摘要: 对‘红富士’苹果进行1.0 μL/L 1-甲基环丙烯(1-methylcyclopropene,1-MCP)和自发气调包装(modified atmosphere package,MAP)处理,继而进行0 ℃冷藏和20 ℃货架贮藏。结果表明:贮藏期间,‘红富士’苹果果实硬度和可滴定酸含量下降,可溶性固形物含量升高,虎皮病和果心褐变增多。1-MCP处理能较好维持冷藏期间‘红富士’苹果果实硬度和可溶性固形物含量,降低了包装内CO2和乙烯含量。同时,1-MCP明显降低了冷藏期间虎皮病发病指数、果心褐变指数以及果柄端果肉褐变率,显著抑制果皮α-法尼烯及共轭三烯的生成。1-MCP+MAP结合使用可较好维持果实可滴定酸含量和果皮色泽、抑制果柄端果肉褐变。综合分析认为,1-MCP+MAP处理能较好维持‘红富士’果实冷藏和货架期间的品质,并显著抑制果实虎皮病的发生。

Abstract: Freshly harvested ‘Red Fuji’ apples were treated with 1-methylcyclopropene (1-MCP) at 1.0 μL/L subjected to modified atmosphere package (MAP), and then stored initially at 0 ℃ for 210 days and subsequently until the end of shelf life after switching to 20 ℃. The results indicated that the apple fruits showed decreased firmness and titratable acid (TA) content and increased soluble solid content (SSC), and developed superficial scald and core and stem-end flesh browning during storage. 1-MCP treatment effectively maintained higher fruit firmness and SSC during cold storage, and reduced CO2 and ethylene contents in the packaging bag. 1-MCP also decreased significantly the incidence of superficial scald and stem-end browning significantly (P < 0.05), as well as the contents of α-farnesene and conjugated trienol in peel. 1-MCP + MAP could maintain the TA content of apples and the fresh color of peel and decrease stem-end browning. Taken together, it was suggested that the 1-MCP + MAP treatment effectively maintained the quality of ‘Red Fuji’ apples during cold storage and subsequent shelf life, and significantly reduced the incidence of superficial scald.
