摘要
对"新红星"苹果进行1-甲基环丙烯(1-MCP)、自发气调包装(MAP)与乙烯吸收剂(EA)处理,然后于0℃下冷藏,研究不同处理在冷藏270 d后20℃货架期果实品质的差异。结果表明:贮后货架期间,"新红星"苹果果实硬度和可滴定酸含量下降,可溶性固形物含量无明显变化,虎皮病增多;MAP包装与1-MCP+EA+MAP能较好维持冷藏期间"新红星"苹果果实硬度,同时1-MCP+EA明显降低了冷藏期间虎皮病病情指数、显著降低了果实乙烯释放量和呼吸速率,并且抑制果皮α-法尼烯及共轭三烯的生成。综合分析认为,1-MCP+EA+MAP处理能较好维持"新红星"苹果冷藏和货架期间的品质,并能显著控制果实虎皮病的发生。
The‘Starkrimson’apple was treated with 1-methylcyclopropene(1-MCP), ethylene absorbent and modified atmosphere package(MAP) and then placed at 0 ℃ for cold storage, after 270 days, the quality difference of fruit with different treatments during shelf life at 20 ℃ was investigated. The results indicated that the firmness and titratable acid(TA) content of the apple decreased, soluble solid content(SSC) had no significant change, and superficial scald of peel were enhanced during shelf life after cold storage. MAP and 1-MCP+EA+MAP treatment effectively maintained fruit firmness during cold storage, and at the same time,1-MCP+EA treatment decreased the indexes of superficial scald, ethylene evolution and respiration rate significantly, and inhibited the formation of α-farnesene and conjugated trienol in peel. The comprehensive analysis suggested the 1-MCP+EA combined with MAP treatment effectively maintained the quality of ‘Starkrimson’apple during cold storage and shelf storage, and significantly reduced incidence of superficial scald.
