The migration rules of acrylate monomers in plastic food contact materials were studied in this work. The migration rules of two acrylate monomers from food packing materials to four different stimulants including pure water, 4% acetic acid, 10% ethanol and isooctane were investigated by supercritical fluid chromatography (SFC) technology. The effects of food simulation species, concentration of ethanol, migration time and migration temperature on the migration amount of acrylate monomers were studied. The results showed that the migration of acrylate monomers in different food simulants were in the order: 10% ethanol>4% acetic acid>isooctane>water. Moreover, acrylate monomers were more likely to migrate in high concentration of ethanol. In the same food simulation, the migration of acrylate monomers increased with the increase of temperature and time. This study can provide theoretical basis and technical support for food safety control in the process of production, storage and transportation.
