Abstract

Infants and young children are most affected by household food, thus there is a need for complementary foods that are safe and inexpensive. The study was set out for the purpose of developing an instant complementary food from sweet potato and corn. Corn (IPB variety 6) and four cultivars of sweet potato namely, cream-fleshed (CFSP), yellow-fleshed (YFSP), orange fleshed (OFSP) and purple-fleshed (PFSP) were mixed in eight different proportions. Blends with highest dispersibility, 55:45 (sweet potato-corn), were analyzed for nutritional value and functional components and subjected to sensory evaluation. The nutrient content per 100 g of sample range from, 3.13-2.81g protein; 1.7-1.6 g fat; 361-367 kcal total energy; 28.6-765.5 μg ẞ-cartene; 1.5-3.7 mg iron; 0.5-1.3 mg zinc; while functional components ranged from, 216.5-283.3 mg catechin equivalents for total phenols; 12.2-28.0 mg gallic acid equivalents for flavonoid; 0.1-0.2 mg catechin equivalents for tannins; 11.5-22.6 mg catechin equivalents for anthocyanin; and 43.3-59.4% antioxidant activity. Generally, lends were acceptable in terms of aroma, mouth feel and taste. Purple-fleshed sweet potato-corn was superior in terms of nutrient composition and functional components. The results showed that the blends are potential complementary foods for improvement of nutritional status of children.
