|
The purpose of this study was to investigate the quality characteristics of Garaedduk with regard to the amount of added whole soybean curd (Chun-Tofu). Whole soybean curd was added in amounts of 0, 3, 6 and 9%. Whole soybean curd Topokki dduk was stored at room temperature for 48 hours. The moisture contents had no significant difference for increases in the amount of whole soybean curd. The L value and b values of Garaedduk increased significantly with increases in the amount of whole soybean curd. Texture characteristics of Garaedduk measured with a texture analyzer revealed that hardness and cohesiveness decreased significantly for different amounts of whole soybean curd, and hardness increased significantly and cohesiveness and chewiness decreased with increase of storage time. As for sensory characteristics, samples with 9% added whole soybean curd rated higher in overall acceptability compared with other samples. In regard to cooking properties, water absorption increased and solid contents decreased with increases in the amount of whole soybean curd. Therefore, Garaedduk containing 9% whole soybean curd was most preferable.
