Abstract
A method for the removal of Aflatoxin from materials including cereals, oil seeds and feedstuffs contaminated therewith comprising contacting said materials with a mixed solvent system of liquid dimethyl ether and water. The water is employed in an amount of 2 to 8 % by weight with respect to the liquid dimethyl ether. Such method which can reduce the Aflatoxin content to 15 ppb or less, can be conducted at low temperatures so that no proteins contained therein are denaturated. Further, the spent solvent system containing Aflatoxin can be easily regenerated by contacting it with activated carbon and recycled.
