The analysis amino acid composition of milk of simmental breed cows
Analysis of the biological «value» of food is one of the important directions of modern agricultural science and practice that involves determining the composition of amino acids, especially essential amino acids. To quantify characteristics of the biological «value» of the particular amino acids of protein commonly used amino acid Score. Quality of «food protein» is assessed by comparison it’s of amino acid composition with amino acid composition of the «ideal» of the protein. Amino acid Score calculation performed as follows: the content of each essential amino acid in the «ideal» protein being taken as 100%, and in the test - the percentage of matching. The amino acid composition of milk of Simmental breed cows have been investigated. We have described the sample preparation and method of analysis of the amino acid composition in hydrolyzate of the milk proteins using analyzer with ninhydrin post-column derivatization.
