Selection and justifi cation of the formulation and vitamins of a fruit and nut bar for schoolchildren

Long-term consumption of school meals contributes to the formation of a defi ciency of a number of biologically active substances and necessitates the need to enrich products for school diets with vitamins and minerals. Existing commercial forms of vitamins are considered. Despite their diversity, the use of each form of vitamins has a number of restrictions. An option to increase vitamin intake among schoolchildren could be the development and introduction of fortifi ed products into the menu. Based on the study of the role of vitamins in the human body and the comparison of the vitamin and mineral composition of nuts, vitamins for fortifi cation were selected in the amount of daily intake for children per bar (at the lower limit, %): vitamin C in the amount of 90 mg and vitamin A in the amount of 400 mcg (ret eq) per bar. Based on the conducted research, the choice of the main ingredients and vitamins C and A for fortification, as well as the calorie content of the fruit and nut bar were justified.
