A B S T R A C T The invention relates to a process for purifying crude products containing esters of a non-reducing sugar like sucrose, and one or more fatty acids such as palmitic acid, stearic acid etc. by subjecting said crude esterification products to an extraction treatment with supercritical carbon dioxide. After carrying out this extraction treatment a residue comprising the fatty acid esters of non-reducing sugars, the unreacted sugar and the salts as well as an extract comprising the fatty acids, fatty acid alkyl esters and also any solvents, if present, are obtained. The unreacted sugar and salts, present in the obtained residue, can be removed from said residue by, for example, a washing operation resulting in a final product of pure esters of the non-reducing sugar and one or more fatty acids. This last removal step concerning the unreacted sugar and salts may also be carried out before the application of the above indicated extraction treatment with supercritical carbon dioxide.
