摘要

A process for removing chlorophyll color impurities from vegetable oils, the process comprises: i) dispersing a source of phosphoric acid in vegetable oil to form a mixture having a moisture content of less than 0.1% by weight which mixture is maintained at a temperature in the range of 70.degree.C to 160.degree.C until a precipitate containing chlorophyll color impurities is formed; and ii) at any time thereafter during conventional oil processing up to and including the removal of bleaching clay from the oil, separating the precipitated material from the oil to remove the chlorophyll color impurities with the precipitated material.
