Quality characteristics of non steamed oriental melon Makgeolli by adding sucralose

This study examined the physicochemical quality characteristics of the oriental melon Makgeolli variant by addition of sucralose during its non-steamed fermentation process. The results showed a partial increase in initial sugar content in Makgeolli depending on the level of sucralose addition; and this slight increase in sugar content was exhibited in all intervals into which the sucralose was added during fermentation. The pH of Makgeolli did not exhibit significant changes according to the level of added sucralose until the fourth day of the fermentation process; and the total acidity of Makgeolli did not significantly change in accordance with the varied levels of added sucralose. Reducing sugar rapidly decreased in all intervals of the experiment during the first day of fermentation, and it was then increased slightly staring from the second day of the fermentation. Alcohol content in all experimental intervals was proportionally increased in accordance with the amount of added sucralose during the alcoholic fermentation process. The alcohol content was reached to the final alcohol contents of control (A) 11.27%, 0.001% (w/w) (B) 11.43%, 0.002% (w/w) (C) 11.80%, and 0.003% (w/w) (D) 12.23%. The levels of acetaldehyde, 1-propanol, isobutanol, and isoamyl alcohol in Makgeolli were all proportional to the level of the amount of sucralose added in the fermentation process. The organoleptic characteristics of Makgeolli was accorded with the level of the amount of sucralose. In the sensory evaluation, the experimental interval of 0.003% (w/w) (D) showed the highest scores of 3.30, 2.67, 3.17, and 3.20 in color, odor, taste and overall, respectively.

Sucralose 첨가에 따른 참외 생쌀발효 막걸리의 품질특성

본 연구에서는 비열처리 참외막걸리 제조과정 중 sucralose첨가량에 따른 이화학적 품질 특성을 조사하였다. 그 결과 초기 당도는 sucralose 함량이 높을수록 일부 증가하였으며 발효가 진행됨에 따라 모든 첨가구간에서 조금씩 증가하는 경향을 보였다. pH는 발효 4일까지 sucralose 함량에 따른 큰 차이가 없었으며 총산도의 경우도 sucralose 함량에 따라 큰 차이가 나타나지 않았다. 환원당의 경우 1일째에 모든 실험구간에서 급격히 감소한 뒤 2일부터 조금씩 증가하는 경향을 보였다. 알코올함량은 sucralose의 첨가량에 따라 알코올발효가 진행되면서 알코올함량이 증가하여 발효 종료 후 무첨가(A) 11.27%, 0.001%(w/w) 첨가군(B) 11.43% 0.002%(w/w) 첨가군(C) 11.80% 및 0.003%(w/w) 첨가군(D) 12.23%로 나타났다. 알코올성분 중 acetaldehyde, 1-propanol, isobutanol 및 isoamylalcohol 모두 sucralose첨가량에 많을수록 높은 함량을 보였다. Suralose 첨가에 따른 관능적 특성은 sucralose 0.003%(w/w) 첨가군(D)에서 color, odor, taste 및 overall이 각각 3.30, 2.67 3.17 및 3.20으로 가장 높았다.
