The germination of legumes has changed the physicochemical properties and biological substances. The study germinated of cowpea and dolichos after 4 days. Germination promoted a significant decrease of resistant starch along with an increase of available starch percentage. Total dietary fiber contents increased during germination and improved insoluble/soluble dietary fiber ratio. Moreover, physicochemical properties of germinated legume flours were modified, improving oil holding, water holding, water absorption and gelation capacities. In addition, study of antioxidant activity in Mung bean and Soybean were germinated at 30°C for 5 days. Antioxidant activity varied 32-35% after germination.
