We investigated the changes of composition in immature green persimmon during cold(7$^{\circ}C$) and freezing (-2$0^{\circ}C$) storage for 30 days. Moisture, protein, fat and carbohydrate were not significantly different by storage temperature and storage days. Crude fiber had little change during freezing storage, but in case of cold storage, as storage time goes by, it slightly deceased. Content of polyphenol was increased during cold and freezing storage, especially 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 slightly decreased or increased during freeze storage. Content of tannin had little change during freezing storage but it significantly decreased during cold storage.
