【摘要】 目的评估广西食用植物油中黄曲霉毒素B₁的暴露风险。方法结合广西植物油中黄曲霉毒素B₁污染状况和人群消费量的调查结果,应用暴露限值（margin of exposure,MOE）法对植物油中黄曲霉毒素B₁膳食暴露情况进行分析。结果此次调查中植物油样品黄曲霉毒素B₁含量范围为0.50³20.00μg/kg。其中,花生油的检出率为78.08%（114/146）,远高于其他植物油,超标率为31.51%（46/146）,平均含量为30.80μg/kg,人群日膳食暴露量为17.30 ng/kg BW,MOE值为18。定型包装花生油中黄曲霉毒素B₁平均含量为6.33μg/kg,低于国家安全标准,处于安全范围;而散装花生油黄曲霉毒素B₁平均为41.50μg/kg,含量高出国家标准1.08倍,人群日膳食暴露量25.59 ng/kg BW,MOE值为12,是定型包装的MOE值的1/8。结论对于散装花生油应优先采取风险管理措施,加大监管力度,并做好人群健康饮食习惯指导。更多还原

【Abstract】 Objective This report aims to assess the exposure risk of aflatoxin B₁ in edible vegetable oil in Guangxi.Methods By using margin of exposure（ MOE）,the report analyzes the dietary exposure of aflatoxin B₁ in edible vegetable oil with the data from contamination survey and dietary intake survey. Results For the vegetable oil sample,the content of aflatoxin B₁ was between 0. 50-320. 00 μg/kg. The detection rate of peanut oil was 78. 08%（ 114/146） which was higher than other vegetable oil,and the exceeding rate was 31. 51%（ 46/146）. For peanut oil,the average content was30. 80 μg/kg,the dietary exposure of the population was 17. 30 ng/kg BW,and the MOE was 18. For the prepackaged peanut oil samples,the average content of aflatoxin B₁ was 6. 33 μg/kg,which was below the limit. While for the bulk peanut oil,the average content of AFB₁ was 41. 50 μg/kg,which was more than 1. 08 times of the limit,and the dietary exposure was 25. 59 ng/kg BW. The MOE of bulk peanut oil was 12,1/8 of the prepackaged peanut oil. Conclusion Food safety regulators should pay more attention to bulk peanut oil products,the priority in the risk management measures.At the same time,related department should also promote healthy education for the residents.更多还原
