采用200、400、600 μL/L的乙醇(乙醇溶液体积与泡沫体积比)对双孢蘑菇进行熏蒸处理，研究乙醇熏蒸处理对采后双孢蘑菇贮藏过程中品质的影响。结果表明，乙醇熏蒸处理能显著抑制双孢蘑菇呼吸强度，减少底物的消耗，延缓失重率和菌落总数的上升，有效缓解抗坏血酸(Vc)含量的降低，维持稳定的可溶性蛋白质含量，同时，显著降低总酚含量，可使双孢蘑菇保持较高的白度、硬度和感官评分，其中400 μL/L乙醇熏蒸保鲜效果最佳。

In order to study the effect of ethanol fumigation on the quality of postharvest Agaricus bisporus, Agaricus bisporus was treated by 200, 400 and 600 μL/L of ethanol during the fumigation. The results showed that ethanol fumigation could significantly inhibit the increase of respiration intensity, reduce consumption of the substrate, delay the increase of weight loss and total number of colonies, effectively alleviate the decrease of ascorbic acid (Vc) content, and maintain stable soluble protein content. At the same time, it can effectively reduce the total phenol content, maintain bisporus whiteness, hardness and sensory score. The 400 μL/L ethanol fumigation treatment showed the best preservation effect．
