Abstract
Fatty acid esters, particularly those suitable for use in foods and cosmetics, are decolored by passing a solution of a fatty acid ester dissolved in an apolar solvent through particulate montmorillonite which is in admixture with particulate silica gel and/or active carbon. The solution passed through the column is obtained and the solvent is eliminated from the ester.
