Abstract
This study investigated the effect of different cereal-legume blending ratios on nutritional quality and functional property of different blends. The legumes and steeped cereals were cleaned, minimally roasted, dehulled, milled and sifted separately. A single-factor experiment with three levels of the factor (cereal: legume ratio 85:15, 75:25 and 65:35 coded as B1, B2 and B3, respectively) with two replications were used to conduct the experiment. The collected data were subjected to analysis of variance using SPSS statistical software and compared with the recommended values for the age group of 6-24 months. Mean separation result showed that protein, fat, energy, crude fibre and ash contents were significantly (p<0.05) different among the blends where B3 revealed higher values. Protein contents of B2 and B3, ash and fiber content of the three blends, as well as energy value of B3 were within the recommended levels. However, none of the blends met the recommended fat content. Calcium, zinc and iron content of the blends increase as the proportion of legumes increase, but only the iron value was within the recommended level. The molar ratio of phytate and the three minerals were within the recommended value for better absorption. Water solubility index increased as the proportion of legume increased from 15% to 25% then decreased as legume increased to 35%. B1 revealed significantly higher viscosity values (248.43±3.35cP) and viscosity decrease as the proportion of legume increased. Based on 10 nutritional and functional criteria, B3 possess the most desirable among the studied blends.Key words: Cereal-legume blend, proximate composition, anti-nutrient, phytate/mineral molar ratio

Summary
Malnutrition is a disparity between the amount of food and other nutrients that the body needs and the amount that it is receiving. In the developing world two-third of child mortality and morbidity is attributable to malnutrition. Important period of tackling malnutrition is the period of complementary feeding when foods of low nutrient density begin to replace breast milk and rates of diarrheal illness caused by food contamination are at their highest (Brown et al, 1998; World Bank, 2005). Children aged 6-24 months are at the highest risk of malnutrition mainly due to sub-optimal complementary feeding practice. As a result, they fail to attain their full potential of growth and development, suffer long-term deprivation of energy, nutrients, and chronic protein energy malnutrition (PEM), often accompanied by micronutrient deficiencies. The period 6–24 months of age is one of the (http://creativecommons.org/licenses/CC BY4.0)
