This part of ISO 18363 describes 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. This method is applicable to solid and liquid fats and oils. This part of ISO 18363 can also apply to animal fats and used frying oils and fats, but a validation study must be undertaken before the analysis of these matrices. Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this international standard.
