Abstract:With the deepening of the research on postharvest preservation of fruits in China，ethanol is widely used as a preservative in postharvest preservation.Treating postharvest fruits with ethanol can effectively extend their shelf life.This paper briefly reviewed two ethanol treatment methods（ethanol fumigation treatment，ethanol compound preservation） of postharvest fruits，in terms of fruit internal and external quality and postharvest resistance to pests and diseases.Finally，the research status，existing problems and prospects of this field were expounded，which would provide a basis for the application of ethanol in fruit preservation after harvest.
