为了解梧州市居民通过小作坊土榨花生油摄入黄曲霉毒素B1（AFB1）的膳食暴露风险，随机抽取梧州市3区、4县小作坊生产散装土榨花生油共496份,检测其AFB1含量，应用点评估方法评估梧州市居民的土榨花生油AFB1膳食暴露风险。结果表明：496份土榨花生油中，AFB1检出率为40.3%，含量在0.12~109.00 μg/kg之间，平均含量为3.63 μg/kg，超标率为4.64%，居民平均AFB1膳食暴露量为1.67 ng/(kg·d)，平均暴露限值(MOE)为240；男性居民平均AFB1膳食暴露量低于女性居民，城市居民低于农村居民，AFB1对女性居民造成的风险高于男性居民，对农村居民造成的风险高于城市居民。风险评估结果表明，梧州市居民通过土榨花生油摄入AFB1潜在风险较高。 In order to understand the dietary exposure risk of aflatoxin B1 (AFB1)of Wuzhou residents through native pressed peanut oil from small workshops,a total of 496 batches of native pressed peanut oils in three districts and four counties of Wuzhou city were randomly selected and tested the AFB1 content, and the point assessment method was applied to assess the dietary exposure risk of Wuzhou residents to AFB1 in native pressed peanut oil. The results showed that the detection rate of AFB1 in 496 batches of native pressed peanut oil was 40.3%, and the content ranged from 0.12 μg/kg to 109.00 μg/kg, with an average content of 3.63 μg/kg and an exceedance rate of 4.64%, and the average dietary exposure of AFB1 was 1.67 ng/(kg·d), with a mean margin of exposure(MOE) of 240. The average dietary exposure of AFB1 was found to be lower among male residents than female residents, and lower among urban residents than rural residents, while the risk of AFB1 was found to be higher among female residents than male residents, and higher among rural residents than urban residents. The risk assessment results indicate that the potential risk of AFB1 intake by Wuzhou residents through native pressed peanut oil is high.
