Effect of different temperatures on the storage quality of Pleurotus eryngii

Taking Pleurotus eryngii as the material,the experiment was carried out. In the experiment,P. eryngii was stored in 2,4,6,8,10 and 12 ℃. The effects of different storage temperatures on postharvest physiology and quality of P. eryngii were studied under different storage temperatures. The results showed that P. eryngii stored at 2 and 4 ℃ preferably maintained the activities of superoxide dismutase(SOD)(p<0.01) and catalase(CAT)(p <0.05),inhibited effectively the rapid erosion of protein,VCand total sugar,and rapid increasing of malondialdehyde(MDA)(p<0.01),reduced effectively the activity of polyphenol oxidase(PPO)(p<0.05),and delayed quality deterioration and aging process. Thus,2 ~4 ℃ was suitable for storage of P. eryngii,which provide a theoretical basis for the storage and preservation.
