Abstract

|
|
This study investigated the quality characteristics and antioxidant activity of Yanggaeng prepared with various amounts of watermelon radish flesh (WRF) powder, in ratios of 0 (control), 2.5, 5, 7.5, and 10% of the cooked white bean paste. The proximate composition, pH, sugar content, Hunter’s color values, texture analysis, and antioxidative activities of Yanggaeng were examined.
Increasing the amount of WRF in the Yanggaeng tended to increase the crude ash, carbohydrate, sugar, total polyphenol, total flavonoids, and anthocyanin contents, a value, DPPH and ABTS radical scavenging activities, with decreasing the moisture and crude protein contents, L and b values, and pH. Texture measurement scores in terms of springiness, chewiness for Yanggaeng showed that 2.5% or 5.0% group was higher than those of the control group. Hardness was higher in the sample groups than in the control group. In conclusion, the results show that Yanggaeng with up to 7.0% added WRF powder can be developed as products, and there is a possibility of developing health functional snack products using WRF powder.
