以寒富苹果为试材,研究了(MA)包装和MA包装结合1-MCP处理对冷藏后寒富苹果果实货架期贮藏特性的影响。结果表明:浓度为0.75μL/L的1-MCP处理结合MA包装有利于降低果实呼吸强度和乙烯释放量,延迟呼吸峰值和乙烯释放峰值出现的时间,延缓果实硬度和可滴定酸含量的下降、抑制可溶性固形物含量的上升速度。同时还延缓了果实中MDA含量和电导率的升高速度。保鲜袋厚度对果实贮藏特性影响不大。因此认为,1-MCP处理结合MA包装(0.02 mm)能较好地抑制货架期果实生理代谢水平,保持果实品质。

Effects of different treatments on storage characteristic of 'Hanfu' apple during shelf life after cold storage were investigated.Hanfu apple were treated with different thickness plastic package and different film package after 1-MCP treatment(0.75μL/L,20h).The results showed that 1-MCP treatment with MA package inhibited the respiratory rate and ethylene production rate,and delayed the peak value time of 'Hanfu' apple during the shelf life after cold storage(6 months).It also restrained the decline of fruit firmness and titratable acid content,delayed the raise of soluble solid contents.The increase speed of MDA and relative conductivity were postponed.The thickness of plastic package had no significant effect on the quality.Therefore,the results suggested that MA packaging combined with 1-MCP treatment has the potential to inhibit the physiology level and extend the shelf life of 'Hanfu' apple after cold storage.
