摘要/Abstract

摘要： 从酚类物质酶促褐变、呼吸强度、乙烯释放量、果皮色泽、果实品质和衰老等方面研究了1-MCP对黄金梨防褐保鲜效果，并评价1-MCP处理后自发气调(MAP)对黄金梨CO2敏感性的影响。结果表明：0．5 μL／L 1-MCP处理对果实的防褐保鲜效果较好，1．0 μL／L 1-MCP对果肉造成轻微的伤害；2个浓度1-MCP+0．02 mm MAP使果实产生不同程度的果肉和果皮褐变；黄金梨不宜用1-MCP+0．02 mm PE袋MAP贮藏，用0．5 μL／L 1一MCP挽口贮藏效果较好。

Abstract: This experiment was carried out with browning caused by enzyme reaction of phenolics respiration rate，ethylene production，fruit color，quality and senescence of ’Whangkeumbae' pear fruit to study effects of different 1-MCP concentrations on browning inhibition，and value the effects of modified atmosphere packaging (MAP) on CO2 sensitivity of fruit treated with 1-MCP．The results showed that 0．5 μL／L 1-MCP treatment was more effective on browning inhibition compared to control，and occurred slight browning offresh with 1．0 μL／L 1-MCP treatm ent．This study also showed that two concentrations of 1-MCP combined with MAP lead to browning of flesh and peel at different levels．1-MCP treatment combined with 0．02 mm PE bags was not suitable for storage of pear fruit．O．5 μL／L 1-MCP with unpackaged bag was recommended to storage of pear fruit.

Key words: 'Whangkeumbae' pear, 1-MCP, tissue browning, modified atmosphere packaging, CO2 sensitivity
