[Effect of long time storage of infant formulas on their vitamins A, E, levels of peroxide value and antioxidant activity as compared to breast milk].

It is shown that vitamins A and E content in infant and follow-on formulae was significantly higher comparatively to declared level while their content decreased during storage at room temperature in open boxes in accordance with manufactures recommendations. Vitamins A and E level decrease accompanied by formulae anti- and prooxidants ratio changes and peroxide value increase in all formula studied. The minimal level of vitamin A and E increase above declared one during manufacturing of infant formula that allows to maintain the actual vitamins level in accordance with declared one was grounded. Breast milk antioxidant activity was different from that one of started and follow-on formulae. The data obtained shows the necessity to optimize the antioxidant composition of infant and follow-on formulae to make their content and functional activity closer to human milk.
