北京市昌平区市售乳及乳制品中邻苯二甲酸酯类物质的调查分析
目的 了解北京市昌平区市售乳及乳制品中邻苯二甲酸酯(phthalates esters, PAEs)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 2014~2015年期间, 在昌平区各商场、超市、零售店、批发市场等流通领域抽取国内外不同品牌的乳及乳制品共220件。利用固相萃取-气相色谱-质谱法(gas chromatography-mass spectrometry, GC-MS)测定16种邻苯二甲酸酯类化合物浓度。结果 采集的220件样品中, 共有206件样品检测出邻苯二甲酸酯类物质, 总检出率为93.64%; 其中邻苯二甲酸二异丁酯(diisobutyl phthalate, DIBP)、邻苯二甲酸二正丁酯(dibutyl phthalate, DBP)、邻苯二甲酸(2-乙基已基)酯(bis(2-ethylhexyl) phthalate, DEHP)和邻苯二甲酸丁基苄酯(butyl benzyl phthalate, BBP)的检出率分别为91.82%、91.82%、6.82%和1.82%, 4类PAEs的最高检出浓度分别为0.085、0.287、0.204、0.151 μg/g。结论 在2014~2015年期间, 昌平区市售乳及乳制品中PAEs检出率较高, 应重视食品包装材料对食品的污染, 定期开展监测工作。
Objective To understand the pollution situation of phthalates esters (PAEs) in commercially available milk and dairy products in Changping district of Beijing, so as to provide basis for strengthening food safety supervision and management. Methods Two hundred and twenty samples of milk and dairy products with different brands were collected from several commodity circulation areas in 2014~2015. The concentrations of 16 kinds of PAEs were determined by solid phase extraction-gas chromatography-mass spectrometry (SPE-GC-MS). Results Two hundred and six positive milk and dairy samples were detected, with the detection rate of 93.64%. The detection rates of diisobutyl phthalate (DIBP), dibutyl phthalate (DBP), bis(2-ethylhexyl) phthalate (DEHP) and butyl benzyl phthalate (BBP) were 91.82%, 91.82%, 6.82% and 1.82%, respectively. Besides, the maximum concentrations of DIBP, DBP, DEHP and BBP were 0.085, 0.287, 0.204 and 0.151 μg/g, respectively. Conclusion There are high detection rates of PAEs in commercially available milk and dairy products in Changping district in 2014~2015. We should pay attention to the potential pollution in milk and dairy products from packaging materials, and carry out regular monitoring work.
