ANY PARTICULAR TIME AND TEMPERATURE RANGES IN BREASTFEEDING IN VITAMIN A, E AND Β-CAROTENE LEVELS DETERMINATION

Human milk is widely accepted as optimal for human infants nutrition. Human milk, which contains compound benefical to infants is often expressed and stored before use. Changes in its antioxidant activity with storage have not been studied.Breastfeeding and human milk are widely accepted as optimal for human infants nutrition. Nowadays lifestyle often makes it difficult to maintain or even initiate human lactation. This stuation is mostly related to the workload of women away from home. Human breast milk storage for differed use is on possibility. At the determined time period vitamin A, E and β-carotene values show differences at +4 °C and -20°C at the same time for each group. Seen that vitamin A, E and β-carotene contents of milk examples hold at –20 °C is more preservative than the milk hold at +4 °C. β-carotene values determined at +4 °C for I, II and III groups accordingly 8.61, 5.92 and 4.32 µg/dl but for IV, V and VI groups at -20 °C this values found accordingly 8.21, 7.42 and 5.33 µg/dl. b-carotene values of control group is 9.65 µg/dl but our investigations show that this amount has been more preserved in V and VI groups than II and III groups. Also vitamin E value at the same groups and at the +4 °C accordingly are, 51.34, 46.65 and 42.85 µg/dl, at the –20 °C accordingly 50.88, 47.64 and 44.73 µg/dl. Vitamin E values again at the same groups accordingly at the +4 °C 26.12, 22.56 and 1 accordingly 8.20 µg/dl and at the –20 °C 25.98, 23.34 and 20.37 µg/dl. Storage of human milk is safe at 4 oC for 4 hours, whereas at -20 oC it is saf e for 7 days.
