Determination of ochratoxin A in beer

Abstract

Ochratoxin A is a very common mycotoxin which can be found rather often, predominantly in various cereal materials and in products from this type of plants. Our aim was to apply an analytical procedure with a suitable detection level of ochratoxin A for its estimation in beer. The detection level of the method suggested was close to 0.001 µg/kg. The analytical procedure is based on HPLC separation with fluorescence detection. The application of this method is demonstrated and analytical results obtained with beer of domestic provenience are reported.
