Pre-drying of ‘Fuyu’ persimmon was performed right after harvesting from a farm. Pre-drying conditions were varied with room temperature (RT) for 1 day to 7 days, low temperature (LT, at 20~30oC) for 1 day to 4 days, high temperature (HT, at 30~40oC) for 3 h to 12 h, and ultra-high temperature (UT, at 50~60oC) for 30 min to 120 min. Weight loss of pre-dried persimmon was increased from 1.62% up to 2.96% with increased pre-drying temperature and time. Predrying at RT resulted more significant weight loss of persimmon compared to that of pre- drying at HT. Minimum firmness loss of persimmon stored at 0oC for 100 days was obtained at the condition of HT for 6 h. Rate of peel blackening was decreased from 31.5% to 16.4% and 10.9% by pre-drying at HT for 6 h and 9 h, respectively.
