Legumes represent an important protein source worldwide. In Venezuela, they are generally prepared at home and are consumed by adults, as soup or stew, while children eat them in very small quantities. In order to include legumes in the children’s diet, the following work was done using cowpea (Vigna sinensis) as an complement of chicken in the preparation of a nutritionally balanced formula, adapted to the requirements of children. Several formulas were developed and three of them were selected based on their acceptability. In the first formula, the protein source was only of chicken. In the second formula, the chicken was partially substituted by cowpea, and in the third formula, the protein source was only made of cowpea. Other formula ingredients included rice, pumpkin (Curcubita maxima), carrot and some seasonings. Proximal analysis, protein quality (as protein efficiency ratio and protein digestibility) and sensory evaluation (7-point hedonic scale) were performed on the formulas. The proximal composition was similar in the three formulas: protein (3.5%), fat (1.3%) and carbohydrates (19.7%), with a good distribution of the energy contribution (98,9 kcal/100g or 413,8 kJ/100g). The protein quality and protein digestibility were higher for the chicken-cowpea formula than for the cowpea one. The acceptability with the mothers was higher for the chicken-cowpea formula than for the cowpea one. The acceptability of the chicken-cowpea formula with children was 77% (7-point hedonic facial scale) and 92% (measuring consumption). Due to the high acceptability and good protein quality, the chicken-cowpea formula could be included in the lunch meal of the children in daycare homes.
