Abstract: Red kidney bean protein isolate was prepared and incorporated into wheat flour at levels of 0, 5, 10, 15, and 20% to prepare protein-enriched cookies which were then evaluated for various quality attributes. Nutritional evaluation of cookies showed that the supplementation of bean protein isolate increased the protein content of the cookies from 7.87% in T1 (control or wheat flour cookies) to 16.92% in T6 (cookies supplemented with 20% bean protein isolate), which indicated a 115% increase in protein content. The physical characteristics of cookies such as width, thickness and spread factors differed significantly. Sensory attributes of all the supplemented cookies were within the acceptable range but cookies supplemented with 20% level of protein isolate were less preferred due to slightly darker colour and harder texture. Conclusively, the red kidney bean protein isolate can be successfully utilised for the production of high-protein cookies. Such high-protein products can be advantageously utilised to cope with the problem of protein-energy malnutrition. Moreover, such nutritious products can also be used as emergency foods during natural disasters as well as during war times.
