摘 要：A gas chromatography mass spectrometry（GC-MS） method was developed for the simultaneous determination of 3-chloropropane-1,2-diol fatty acid esters（3-MCPDEs）, 2-chloropropane-1,3-diol fatty acid esters（2-MCPDEs）, 1,3-dichloro-2-propanol fatty acid esters（1,3-DCPEs） and 2,3-dichloro-1-propanol fatty acid esters（2,3-DCPEs） in refined corn oil. The analytes were extracted by solid-phase extraction and were eluted with ethyl acetate. The detection was performed by selected ion monitoring mode for the target compounds. The procedure showed good linearity and precision. The limit of detection and quantification were less than 0.03 ng/ml and 0.1 ng/ml, respectively. The recoveries of chloropropanol fatty acid esters were in the range of 98.6 % ～ 108.3 %. The method has been successfully applied to determine these compounds in refined corn oil.
