Development of an isotonic drink enriched with whey protein isolate and vitamin premix

Dairy products have proven beneficial properties and are in stable demand among the majority of the country's population. In total, there are about 5.4 thousand enterprises processing milk and manufacturing dairy products in Russia, which determines the real high demand for products in this segment. The article presents the developed recipe and technology for the production of an isotonic drink based on whey enriched with protein isolate and vitamin-mineral premix. The beneficial properties of whey protein and vitamin premix and their beneficial effects on the human body are considered. The effect of added fortificates on the food, including physiological and biological value of the developed product is studied. Drinks with different concentrations of biologically active components obtained using the developed technology are studied. Based on the results of organoleptic evaluation and physicochemical studies, the most acceptable variants of suitable drink samples for further research were selected. The samples in their composition have high concentrations of biologically active substances (essential amino acids, vitamins), which will ensure a positive effect on the human body with systematic use of the developed isotonic drink. The selected dosage of the drink in the volume of 250 ml and the active substances in it was chosen based on the consumption of the drink after high-intensity physical activity, to restore the water-salt balance, as well as the state of muscle tissue due to the presence of complete protein in the product. A modified machine and hardware scheme to produce an isotonic drink enriched with whey protein isolate and vitamin premix is presented. Thus, the development of drinks fortified with bioactive components is resource-efficient and practically feasible.
