| Research Abstract |
Black purple rice is rich in anthocyanin pigments with various functions. Therefore, black purple rice would be able to utilize as functional food. However, changes in functionality by cooking and processing of black purple rice is unknown. In this study, breads containing black purple rice flour were prepared, the changes in antioxidant properties and behavior of anthocyanins in the processing were examined. While 80% of cyanidin 3-glucoside (C3G), a major anthocyanin in black purple rice, was degraded to protocatechuic acid (PCA), PCA showed antioxidant higher than C3G.These results show that black purple rice after processing has antioxidant property.
