  • Preparation of sterol and stanol-esters
    Patent number: 6635774
    Abstract: The present invention provides a method for the direct esterification of stanols and sterols with fatty acids 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, does not produce or use non-food grade products and is substantially free of the use of a catalyst.
    Type: Grant
    Filed: May 6, 2002
    Date of Patent: October 21, 2003
    Assignee: McNeil-PPC, Inc.
    Inventors: Allan Roden, James L. Williams, Ruey Bruce, Frank Detrano, Marie H. Boyer

  • Preparation of sterol and stanol-esters
    Patent number: 6184397
    Abstract: 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.
