Abstract ▼ AI-Helper

This study investigated the antioxidant activity and general and sensory properties of soybean curd supplemented with Codium fragile. The yield of soybean curd containing 0%, 20%, and 40% C. fragile was 113.62, 104.09, and 108.06, respectively. Antioxidant activities and pH were significantly increased (P<0.05) depending on the amount of C. fragile supplemented in soybean curd. Compared to that in additive-free soybean curd (control), the amount of crude ash and protein in soybean curd containing 40% C. fragile was significantly decreased (P<0.05) and increased (P<0.05), respectively. We observed a dose-dependent increase (P0.05) in soybean curd's cohesiveness between the groups. As determined by sensory evaluation based on seven-point hedonic scale, soybean curd supplemented with 20% C. fragile received an excellent score (6.55) for color. As the same method, we observed that the flavor and overall acceptability significantly increased (P<0.05) in the C. fragile content increased. Taken together, the antioxidant and sensory assays in our study make a compelling case for the practical development of soybean curd supplemented with C. fragile owing to its good antioxidant activities, general properties, and consumer acceptance.
