REF. 01-7756 PATENT ABSTRACT OF THE DISCLOSURE Adsorbents are provided which are suitable for use in the removal of contaminants selected from the group consisting of free fatty acids, soaps, phosphorus, metal ions and color bodies. The adsorbents comprise inorganic porous supports selected from the group consisting of substantially amorphous alumina, diatomaceous earth, clays, magnesium silicates, aluminum silicates and amorphous silica, treated with a base in such a manner that at least a portion of said base is retained in at least some of the pores of the support to yield base-treated inorganic porous adsorbents. Processes for removing free fatty acids, etc., from glyceride oils using these adsorbents are also provided.
