초록

본 연구에서는 전통누룩에서 분리한 S. cerevisiae 88-4를 이용하여 제조한 술의 증류방법에 따른 숙성 기간 중 품질 변화를 검토하고자 하였다. 8가지 조건에 따른 숙성 기간 180일까지의 알코올은 조금씩 감소하여 조건 8 (압력 -50 cmHg, 증류 온도 $60^{\circ}C$, 초류 7%, 본류 30%)의 경우 2.2%, 조건 1 (압력 -50 cmHg, 증류 온도 $50^{\circ}C$, 초류 0%, 본류 50%)의 경우는 0.4%의 알코올이 감소하였다. 2-싸이오바비트루산(TBA) 분석결과 숙성이 진행되면서 대부분의 증류주에서 TBA 값은 큰 변화가 없었으나 초기 알코올 농도가 낮았던 5 (압력 -60 cmHg, 증류 온도 $60^{\circ}C$, 초류 7%, 본류 50%), 6 (압력 -50 cmHg, 증류 온도 $50^{\circ}C$, 초류 7%, 본류 50%)번은 증가하였다. 노말프로판올(P), 아이소뷰탄올(B), 아이소아밀알코올(A) 분석결과 이후 숙성 기간이 증가함에 따른 노말프로판올 변화는 크지 않았으며 숙성 기간이 증가함에 따라 아이소뷰탄올은 감소하였으며 아이소아밀알코올은 변화가 없었다. 증류주의 숙성 기간별 향기성분은 각 증류주의 숙성에 따라 다양한 결과를 나타냈으며 조건 3 (압력 -60 cmHg, 증류 온도 $60^{\circ}C$, 초류 0%, 본류 30%) 증류주의 경우 위스키 향이 나는 아이소아밀알코올은 증류 0일차 이후에 조금 증가하였으며 달콤하면서 견과류의 향 특성을 나타내는 데칸산은 조금 감소하였다. 감각 검사 결과 숙성 기간에 따라 감각 결과에는 큰 차이 없었으며 종합적 평가($5.8{\pm}0.9$)가 가장 좋았던 3번 증류주의 감각 결과가 숙성 180일까지 이어졌다.

The current study reviews the manufacturing characteristics, upon aging, using different distillation methods with Saccharomyces cerevisiae 88-4 isolated from traditional Nuruk. The alcohol content slightly decreased at 180 days of aging period, under the conditions: -60 cmHg, distilling temperature $50^{\circ}C$, head cut 7%, and body cut 30%. The alcohol content decreased by 2.2% at: -50 cmHg, distilling temperature $60^{\circ}C$, head cut 7%, and body cut 30%. From 2-thiobarbituric acid (TBA) analysis, the TBA values were not found to change significantly in most of the alcohols, but increased at conditions of: -60 cmHg, distilling temperature $60^{\circ}C$, head cut 7%, and body cut 50% and -50 cmHg, distilling temperature $50^{\circ}C$, head cut 7%, and body cut 50%, when initial alcohol levels were low. According to n-propanol, iso-butanol, and isoamyl alcohol analysis, with increasing aging period, the n-propanol and isoamyl alcohol content did not change, although that of iso-butanol decreased. The flavor components showed different results based on the aging period. Results of sensory evaluation showed no significant difference based on aging. The sensory evaluation test was continued for 180 days at a condition of: -60 cmHg, distilling temperature $60^{\circ}C$, and body cut 50%, which had the best overall evaluation ($5.8{\pm}0.9$).
