Abstract

ABSTRACT Black rice, known for its high anthocyanin and antioxidant content, is native to Asian countries like Japan, China, Thailand, India, and Indonesia. In India, it is primarily grown in Manipur, Assam, and Meghalaya, where it is called Chakhao. Despite its health benefits, black rice remains underutilized in food processing. This study examined the rheological behavior of Chakhao black rice flour blended with wheat flour (BR1, BR2, BR3) using alveograph and mixograph tests. BR3 showed the best baking properties, with a G value of 17.5 and p value of 90 mm H₂O, indicating its suitability for baking, especially cookies. Nutritionally, BR3 cookies were rich in protein (10.4%), fiber (2.91%), and minerals (2.95%). High starch retrogradation limits use in bread and biscuits. BR3 cookies are sensory-acceptable and can be marketed as healthy, functional products. Future research could focus on improving taste while maintaining health benefits.
