Abstract
The objective of this paper was to study the amino acid composition of donkey milk inhabiting the Kegety gorge of the Chui region. As well as human milk, donkey and mare’s milk is albumin; the amount of casein is 35-45%, while cow’s milk is casein milk with casein content over 75%. The peculiarity of albumin milk is a higher biological and nutritional value, due to better amino acid balance, high sugar content and the ability to form small, delicate flakes when souring. In terms of its properties, albumin milk is closest to human milk and is the best substitute for it. The obtained results showed that the quantitative content of 7 essential amino acids out of 8, such as lysine, phenylalanine, leucine, isoleucine, methionine, valine, threonine is relatively high compared to other amino acids. Despite the absence of tryptophan in donkey milk, the percentage of 8 essential amino acids in donkey milk protein exceeds that in mare and cow’s milk.
Highlights
The popularity of donkey milk, with its functional properties, is of great interest in Europe and is being studied by scientists in China and Italy
It is known that the Queen of Ancient Egypt Cleopatra, famous for her stunning beauty, took baths filled with donkey milk
Georges-Louis Leclerc, Count of Buffon (1707-1788) was of a similar opinion. He mentions the benefits of donkey milk: “the miraculous properties of donkey milk were widely used in Greece, no data on this have been saved, but it really was one of the remedies for the treatment of certain diseases.” [2]
Summary
The popularity of donkey milk, with its functional properties, is of great interest in Europe and is being studied by scientists in China and Italy. The second wife of Emperor Nero, Poppaea Sabina, followed this ritual, which Pliny described in his writings He said that donkey milk “erases wrinkles on the skin,” preserves tenderness and bleaches (whitens) it. Food proteins are split down to amino acids, a certain part of them is split up to organic keto acids, from which new amino acids are again synthesized in the body, and proteins needed by the body. These are the so-called nonessential amino acids. The content of amino acids in donkey milk during the lactation period (days) [9]
