为探明适宜平菇安全无毒的保鲜方法，以平菇为试材，采用不同浓度的 Nisin 溶液对平菇进行处理，置于低温下（3℃）贮藏，研究天然生物保鲜剂 Nisin 对平菇贮藏品质的影响。结果表明：贮藏15 d 后，0．4 g/LNisin 处理的平菇失重率、多酚氧化酶活性、丙二醛含量分别低于对照1．22％、7．92 U/（min·g）、0．012μmol/g，保持了平菇的可溶性固形物含量和感官品质，从而延缓了平菇的衰老。

In order to explore a safe and nontoxic fresh-keeping method,P .ostreatus was treated with different concentrations of Nisin solution and then stored at 3℃ temperature,then the effects of natural biological preservative Nisin on storage quality of P .ostreatus.The results showed that the weightlessness rate,polyphenol oxidase activity and malondialdehyde content treated by 0.4 g/L Nisin were lower than the control group by 1.22% ,7.92 U/(min g)and 0.012 μmol/g respectively.Maintained a relatively high total solid substance content and sensory quality after stored for 15 d,and then prolonged the storage period of P .ostreatus.
