• Infants Commercial complementary foods
• Retinyl acetate, retinyl palmitate, beta-carotene
• alpha-Tocopherol, gamma-tocopherol
• Vitamin E, vitamin A and carotenoids
• HPLC
• Toxicity

According to the European Food Safety Authority, currently, there are no reliable data or robust guidelines available in relation to the micronutrient composition of infant foods. This study evaluated the intake of vitamins A and E of infants from 'ready-to-feed' foods and formulas. Normal phase high performance liquid chromatography was employed for simultaneous quantification of retinyl acetate, retinyl palmitate, alpha-tocopherol and gamma-tocopherol, reverse phase high performance liquid chromatography for the quantification of beta-carotene, and UV spectrophotometry for the quantification of carotenoids from selected infant food samples. Based on the results of this study, the estimated total daily intake of vitamin A (retinol equivalents) and vitamin E (alpha-tocopherol equivalents) from both infant food and formula milk exceed recommendations set by the UK Department of Health. This requires further analysis of risk of exposure, whilst a cause for concern over deficiency might arise when the intake of milk is compromised.
