The objective of this study was to investigate the quality characteristics of Baeksulgi (BS) and Sulgidduk added with Makgeolli (MS, BS+ Makgeolli) during storage at 20±2 for 3 days. Moisture contents of MS were significantly higher than those of BS during storage. Reducing sugar contents (%) were higher in MS. The pH values were 6.23 and 5.93, for BS and MS, respectively. The pH of MS was lower and thus indicated higher in acidity. The Hunter color L (lightness) and a (redness) values were higher for BS, whereas b (yellowness) value of MS was lower. In the texture analysis, hardness and chewiness of MS were found to be lower, whereas springiness, gumminess, and resilience were higher than those of MS. According to DSC (Differential scanning calorimeter) analysis, enthalpy of MS appeared to be lower than that of BS during storage, which suggests retrogradation of MS was delayed. The total phenol content was higher in MS. The IC50 value of DPPH and hydroxyl radical scavenging activity was lower in MS, which means antioxidant activity increased in MS. Results of the preference test showed that appearance, flavor, taste, and overall acceptability of MS scored higher than those of BS. From these results, high quality of MS was derived from Makgeolli addition.
