利用不同剂量的高能电子束和γ射线进行辐照处理，研究了2种射线对不同状态下黄曲霉毒素B1（Aflatoxin，AFB1）的辐射降解效果和对小麦面粉粉质指标的影响。结果表明：高能电子束和γ射线辐照处理，能够降解不同状态下的 AFB1，辐照剂量越大，降解率越高，AFB1浓度越高，辐射降解率越低；相同处理剂量对溶液中黄曲霉毒素 B1的降解作用，大于对污染小麦中 AFB1的降解作用。2种辐照处理方式对面团吸水率、形成时间、稳定时间等小麦粉质指标产生了显著的影响，其中高能电子束射线的作用强度大于γ射线。

After radiating with high energy electron beam and gamma -ray at different doses,the degra-dation rates of aflatoxin B1 in methanol -water solution and contaminated wheat were studied,and the farino-graph indexes of wheat flour was determined.The results showed that the two irradiation methods could both effectively degrade aflatoxin B1 in different states.The bigger the radiation dose was,the higher the degrada-tion rate was,and the greater the aflatoxin B1 concentration was,the lower the degradation rate was.Under the same radiation dose,the degradation of aflatoxin B1 in methanol -water solution was much easier than that in contaminated wheat.Compared to the non -irradiation treatment,the two irradiation methods both signifi-cantly affected the dough water absorption rate,development time and stability time,and the effect of high en-ergy electron beam was more effective than that of gamma -ray.
