Vile smelling oils, and particularly fish oils, are purified by first subjecting the oil to a steam stripping operation under vacuum and in the presence of a small proportion of organic solvent, such as an aliphatic hydrocarbon solvent in an amount of from 2 to about 10 percent, so as to remove volatile amines together with wax and wax ester components. The stripped oil is then purified to remove malodorous components by subjecting the same to adsorption with a quaternary ammonium-acidic clay adduct.
