To investigate the contamination of benzo(a)pyrene in edible vegetable oil from Henan Province.
A total of 1190 edible vegetable oil samples from Henan Province were collected. The concentration of benzo(a)pyrene was examined by high performance liquid chromatography.
The concentration of benzo(a)pyrene in prepackaged edible vegetable oils was <0. 3-63. 5 μg/kg with an average of 1. 5 μg/kg. The detection rate of benzo(a)pyrene in samples was 80. 0%, and the over standard rate was 0. 6%. In terms of subclasses of vegetable oil, the sesame seed oil samples were most seriously contaminated with benzo(a)pyrene. The risk of the benzo(a)pyrene contamination of sesame seed oil produced by aqueous extraction method was higher than that by mechanical pressed method. The risk of benzo(a)pyrene contamination in sesame seed oil and rapeseed oil increased as the decrease of quality grade.
The result suggested that the sesame seed oil produced by aqueous extraction method had high risk in benzo(a)pyrene contamination in Henan Province.
调查河南省食用植物油中苯并（a）芘的污染情况。
共采集1190份河南省食用植物油样品。采用高效液相色谱法检测苯并（a）芘的含量。
预包装食用植物油中苯并（a）芘含量为<0.3 - 63.5μg/kg，平均含量为1.5μg/kg。样品中苯并（a）芘的检出率为80.0%，超标率为0.6%。就植物油亚类而言，芝麻油样品受苯并（a）芘污染最严重。水代法生产的芝麻油苯并（a）芘污染风险高于机械压榨法。芝麻油和菜籽油中苯并（a）芘污染风险随质量等级降低而增加。
结果表明，河南省水代法生产的芝麻油苯并（a）芘污染风险高。
