Vitamin A Activity of Rice-based Weaning Foods Enriched with Germinated Cowpea Flour, Banana, Pumpkin and Milk Powder.
The objective of this study was to identify the effect of different drying methods on vitamin A activity of formulated weaning food. Weaned foods on vitamin A activity of formulated using treated cowpea flour, locally available rice flour, banana-pumpkin, skim milk powder and sugar in the ratio 35:35:15:15:5. Treated cowpea flour consisted of original cowpea flour, 24 h germinated cowpea flour. Each treated flour was mixed separately with the other ingredients and cooked into a slurry. Each mixture was either oven-dried or freeze-dried to produce a dry flaky mixture. The carotenoid composition of the product was determined by HPLC. Vitamin A activity of oven-dried weaning food was significantly reduced (p<0.05) compared to freeze-dried weaning food. The freeze-dried weaning foods showed a higher retinol equivalent than oven-dried weaning foods for all treatments. The results of the study found that an intake of 100 g of freeze-dried weaning foods enriched with banana-pumpkin and cowpea flour provided an adequate amount of the recommended daily allowance (RDA) of vitamin A for infants.
