脱氧雪腐镰刀菌烯醇(deoxynivalenol,DON)是全球性的、最常见的谷物真菌毒素污染物,广泛存在于大麦、小麦、玉米等霉变粮食作物和动物饲料中~([1]),在我国,小麦及其制品受DON污染最为严重。2010年,王伟等对我国13省市售小麦粉的调查中发现DON在小麦粉中的污染率为100%,污染含量最高为2 995.10μg/kg~([2])。此外,玉米粉DON的污染也非常 Deoxynivalenol (DON) is the world’s most common cereal mycotoxin contaminants and widely found in mildewed food crops and animal feeds such as barley, wheat and corn (1) In our country, wheat and its products are the most polluted by DON. In 2010, Wang et al. Found that the contamination rate of DON in wheat flour was 100% and the highest pollution content was 2995.10μg / kg ~ ([2]). In addition, the contamination of corn flour DON is also very high
