食用植物油中黄曲霉毒素B1调查分析

调查了浙江省食用植物油中黄曲霉毒素B_1(AFB_1)的污染情况。根据浙江省食用植物油生产消费的实际情况,2016年9—12月,采用统计学方法采集151家食用植物油经销企业的花生油、玉米油、大豆油、菜籽油、油茶籽油、葵花籽油、芝麻油、调和油8大类散装油和定型包装油,共1 208个样品,高效液相色谱法测定AFB_1含量。结果表明:22个样品检出AFB_1,检出率为1.8%,超标率为0.0%;其中花生油、葵花籽油、玉米油和调和油检出AFB_1,浙江省特产的油茶籽油和菜籽油未检出AFB_1,散装油中AFB_1检出率(3.8%)是定型包装油(0.9%)的4.22倍,食用植物油样品中AFB_1含量均低于国家限量标准。

Investigation and analysis of aflatoxin B1 in edible vegetable oil

The contamination status of aflatoxin B₁ (AFB₁ ) in edible vegetable oil in Zhejiang province was investigated. The contents of AFB₁ in 1 208 samples of peanut oil, corn oil, soybean oil, rapeseed oil, oil-tea camellia seed oil, sunflower seed oil, sesame oil and blend oil from 151 edible vegetable oil distribution enterprises in Zhejiang province from Sep 2016 to Dec 2016 were determined by HPLC. The results showed that AFB₁ was detected from 22 samples, and the detection rate of AFB₁ was 1.8%. None of the samples exceeded the maximum level. AFB₁ was found in peanut oil, sunflower seed oil, corn oil and blend oil. AFB₁ was not found in oil-tea camellia seed oil and rapeseed oil of Zhejiang special products. The AFB1 detection rate of bulk oil (3.8%) was obviously higher than that of stereotyped packaging products (0.9%). The AFB₁ contents in edible vegetable oil samples were lower than the limitation of national standard.
