摘要： An UHPLC-QTOF/MS method was employed to identify polyester oligomers in a laminated steel food can. Over 15 oligomers originated from polyethylene terephthalate (PET) were identified with either a cyclic or a linear structure. Migration experiments were conducted by filling the cans with various food simulants (isooctane; 50 % ethanol; 50 % ethanol with 2 % NaCl, 5 g/L citric acid, or both), followed by sterilization at 121 °C for 30 min and storage at 60 °C for 10 days. Migration levels of PET oligomers were recorded by UHPLC-QTOF/MS as a function of time. The results indicated that sterilization (high temperature and pressure) greatly promoted the migration of most PET oligomers, with over 50 % migrating into isooctane and over 70 % into 50 % ethanol after sterilization. The migration level varied among the PET oligomers, depending on their initial content in the polymer and solubility in the food simulant. Higher migration occurred in 50 % ethanol than in isooctane, and the presence of citric acid in 50 % ethanol further enhanced migration. A threshold of toxicological concern (TTC) assessment revealed that the migration of most cyclic PET oligomers into 50 % ethanol exceeded the TTC-derived threshold, which may present a safety concern.
