Solvent extraction of aflatoxins from contaminated agricultural products

and Summary Solvent extraction of agricultural products has been suggested as an effective means of removing aflatoxins from mold‐damaged commodities. The use of various polar solvents such as the azeotrope of acetone‐hexane‐water and of 2‐propanol‐water, aqueous acetone, and aqueous ethanol has been reported in the literature. This paper examines the overall aspects of solvent extraction, in particular the use of the azeotrope of 2‐propanol‐water, to remove aflatoxins from prepress solvent extracted cottonseed meal.
