청도반시를 이용하여 감와인 및 증류주 개발을 위해 감과실의 알코올 발효특성을 조사하였다. 알코올 발효에 적합한 균주를 선별한 결과 S. kluyveri DJ97이 알코올 함량 10.8%, 알코올 수율 96.3%로 높게 나타났으며, 메탄을 함량은 935 ppm으로 가장 낮게 나타났다. 초기 와 가수량의 영향을 조사한 결과 초기 , 가수 120%(v/w)군간에서 알코올함량 10.7%로 가장 높게 나타났으며 pectinase 무처리군에서 알코올 함량이

Alcohol fermentation conditions were investigated using 'Cheondobansi' astringent persimmon (Diospyros kaki T.) for the study of persimmon wine and distilled liquor, The optimal yeast strain for 'Cheongdobansi' astringent persimmon alcohol fermentation was Saccharomyces kluyveri DJ97, which showed 10.8% of alcohol concentration, 96.25% of alcohol yield, and 935 ppm of methanol. The initial conditions of and 120%(v/w) water addition resulted in the highest alcohol concentration of 10.7%. The alcohol concentration was higher in pectinase non-treated samples than in pectinase-teated samples. Lower concentrations of acetaldehyde and n-propanol were measured for the pectinase-treated sample than for the non-treatment samples. However, the methanol concentration of the pectinase-teated sample was higher than that of the pectinase non-treatment sample.
