This document specifies a procedure for the simultaneous determination of 2-MCPD esters (bound 2-MCPD), 3\u2010MCPD esters (bound 3\u2010MCPD) 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.<\/p>\n

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.<\/p>\n
