A new approach for the determination of acrylamide (AM) in foods by solid phase microextraction-gaschromatography (SPME-GC) was established. AM was bromized and transformed to 2-bromoacrylamide (2-BAM). 2-BAMwas then extracted by a commercial SPME fiber, 75-µm Car/PDMS fiber, for GC detection. The influence of extraction anddesorption parameters such as extraction temperature and time, stirring rate, desorption temperature, and time were studiedand optimized. The mass concentration was proportional to the peak area of 2-BPA from 1.0 to 8,000µg/L. The detectionlimit of the SPME-GC for 2-BAM was found to be 0.1µg/L, and the recoveries and relative standard deviations for differentfood samples were 74.5 to 102.0%, and 4.2 to 9.1%, respectively. The presented method was applied to the determination ofAM in fried foods.
