Abstract

The aim of this study was to evaluate the appropriate technological treatments and the couple time / temperature optimizing the availability of nutrients in cowpea grains. White cowpea grains used were bought at Abobo (Abidjan) market. After germination and fermentation, these grains were heated to boiling for 1 hour (h) and 1h30 min at coal and gas fires and then crushed. The biochemical and nutritional profile was performed on the flour obtained. The results showed a significant difference on the parameters studied according to the treatment applied. The dry matter content of the flours was higher than 90%. The protein content was high on the flours from sprouted grains after cooking for 1 h on charcoal (Gfc2) and gas (Gfg2) fire with respective values of 18.31 ± 0.05% and 19, 83 ± 0.50%. On the other hand, the lipid content was less than 3%. The total carbohydrate content in all the flours is between 68 and 80 %. Fibers content varies between 23 and 31 %. Whatever the cooking method used, results showed that the mineral contents were higher after 1 hour cooking. The nutrient profile by the determination of scores SAIN > 5 and LIM <7.5 classified the cowpea in food of group 1, recommended foods for health. The flours from germinated and fermented Cowpea with a high energy value could be recommended as a local product in the formulation in infant food.
