Abstract: 【Objective】 To explore the most suitable storage conditions of "rock candy heart" apples in Aksu area. 【Methods】 Apples in Aksu area were used as material to monitor the changes of various fruit quality indexes during the process of apple core disappearing and browning under different storage conditions. 【Results】 After 100 days of storage, the sugar core rate and the sugar core index were significantly higher and the browning index was significantly lower than those of other storage conditions.There was no significant difference in PPO (Polyphenol oxidase) activity, ethanol, methanol and acetaldehyde content of fruits under different storage conditions.The sugar-core index of fruit was positively correlated with hardness, soluble solid, organic acid and PPO activity. 【Conclusion】 The temperature of 4℃ and perforation are the most favorable conditions for the storage of sugar-core apples in Aksu area.
