In this study,pure water,ozone water,and fruit and vegetable detergent were used to wash roses before drying to investigate the effects of washing pretreatment on the physicochemical proper-ties of edible roses after washing and hot air drying.The results showed that:the total color difference and browning coefficient of roses were reduced by 30.82%and 12.52%respectively after washing by fruit and vegetable cleaners,and the edible roses obtained were of the best appearance quality com-pared with those washed by pure water and ozonated water.The maximal rate of hot-air drying after washing by ozonated water and fruit and vegetable cleaners was enhanced by 19.23%~39.23%and 27.59%~38.38%respectively compared with those washed by pure water,the rehydration capacity increased by 3.32%~5.69%and 0.57%~2.46%,and the retention of nutrients increased.
