Abstract
Abstract A method for treating edible oils containing fatty acid to render the edible oils more suitable for preparation of foods which contemplates the treating of the edible oils with a molecular sieve to remove a sufficient amount of the fatty acids present. Molecular sieve is also used to upgrade the quality of inedible tallows and inedible oils by reducing their free-fatty-acid content and by reducing the darkness of color of the tallow.
