Over the past 20-30 years, the consumption of milk and dairy products in Russia has been steadily declining. An online survey was carried out to find out the reasons for this. The questionnaire was created on the Yandex forms platform with automatic counting of answers.

[Analysis of amino acid composition of skim milk and buttermilk for the production of dairy drink when introducing whey protein hydrolysate].

The imbalance of macronutrient composition of people's diets determines the relevance of the functional foods development - sources of protein and essential amino acids. of the work was to analyze the amino acid composition and determine the functional significance of the product based on skim milk and buttermilk byadding whey protein hydrolysate. .

[Recipe and application of new oxygen cocktail with high protein content in nutrition of cardiological patients].

The aims of this study was to develop recipe composition and to evaluate the use of new oxygen cocktail with high protein content in the dietary therapy of cardiological patients. Objects of the study were: the control sample - an oxygen-containing product prepared using dairy whey, fruit and berry juice, highly esterified pectin; experimental samples - oxygen-containing products, which differed from the control sample by additional introduction of whey protein hydrolysate. Experimental samples have been modified by adding to them whey protein hydrolysate in the amount of 1-3% from the total weight of composition.

[Content of mineral elements in the diet of students of physical education faculty].

Research of the diet of students of the Faculty of Physical Education found discrepancy of caloric content and correlation of macro- and micronutrients to physiological norms accompanied by a deficiency of some mineral elements. Thus, this research found discrepancy of a diet in caloric content and correlation of macro- and micronutrients to physiological norms. Calorie deficiency in both groups is caused for lack of all macro- and micronutrients, but mostly for lack of carbohydrates with an average glycemic index, fruit, and vegetables that have prebiotic properties and mineral-rich elements.

[Medical and biological basis of the recipe of cultured milk products-containing rehydrating beverage for the athletes].

According to the results of the physic-chemical research the composition of new isotonic rehydrating beverage has been presented and its nutritional and energy value has been calculated. As opposed to other sport drinks of this kind, a part of water in the new product is substituted by whey. From the physic-chemical standpoint whey is a complicated dispersed system in which hydrated proteins are in the form of colloidal solution, lipids are finely emulsified lipoprotein particles, carbohydrate and mineral components are close to the composition in the whole milk.
