摘要
以酥梨为试材,研究了酥梨贮藏初期缓降温阶段(40 d)采用1-MCP处理对梨果整个贮藏(0±0.5℃)及货架期(20℃)表皮生理和外观变化的影响。结果表明:与不做1-MCP处理相比,酥梨贮藏300 d时,经1-MCP处理的果皮α-法尼烯、共轭三烯、总酚含量和PPO活性分别降低了29.17%、39.43%、22.47%和24.45%;果皮细胞膜的损伤程度得到有效减轻,黑皮病的发生得到明显抑制,货架期黑皮指数仅有0.83%,极显著(P<0.01)低于对照(92.14%)。在酥梨采后缓降温阶段采用1-MCP处理不仅可使其冷藏期和货架期的黑皮指数降低36.96%和91.31%,而且能维持更好的新鲜程度和品质。
In Gradual Cooling Stage( 40 d),the effects of 1-MCP treatment on physiological and superficial qualities of ‘Dangshansu'pear peels in cold storage( 0 ± 0. 5℃) and shelf-life period( 20℃) were studied. The results show that,compared to‘Dangshansu'pears without 1-MCP treatment,1-MCP decreased the accumulation of α-farnesene,conjugated trienols,total phenols and the activity of PPO by 29. 17%,39. 43%,22. 47% and 24. 45%respectively,and alleviated the injury to cell membrane in the peels,and reduced the occurrence of superficial scald to0. 83% from 92. 14% remarkably( P 0. 01). 1-MCP treatment could significantly restrain the incidence of superficial scald of‘Dangshansu'pear,reduce the superficial scald by 36. 96% and 91. 31% and maintain the qualities better in cold storage and shelf-life period.
