Abstract

The physicochemical characteristics and sensory properties of Jinyangju were investigated at different degrees of milling (DOM; 0, 5, 7, and 10%) of waxy glutinous rice after 2 weeks of fermentation. The final pH values were 3.50, 3.84, 4.16, and 4.21 at the DOMs of 0, 5, 7, and 10%, respectively. The final total acidities were 1.21, 1.16, 0.94, and 0.91%; final total sugar contents were 6.38, 6.51, 5.54 and 5.40%; and final alcohol contents were 14.50, 14.50, 15.50, and 15.40%, respectively. Hunter L-value of the DOM 5% rice was lower those of the DOM 7% and 10% rice, but its Hunter b-value was higher than those of the DOM 7% and 10% rice. However, Hunter a-value of the Jinyangju were not significantly different among the samples (p>0.05) Hunter L-value. The Jinyangju made with the DOM 7% rice showed the highest overall sensory preference.

찹쌀의 도정도가 진양주에 미치는 영향을 조사하기 위해 도정도를 달리하여 진양주를 제조하여 그의 이화학적 특성과 품질 특성을 조사하여 진양주 제조에 적합한 도정도를 찾고자 하였다. 14일간 발효 후 최종 pH는 10분도미를 원료로 제조한 진양주가 4.21, 7분도미가 4.16, 5분도미가 3.84, 찹쌀 현미가 3.43으로 나타내었고 총산은 찹쌀 현미, 5, 7, 10분도미가 원료로 제조한 진양주가 각각 2.03, 1.83, 1.75, 1.76%로 나타내었다. 총당의 함량은 찹쌀 현미와 분도미를 원료로 한 진양주가 6.38%와 6.38로 나타내었고 7과 10분도미로 제조된 진양주가 5.54%와 5.40%로 나타내었다. 에탄올 함량은 7과 10분도미를 원료로 한 진양주가 15.5%와 15.4%로 찹쌀 현미와 5분도미를 원료로 한 진양주 14.5%와 14.4%보다 높게 나타내었다. 색도 중 L값은 도정도가 높을수록 더 높게 나타났으나 낮게 나타내었다. 전체적 기호도는 7과 10분도미를 원료로 진양주가 각각 5.45와 5.35로 찹쌀 현미와 5분 도미를 원료로 한 진양주보다 높게 나타내었다. 이화학적 특성, 품질 특성, 원료에 대한 수율을 고려해 볼 때 진양주는 7분도미로 제조하는 것이 바람직하다고 생각되었다.
