Objective The method was developed for the determination of the migration of methyl methacrylate (MMA) in sunflower oil simulants. Methods MMA was extracted with ethanol under vortex assisted ex-traction for 2 minutes and analyzed by gas chromatography-mass spectrometry(GC-MS).The external standard method was used for quantization. Results The quantification limit (LOQ) of MMA was 0.75 mg/kg. The calibration curve was linear within 0.75~30.00 mg/kg with 0.9998 as a typical correlation coefficient. The recoveries ranged from 86.71%~100.45%, and the relative standard deviation were less than 5% (n=6). Conclusion The sensitivity , recovery and selectivity of the method could meet the requirements of practical work.
