【摘要】In order to determine optimal packing methods for Pleurotus nebrodensis, the effects of packages including different thickness polyethylene(PE) film, micro-perforated film, vacuum packaging with PE film, PE film flushed with nitrogen on the quality of Pleurotus nebrodensis stored at 0°C were investigated. Compared with other packaging methods, 0.035 mm PE film flushed with nitrogen was better for the quality of Pleurotus nebrodensis during cold storage, which got a higher score of sensory evaluation, and obviously reduced the activities of PPO, POD and the browing degree, delayed the aging process and membrane lipid peroxidation during storage. Meanwhile, compared with conventional PE film packaging, 0.035 mm PE film flushed with nitrogen could extend storage time by 10-15 days. The results can provide a theoretical basis for cold storage of Pleurotus nebrodensis.%研究不同包装方式对白灵菇低温贮藏过程中品质的影响,0℃贮藏条件下,以白灵菇为试材,研究了不同厚度PE膜,微孔膜,PE膜结合抽真空,PE膜结合抽真空后充氮气等处理对白灵菇保鲜效果的影响.结果表明,与其他包装方式相比,用0.035 mmPE抽真空充氮气方式进行贮藏效果显著,较好地保持白灵菇原有的外观品质,降低了白灵菇贮藏期间PPO和POD活性,抑制
了白灵菇的褐变,延缓了贮藏期间白灵菇的衰老进程及膜脂过氧化程度,与常规PE 膜包装相比,延长白灵菇保鲜期10～15 d,为白灵菇的贮藏保鲜提供理论依据.【总页数】6页(P377-382)
