气调包装与1-MCP结合抑制苹果蜡质成分降低

为了探讨红富士苹果在贮藏过程中主要蜡质成分特别是与油腻相关的蜡质成分变化,以及贮藏过程中果实主要品质指标的变化规律,研究了聚氯乙烯袋(PVC)自发气调包装(MAP)与1-甲基环丙烯(1-MCP)结合处理(MAP+1-MCP)对(0±1)℃冷藏过程中红富士苹果蜡质成分和果实贮藏品质的影响。结果表明:在贮藏过程中,对照(不做任何处理)的蜡质总量一直降低,MAP和MAP+1-MCP处理的在贮藏一个月后升高,随后贮藏的过程中降低。所有处理和对照中,二十九烷和二十七烷含量降低,十六烷酸和9,12-十八碳二烯酸含量升高,二十九-10-醇和二十九-10-酮含量先降低再升高。MAP和MAP+1-MCP能够抑制...

Summary:为了探讨红富士苹果在贮藏过程中主要蜡质成分特别是与油腻相关的蜡质成分变化,以及贮藏过程中果实主要品质指标的变化规律,研究了聚氯乙烯袋(PVC)自发气调包装(MAP)与1-甲基环丙烯(1-MCP)结合处理(MAP+1-MCP)对(0±1)℃冷藏过程中红富士苹果蜡质成分和果实贮藏品质的影响。结果表明:在贮藏过程中,对照(不做任何处理)的蜡质总量一直降低,MAP和MAP+1-MCP处理的在贮藏一个月后升高,随后贮藏的过程中降低。所有处理和对照中,二十九烷和二十七烷含量降低,十六烷酸和9,12-十八碳二烯酸含量升高,二十九-10-醇和二十九-10-酮含量先降低再升高。MAP和MAP+1-MCP能够抑制蜡质总量和其他成分相应的变化。MAP和MAP+1-MCP均能延缓果实硬度的下降、可溶性固形物和可滴定酸的降解速度,降低固酸比率和失重率,抑制呼吸速率和乙烯释放速率,且可以抑制苹果贮藏后期油腻的发生。无论从对蜡质成分的影响,还是对果实贮藏品质的影响来看,MAP+1-MCP的效果优于MAP。PVC气调包装结合1μL/L1-MCP是较为理想的长时间保鲜红富士苹果的处理方式。研究结果可为生产上科学有效的长期贮藏红富士苹果、解决贮藏后期果实油腻问题提供参考。

Modified atmosphere packaging (MAP) is a very useful method in postharvest storage for fruits and vegetables by altering the gaseous environment of the stored commodities. 1-methylcyclopropene (1-MCP) is a potent inhibitor of ethylene action, and has been extensively researched in a variety of horticultural crops, especially climacteric fruits. Greasiness is a problem for apples following their prolonged storage. At present, the storage quality and physiology property of fruits and vegetables treated with MAP or a combination of MAP and 1-MCP have been studied, however, there are few reports about the effects of MAP or a combination of MAP and 1-MCP on the wax composition of an apple during storage. The objective of this study was to study the changes of primary wax composition during storage and the relationship
