- Abstract
To study the effects of 1-methylcyclopropene (1-MCP) combined with modified atmosphere packaging treatments on the storage quality of postharvest 'Palayingda' and 'Jilu' mangoes. Yuanjiang late-maturing mango varieties 'Palayingda' and 'Jilu' were used as the experimental material, and treated with 0.5 µL/L of 1-MCP, microporous membrane, PBI modified atmosphere packaging, 1-MCP combined with microporous membrane, and 1-MCP combined with PBI modified atmosphere packaging, and the changes in appearance index, weight loss rate, hardness, total soluble soild (TSS) content, VC content, titratable acid (TA) content, respiration intensity, commodity rate, and enzyme activities related to respiratory metabolism were examined and analyzed. The results showed that, during the storage at (13±1) °C, compared with the control group without any treatment, all five treatments could retard the increase of yellowing rate, disease index, decay rate, color difference, weight loss rate, soluble solids content and respiratory intensity of 'Palayingda' and 'Jilu' fruits in a certain period of time, inhibit the decrease in fruit hardness, VC content, TA content and commodity rate, and significantly suppressed the changes in enzyme activities related to respiratory metabolism in fruits. In comprehensive analysis, 1-MCP combined with PBI modified atmosphere packaging treatment was optimal for the preservation of 'Palayingda' and 'Jilu' mangoes during storage at (13±1)°C, which was more favorable for fruits storage. The results provide technical reference and scientific foundation for the preservation of late ripe mango in low latitude and high altitude areas.
