Abstract

The present invention provides a composition and method for treating edible glyceride oils to remove contaminants thereform. The composition can be added directly to crude oil, degummed oil, or used oil to reduce fatty acids, color bodies, trace metals, and other impurities. The composition comprises solid alkali metal silicate, particularly sodium metasilicate pentahydrate and hydrous sodium polysilicate. This material is added to oil in an amount approximately equal to the amount of free fatty acids present in the oil. The oil may then be heated and agitated. The oil is then filtered or centrifuged to remove the solid hydrous sodium silicate.
