The aim of this work was to select and identify the best markers of aromatic hydrocarbon mineral oil (MOAH) in food packaging. For this purpose a series of mineral oils was initially analyzed. Polycyclic Aromatic Hydrocarbons (PAHs) and the alkylated isomers of Methylnaphthalene (MNS), Diisopropylnaphtalene (DIPNs), Dibenzothiophenes (DBTS), Methyldibenzothiophene (MDBTs), Dimethyldibenzothiophenes (DMDBTs) and Benzonaphthiophenes (BNTS) were then explored. Their presence was confirmed by direct analysis of several mineral oils by Atmospheric Solids Analysis Probe Quadrupole-Time of Flight Mass Spectrometry (ASAP-QTOF-MS). Atmospheric Pressure Gas Chromatography Quadrupole-Time of Flight Mass Spectrometry (APGC-QTOF-MS) was used to confirm the markers in different samples of oils, rPET, recycled cardboard and packaging of couscous and semolina to confirm the contamination. 27 markers were found in the mineral oil samples, 22 of them in rPET, 8 in recycled board and no MOAH were found in packaging of couscous and semolina.

这项工作的目的是选择和识别食品包装中芳烃矿物油（MOAH）的最佳标记。为此，首先分析了一系列矿物油。然后研究了多环芳烃（PAHs）和甲基萘（MNS），二异丙基萘（DIPNs），二苯并噻吩（DBTS），甲基二苯并噻吩（MDBTs），二甲基二苯并噻吩（DMDBTs）和苯并噻吩（BNTS）的烷基化异构体。通过大气固体分析探针四极杆飞行时间质谱（ASAP-QTOF-MS）对几种矿物油进行直接分析，证实了它们的存在。大气压气相色谱四极杆飞行时间质谱（APGC-QTOF-MS）用于确认不同油品，rPET，回收纸板以及蒸粗麦粉和粗面粉的包装以确认污染。在矿物油样品中发现了27种标记，在rPET中发现了22种标记，在回收纸板中发现了8种标记，在蒸粗麦粉和粗面粉的包装中未发现MOAH。
