Abstract
With the steady growth in the scale of the domestic traditional liquor industry, the interest in makgeolli has also been increasing. As the demand for makgeolli increases, interest in manufacturing differentiated makgeolli by adding additional raw materials such as fruits is increasing. In this study, makgeolli with low storage persimmon juice was manufactured, and the sweet taste of persimmon was imparted without adding sweeteners. Unsweetened, high-quality persimmon makgeolli with an alcohol content of 15% or more was manufactured and its quality characteristics were analyzed. Yeast was selected after producing fermented yeast by treating domestic isolated yeast and commercial yeast. Upon producing fermented yeast, persimmon makgeolli was manufactured by varying the amount of persimmon juice added to the fermented yeast. As a result of analyzing the quality characteristics of persimmon makgeolli, the pH was 4.02-4.25, the total acid (citric acid, %) was 0.30-0.43, the amino acidity (glycine, %) range was 0.05-0.15, and the alcohol content (%) was 15.64-18.48.(p<0.05). Reducing sugar (%) was 1.82-12.68 and total sugar (%) was 1.41-10.42, exhibiting a tendency to increase as the amount of reducing sugar and total sugar and the amount of juice added increased (p<0.05). Considering the sensory characteristics, a sample with 50% persimmon juice added showed a significantly higher residual sugar content, and the residual sugar content had a positive effect on the sensory characteristics. Therefore, 50% persimmon juice was added when making persimmon makgeolli. It is suitable for high-quality, non-sweetened persimmon makgeolli that preserves the taste of persimmon, which suits the consumers'taste.
