During processing of foodstuffs or foodstuff ingredients, process contaminants can form in processes including fermenting, smoking, drying, refining and heating at high temperatures. Well-known process contaminants include polycyclic aromatic hydrocarbons (PAHs), free 2- and 3-monochloropropanediols (MCPDs) or MCPDs esterified with various fatty acids, glycidyl fatty acid esters (GE), acrylamide and furans. As these can have a negative impact on human health, maximum levels have been defined in foodstuffs. Accordingly, we are dependent on a reliable analysis of these substances.
METAS has been appointed by the Federal Food Safety and Veterinary Office (FSVO) as the National Reference Laboratory for Process Contaminants in Foodstuffs.
For this substance class, we maintain a portfolio of analyses in the trace range. We perform the analysis mainly using gas and liquid chromatography coupled with mass spectrometry (GC- and LC-MS).
Validation of methods and suitability tests
In order to continue to offer our analytics at the highest level, we are taking part in the validation of methods studies and in the suitability tests organised by the EU reference laboratory.
If required, we will organise and mediate suitability tests for the cantonal laboratories.
