A method was established for the simultaneous determination of 3-chloropropanol esters(3-MCPDE) and glycidol esters(GE) in different types of oil and lipid food products by gas chromatography-mass spectrometry(GC-MS).Optimizations on extraction, transesterification, derivatization and the chromatographic conditions of GC-MS of samples were completed. Limits of quantitation(LOQs) of the method for four types of food products,i.e. vegetable oils, milk powder, fried and puffed foods and bakery foods, were 100,25,125,20μg/kg, respectively, the total mean recoveries were in the range of 81.2%-109% with the relative standard deviations(RSD，n=6) of 0.77%-7.3% and the correlation coefficients(r) higher than 0.999.Moreover,the 3-MCPDE and GE contents in 30 oil and lipid food products were determined to be in the range of no detected-8.04mg/kg.The developed method could meet the demand for routine food inspection, in particular for the quantitative and qualitative determination of 3-MCPDE and GE in oil and lipid foods with its high efficiency, high sensitivity and strong workability.
