Abstract
In this research, Eshi 1 (PCNA, Chinese origin), Okitsu-20 (PCNA, Japanese origin), Mopanshi (PCA, Chinese origin) were used to identify the property of natural astringency-loss.
By the determination of the soluble tannin content, the insoluble tannin content and the size of tannin cells in fruits fresh, it was found that after the ethanol treatment of Eshi 1and Mopanshi, the soluble tannin content decreased while the insoluble tannin content increased with the tannin cells area reducing.
But for Okitsu-20, the tannin content and the size of tannin cells had no significant variation.
These results indicate that natural astringency-loss of Eshi 1 PCNA persimmon germplasm native to China is probably related with the soluble tannin coagulated into the insoluble tannin.
