Introduction: Complementary feeding is the gradual withdrawal of breast milk and introduction of other foods like semi-solid or solid foods to a baby; these new foods become a source of energy and nutrient intake. Objectives: The specific objectives were to: (i) determine the proximate composition of orange fleshed sweet potatoes and soybean blends; (ii) determine the mineral composition of orange fleshed sweet potato and soybeans blends; (iii) determine the vitamin composition of the orange fleshed sweet potatoes and soybean blends; (iv) determine the sensory attributes of the orange fleshed sweet potatoes and soybean blends. Materials and Methods: The Orange fleshed sweet potatoes and Soybeans (glycine max) were collected from National Root Crops Research Institute (NRCRI), Umudike, Nigeria and a market in Nasarawa State, Nigeria respectively. Padmaja. (2009) method was used in the production of Orange fleshed sweet potatoes flour. The complementary foods were formulated using a combination of orange fleshed sweet potatoes and soybeans in the proportion of 50%:50%; 60%:40%; 70%:30%; 80%:20%; 90%:10% respectively. Commercial complementary food (corn gruel) was used as a control. The porridge was prepared with a 100g of the complementary flour added to 100ml of hot water (60°C). The sample was kept separately in thermos flasks to maintain the serving temperature of -28°C as it was served to nursing mothers. The proximate, minerals, vitamins compositions of orange fleshed sweet potatoes and soybean blends were determine using standardized methods. Results: Result obtained show that OFSP and SBB had moisture content 8.10g, protein 19.82g, fiber 4.70g, lipid 8.71g, ash 2.43g, carbohydrate 66.2g and energy 390kcal. There was significant difference p< 0.05 in the proximate analysis. OFSP and SBB had vitamin A content of 4743.5µg and vitamin C content of 12.36mg/100g. There was no significant difference p>0.05 in vitamins analysis. The mineral composition of OFSP and SBB had Iron 3mg/g, Calcium 18mg/g and Zinc 2mg/g. There was no significant difference p>0.05 in the mineral analysis. Conclusion: Adequate complementary food can meet the nutritional needs of infants.
