title: Determination of less polar heterocyclic aromatic amines in standardised beef extracts and cooked meat consumed in Austria by liquid chromatography and fluorescence detection.
abstract: An analysis method was developed for the determination of trace levels of less polar heterocyclic aromatic amines (HAs) in food samples. The development started from a frequently used sample pre-treatment scheme which was slightly improved to make it applicable with high-performance liquid chromatography (HPLC) with fluorescence detection. The method was applied for the analysis of a standardised beef extract containing 5-15 ng/g of HAs and the results are compared with those of the other participants in the same European project. In addition, the method was used for the analysis of less polar HAs in cooked meat consumed in Austria.
