Abstract :
[en] Mineral oil hydrocarbons (MOHs) derives from crude petroleum through distillation processes and various refining steps. It contains saturated hydrocarbons (MOSH) and aromatic hydrocarbons (MOAH). MOHs as food contaminant has received attention due to its possible negative effects on human health [1], as stressed in the Opinion published in 2012 by the European Food Safety Authority (EFSA) (Panel on Contaminants in the Food Chain), pinpointing particularly towards MOAH with three or more, non- or simple alkylated aromatic rings as the main potential concern” [2]. The routine analytical method to determine the amount of MOHs in food uses hyphenated high-performance liquid chromatography - gas chromatography with a flame ionization detector (HPLC-GC/FID) [3]. A disadvantage of this method is that it gives no conclusive information about the type of substances present in the contamination and does not enable the separation of either different MOAH sub-classes or MOSH from MOSH- Analogs. Comprehensive two-dimensional GC combined with time-of-flight mass spectrometry (GC×GC-TOFMS) allows a separation of the different sub-classes, nevertheless the MS cannot provide any quantitative information. Therefore, parallel detection in combination with an FID detector, has been developed for the characterization and quantification of MOHs in food. However, to be able to translate the information acquired by the TOFMS detector to the quantification process in FID, a fine tune of the chromatographic conditions is needed in order to obtain comparable 2D plots to compensate the different outlet pressure (vacuum for MS and atmospheric pressure for FID). At the same time, a suitable software for quantification of selected regions in the FID contour plot is being developed, showing promising preliminary results [4].
