Process for removing soaps and fatty acids from sucrose fatty acid esters

摘要

A process for removing alkali metal soaps and fatty acids included as impurities in sucrose fatty acid esters by mixing an organic solvent solution of sucrose fatty acid esters with an alkaline earth metal compound selected from the group consisting of calcium and magnesium oxides, calcium and magnesium hydroxides and magnesium carbonate, thereby precipitating the soaps and the fatty acids as calcium or magnesium metal soaps, and separating the resulting precipitate.
