초록

Aronia makgeolli was manufactured using Asp. kawachi (AK) and Asp. awamori (AA) with tannase activity, and physicochemical properties were examined during the fermentation period. The pH was decreased during the fermentation period after the first day, while the acidity increased. Reducing sugars increased highly on the first day of fermentation, and then they gradually decreased as the fermentation period elapsed. On the 7th day of fermentation, it was in the range of 0.38~0.61%. The alcohol content gradually increased during the fermentation period and it ranged from 13.4~14.2 v/v% by the 7th day of fermentation, and the alcohol content of makgeolli added with Aronia was somewhat lower than that of makgeolli prepared without aronia. The L value increased as the fermentation period elapsed, and the L value of makgeolli added with aronia increased rapidly. The a value gradually decreased, while the b value gradually increased as the fermentation period elapsed. The content of total polyphenols increased during the fermentation period of AK makgeolli. However, the AA makgeolli was not significantly increased, as compared to the initial stage of fermentation, and it was lower than that of the AK makgeolli. The radical scavenging activity of the DPPH was higher in the makgeolli added with aronia, and the antioxidant activity of AA makgeolli was higher than that of AK makgeolli. In the sensory evaluation, in the AK makgeolli, the palatability deteriorated due to the bitter taste and the astringent taste derived from the aronia. However, in the AA makgeolli, astringent taste was very weak and the sensory quality was good.
