摘要 【目的】研究1-甲基环丙烯(1-MCP)处理、1-MCP处理结合出库后乙烯利催熟对猕猴桃果实货架期品质的影响,为完善1-MCP在猕猴桃果实保鲜上的应用提供依据。【方法】以"秦美"猕猴桃为试材,用1.0μL/L1-MCP密闭处理24h后进行冷藏(1-MCP处理),出库后取部分1-MCP处理猕猴桃,用750倍液的乙烯利浸果催熟(1-MCP+乙烯利处理),以未经1-MCP处理的果实为对照,测定1-MCP处理、1-MCP+乙烯利处理和对照处理猕猴桃的呼吸速率、乙烯释放速率、果实硬度、可溶性固形物含量、可滴定酸含量和VC含量等指标。【结果】与对照相比,1-MCP处理可显著抑制货架期猕猴桃果实的呼吸速率和乙烯释放速率,有效延缓果肉硬度、可滴定酸含量及VC含量的下降,抑制可溶性固形物含量增加,保持果实的营养价值,但1-MCP处理果实在货架期间软化较慢,味道偏酸,食用品质降低。1-MCP处理结合出库后乙烯利催熟,猕猴桃果实的呼吸速率、乙烯释放速率、果肉硬度、可滴定酸含量、VC含量和可溶性固形物含量均介于对照和1-MCP处理果实之间,与对照相比,延长了贮藏期和货架期,与1-MCP处理相比,改善了货架期果实的风味。【结论】冷藏与1-MCP结合处理能延长猕猴桃的贮藏期,但1-MCP处理对果实货架期食用品质有不利影响,采取出库后乙烯利处理可以改善果实的食用品质。 【Objective】The study was to investigate the effects of 1-MCP and 1-MCP combined with Ethephon(after stored in(0±1)℃)treatment on the shelf-life quality of kiwi fruit to provide primary theory for improving the kiwifruit quality with 1-MCP.【Method】"Qinmei"kiwi fruit cultivars(Actinidia deliciosa C.F.Liang et A.R.Ferguson)were chosen to investigate the effects of 1.0μL/L 1-MCP and 1-MCP combined with 750 dilution Ethephon(after stored in(0±1)℃)treatment on the shelf-life quality of kiwifruit,with fruits not t...
