高效液相色谱法同时测定食品塑料包装材料中8种邻苯二甲酸酯的含量

摘要/Abstract

摘要： 建立检测塑料包装材料中8种邻苯二甲酸酯类(PAEs)的高效液相色谱法，并采用所建立的方法分析了7种塑料材质、包装不同类型食品的27个塑料包装材料中的PAEs含量，结果发现所有抽检样品中均含有DBP，且44%的样品中含有DEHP，其中1个样品还含有BBP，其他的PAEs未被检出，说明我国目前食品塑料包装材料所用增塑剂主要以DBP和DEHP为主；DBP的含量范围为22.89～267.6mg/kg，而DEHP的含量范围为0.33～899.8mg/kg，其中PET和HDPE两种包装材料中含有很高量的DEHP。

Abstract: A high performance liquid chromatographic method for simultaneous determination of eight kinds of phthalic acid esters (PAEs) in plastic food packaging materials was developed. The contents of PAEs in 27 plastic packaging material samples, assigned to 7 classes were analyzed. All the samples contained DBP, and 44% of them contained DEHP, including one sample found to contain BBP and no other PAEs. These results illustrate that DBP and DEHP are dominantly used as plasticizers in plastic food packaging materials in China at present. The contents of DBP and DEHP were 22.89–267.6 mg/kg and 0.33–899.8 mg/kg in 27 plastic packaging material samples, respectively. PET packaging material and HDPE packaging material were both richer in DEHP.

Key words: high performance liquid chromatography, food plastic packing material, phthalic acid esters
