| Zusammenfassung: | The present invention provides a method for the direct esterification of stanols and sterols with catalyst, which can be acidic or basic, in the presence of a color deactivating agent to form stanol/sterol-esters. The method provides a synthetic route that is amenable to large scale production of the esters in high yields. A preferred embodiment employs a food grade process free of organic solvents or mineral acids. |
