Abstract

The investigation aimed at determining the retention and bioaccessibility of b-carotene on baking. Bun was formulated incorporating dehydrated carrot/ drumstick leaves/synthetic form of b-carotene at acceptable levels. The effect of citric acid and turmeric powder on the bioaccessibility of b-carotene was examined. Buns were analyzed for proximate composition, total and bioaccessible b-carotene. Incorporation of different sources of b-carotene did not alter the physical characteristics and proximate composition of the buns. Retention of b-carotene on baking ranged between 62 and 72% in buns with natural sources and 35% in buns with synthetic source. b-carotene in the buns showed a high degree of stability on storage. Bioaccessibility of b-carotene in bun was 5.8% with carrot, 7.1% with synthetic source and below 1% with drumstick leaves. Addition of enhancing components increased the bioaccessibility to a remarkable extent. The study results suggest the possibility of fortifying buns with b-carotene with enhanced bioaccessibility. PRACTICAL APPLICATIONS The study identified natural and synthetic forms of b-carotene to be incorporated in bun. Bun is the ideal product for fortification; it is easily acceptable by children in whom vitamin A deficiency is highly prevalent. Carrot and drumstick leaves are rich and economical sources of b-carotene. The selected vegetable sources contain other micronutrients in addition to b-carotene that will improve the nutritive value of buns. Hence, incorporation of carrot and drumstick leaves in buns will have good market potential. The selected sources of b-carotene are fromeasily available natural sources which are economically feasible. The product formulation is well standardized for organoleptic parameters for large-scale production.
