不同保鲜膜对元帅苹果常温贮藏效果的影响

摘要

为延长苹果贮藏时间，以元帅苹果为试材，研究了3种不同参数保鲜膜包装对苹果常温贮藏效果的影响。结果表明：保鲜膜包装元帅苹果与对照相比，可以延缓可溶性固形物、可滴定酸含量、硬度以及失重率的下降，并对细胞膜渗透率也有一定的控制作用。在3种保鲜膜中，保鲜膜2的贮藏效果要好于保鲜膜1和3。但使用保鲜膜包装贮藏果实，乙烯浓度会大幅度增加，对贮藏不利。%In order to prolong the apples storage time ,taking Yuanshuai apples as materials ,the storage effects of different fresh-keeping film on preservation were studied .The results showed that compared with CK ,the apples covered with fresh-keeping film could delay the decreaseing of soluble solids ,titratable acid content , firmness and weight loss rate ,it had little control effect on membrane permeability .The storage effects of fresh-keeping film 1 was better than fresh-keeping film 2 and 3 .However apples packaging with fresh-keeping film was would increase ethylene concentration and would be unfavorable for storage .
