Sanhua plum fruit storing and fresh keeping method

The invention discloses a sanhua plum fruit storing and fresh keeping method, in which the sanhua plum fruit is stored under low temperature or normal temperature condition after being soaked with 0.05 mu g/L to 0.8 mu g/L 1-methylcyclopropene water solution in a sealed container. The invention determines the optimum use concentration of the 1-methylcyclopropene and the storage temperature of the sanhua plum fruit via selecting different concentration and storage temperatures of the 1-methylcyclopropene, obviously delays the senescence in the storage process after the sanhua plum fruit is picked and obviously improves the quality of the stored fruit, the fruit keeps higher hardness and the quantity of soluble solid state material and titratable acid, the speed of turning to red from green of the fruit is slowed down, the storage life of the sanhua plum fruit at room temperature and low temperature is prolonged (the storage period is prolonged), the quality and the commodity rate of the sanhua plum fruit are improved, the operation is simple, and method is popularized and applied easily.
