Objective To establish quantitative analysis method of bisphenol A migrated from polycarbonate ( PC) products to food based on its migration behavior in dissolution media of water, 65% ethanol or 4% acetic acid, as influenced by temperature changes. Methods The solvent extraction method was employed to extract bpa migrated into the dissolution medium, and GC-MS was used to determine the migration amount. Results The GC-MS method established was sensitive with satisfying precision in the test curve range of 0. 05 ~ 200 mg / L ( r = 0. 9997) with a detection limit of 0. 02 mg / L. The detectable quantity of BPA in the dissolution medium reduced in the order of 65% ethanol, water and 4% acetic acid. Conclusion Migration of BPA increased in the same dissolution medium as the temperature increased, and its migration to the dissolution medium of water and ethanol was significantly higher than that of acetic acid.
