Abstract
Modern food products do not contain a high content of nutrients, in particular minerals. The consumption of such products affects not only the health of the nation but also the economy of the country. According to the World Health Organization, the lack of the mineral element iron remains relevant, especially among children and pregnant women not only in developed countries, but all over the world. This article presents studies of the effect of cow's milk enrichment on the physico-chemical and organoleptic qualities of fortified milk. The cow's milk with a fat content of 3.6 and 2.8% was enriched with iron sulfate (FeSO4.7H2O) and trivalent ammonium citrate (C6H8FeNO7). The samples of Ferrous Sulfate (10mg) and Ferric Ammonium Citrate (10mg) showed significant changes in milk with fat content 2.8 % fortification. The effect of iron enrichment on the process of milk fermentation was also studied, and a milk sample was taken. The milk sample fortified with iron had a considerable acidity increase on 3 h from 22°T to 800T, this is by 37 % compared to the control sample. The effect of iron enrichment on the fermentation process or the supporting role of iron in the growth of fermenting bacteria is still in question, although a number of studies have been conducted in this area, but more clarity and specific research and experiments on this issue are still needed.
