Whey as a multicomponent system obtained after partial extraction of fats and proteins from milk, contains carbohydrates, vitamins, minerals and proteins, which include essential amino acids. That is, whey can be considered as a component of mass consumption products, the composition of which includes physiologically functional ingredients capable of causing positive biological changes to the human organism. In order to comprehensively and systematically estimate the value of all whey components, it is necessary to consider them within the framework of the nutritional value concept. The nutritional value of the whey was analyzed and its significant potential in the production of physiological-functional products was revealed. It has been established that the energy value of whey is appropriate for the organization of rational nutrition according to certain types of diet, in particular for weight loss and sports orientation. The results of whey biological value analysis are presented, which indicate its high level, which is due to a wide range of fractional protein content, amino acid composition, phospholipid content, high lactose content, a wide list of vitamins, as well as a significant content of macroelements. It has been established that the physiological value of whey can be characterized as complex, which is due to a wide range of positive effects for the systems of the human organism, in particular cardiovascular, digestive, immune, nervous, sexual and locomotor, aswell as due to a resistance to infectious diseases. It was also established that whey is physiologically active and has the ability to autolyze in the human stomach, which, from the point of view of the adequate nutrition theory, indicates its high value. It is proposed to recommend whey for the production of infant formula, as well as for the production of physiological-functional purpose products in the systems of the hotel-restaurant economy at all.
