PRODUCTION OF DRIED PERSIMMON

摘要

PROBLEM TO BE SOLVED: To efficiently and stably conduct the post-ripening of harvested raw persimmons and to make the harvested persimmons become properly ripe to produce dried persimmon excellent in quality. SOLUTION: The method of this invention is to conduct the post-ripening of harvested persimmons, which have not yet been properly ripe, at 25-35 deg.C and 70-95% humidity. The raw persimmons are classified according to their size and ripeness degree and are assigned size parameters [i.e., (1.3) when big; (1.4) when medium; (1.7) when small] and ripeness degree parameters [i.e., (1) when nearly properly ripe; (1.7) when slightly immature; (2.4) when immature]. The time T (h) required for after-ripening is expressed by the formula: T=[24×(size parameter)×(ripeness degree parameter)]±12. It is possible to produce excellent dried persimmons having no astringency and excellent in color tone by effectively performing the post-ripening treatment of raw persimmons.
