Abstract
The efforts were made to develop persimmon leaf beverages on the basis of the results of sensory evaluation. The result of sensory evaluation for the development of persimmon leaf beverages showed that when the concentration of extracts was 10%, the aroma and flavor of persimmon leaves was best. The optimum concentration of sugar was 4.5% and apple juice was 15%. The change of pH had the tendency to keep stable range(3.82-3.71) during the period of 30 days and free-sugar had little change according to the temperature and time of preservation. The preservation of the change of ascorbic acid revealed that the range of decrease in the case of preservation at
최적 추출조건에 의한 감잎 음료 개발에 관한 관능검사 실험에서는 추출물의 농도 10%가 감잎의 향과 맛의 정도가 가장 적당한 것으로 나타났으며, 당의 농도는 4.5%로 나타났다. 그리고 적정향료와 과즙첨가 시험에서는 사과향이 감잎과 가장 잘 어울리는 것으로 나타났고 사과과즙 첨가량은 15%가 가장 적당한 것으로 나타났다. 관능검사 결과를 바탕으로 감잎 음료를 개발하여
