摘　　要：探究不同剂量(0、0.3、0.6、0.9、1.2 kGy)电子束转靶X射线(electron beam generated X-ray,EBGX)辐照处理对(15±1)℃贮藏条件下双孢菇采后贮藏品质的影响。结果表明,与未处理组相比,EBGX处理在延缓质量损失、维持表观颜色、质构特性、促进酚类物质积累等方面具有显著效果。与其他辐照剂量相比,0.9 kGy处理能够有效延缓超氧阴离子自由基产生速率,减少双孢菇贮藏过程中活性氧的积累,增强超氧化物歧化酶、过氧化氢酶活性,抑制微生物生长。表明EBGX处理能够有效延缓双孢菇贮藏过程中的品质劣变现象。本研究为EBGX处理在双孢菇保鲜中的应用提供了理论依据。This study investigated the effect of electron beam generated X-ray(EBGX)irradiation at different doses(0,0.3,0.6,0.9 and 1.2 kGy)on the storage quality of harvested Agaricus bisporus at(15±1)℃.The results indicated that EBGXtreated mushroom had significant superiority in delaying mass loss,maintaining apparent color and textural properties,and promoting phenol accumulation compared with the non-treatment group.Different from the other irradiation doses,the 0.9 kGy treatment effectively delayed the rate of superoxide anion radical production,reduced the accumulation of reactive oxygen species(ROS),enhanced the activities of superoxide dismutase(SOD)and catalase(CAT),and inhibited microbial growth.It is suggested that EBGX treatment can obviously delay the quality deterioration of A.bisporus during storage.This study provides a theoretical basis for the application of EBGX treatment in the preservation of A.bisporus.
