Malnutrition has become an urgent global health issue, with under nutrition killing or disabling millions of children each year. In India about 2/3 portion of the under five children of our country is malnourished among them 5-8% is severely malnourished whole rest fall in the group of mild or moderate malnutrition so it can be said that malnutrition one of the widest spread conditions affecting child health. The aim of present work was to investigate the antioxidant profile of composite flours of Finger Millet, Black soybean and Moringa Leaf Powder for different composition. The composite flour was prepared using Finger Millet, Black soybean, Moringa Leaf Powder and Durum Wheat Flour; Control (100% Durum Wheat Flour) respectively. The antioxidant evaluation DPPH Radical Scavenging Activity, FRAP Radical Scavenging Activity; Total Phenols Content and Total Flavonoids Content of composite flours were analyzed with standard procedure. The result revealed that among all the composite flour CF-3 had significantly highest antioxidant content when compared with Control, CF-1 and CF-2 and registered significant difference at p<0.05 level. The addition of Finger Millet, Black soybean and Moringa Leaf Powder in composite flours has been shown in this study to improve the nutrition, antioxidant content and health benefits of the body which could be further used for alleviating child malnutrition.
