon-cancer, high blood pressure, and gallstones.

Moreover, there are many classes of phenolic compounds in barley and their high content of phenolic compounds such as phenolic acids (benzoic and cinnamic acid derivatives), proanthocyanidins, tannins, flavonols, chalcones, flavones, flavanones, and amino phenolic compounds.

The flavanols, such as catechin, procyanidins and prodelphinidins are the predominant compounds of barley phenolic extract in the free form, while phenolic acids, such as ferulic, sinapic and coumaric acids, mainly exist in bound form.

The abundant content of phenolic compounds in barley reveals that it may serve as an excellent dietary source of natural antioxidants with antiradical and antiproliferative potentials for disease prevention and health promotion.

Many researches suggest that these phenolic acids are absorbed in humans and that their antioxidant activity may reduce the risk of coronary heart diseases, cancers, and the aging processes.

Among all cereals, barley is the richest source of tocols, which consist of tocopherols and tocotrienols. Studies have indicated that α-tocotrienol is a more effective antioxidant than α-tocopherol, but it is less bioavailable after oral ingestion, when both ingested.
Antioxidants in barley grain

Nutrient in barley grain

Cultivated barley, Hordeum vulgare, is mainly grown for animal feed, for malting and brewing in the manufacture of beer and for distilling in whisky manufacture.

Studies have associated the regular consumption of barley with its potential to reduce the risk of certain diseases, such as chronic heart disease, colon cancer, high blood pressure and gallstones.

Whole grain barley has high levels of dietary fiber (14.8 g/100 g raw material) and good levels of other bioactive compounds, vitamin B and E and also minerals, such as iron (6 mg/100 g raw material), zinc (3.3 mg/100 g raw material), and calcium (50 mg/100 g raw material).

Due to its high viscosity in aqueous media, the soluble cell wall polysaccharide (1→3),(1→4)-β-glucan is an important nutritional component. β-glucan play a pivotal role as nutraceutical food in preventing cardiovascular diseases, controlling diabetes mellitus, regulating cholesterol level in body.

Barley is a good source of dietary phenolic compounds, which can be found free as well as bound to fiber. The flavanols, especially catechin, procyanidins and prodelphinidins, are the main compounds in the free phenolic fraction of barley grain.

Barley has a significantly higher protein content (10–20%) compared to corn (9.5%), rice bran (10–16%), and wheat (14%). The storage proteins in barley grains belong to two solubility classes, namely globulins (a fraction soluble in dilute salt solutions) and prolamins (a fraction soluble in aqueous alcohols).

Barley protein contains essential amino acids and is characterized by desirable functional properties (such as elasticity, water holding, and emulsifying capacity), which makes it an ideal component of food supplements.

Barley protein is rich in prolamin storage proteins (hordeins) and has moderate nutritional quality, being particularly deficient in lysine. These hordeins are not single proteins but complex polymorphic mixtures of polypeptides. β-hordein is the largest fraction accounting for between 70 and 90% of the total hordein content, and it is the major storage protein of the barley grain. β-hordein can be further broken down into subunits B1, B2 and B3 based on their electrophoretic capabilities.

The increase of protein content is accompanied by decreases in essential amino acids, mainly lysine. It was suggested that nutritional quality of the grain decreases with increasing grain protein contents as an increasing proportion of the nitrogen is incorporated into prolamin storage proteins.

The other barley proteins consist of a mix of albumins, globulins and glutelin. Globulins cover 10–20% of the total protein content of barley grains.

General history of barley

Barley cultivation probably originated in the highlands of Ethiopia and in Southeast Asia in prehistoric times. It is believed to extend back to 5000 BC in Egypt, 3500 BC in Mesopotamia, 3000 BC in north-western Europe, and 2000 BC in China. Barley was grown on the Korean Peninsula by 1500-850 BC along with millet, wheat, and legumes. Six-rowed barley did not come about until after 6000 BC.

Barley played an important role in ancient Greek and Roman cultures as a staple bread-making grain as well as an important food for athletes. Gladiators were known as Hordearii, meaning ‘eaters of barley’. The use of barley grains in social and religious ceremonies by Hindus, Greeks and Romans illustrates its antiquity.

The first barley foods probably were simple. The kernels were eaten raw until the discovery that removal of the hulls of hulled types followed by soaking and/or cooking in some manner enhanced the texture and flavor.

In ancient Egypt (3200 BC to 30 BC) barley bread and beer (made from malt) constituted a complete diet. A clay tablet from ancient Sumer in Lower Mesopotamia dating from around 2700 BC provides a prescription for a poultice that includes dried powdered herbs and fruit blended with barley ale and oil.

Barley was the chief bread plant of the Hebrews, Greeks, and Romans and of much of Europe through the 16th century.

In New World, barley, together with other English grains, was grown in 1602 by Gosnold on Martha's Vineyard and the Elizabeth Islands off the south coast of Massachusetts, and by the colonists of the London Company in Virginia in 1611.

Barley was first grown in Mexico and was introduced there by the Spanish conquerors.

Today, barley is the fourth largest grain crop after wheat, rice and corn. It is still grown in many different countries throughout the world.
General history of barley

Prolamin in barley

Prolamins are the endosperm storage proteins of cereal grains. The prolamins are monomeric polypeptide chains with molecular weights between 30 to 80 kDa depending on the type of cereal. They are rich in proline and glutamine (20 - 55 %).

Prolamins present different names depending on the type of cereal from which are extracted. Prolamins in wheat which are known as gliadins, in barley as hordeins, in rye as secalins, and in oats as avenins are main triggering factor in celiac disease.

Barley prolamins are the main storage protein in the grain, and major protein in barley by-product. The barley prolamins, hordeins as the main storage protein fraction in barley seeds constitute approximately 50–80% of total grain proteins.

Hordeins accumulate in the starchy endosperm cells of developing barley grains, during grain filling. Hordein synthesis proceeds linearly from approximately 10 to 30 days post-anthesis.

Four sub-units are classified based on their electrophoretic mobilities, B-hordein of 35–46 kD, C-hordein of 55–75 kD, γ-hordein of less than 20 kD and D-hordeins of more than 100 kD.

B-hordein consists in the major fraction of hordein (70–80%) and are sulfur-rich. C-hordein it is the second most important fraction (10–20%) and are sulfur-poor. D-hordein considered a protein with high molecular weight (HMW) and γ -hordein (1%–5%) with the smallest polypeptides.

Scientists study the effect of B, C and D hordeins on malting quality of northern European barleys and found that the B fraction had some effect on malting quality through changing adjusting diastatic power.

The hordeins are amongst the triggers of coeliac disease (CD), a well characterized T-cell mediated disorder suffered by approximately 1% of most populations. In coeliac disease the immune system mounts an inappropriate reaction to particular peptide sequences in dietary gluten, reacting as if the gluten molecules were an invading microorganism.
Prolamin in barley

Barley: Excellent source of fiber

Barley (Hordeum vulgare L.) is the fourth most important cereal crop, after maize, wheat and rice. Barley has been cultivated for at least 8,000 years. It is believed by most, though not all archeologists to have been first cultivated in the Fertile Crescent, an area that includes parts or all of what is presently Iraq, Iran, Israel, Syria and Turkey.

Barley is known to be a rich source of ß-glucan soluble fiber. While most other grains have lower fiber in the endosperm than the whole grain, the soluble ß-glucan in barley endosperm is comparable to that of whole grain. Whole barley grain consists 4% to 9% B-glucan.

There is strong evidence that barley β-glucans can lower blood cholesterol levels, thereby reducing the risk of coronary heart disease. Both Canada and the U.S. allow manufacturers to make a heart-health claim for foods containing barley. Fiber content Β-glucan also has been shown related to weight reduction, decreasing blood pressure, and blood glucose in Type 2 diabetes and preventing colon cancer.

Besides its high level of β-glucan soluble fiber, barley is an excellent source of insoluble fibre important in maintaining digestive health and also protecting against colon cancer.

Total dietary fiber ranges from 11% to 34% and soluble dietary fiber from 3% to 20%. Hull-less or de-hulled barley grain contains 11% to 20% total dietary fiber, 11% to 14% insoluble dietary fiber and 3% to 10% soluble dietary fiber.

Barley: Excellent source of fiber

Malting barley for brewing

Malt barley is one of the principal ingredients in the manufacture of beer. Brewers can either purchase malt barley to manufacture malt themselves or purchase malt from malting companies.

Malting of the barley grain to produce pale malt involves the imbibing of the barley with water (steeping) to a moisture content of 42–46%, a period of metabolic and physiological activity after germination and finally kilning with increasingly hot air to dry the malt to approximately 5% moisture, thus ceasing metabolic activity.

Malting is defined as the controlled germination of cereals, to ensure a given physical and biochemical change within the grain, which is then stabilized by grain drying. It is a process of forced germination, conducted in order to degrade starch molecules and to obtain certain levels of amylolytic and proteolytic enzymes which are important in brewing.

Three process steps are necessary to ensure that these changes occur:
*Steeping, to ensure good absorption of water by the grain (from 12% to at least 40% of moisture);
*Germination, to maintain embryo growth, enzyme synthesis and a limited endosperm breakdown; and
*Kilning, to ensure product stability.

Malting ensures the accumulation and release of a number of malt enzymes that degrade starch (αamylase, β-amylase, limit dextrinase, and α-glucosidase), cell wall non-starch polysaccharides (β-glucanase and xylanases), lipids (lipase and lipoxygenase), and enzymes that degrade and release proteins (endo-proteinases and exo-proteinases).
Malting barley for brewing

Fibre components in barley

Barley is a great choice for health-conscious consumers who care about where their of food comes from.

As one of the first domesticated grains, barley was major source of fibre and nutrients in the human diet.

Barley fibre provides a unique balance of soluble and insoluble fibres distributed throughout the a mature seed. A barley seeds produces fibre in the hull, pericarp, and the cell walls of the aleurone and starchy endosperm.

Fibre from these anatomical sources differs in composition. Barley products may improve glycemic control in diabetic populations. Barley breads improved glycemic response in fifteen patients with well-controlled type 2 diabetes.

As indicates by Agriculture and Agri-Food Canada indicates that the daily consumption of three grams of barley beta-glucan, a type of soluble fibre assiststs in lowering cholesterol, which is a risk factor for heart disease.

According to Health Canada’s specifications for claims made on food labels, foods containing a minima of one gam of beta-glucan from barley grain products can be said to meet 35& of the daily requirements.

In 2006, barley join oats in an improved health claim for reducing the risk of cardiovascular disease (FDA 2006). Soluble finer as found in barley has proven effective in reducing cardiovascular risk by reducing serum cholesterol when consumed regally and in small but adequate amounts.
Fibre components in barley

Ancient history of barley

Archeological evidence indicates that the wild barley was growing in the ancient past in Fertile Crescent 35,000 – 40,000 years ago.

About 9000 BC, the Natufians, who had a Mesolithic culture, gathered and used wild grains.

The Egyptians have a tradition that barley was the first of the cereal mad use by a man and trace its introduction to their goddess Isis.

Sumerian clay tablets described and recommended cultural practices for raising barley around 1700 BC. Barley was an important crop throughout the Neolithic period and the Bronze Age.

It is one of ancient crops in India. It was widely consumed as human food and horse feed in early time, particularly by Aryans.

According to experts, six rowed barley which was being grown in the Indus Valley at Mahenjo-daro and Harappa by about 2500 BC, was almost certainly introduced for Mesopotamia.

In Europe, as early as 3000 BC, barley was a stable food utilized in various types of breads and cakes throughout Europe, especially in the British Isles and Scandinavian.

Barley remained a stable ingredient in porridges along with peas and oats in the British Isles but often was the only cereal ingredient in Scandinavian porridge and stew recipes up until early in the twentieth century. 

Barley was first grown in North America in 1492 by a colony founded by Columbus. Spaniards introduced barley into Mexico during the conquest, and from there it was introduced by missionaries into California.
Ancient history of barley

Barley malt

Barley is a member of the Gramineae. It is cultivated primarily for its grain which is used for human and animal food.

Malted barley has been extensively used for brewing purposes. The first stage in the malting process is to sprout the grain.

Malting is the process which cereal grain, predominantly barley is soaked and germinated under controlled conditions to activate the natural amylase of the grain. This in turn hydrolyses the starch producing mainly the disaccharide sugar maltose with some dextrins and other sugar.

After barley is malted, it is coarsely ground then extracted with hot water. This step is called mashing, where the ground malt is mixed with water and heated to about 70° C.

Syrups of barley malt extract are deliciously flavored and sweet as well as being enormously nutritious. Barley malt extracts are rich in soluble fiber in the form of gummy beta-glucans, which offers many health benefits.

They are sweet with malt sugar derived from the starch by the enzymes.

Barley malt is the most important grain product used by brewers worldwide, and many countries import virtually all of this ingredient need for their beer production.

Barley Health Benefits

The major nutritional components of the mature kernel are carbohydrates (starch, sugars, and fiber), protein (amino acids), lipids (fatty acids), and ash (minerals).

The chief benefits of barley is provided by its fiber components. Like oat bran barley’s dietary fiber is high in beta-glucan, which helps lower cholesterol by binding to bile acids and removing them from the body via the feces.

The soluble fiber also helps manage blood glucose.

Barley is excellent food for the anemic and nervous on account of its richness in iron and phosphoric acid.

In Neolithic times the grain was cooked, crushed and pounded into a nutritious milk that built strong bones – barley is now recognized to be important for osteoporosis due to its high calcium and potassium content.

It is also useful in fevers and all inflammatory diseases, on account of its soothing properties. From the earliest times barley water has been the recognized drink of the sick.

In cooking barley meal is best used as a thickening base for soups. Barley meal may also be added to soups to thicken them. Races that lives on barley are noted for their health and vigor.
Barley Health Benefits

Carbohydrates in Barley

Starch
Starch is a polysaccharides, alpha-glucan and can be divided into straight-chain amylase and branched chain amylopectin.

The starch granules in the barley endosperm are laid down within amyloplasts and fall into two size groups: 1,7-2.5 um and 22.5 – 47.5 um.

These starch granules contain traces of lipids, minerals, protein and nucleotide.

The “diastatic” enzymes responsible for degrading the starch in germination are phosphorylase, alpha glucosidase, alpha-amylase, beta-amylase, debranching enzymes, and transglucosylase.

These starch in the endosperm is 95% deposited in 11-28 days after ear emergence and the ratio of amylopectin increases to the final ratio.

In normal barleys the ration of amylase to amylopectin is about 1:3, in high amylase Glacier about 1:1 and waxy barley is 97-100% amylopectin.

Soluble sugar
At least nine monosaccharides and seven closed related compounds occur in barley. Glucose and fructose are found free and in combination, whereas, other monosaccharides are polymerized as oligosaccharides, polysaccharides, glycosides, glycolipids and glycoproteins.

Soluble sugar content of normal barley is about 2-3%, hulless barleys 2-4%, high lysine barleys 2-6%, and high sugar barleys 7-13%.

The total sugars and reducing sugars decline from anthesis to maturity, whereas non-reducing sugars are constant in amount during plant growth.

The major sugar found inviting tissues of barley is sucrose.

Nonstarch Polysaccharides
Polysaccharides can be defined as “pectin fraction” hemicellulosic materials, which are then divided into gums of soluble in hot water and hemicellulose.

The material remaining after delignification and removal of gums and hemicellulose is termed “holo-cellulose.” Endosperm gums consists of beta-glucan and an arabinoxylan.

Endosperm cell walls in barley are unique in cereals, since they completely enclose the cell forming barriers to proteolytic and amylolytic enzymes.

Some of the polysaccharides are linked to phenolic acid and some to lignin. The dietary fiber of barley is comprised of the nonstarch polysaccharides, resistant starch, and lignin.
