    Compounds included in the inner coating of canned coffee were analyzed with liquid chromatography/mass spectrometry. The mass spectrometer was a hybrid quadrupole and time-of-flight type and run data-dependent acquisition mode that acquired fragment ions for features with sufficient abundance. Interpretation of the data revealed the adsorption of food-derived compounds in the inner coating, as well as byproducts and additives of polymer. In addition to the presence of ethylene terephthalate cyclic oligomers, the presence of antioxidants such as 2,2′-methylenebis[6-(1-methylcyclohexyl)-p-cresol] was confirmed. The finding can be valuable for feature health risk assessment of food contact materials.
