Monitoring of selected aflatoxins in brewing materials and beer by liquid chromatography/mass spectrometry

Popis výsledku v původním jazyce

In 2008?2011 a total set of 333 samples of brewing raw materials and beer were analyzed for the presence of aflatoxins B1, B2, G1 and G2. The standard analytical method using high-performance liquid chromatography coupled to mass spectrometric detectionwith immunoaffinity column clean-up was applied. The method was validated. Limits of detection varied from 0.04 to 0.12 ?g/kg in barley and malt, 0.08?0.58 ?g/kg in different hop samples, 0.04?0.12 ?g/kg in brewers? yeast and spent grains and 1.5?4.7 ng/l in beer. Limits of quantification varied from 0.13 to 0.39 ?g/kg in barley and malt, 0.25?1.94 ?g/kg in different hop samples, 0.13?0.39 ?g/kg in brewers? yeast and spent grains and 5.1?15.2 ng/l in beer. In 7 of 216 samples of brewing raw materials (3.2%), aflatoxins were found at trace concentrations to 1.2 ?g/kg. In 6 of 117 (5.1%) beer samples, aflatoxins were detected at concentrations to 31.0 ng/l. Values in barley and malt did not exceed the maximum allowable limit set by the Eu
