Abstract: A method for the determination of acrylamide in food by gas chromatography was studied.The method consistedof extraction, bromization, evaporation and GC analysis. The GC analysis was carried out by using Elite-Wax capillary columnand electron capture detector. The linear range was 0~2000μg/kg and the limit of detection was 3μg/kg. The relative standarddeviation was 3.97%~7.48% and the recovery rate was 69.9%. The method has good stability and sensibility.
