Abstract

Breastfeed is the ideal food for newborns. One of the substances in breastfeed that serves to help the growth, development, and body defense of the baby is ascorbic acid. Ascorbic acid of breast feed is unstable and will easily oxidized by the temperature and quantity levels of loss propagated by storage time. Breastfeeding mothers who work outside of home can not immediately give her breastfeed, therefore breast feed squeezed manually collected in bottles that has been sterilized, then stored on the room and refrigerator. The aim of this research was analyzed the difference of ascorbic acid levels of breastfeed based on variations of temperature and time storage. This research was a quasi experimental with factorial design. The research consisting of 4 experimental groups, they are T1W1 (4 viii

o C storage for 5 hours), T2W1 (26 o -28 o C storage for 5 hours), T1W2 (4 o C storage for 9 hours) and T2W2 (26 o -28 o C storage for 9 hours). On the otherhand there is a control group (without storage) as a comparison. The design drawn up in factorial study consisted of 8 repetitions (replication). By using the One way ANOVA test, it is known that there were significant differences in ascorbic acid content of breast feed between the control group and the experimental group, with P value = 0,002. The most decreased levels of ascorbic acid on storage at room temperature (26 o -28 o C) for 9 hours. Therefore, to keep the optimum levels of ascorbic acid preferably breastfeed is not stored on the room for 9 hours or more.
