  • The certification of the mass fractions of pyrene chrysene, benzo[k]fluoranthene, benzo[a]pyrene, benzo[ghi]perylene and indeno [1,2,3-cd]pyrene in two coconut oil reference materials (CRM 458 and CRM 459)


This report describes the preparation of two coconut oil reference materials and the certification of six selected polycyclic aromatic hydrocarbon (PAH) mass fractions. Details are given in this report on the preparation process and the investigations to verify homogeneity and stability of the materials. The certification exercise was carried out by 13 laboratories using a variety of extraction and clean-up procedures and different end-determination steps. These coconut oil reference materials are representative for the whole range of edible oils and fats since all these types of oils have similar chemical composition of about 97% triglycerides. Edible oils are different due to the type of the fatty acids and their profile.
