Abstract

Fermentation characteristics for the production of honey wine with Saccharomyces sake, Saccharomyces bayanus and nuruk were investigated. Among the yeast strains and the mixture with nuruk tested, nuruk-Sacch. sake mixture and nuruk-Sacch. bayanus mixture showed higher alcohol production and better fermentability than the single strains. Total acid and pH did not change considerably during the whole period of fermentation. As the fermentation progressed, reducing sugar decreased rapidly until the 6 days of fermentation, while alcohol content increased rapidly during the same period. In fermentation of 6 days, honey wine consisted of about $7.5{\sim}8.1^{\circ}Brix$ of soluble solid, $22.7{\sim}31.8%$ of reducing sugar. Alcohol content were reached up to 12.5 and 13.1% for honey wine manufactured with nuruk-Sacch. sake mixture and nuruk-Sacch. bayanus mixture, respectively, relative to $5.2{\sim}7.2%$ of the single strains. Generally, honey wines prepared with the mixture of nuruk-yeast strains were fermented more efficiently than those with the single yeast.

벌꿀주를 Sacch. sake, Sacch. bayanus, 그리고 누룩을 이용하여 발효시킨 후 그 특성을 조사하였다. 벌꿀희석액의 알코올발효에는 Sacch. sake와 누룩 혼합첨가구 그리고 누룩과 Sacch. bayanus 혼합첨가구에서 효모 단독균주를 이용하는 것보다 발효력이 우수하였고 알코올 생성량도 높았다. 벌꿀주의 pH와 산도는 발효과정 동안의 변화가 적었다. 누룩과 효모 혼합첨가구의 경우 발효중 환원당은 급속히 감소하고 알코올 함량은 증가하여 발효 6일에 가용성 고형분은 $7.5{\sim}8.1^{\circ}Brix$, 잔류 환원당은 $22.7{\sim}31.8%$이었다. 발효 6일에 알코올 생성은 누룩과 효모 혼합첨가구를 사용한 경우가 $12.5{\sim}13.1%$로 단독 효모균주를 사용한 것의 $5.2{\sim}7.2%$ 보다 높게 나타났으며, 발효도 단독 효모균주 첨가구에 비하여 양호하여 단독효모보다는 누룩과 효모를 혼합하여 첨가한 것이 벌꿀주 발효에 더 효과적이었다.
