Abstract: This research was aimed to study the physicochemical properties and antioxidant activity of biscuits fortified with red kidney bean (Phaseolus vulgaris) powder. Proximate compositions, total phenol content, antioxidant activity, and functional properties of red kidney bean (RKB) powder were studied before and after the incorporation of red kidney bean in the biscuits. The bean powder was mixed with wheat flour at a level of 0 as control, 10 , 20 , and 30 during dough preparation. Results revealed that RKB powder is a rich source of protein (26.25 ) together with carbohydrate (59.7 ), fat (2.4 ), and ash (3.27 ). The total phenolic content of bean powder was 14.15 mg GAE g. Kidney bean powder showed good functional properties including water absorption capacity (149.7 ), oil holding capacity (99.54 ), swelling capacity (4.6 ), and bulk density of 0.74 g ml. After increasing the percentage of RKB with control, there were significant increases (p
