摘　　要：针对花生表面存在的黄曲霉毒素污染问题,考察了微波光波组合辐射处理对花生表面黄曲霉毒素B_1(AFB_1)的降解效果。将花生在一定微波光波辐射频率下进行试验,研究结果表明:微波光波联合辐射法可有效降解花生表面的AFB_1,并随着时间增加,毒素减少量也增加,8min时降解率达到74.06%;AFB_1降解速率与样品最初被污染的水平有关;经该法处理后的花生,其基本成分变化不大.营养成分损失较少。由于微波光波组合辐射法降解条件温和、操作简单、降解效率高,可应用于受黄曲霉毒素污染的粮食物料中。For problem of contaminated peanut with aflatoxin, effect of microwave-lightwave combined treatment on degradation of aflatoxin B1 in peanut was studied. Resuhs of experiment indicated that method of microwave and lightwave combined treatment could effectively degrade AFB1 in peanut, degradation level of AFBt in peanut incrcased with treatment time, and under condition of 8 min, degradation rate of AFB1 was 74.06%. Degradation rate of AFB1 was related to initial level of contamination. Basic ingredients of peanut changed little, and less nutrition was lost. Since method was under soft condition, simple and efficient, it could be applied to the crops contaminated with aflatoxin.
