Abstract

A new direct GC-MS method for quantitative determination of acrylamide in several foods is described. The useof diatomaceous earth as sorbent in combination with ethyl acetate as desorbing solvent appeared to be a very effectiveclean-up step for the aqueous extracts. This allowed us to make use of a mass selective detector (MSD), which is cheaper,and available in more laboratories, than tandem mass spectrometers. Use of the MSD in selected ion monitoring (SIM)mode resulted in a LOQ level of 3 μg/kg for acrylamide in different food samples. The calibration graph was linear overmore than 3 decades.
