摘　　要：以广西“大白”番木瓜为试材,研究在常温(25±1)℃、相对湿度70%~80%条件下贮藏时,1-MCP结合两种包装处理对番木瓜贮藏品质的影响。采用单因素试验确定1-MCP的最佳处理浓度,再进行1-MCP分别结合硅窗袋、聚乙烯(PE)保鲜膜两种包装处理试验,通过测定相关指标得出番木瓜在常温下的最佳贮藏保鲜方法。结果表明:1-MCP处理番木瓜的最佳浓度是0.9μL/L。与对照组相比,1-MCP+硅窗袋处理后的果实贮藏时间为12 d,该处理方法可降低番木瓜的失重率,延缓番木瓜的色泽转变并保持良好的硬度;1-MCP+PE膜处理的番木瓜在贮藏期间可以有效降低番木瓜的失重率、转黄率和病害指数,较好地保持果肉的硬度,延缓营养物质的流失,抑制丙二醛(MDA)含量的上升,贮藏时间最长为18 d。通过综合分析得出,在两种处理方式中,1-MCP+PE膜处理对番木瓜的保鲜效果最好,有利于延缓番木瓜采后衰老和品质劣变,延长番木瓜的贮藏时间。The effects of 1-MCP combined with two packaging treatments on the storage quality of Guangxi“Dabai”papaya were studied when it was stored at room temperature(25±1)℃and relative humidity of 70%~80%.The single factor test was used to determine the optimal treatment concentration of 1-MCP,and then 1-MCP was combined with silicon window bag and polyethylene(PE)fresh-keeping film.The best storage and fresh-keeping method of papaya at normal temperature was obtained by measuring the relevant indexes.The results showed that the optimum concentration of 1-MCP was 0.9μL/L.Compared with the control group,the fruit storage time after 1-MCP+silicon window bag treatment was 12 days,and this treatment method could reduce the weight loss rate of papaya,delay the color change of papaya and maintain its good hardness.The papaya treated with 1-MCP+PE film can effectively reduce the weight loss rate,yellowing rate and disease index of papaya during storage,better maintain the firmness of the pulp,delay the loss of nutrients,and inhibit the increase of malondialdehyde(MDA)content,and the longest storage time is 18 days.Through comprehensive analysis,it can be concluded that 1-MCP+PE film treatment has the best effect on the preservation of papaya,which is beneficial to delaying the senescence and quality deterioration of papaya after harvest and prolonging the storage time.
