  • Publication number: 20100041850
    Abstract: A composition comprising a highly esterified polyol polyester wherein the polyester comprises a polyol residue and a plurality of fatty acids esters, and wherein from about 5% to about 80% of the fatty acid esters contains two or more pairs of conjugated double bonds.
    Type: Application

  • Publication number: 20100041849
    Abstract: A composition comprising a highly esterified polyol polyester wherein the polyester comprises a polyol residue and a plurality of fatty acids esters, and wherein from about 5% to about 80% of the fatty acid esters contains exactly one pair of conjugated double bonds.

  • Publication number: 20090192060
    Abstract: A method is provided for reducing friction between at least two metal surfaces which are in a frictional relationship with each other or otherwise in need of lubrication. The method includes contacting the metal surfaces with an effective amount of a lubricant composition comprised of partially-esterified sucrose molecules having, in one embodiment, an average distribution of from 5 to 7 fatty acids bound to a sucrose backbone. The lubricant may also include from about 20 ppm to about 10,000 ppm of an antioxidant, about half of which may be an active tocopherol.

  • Publication number: 20020016317
    Abstract: Sterol ester compositions having fatty acid moieties comprising greater than 50% monounsaturated fatty acids (MUFAs), preferably from about 55% to about 80% MUFAs, and more preferably from about 60% to about 75% MUFAs. Preferably, the fatty acid moieties comprise less than about 6% saturated fatty acids (SFAs), more preferably from about 0.1% to about 4% SFAs, and most preferably from about 0.5% to about 2% SFAs. The fatty acid moieties of the sterol ester compositions comprise 50% or less polyunsaturated fatty acids (PUFAs). Also disclosed are methods for preparing the sterol ester compositions and the products comprising them.

  • Patent number: 6080853
    Abstract: Polyol polyesters useful as nondigestible fat substitutes are prepared by improved heterogeneous interesterification processes between fatty acid esters of easily removable alcohol and polyol wherein the particle size of the polyol is reduced to less than 100 microns, and when the degree esterification of the polyol is between about 15% and no more than 75% substantially all of the unreacted polyol is removed. In the initial or early stages of the reaction, reaction conditions are adjusted to maintain a sufficient level of lower partial fatty acids to act as an emulsifier. The initial catalyst level is from about 0.001 to about 0.5 catalyst per mole of catalyst.
