Concentrated forms of nutrients based on whey: biological safety indicators
Whey is a by-product of the production of cheese, cottage cheese or casein. Whey is used in the production of soft ricotta cheese from goat's milk, as well as in the production of brown cheeses. However, native whey has limited commercial use. A significant problem is the low storage capacity of native whey. To solve this problem, a promising approach is to obtain concentrated forms of whey with low water activity, for example, concentrates and isolates of whey proteins. The aim of the work is to test the serum protein concentrate KSB - UV-80 as a basis for the production of dry protein mixtures similar in purpose to products according to GOST 33933 "products of dietary therapeutic and dietary preventive nutrition. Dry protein composite mixtures". As a basis for the development of the dry protein mixture formulation, we used whey protein concentrate KSB-UV-80 produced by JSC "Molvest", Kalach. A pilot batch of © Г.С. Тихонов, Н.А. Кондратьева, И.А. Глотова, 2020 the experimental mixture was developed under the production conditions of Doctor Hoffman LLC, Voronezh. According to physical and chemical parameters, the developed product was characterized by the following indicators: mass fraction of moisture - 8%; protein - 42.5%; fat - 20.2%; acidity - 22.6%. When assessing the biological safety indicators of a dry protein mixture, standard, arbitration and generally accepted methods were used. It has been established that the processing of native whey by ultra - and microfil- tration methods followed by spray drying allows you to get the basis for dry protein mixtures that meet the requirements of biological safety in terms of a set of indicators. In this regard, the concentrate of whey proteins KSB-UV-80 can be recommended for the production of dry protein mixtures similar in purpose to products according to GOST 33933 "products of dietary therapeutic and dietary preventive nutrition. Dry protein composite mixtures". The target market is children of preschool and school age, including those in organized groups, the elderly, consumers who want to lead a healthy lifestyle and eat a healthy diet, people living in unfavorable environmental conditions.
