The qualitative and quantitative analysis of aflatoxin B(1) in a model system (water/ethanol), in different wines and in beer using one- and two-photon-induced fluorescence is discussed. The absorption and fluorescence properties of aflatoxin B(1) depend on the solvent and pH. The two-photon-absorption cross-section was calculated for aflatoxin B(1) in beer and wine (sigma (2) approximately 25 GM) for excitation at 720 nm. A comparison of the one- and two-photon- induced fluorescence results… CONTINUE READING
