Abstract:
Acrylamide (AA), which is toxic and probably carcinogenic for humans, can be
formed from food products containing carbohydrates and asparagine during high-temperature
cooking. The objective of this work was to study bromination and xanthydrol reactions for
derivatization of AA. The first method was based on derivatization of AA with potassium
bromide to 2,3-dibromopropionamide (2,3-DBPA) under an acidic condition. 2,3-DBPA was
then converted to 2-bromopropenamide (2-BPA) by dehydrobromination with triethylamine
for more stable derivative prior to inject to gas chromatography coupled with flame
ionization detector (GC-FID). For xanthydrol derivatization, AA was derivatized with
xanthydrol to xanthyl-AA under an acidic condition with heating for 20 minutes. The solution
was extracted by ethyl acetate and analyzed by GC-FID. The effects of some physical and
chemical parameters on sensitivity of both methods have been studied such as reaction time,
reaction temperature, extraction solvent and extraction time. Under the optimum conditions,
the calibration curves (R2 < 0.99) and less than 3% relative standard deviation (%RSD) were
obtained from both derivatization methods. Furthermore, the sensitivity of xanthydrol
derivatization is higher than bromination method. However, an additional preconcentration
step will be further employed and developed for improving the analytical performance.
