摘要

缩水甘油酯(GEs)和2-和3-一氯丙二醇酯(MCPDEs)是新出现的过程产生的食品污染物，被称为可能的致癌物。本文首次开发并验证了一种直接方法，该方法使用液相色谱-串联质谱法在单一序列中同时定量加工食品中的7种GEs和24种MCPDE同源物，无需酯裂解或衍生化，从而允许同时分析多种食品基质，具有高精度和精密度。我们的研究结果显示，GEs的水平从

Simultaneous determination of 24 congeners of 2- and 3-monochloropropanediol esters and 7 congeners of glycidyl esters using direct multi-residue analytical LC-MS/MS methods in various food matrices.

Glycidyl esters (GEs) and 2- and 3-monochloropropanediol esters (MCPDEs) are emerging process-generated food contaminants known as possible carcinogens. Herein, a direct method is developed and validated for the first time to simultaneously quantify seven GEs and twenty-four MCPDE congeners of processed foods using liquid chromatography-tandem mass spectrometry in a single sequence without ester cleavage or derivatisation, thereby allowing for the simultaneous analysis of numerous food matrices with high accuracy and precision. Our results show levels of GEs varying from
