A composition useful for the adsorptive bleaching of edible oils, particularly of vegetable oils, is disclosed. The composition consists essentially of a major portion of bleaching clay and a minor portion of an alumino-silicate zeolite preferably of the faujasite-type structure. The zeolite used has its base exchange sites occupied by alkaline earth metal and/or transition metal cations, wherein the transition metal cations employed exclude those of the Group VIII metals. Preferably, the zeolite is a calcium-, magnesium-, or lanthanum-exchanged Y-zeolite. The presence of the zeolite in the bleaching composition significantly improves the removal of free fatty acids from the oil while permitting simultaneous removal of color impurities.

Solid bleaching composition for edible oils

This invention relates to an improvement in the production of zeolites, particularly, zeolites of the faujasite type, employing clay based seeds derived from natural halloysite.
