The objectives of this study were to investigate the quality of ginseng makgeolli during the fermentation and aging period, and to develop Jeungpyun manufactured by ginseng makgeolli. Four different amounts of ginseng powder (0, 2, 4 and 6 g) were added to the filtered mash which was fermented for 4 days at 24 °C and then aged for 6 days at 4°C The quality of Jeungpyun batter containing 0, 2, 4 and 6% ginseng during fermentation, and the sensory, color and textural characteristics of ginseng Jeungpyun were analyzed. The pH of jeungpyun batter without ginseng was lower than the other batters. During 4 hours of fermentation of the batter at 30°C, the pH of the batter significantly decreased. The expansion volume of the batter without ginseng increased 4.11 times after 4 hours of fermentation, whereas batters with 2, 4, and 6% ginseng increased 1.70 times. The L value of Jeungpyun decreased by increasing the concentration of ginseng However the a and b values of Jeungpyun significantly increased with an increase in the concentration of ginseng. The results of the sensory evaluation showed that Jeungpyun with 2% ginseng had the highest flavor, taste and overall acceptability scores. In the textural analysis, the hardness of Jeungpyun increased by increasing the concen?tration of ginseng after 6 days of storage at 20 °C. This study showed that Jeunpyun containing 2% ginseng was the optimum addition level.
