Acrylamide in Caribbean foods - Residual levels and their relation to reducing sugar and asparagine content

摘要

The acrylamide levels in commercial and homemade Caribbean foods were determined by pre-derivatisation of acrylamide to 2-bromopropenamide and analysed by gas chromatography with mass spectrametric (GC/MS) detection. Over 100 Caribbean food samples were analysed for the presence of acrylamide. These samples include: biscuits, breakfast cereals, banana chips and home-prepared foods: breadfruit; Artocarpus altilis, banana fritters, and dumplings. The limit of detection (LOD) for the GC/ MS method was found to be dependent on the type of column used for the GC/MS analysis. The DB1701 and the DB-VRX columns gave LODs of 20 and 4 μg/kg, respectively. Acrylamide has not been found in raw foods or foods which have been cooked by boiling. Its content in all other foods had concentrations in the range, 65-3640 μg/kg. The relationship between acrylamide levels and precursor concentration as well as the health implications of our findings are discussed.
