NUTRITIONAL VALUE AND SAFETY OF COW MILK FROM FARMS ADJACENT TO THE IMPACT AREAS «PROTON-M» LV

Abstract

The article presents the results of nutritional value and safety of cow milk from farms adjacent to the impact areas of «Proton-M» LV in Ulytau district of Karaganda region. The authors have found that in the cow milk samples from the risk zone (wintering: "Togyzbay", "Almenbet", "Zhanadyl", "Zharyk",), there was a significant decrease in the concentration of amino acids (from 4.7 to 26,%, the sum of amino acids 12, 2%, the ratio of essential amino amount to nonessential acids is 0.89, amino acid score was minimal for methionine - 68%, phenylalanine - 85.4%), the concentration of vitamin composition (vitamin B1 by 21.25%, vitamin B2 by 38.6% ,
vitamin B12 by 47.3%, B6 by 48.4%, vitamin C by 40.3%); concentration of macromicroelements (magnesium by 17.2%, zinc by 22.3%, molybdenum by 26%, copper by 30%, iron by 37.4%, manganese by 35%); the concentration of saturated fatty acids (myristic by 31.2%, palmitic by 38.5% stearic by 45.2%). In general, it should be noted that cow milk from the risk zones had low values for amino acid, vitamin, mineral and fatty acid composition compared to those from safe zones.
