Milk-containing products with reduced antigenicity

Бесплатный доступ

Whey containing more than 50% of milk solids can be attributed to an insufficiently demanded raw material of the dairy industry. The restriction of its usage for food purposes is the high residual antigenicity of whey proteins. This work aimed to justify the possibility of using milk-containing products with whey protein hydrolysate, characterized by reduced residual antigenicity, in healthy and dietary diets. Experimental work was carried out at the All-Russian Scientific Research Institute of Dairy Industry, the Animal-Derived Food Technology department and the Core Facilities Centre "Control and Management of Energy-efficient Projects" at the FSBEI HE VSUET. Compositions were developed for a sports nutrition drink made from whey protein hydrolysate with the addition of fructose, and a milk-containing drink with the replacement of 30% skimmed milk necessary for standardization with whey protein hydrolysate. The chemical composition, physical, chemical and microbiological properties of the finished products were established. The reduction of the true protein content was proven to 1.33% for a sports nutrition drink and to 1.69% for a milk-containing drink. Peptides and proteins in the finished products have a molecular weight of less than 10 kDa, which indicates a decrease in their potential antigenicity. The developed beverages are characterized by a high content of biologically active peptides, macro- and microelements, as well as vitamins. Their quality and safety indicators meet the requirements of the TR CU 033/2013. These products can be used as part of dietary diets for people who are allergic to cow's milk proteins. The organization of their production will contribute to import substitution in the segment of low-allergenic dairy products.
