The invention discloses a method for degrading aflatoxin in corn raw material. The method has the advantages that on the basis of the researches on the aflatoxin distribution and conversion rule in the whole process (from corn flour raw material and fermenting mash to mature mash and vinasse after fermentation) of ethanol production through fermentation, mycotoxin degrading agent is used for efficiently degrading the aflatoxin, the aflatoxin content in the vinasse can be lowered to satisfy the aflatoxin limit requirement (not more than 50 microgram/kg) required by national feed hygienic standard (GB 13078), the degrading process and a corn flour fermenting process are synchronous, an existing ethanol production process needs not to be changed, and the ethanol conversion efficiency is unaffected; the method is mild, safe, efficient, and suitable for degrading the aflatoxin in the ethanol production process which uses corn fermentation and is polluted by the aflatoxin. 本发明公开种玉米原料中黄曲霉毒素的降解方法。本发明在研究发酵生产乙醇的全过程（即从玉
