Barley (Hordeum vulgare L.) is generally called “Jau”. It is quite significant cereal after wheat, maize & rice. Barley is cultivated in summer season in temperate area while it is sown in winter seasons in tropical zones. Barley is commonly used in breads, soups, stews, and health products, though it is primarily grown as animal fodder and as a source of malt for alcoholic beverages, especially beer. Barley has a nutlike flavor and is high in carbohydrates, with moderate quantities of protein, calcium, and phosphorus and small amounts of the B vitamins. Because it contains little gluten, an elastic protein substance, it cannot be used to make flour that will produce a porous loaf of bread.
