摘要:

以丰水梨果实为试材,研究(0 ± 0.5)℃条件下自发气调(MAP)结合不同1-MCP 添加量处理以及近冰温贮藏对果实保鲜效果的影响。结果表明:丰水梨不宜裸果贮藏,0.02mm PE 和0.04mm PVC 膜MAP 结合0.5μL/L1-MCP 处理对丰水梨果实起到良好的防褐保鲜效果,丰水梨较耐CO2,能忍耐3.0%~4.0% CO2 而不发生伤害。结果表明:果实硬度与PG 活性在P ≤ 0.05 水平显著负相关,- 1℃低温贮藏丰水梨150d 左右能维持果实较好的品质和风味,果实在0℃贮藏期为120d 左右。

Abstract:

Housui pears were used as the raw materials to investigate the preservative effects of modified atmosphere package (MAP) bags coupled with 1-MCP treatment at different concentrations and near-freezing point storage. Results indicated fruits could maintain excellent quality in 0.02 mm PE and 0.04 mm PVC bags coupled with 0.5 μL/L 1-MCP treatment. In addition, Housui pears exhibited high CO2-resistant capability and no harm was observed under the condition of 3.0%-4.0% CO2. Fresh firmness was negatively correlated with polygalacturonase (PG) activity (P ≤ 0.05). Housui pear could maintain excellent quality and flavor for 150 days at - 1 ℃, and approximately 120 days at 0 ℃.

Key words: Housui pear, modified atmosphere package(MAP), 1-MCP, near freezing storage, quality
