초록

The changes of the contents of acetaldheyde and alcohol in Chungdo Bansi was determined during the removal of astringency by treatment of $CO_2$. On the other hand, the difference of acetaldehyde and alcohol contents were determined to comparedits contents in the part of Chungdo Bansi and Buju, respectively. It showed that the variation of acetaldehyde and alchohol contents was higher 10 times non-astringent persimmon than astringent one, and acetaldehyde and alcohol contents in the core of non-astringent persimmon and sweep one were the higher than the other parts. It was assumed that acetaldehyde and ethanol contents had intimately relation to removal of astringency.
