HYGIENIC ANALYSIS OF WATER-SOLUBLE VITAMINS IN THE COMPOSITION OF FOODS CONSUMED BY ELEMENTARY SCHOOL STUDENTS

Abstract

This article analyzes the level of availability of water-soluble vitamins in the diet consumed by primary school students throughout the year. The compliance of the daily amount of food consumed was assessed for compliance with the requirements of Sanitary rules and regulations № 0017-2021, and the level of availability of water-soluble vitamins was based on an analysis and assessment of the "Chemical composition of food products".
From the analysis of the diet, it can be seen that the daily diet of schoolchildren does not meet hygienic requirements. The amount of thiamine in the daily diet in different seasons of the year was 0,96-1,14 mg, and vitamin riboflavin 0,7-1,2 mg, in the summer period of the year it was 50% less than the physiological norm, the level of pyridoxine in the diet was 0,87-1,14 times less. The content of pantothenic acid in the diet was 66,6-72,0%. The daily content of cyanocobalamin was lower by 30-40% of the norm. The daily intake of niacin in different seasons ranged from 3,3 to 3,57 times lower than the standard values. Also, the content of ascorbic and folic acid in the daily diet was below normal. Thus, it is necessary to adjust the composition of the daily diet of schoolchildren in accordance with physiological norms.
