Abstract
A method of producing industrial corn base oil from a raw corn oil byproduct of a corn ethanol production process. The raw corn oil byproduct of the corn ethanol production process is first washed to separate water-soluble products from raw corn oil, then the free fatty acid in the resulting corn oil is neutralized using potassium hydroxide, and a polymeric quaternary biocide is added in a demulsification step, followed by vacuum dehydration of the demulsified corn oil, degumming of the dehydrated corn oil using citric acid, removal of red color from the oil, and final polishing.
