摘要
本试验以羧甲基纤维素可食性膜作为生仿酵母菌的载体,研究生物涂膜剂对库尔勒香梨贮藏生理及效果的影响,以期研究出一种天然、无毒、高效的生物涂被保鲜剂。结果表明:涂被保鲜剂处理库尔勒香梨,抑制了果实的呼吸强度、叶绿素分解、PPO活性和MDA的积累,降低果实的腐烂率,显著延缓了果实的后熟软化。加入生仿酵母CMC+Yc-b后,能强化CMC的防腐保鲜作用,明显降低了果实的失重率,有效地抑制了可溶性固形物的降解,保持了果肉硬度,在15℃条件下,贮藏2个月,好果率达95%,处理效果最好。
Kuerle”pear treated with CMC edible coating carrying yeast was used as raw material in this experiment. Throughthe study on effects and physiology of storage, a kind of natural, no-toxic, highly efficient biological coating was found out. The resultsshowed that all the treatments had restrained respiratory intensity, chlorophyll decomposition, PPO activity and MDA accumulation,reduced rot rate and postponed ripeness and softness. CMC+Yc-b combined with yeast could strengthen antiseptic effect remark-ably. Stored at 15℃,rate of rotting and loss of “kuerle”pear still remained low at 5% after two months storage.
