2013年内蒙古地区市售植物油中3种邻苯二甲酸酯含量调查分析
目的 了解2013年内蒙古地区市售植物油中邻苯二甲酸酯类物质的污染情况, 为加强食品安全监督管理提供依据。方法 在内蒙古地区各大型超市、农贸市场和食品商店等流通领域抽取不同品牌的桶装植物油共150份。采用固相萃取-气相色谱-质谱法测定了植物油样本中3种邻苯二甲酸酯类化合物(邻苯二甲酸二异壬酯、邻苯二甲酸二正丁酯、邻苯二甲酸(2-乙基已基)酯)的浓度。结果 在采集的150份样品中, 共有46份样品检测出邻苯二甲酸酯类物质邻苯二甲酸二正丁酯与邻苯二甲酸(2-乙基已基)酯, 总检出率为30.67%; 分别为18.67%和20.00%, 最高检出浓度分别为46.50 mg/kg和0.85 mg/kg; 邻苯二甲酸二正丁酯检出超标样品15份, 超标率为10.00%, 检出率和超标率最高的均是亚麻籽油, 检出率为38.89%, 超标率为19.44%。结论 内蒙古地区市售植物油中邻苯二甲酸酯类物质的检出率较高, 且邻苯二甲酸二正丁酯有超标样品检出。应加强植物油生产过程的监管及食品包装材料对植物油的污染, 定期开展监测工作。
Objective To understand the pollution situation of phthalates esters (PAEs) in commercially available vegetable oils in Inner Mongolia area in 2013, so as to provide basis for strengthening food safety supervision and management. Methods A total of 150 samples of vegetable oils with different brands were collected from several commodity circulation areas. The concentrations of 3 kinds of PAEs were determined by solid phase extraction-gas chromatography-mass spectrometry (SPE-GC-MS). Results Totally 46 positive samples of vegetable oils were detected with the detection rate of 30.67%. The detection rates of dibutyl phthalate (DBP) and bis(2- ethylhexyl) phthalate (DEHP) were 18.67% and 20.00%, respectively. The maximum concentrations of DBP and DEHP were 46.50 and 0.85 mg/kg, respectively. Besides, 15 excess samples of vegetable oils were detected, with the exceeding rate of DBP was 10.00%, and the maximum detection rate and exceeding rate of DBP in flaxseed oil were 38.89% and 19.44%, respectively. Conclusion There are high detection rates of DBP and DEHP in commercially available vegetable oils in Inner Mongolia area, and the exceeding rate of DBP are detected. Therefore, more attentions should be paid to strengthen the supervision of the production process of vegetable oils and the potential pollution in vegetable oils from packaging materials, and regular monitoring work should be carried.
