本文件规定了一种快速测定2-MCPD酯（结合2-MCPD）、3-MCPD酯（结合3-MCPD）和缩水甘油酯（结合缩水甘油）的方法，该方法基于GC-MS/MS分析之前的碱性催化酯裂解和裂解（游离）分析物与苯硼酸（PBA）的衍生化。通过添加同位素标记的酯结合3-MCPD，可以纠正缩水甘油酯高估，从而在操作过程中量化3-MCPD诱导的缩水甘油。

This document specifies a rapid procedure for the simultaneous determination of 2-MCPD esters (bound 2-MCPD), 3-MCPD esters (bound 3-MCPD) and glycidyl esters (bound glycidol) in a single assay, based on alkaline catalysed ester cleavage and derivatization of cleaved (free) analytes with phenylboronic acid (PBA) prior to GC-MS/MS analysis. Glycidyl ester overestimation is corrected by addition of an isotopic labelled ester bound 3-MCPD which allows the quantification of 3-MCPD induced glycidol during the procedure.
