Determination of acrylamide in sugar by capillary GLC with alkali flame‐ionization detection

Abstract

A method for the determination of acrylamide traces as a residue of anti‐incrustation agents in sugar was developed. Acrylamide was extracted into ethyl acetate after derivatization by bromination to 2,3‐dibromopropionamide (2,3‐DBPA). The extract was cleaned up on a silica gel column and analysed by gas‐liquid chromatography with an alkali flame‐ionization detector (AFID). A glass capillary column with OV‐1 stationary phase was used for this analysis. The recovery of the method determined in model experiments was 70.0% and 77.1% at 100 μG kg⁻¹ and 20 μg kg⁻¹, respectively. The limit of detection of acrylamide in sugar is 1–10 μg kg⁻¹. Parameters of the described method are compared with other published methods.
