The work aims to study the effect of different treatment methods on postharvest storage quality of passion fruit, so as to prolong the storage period of passion fruit. "Tainong No. 1" passion fruit was used as the experiment material and then subject to fumigation by 1-MCP and subsequently packed in PE30 bag with a film thickness of 30 μm. The packed fruit was stored at 8 ℃±0.3 ℃ for 50 days. On the 50th day, it was observed that the failure rate of untreated fruit was 45.13%, whereas the combined treatment resulted in a significantly lower failure rate of only 19.18%. These findings indicated that the combined treatment effectively prolonged the storage period of passion fruit. Furthermore, the utilization of PE30 packaging demonstrated its efficacy in delaying weight loss, respiration increase, as well as the decline of free amino acid and polyphenol content of the fruit. The combination of 1-MCP fumigation and PE30 packaging bag can effectively extend the postharvest storage period of passion fruit, in which PE30 packaging plays a crucial role.
