The cells of the aleuron layer contain a dark-cut substance containing protein, fats, mineral salts, vitamins and enzymes. Aleuron cells do not contain gluten proteins. These proteins occur in Kidowy, mainly in the outer layers. The closer to the grain, the more starch and less proteins. The middle whiteness performs the function of the grain spare tissue. Depending on the content of the structure, Bielmo can be glassy or flourish. Bielmo vitreous is darker than the flour and with some transparency. Vitreous beans generally have a bielmo hard, Flour grains - soft. Of the varieties of wheat grown in Poland, glass grains have more protein than the meal grains (including the decisive value of the so -called. baking flour - gluten). Only in the brewing, flour barley is more wanted than a glassy. The cover is formed by the enemy of the fruit coat formed from the walls of an octophae with a seed cover formed from the walls of the germ. The cells of this layer contain various color compounds, from which the grain color comes from. The condition of the cover and the percentage of its weight in relation to the grain is a very important indicator of grain education in the process of cereal growth. In the barley grain, the pot is fused with a fruit cover, while in oats, rice is not attached and can be relatively easily separated.
The chemical composition of grain grain can be significantly fluctuated, Depending on the species and variety, growth conditions, harvest time, storage conditions and in. Cereal grain includes sugar, proteins, fats, Inorganic relationships (water, mineral salts) vitamins, enzymy i in.
The size of this study does not allow for a more detailed discussion of the characteristics of individual types of cereals. So we discussed the most known and most used raw materials of vegetarian diets, from cereals.
