[Efficiency of vitamin D deficit correction depending on rats' supply with B vitamins].

Despite the presence of combined deficiency of vitamins D and group B among the population of Russia, the intake of cholecalciferol is often recommended without correcting the supply with B group vitamins, which are involved in ensuring the biological functions of vitamin D. of the study was to compare the effectiveness of vitamin D deficit correction by replenishing its content in the diet to an adequate level without eliminating the deficit of B vitamins and by restoring vitamin D level in combination with B vitamins. .

[Ways of nutritional value increasing of distillary grain fiber].

In the process of grain processing for ethyl alcohol, practically only carbohydrates are consumed, which are presented mainly in the form of starch. The remaining components (protein, fats, fiber, minerals) in transit pass into the grain fiber remaining after distillation of the alcohol from the mash. Distillery grain fiber surpasses wheat bran in its indicators, since during the processing it is enriched with biomass of alcohol yeast.

[Biological value of fruits and berries of Russian production].

Fruits and berries are the most important sources of a wide range of biologically active substances, including vitamin C, carotenoids, flavonoids, anthocyanins. In order to replenish and update data on the content of food and biologically active substances in the tables of the chemical composition of food products, a study of the content of mono- and disaccharides, dietary fiber was carried out; vitamins C, B1, B2 and E, minerals and trace elements; flavonoids (in terms of rutin), anthocyanins; organic and hydroxycinnamic acids, stilbenoids in various varieties of 16 fruit and berry crops. .

[Databases of the chemical composition of foods in the era of digital nutrition science].

By studying the chemical composition of foods, expanding the list of data on the content of nutrients, including minor biologically active substances, in the era of digital nutrition science, it became possible to create relevant systematic databases of the chemical composition of foods and rations in general. They allow us to solve various problems of modern society from the point of view of nutrition science. This review to analyze and generalize modern approaches to the formation and updating of databases of the chemical composition of food products from the standpoint of digital nutrition science.

[Nutrient value of fruit in promising strawberry varieties].

One of the current areas in research of fruit and berry crops is the study of their nutritional value and micronutrient composition. Valuable chemical composition of the strawberry determines a wide spectrum of its utilization not only as fresh fruit, but also as a raw material for food industry. Breeding requirements for contemporary strawberry varieties together with yield, large-fruit, important taste and dietary qualities of fruit provide for higher content of biologic active substances.
