초록

풋감을 30일간 저온저장(7℃) 및 냉동저장(-20℃)하면서 성분의 변화를 조사하였다. 수분, 단백질, 지질, 탄수화물 등의 일반성분은 저장방법이나 저장기간에 따른 변화가 없었으며, 조섬유 함량은 냉동저장시는 거의 변화가 없었으나 냉장저장시는 저장기간이 길어짐에 따라 약간씩 감소하였다. 폴리페놀 함량은 냉장, 냉동저장에서 모두 증가하였으나 냉동저장의 경우 증가 폭이 매우 컸다. 총펙틴 함?c은 저장기간이 연장에 따라 감소하였고 수용성 펙틴 함량은 증가하였는데 냉동저장인 경우는 그 증가나 감소 정도가 매우 적었다, 탄닌 함량은 냉동저장시는 거의 변하지 않았으나 냉장저장한 경우는 크게 감소하였다.

We investigated the changes of composition in immature green persimmon during cold(7℃) and freezing (-20℃) storage for 30 days. Mosture, protein, fat and carbohydrate were not significantly different by storage temperature and storage days. Crude fiber had little change during freezeing storage, but in case of cole storsge, as storage time goes by, it slightly decreased. Content of polyphenol was increased during cold and freezing storage, expecially during cold storage it was remarkably increased. Content of total pectin was decreased, while content of soluble pectin was increased during cold storage. Content of total pectin and soluble pectin was sligltly decreased or increased during freeze storage. Content of tannin had little change during freezeing storage but it significantly decreased during cold storage.
