This part of ISO 18363 describes 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 part of ISO 18363 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.
