摘　　要：以人工栽培的新鲜鸡腿蘑为试材,研究了薄膜包装冷藏对鸡腿蘑采后生理变化的影响。结果表明:鸡腿蘑具有明显的呼吸高峰,属于呼吸跃变型蔬菜。在(1±0.5)℃的冷藏温度下,厚度为0.05mm的聚乙烯薄膜袋包装,既推迟了鸡腿蘑呼吸高峰的到来又降低了峰值,且有效控制了鸡腿蘑失重率、褐变度、膜透性和PPO活性的增加,从而延缓了鸡腿蘑的衰老进程,有利于其贮藏保鲜。Effects of different film packaging and temperatures on the postharvest physiology of Coprinus comatus were studied. The results showed that：Coprinus comatus had typical respiration peak. The treatment with 0.05mm PE film packing at （1±0.5）℃ could delay the appearance of respiration peak and lower the respiration rate. During storage, the weight loss, browning degree, cell membrane permeability and PPO activity were effectively controlled, and thus extending the freshness of Coprinus comatus.
