초록

떫은감 둥시를 이용한 감장아찌 제조 중 과육의 세포벽 성분과 연화효소의 변화를 조사한 결과, 알콜불용성 물질 및 세포벽 성분의 함량은 감장아찌 제조 시 간장 및 된장 침지 모두 침지 시간이 길어질수록 감소하는 경향을 나타내었으며, 침지 20일째까지는 완만하게 감소하였으나 30일 이후부터 급격한 감소가 발생하였다. 수용성 물질의 함량은 간장 및 된장 침지 모두 침지 기간이 증가할수록 점차 증가하는 경향을 나타내었다. Lignin, pectin 질 및 산 가용성 hemicellulose의 함량은 간장 및 된장 침지 장아찌 모두 침지 기간이 경과하여 숙성이 진행될수록 감소하였으나, 알칼리 가용성 hemicellulose는 침지시간이 길어질수록 증가하는 양상을 나타내었다. Cellulose의 함량은 간장 및 된장 침지 각각 침지초기의 $6.07{\pm}0.09\;mg/g$과 $6.18{\pm}0.13\;mg/g$에서 침지 50일째 $6.09{\pm}0.17\;mg/g$와 $6.28{\pm}0.32\;mg/g$으로 큰 변화를 나타내지 않았다. 감장아찌의 경도는 간장 및 된장 침지 모두 침지 30일째까지는 증가하다가 그 이후에는 감소하는 경향을 나타내었다. Polygalacturonase와 pectinesterase는 간장 및 된장 침지 모두 침지 10일째부터 효소활성이 증가하기 시작하였으며 침지 기간이 경과할수록 효소활성은 높아지는 것을 알 수 있었다. ${\beta}-Galactosidase$의 경우도 간장 및 된장 침지 모두 침지 10일째부터 효소활성이 증가하기 시작하여 침지 30일째까지 완만한 상승을 나타내다가 침지 40일째부터 급격한 효소활성의 증대가 관찰되었다.

Changes of cell wall components and softening enzyme during the preparation of persimmon pickles with soy sauce and soy paste were investigated. The contents of alcohol insoluble substance and cell wall extracted from persimmon pickles in soy sauce and soy paste were gradually decreased to the 20th day of storage and then decreased rapidly, but the contents of water soluble material extracted from persimmon pickles in soy sauce and soy paste was increased during the storage time $(0{\sim}50\;days)$. The contents of lignin, pectin and acid-soluble hemicellulose of persimmon pickles in soy sauce and soy paste were decreased during the storage, but contents of alkali-soluble hemicellulose was increased. The contents of cellulose almost did not change during storage of pickles. The hardness of persimmon pickles in soy sauce and soy paste was gradually increased up to the 30th day of storage and then decreased. The activities of polygalacturonase and pectinesterase as softening enzyme in persimmon pickles with soy sauce and soy paste increased during storage. And ${\beta}-galactosidase$ activity was slightly increased to the 30th day of storage and after increased rapidly.
