中文摘要：本研究采集了我国华北平原玉米胚芽样品69个、实验室玉米胚芽加工制品样品40个、工厂粗玉米油样品30个及超市精玉米油样品40个，并通过HPLC结合紫外检测和免疫亲和柱，分析了样品中的脱氧雪腐镰刀菌烯醇(DON)。结果表明，玉米油中的DON污染不严重或不普遍，健康风险较低。
外文摘要：69 maize germ samples from North China Plain, 40 processed products of maize germs obtained in lab, 30 crude corn oils from factories and 40 refined corn oils from supermarkets in China were analyzed of deoxynivalenol (DON) by HPLC combined with ultraviolet detection and immunoaffinity column. 95.7% of maize germs were contaminated by DON. The average content was 449.0 μg/kg. The average of DON in processed products of maize germs including solvent extracted oil, cold-press oil, meal and cake was 163.7, 113.1, 1111.5 and 1175.2 μg/kg, respectively. Only 20% of crude corn oil and 12.5% of refined corn oil were contaminated by DON with the range of 67.5-340.5 μg/kg and 57.1-207.5μg/kg, respectively. During the production of corn oil, solvent extraction oil had a larger amount of DON than pressing oil. The contamination of DON in corn oil was not serious or widespread, which indicated a low risk of health.
