An accurate and sensitive procedure is proposed for estimating aflatoxins in both alkaline and acidulated soapstocks. Sample suspensions in aqueous acetone are adjusted to pH 3 with hydrochloric acid, extracted in a high speed blender, treated with lead acetate and partitioned into chloroform. After silica gel cleanup, aflatoxins in purifie extracts are estimated by thin layer chromatography. The use of acetone and lead acetate together apparently catalyzes the relactonization of flatoxins B1nd G1and leads to essentially quantitative recovery of aflatoxin B1and somewhat lower recovery of G1added to alkaline or acidulated soapstock. |
