摘　　要：分别用0.03 mm PE无孔膜、0.03 mm PE微孔膜、0.05 mm智能呼吸膜对采后鲜金针菇进行包装,并置于低温(4℃)和冰温(-0.5℃)条件下贮藏,通过测定贮藏过程中金针菇失重率、可溶性固形物含量、Vc含量、色差、细胞膜渗透率及可溶性蛋白质含量的变化,研究不同贮藏条件对金针菇品质的影响。结果表明,冰温贮藏优于低温贮藏,智能呼吸膜包装优于两种PE膜包装,其中冰温条件下智能呼吸膜包装对金针菇的保鲜效果最优,能够长时间保持菇体品质,使金针菇贮藏期延长至30 d左右。The postharvest fresh Flammulina velutipes were packed with 0.03 mm PE non-porous film, 0.03 mm PE microporous film,intelligent breathing film respectively,and stored at low temperature（4 ℃）and controlled freezing-point（-0.5 ℃）.The effects of different storage conditions on the quality of Flammulina ve-lutipes were studied by determining the change of weight loss,soluble solids content,Vc content,color,cell mem-brane permeability and soluble protein content of Flammulina velutipes in the process of storage.The results showed that the controlled freezing-point temperature storage was better than that of low temperature storage,in-telligent breathing film packing storage was better than that of the other two PE film packaging storage.The fresh-keeping effect of intelligent breathing film package at controlled freezing-point was the optimal.It could extend the storage time of Flammulina velutipes to a long time of 30 days.
