Rapid and sensitive method for the determination of four EU marker polycyclic aromatic hydrocarbons in cereal-based foods using isotopedilution GC/MS

A rapid and sensitive method has been developed for the determination of the four EU marker polycyclic aromatic hydrocarbons (PAHs) in some cereal based foods. The method is based on pressurized liquid extraction (PLE), solid phase extraction clean-up (SPE) and isotope dilution gas chromatography with mass-spectrometric detection (GC/MS). The developed method was calibrated for the content range of 0.1 µg/kg to 12.5 µg/kg. Recoveries of PAH were monitored in each sample via the recovery of 13C-labelled PAHs. Recovery values were in the range between 86 % and 91 %, with relative standard deviations (RSDs) between 5 % and 9 %. The achieved limits of detection were for all analytes below 0.05 µg/kg. The applicability of the method for the analysis of routine samples was studied by the analysis of a set of commercial bread and cornflakes samples. The developed method was found suitable for the determination of PAHs in cereal based foods like cornflakes and breads with total relative fat contents below 3.5%.
