Abstract

Wheat is a plastic crop and therefore occupies a huge area, spreading in the north to the cold pole (Verkhoyansk), and in the south - to the border of cultivation of cultivated plants. In some regions of Azerbaijan, it is sown in fields below sea level, and in Peru, it rises in the mountains up to 4000 m. Cultivation of wheat on a huge territory is possible due to the high adaptive properties of the culture, its resistance to frost and drought.Almost half of the bread composition is represented by carbohydrates, in which starch takes the main place (up to 80%). Under the influence of enzymes, it is broken down to simple sugars that the body needs. The total digestibility of bread carbohydrates reaches 90-92%.
