Abstract

To provide the population with high-quality milk and dairy products, to increase the production of milk fat, protein, carbohydrates and other substances, it is necessary to take measures to improve the chemical composition of milk. The article presents the results of research on the composition and properties of different portions of cow's milk of morning and evening milking. It was found that the composition of milk is different and depends on the portions. The mass fraction of protein, lactose, salt, skimmed milk solids is high in the milk of the first portion, the mass fraction of fat and milk solids is high in the last portion. The milk density of the first portion is maximum, and the last portion is minimal. It was found that depending on the portions, the composition of morning milking milk changes more than the composition of evening milking milk.
