Abstract
Effect of protease and 2-mercaptoethanol treatment on the texture of cooked rice was investigated. Hardness, chewiness and gumminess of cooked rice were decreased by reducing the disulfide bonds of protein using 2-mercaptoethanol. Protease-treated rice grains, when cooked, showed more favorable results in stickiness measured by Instron, hardness measured by rheometer and sensory acceptability of cooked rice. Water content and volume expansion of cooked rice were increased by protease or 2-mercaptoethanol treatment. This results suggested that the textural characteristics of cooked rice may be influenced by surrounding or closely associated protein.
쌀 단백질이 밥의 식미와 텍스쳐에 미치는 영향을 밝히기 위하여 단백질 가수분해 효소와 이황화결합 환원제 처리가 밥의 텍스쳐에 미치는 효과에 대하여 시험하였다. 세 품종의 찰밥의 경도, 부착성, 탄력성 등은 유의한 차이가 있었다. 그 중 IR 36의 밥이 가장 단단하고 부착성이 적었다. 밥의 경도는
