Objective

To investigate the preservation effects of low temperature combined with 1-methylcyclopropene (1-MCP) and potassium permanganate treatments on ‘Dali’ Ziziphus jujuba Mill. fruits.

Methods

Firm-ripe ‘Dali’ Ziziphus jujuba Mill. fruits were selected and randomly divided into 3 groups. These were treated with 1 µL/L 1-MCP or saturated potassium permanganate, respectively, with an untreated group as the control. All fruits were stored at –1–0  ℃ for 75 d. The 11 indicators, including vitamin C content, firmness and cell membrane permeability, were measured every 15 d. Each indicator was analyzed with at least 3 replicates, and the mean values were reported.

Results

Both 1-MCP and potassium permanganate treatments significantly delayed the decline in vitamin C and titratable acid content, inhibited the increase in reducing sugar, and retarded the degradation of protopectin and the loss of firmness and crispness. They also suppressed the increase in cell membrane permeability and malondialdehyde content, while maintaining higher levels of total phenols, flavonoids and the activity of antioxidant enzymes such as peroxidase. Among them, the 1-MCP treatment demonstrated superior overall preservation effects.

Conclusion

Under low-temperature conditions, both 1-MCP and potassium permanganate treatments effectively reduce the respiration rate of Ziziphus jujuba Mill., help maintain its nutritional quality and antioxidant activity, and extend its shelf life. 1-MCP is identified as the optimal treatment for the storage and preservation of Ziziphus jujuba Mill..
