ISO 18363-3:2017 Animal and vegetable fats and oils - Determination of fatty-acid-bound chloropropanediols (MCPDs) and glycidol by GC/MS - Part 3: Method using acid transesterification and measurement for 2-MCPD, 3-MCPD and glycidol
standard by International Organization for Standardization, 12/01/2017

Full Description
ISO 18363-3:2017 specifies a procedure for the simultaneous determination of 2-MCPD esters (bound 2-MCPD), 3MCPD esters (bound 3MCPD) 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.
ISO 18363-3:2017 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.
