Phthalic acid esters (PAEs) may be used as plasticizer and softener for the manufacturing of plastic products, especially in polyvinyl chloride (PVC). The residue of PAEs in food may affect human health. The method of qualitative analysis and quantitative analysis of 15 PAEs are established by total ion chromatogram (TIC) and select ion monitor (SIM) of gas chromatography-mass spectrometry (GC/MS). Combined with the solid phase extraction (SPE) method, PAEs residue of some fatty food in plastic packaging was detected, with the assessment of PAEs residual be discussed. The correlation coefficient was higher than 0.99. The limit of quantity was 2.93 similar to 105.24 mu g/kg and the limits of detection (LOD) for PAEs had values from 0.97 mu g/kg to 34.73 mu g/kg. This method was used for quantification of traces of PAEs in fatty food. The results showed that 9 PAEs residual in fatty food were at the range of <50 similar to 1160 mu g/kg and detection rates were between 16.67 %(1:6)similar to 83.33 %(5:6). None of them was out of national standard.
