This document specifies a 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 acid catalysed ester cleavage and derivatization of cleaved (free) analytes with phenylboronic acid？(PBA) prior to GC/MS analysis.

This document is applicable to solid and liquid fats and oils. For all three analytes the limit of quantification (LOQ) is 0,1？mg/kg and the limit of detection (LOD) is 0,03？mg/kg.
