| 摘 要： | 以普通PE膜包装和单果纸包装作为对照，研究冷藏条件下微孔保鲜膜对鸭梨果实贮藏效果的影响。结果表明，在整个冷藏期间，微孔包装袋内二氧化碳浓度在0～0．6％之间，而普通PE膜包装袋内二氧化碳浓度在1．1％-3．2％之间。采用微孔保鲜膜包装果实的果心果肉褐变指数明显低于普通PE膜包装，与纸包装相似。同时，微孔保鲜膜包装果实的失重率和果皮缩皱指数明显低于纸包装。除普通聚乙烯膜包装的果实内可滴定酸含量略偏高外，3个处理的可溶性固形物（TSS）和可滴定酸（TA）含量没有明显区别。与普通PE膜包装和单果纸包装相比，微孔保鲜膜包装在鸭梨的贮藏保鲜方面具有明显的优势。

| Abstract: | Storage effects of ya pear (Pyrus bretschneideri Rehd. cv.yali) packaged with micro-perforated LDPE film at low temperature were investigated, with the control treatments of ya pear wrapped with copy paper and packed with normal LDPE film. The results showed that, during the whole storage period, the CO2 level in the normal film package was in the range of 1.1%~3.2% and the CO2 level in micro-perforated film package was 0~0.6% respectively. The package with micro-perforated film was capable of reducing the ... |
