Abstract
The polarographic behaviour of aflatoxins B1, B2, G1, and G2 has been investigated and found to parallel closely that of coumarin and its derivatives. Differential-pulse polarography has been applied to the determination of aflatoxin B1 in a variety of food products. Good agreement was obtained between the differential-pulse polarographic method and visual comparison of the fluorescence exhibited by the aflatoxin following thin-layer chromatographic separation. Electroactive interferences co-extracted from high lipid-containing foods were removed by separation on a Sephadex LH-20 column.Keywords
