植物油中邻苯二甲酸酯来源和检测方法研究进展

Research advances in sources and detection of phthalates in vegetable oil

旨在为植物油中塑化剂的污染防控提供参考,对邻苯二甲酸酯(PAEs)种类和性质,植物油中PAEs的来源以及植物油中PAEs的检测方法进行了综述。PAEs是脂溶性物质,易迁移到植物油中。植物油中PAEs的来源主要有植物油原料、植物油加工过程以及植物油包装材料。测定植物油中PAEs的前处理方法有液液萃取法、凝胶渗透色谱法、固相萃取法、分散固相萃取法、固相微萃取法,常用的植物油PAEs检测方法有气相色谱法、气相色谱-质谱联用法、高效液相色谱法以及液相色谱-质谱联用法。PAEs是植物油的风险因素之一,建立植物油中PAEs快速、便捷、重现性好的检测方法对于实现植物油中PAEs的实时监控具有重要意义。

In order to provide reference for the prevention and control of plasticizers in vegetable oil,the types,properties,sources and detection methods of phthalates(PAEs)in vegetable oil were reviewed.PAEs are a class of fat-soluble substances and easily migrate into vegetable oil.The main sources of PAEs in vegetable oil include raw materials,processing process,and packaging materials.The pretreatment methods for the determination of PAEs in vegetable oil include liquid-liquid extraction,gel permeation chromatography,solid-phase extraction,dispersed solid-phase extraction,solid-phase microextraction.The common detection methods for PAEs in vegetable oil include gas chromatography,gas chromatography-mass spectrometry,high-performance liquid chromatography and liquid chromatography-mass spectrometry.PAEs are one of the risk factors in vegetable oil,and establishing a rapid,convenient,and reproducible detection method for PAEs in vegetable oil is of great significance for the real time monitoring of PAEs in vegetable oil.
