Abstract: An analytical method of cancerigenic acrylamide in food by GC-MS was studied in this article. The acrylamide in samples was extracted with polar solvents such as water,alcohols and cleaned up by centrifugal fitration,solid-phase-extraction- column. 2,3-DBPA was derived from the extracts through bromation,and determined by GC-MS.The major characteristic ion fragments (m/z) are: 152,150,108,106. The limit of detection is 5～10μg/kg. The recoveriy is 80.0%～110.0%. The variable coefficient is 3.25%～9.40%. The linear range is 0～3.5mg/kg. This method is precise and selective,low limit of detection,wide liner range,little interference. It is suitable for the determination of acrylamide in food.
