Aflatoxins in Foods and Feedstuffs. Part 3. Fluorodensitometric method for determination of aflatoxins M1 and M2 in presence of aflatoxins B1, B2, G1 and G21

Abstract The method of aflotoxins M 1 and M 2 determination in presence of aflatoxins B 1 , B 2 , G 1 and G 2 is presented. The fluorescence properties of aflatoxin M 1 and M 2 are discribed. A simple method of aflatoxin M extraction is proposed. Results of different tests for confirmation of aflatoxins M are discussed. During control of powdered milk from three factories aflatoxins M were not detected in final products.
