1-MCP结合薄膜包装对三华李低温贮藏的影响
Effect of 1-MCP combined with film packaging on the low-temperature storage of Sanhua plum
摘要
Abstract
[Objective]This study evaluated the effects of 1-methylcyclopropene(1-MCP)combined with 0.02 mm polyethylene(PE)film bagging on the postharvest storage and preservation of Sanhua plums under low-temperature storage.[Method]The fruits were subjected to the following treatments:1-MCP fumigation coupled with 0.02 mm PE film bagging(1-MCP+PE),0.02 mm PE film bagging alone(PE),and an untreated control(CK).All samples were stored at(6.5±0.5)℃for 40 days.The changes in appearance quality,nutrient substances,and antioxidant capacity were measured during storage.[Result]Compared with the control,the 1-MCP+PE treatment markedly delayed fruit senescence.Specifically,the decline in peel brightness was retarded,and the onset of red coloration was delayed by approximately 30 days.At the end of the 40-day storage period,the browning index of treated fruit was only 14.42%of that in CK,and the weight loss rate was reduced to 32.56%of that observed in the control.The accumulation of total soluble sugars was inhibited,while the soluble protein content remained stable throughout storage.MDA accumulation was significantly suppressed,with the final content 25.45%lower than that of CK.Furthermore,the activities of SOD,CAT,POD,and APX were enhanced in treated fruit;POD activity in the 1-MCP+PE group peaked at day 20,reaching a value 5.13 times that of CK.Consequently,the accumulation of H2O2 and O2·-was effectively inhibited;at day 30,the O2·-content in the treated fruit was only 73.91%of that observed in the control,indicating a delay in oxidative reactions and the resulting retardation of fruit ripening and senescence.In contrast,PE film bagging alone exhibited a significantly weaker preservation effect compared with the combined 1-MCP+PE treatment.[Conclusion]The combination of 1-MCP and PE film bagging effectively maintained the storage quality of Sanhua plums under low-temperature conditions,thereby providing a theoretical basis for the improvement of postharvest handling practices for this fruit.关键词
