Four complementary samples were produced from the proportion of maize/soyabean/banana composite flours as 60%： 30%： 10% （B）, 60%： 25%： 15% （C）, 60%： 20%： 20% （D）, 50%： 30%： 20% （E） and Nestle Cerelac was the control sample （A）. The formulated diets were subjected to nutritional analysis-along with a commonly used proprietary infant cereal （Nestle Cerelac） as control. Standard chemical methods were used to determine the proximate nutrient composition, some micronutrients and anti-nutritional factors. The samples produced have increased nutrients of fibre that enhances digestibility （2.07%-3.11%）, protein and ash contents. The supplementation of up to 20% soybean flour and banana flour recorded the best results in terms of proximate and mineral compositions and compared favourably with the control sample, in terms of sensory evaluation using hedonic method, sample A was most accepted but did not differ significantly from sample D. Therefore, nutritious and acceptable complementary food can be produced from fermented maize, soybean and banana flours. Results of molar ratios of some minerals and anti-nutritional factors in the compounded diets suggest that the anti-nutrients will not pose any serious problem in the usage of the complementary diets. The cost of producing the formulated diets is about N50-N100 （50 cents） per gram cheaper than cerelac. The study has therefore, revealed that with proper selection of local foodstuff, it is possible to prepare nutritious complementary diets that would be acceptable, readily available, affordable and nutritionally adequate.展开更多
