建立了一种固相萃取-气相色谱同时检测食用植物油中9种增塑剂和5种抗氧剂的分析方法，对方法进行了评价，并运用所建立的方法对14种食用植物油中增塑剂和抗氧剂残留量进行检测。结果表明，9种增塑剂和5种抗氧剂的方法最低检出限为0.024~0.087 mg/kg，在0.1~50 mg/L范围内具有良好线性关系（R2≥0.999 1）；在食品模拟液和食用植物油中添加回收率为76.90%~123.35%，相对标准偏差（RSD）为1.47%~8.85%，方法稳定可靠，能够满足食用植物油中多种增塑剂、抗氧剂的同时分析。选取的14种样品中检测到有部分增塑剂和抗氧剂的残留。
A method for simultaneous determination of 9 kinds of plasticizers and 5 kinds of antioxidants in edible vegetable oil by solid phase extraction (SPE) -gas chromatography (GC) was established and evaluated. The results showed that the limit of detection of the method was 0.024~0.087 mg/kg, and the correlation coefficient R2 ≥ 0.999 1 in the range of 0.1~50 mg/L. The recoveries in food simulation solution and edible vegetable oil were 76.90%~123.35%, and the relative standard deviation (RSD) was 1.47%~8.85%. This method is stable and reliable, and it can be used for simultaneous analysis of multiple plasticizers and antioxidants in edible vegetable oil. Besides, some plasticizers and antioxidants residues were detected in the selected 14 kinds of samples.
