摘要

The migration rule of bisphenol-A-related compounds from can coatings into canned food and oil-based simulant was explored, and the quantification and confirmation of these compounds were performed with an ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS). The correlation between the molecular weight, migration time, the initial concentration and the migration level of contaminants was investigated. A quantitative structure-property relationship (QSPR) model of migration was established corresponding to the migration of these migrants in the oily simulant at 55 degrees C, which served as an accelerated shelf life testing (ASLT) with the use of elevated temperature to simulate long-term storage at room temperature. The correlation coefficient (R), leave-one-out cross-validation coefficient (R LOO) and external validation coefficient (Q ext) for the established model were all above 0.9000. What is more, application of the developed model was tentatively validated with three oily canned foods, whose results showed that the model can play an important role in providing a reference for the estimation of migration behavior of bisphenol-A-related compounds in canned food.
