  • Patent number: 5965179
    Abstract: To incorporate water into a chocolate, chocolate and an emulsion or dispersion of a thickening or gelling substance in water, particularly a dispersion of microcrystalline cellulose in water, are introduced into an extruder and mixed and passed to an extruder nozzle so that the chocolate mass extrudate from the nozzle has a temperature of from 0.degree. C. to 28.degree. C.

  • Patent number: 5897994
    Abstract: A mixture of fatty acids rich in polyunsaturated fatty acids is esterified by enzymatic catalysis and then the reaction mixture is saponified, which provides an organic phase containing esters and an aqueous phase which contains fatty acids, the phases are separated and the fatty acids of the aqueous phase are extracted by a non-polar solvent to obtain the fatty acids in the solvent, after which the solvent may be removed from the fatty acids.

  • Patent number: 5585130
    Abstract: Antioxidant principles are concentrated in a fat by mixing the fat with a vegetable material containing phenolic antioxidants to obtain a mixture and pressing the mixture under a pressure of at least 40 bar. The fat concentrated with antioxidant principles may be added to a fat-containing food to protect the food from oxidation.

    Assignee: Nestec S.A.
    Inventors: Robert Aeschbach, Hans-Juergen Wille
  • Patent number: 5525260
    Abstract: An oil containing a spice extract which has antioxidant activity is prepared by mixing a spice extract contained in a polar solvent with an oil, evaporating the polar solvent from the mixture, adding a non-polar solvent to the mixture, to dilute the mixture and to precipitate constituents of the mixture, and stirring to obtain a homogenized non-polar solvent/extract/oil mixture, separating precipitate from that mixture and then evaporating the non-polar solvent phase to obtain an oil containing spice extract. The oil containing the spice extract may be mixed with further polar solvent containing the spice extract, after which the process is repeated to enrich the final oil product with spice extract.

  • Patent number: 5492709
    Abstract: Antioxidant principles are concentrated in a fat by mixing the fat with a vegetable material containing phenolic antioxidants at an elevated temperature to obtain a mixture. The mixture is pressed under a pressure of at least 40 bar to obtain a fat concentrated with antioxidant principles, which may be added to a fat-containing food to protect the food from oxidation.

  • Patent number: 5401862
    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.

  • Patent number: 5318777
    Abstract: A sal fat fraction is obtained by dissolving sal fat in hexane at a temperature above 20.degree. C. and cooling the solution to 5.degree. C. to 12.degree. C. The cooled solution is seeded with 0.05% to 0.5% by weight sal stearin and then cooled to a temperature below -5.degree. C. A solid fraction is removed from the solution and hexane is removed from the liquid fraction to obtain a sal fat fraction which has a solid fat content at 20.degree. C. of 0% by weight and a solid fat content at 10.degree. C. below 4.5% by weight.

  • Patent number: 5243046
    Abstract: A mixture of fatty acids, including derivatives thereof, containing polyunsaturated fatty acids, including derivatives thereof, are reacted with urea in solution. The reaction medium is pumped through at least one scraped-surface heat exchanger for cooling the reaction medium for forming a dispersion of a solid inclusion complex and a liquid phase. The liquid phase which contains a fraction enriched with polyunsaturated fatty acids, including derivatives thereof, then is separated from the inclusion complex.

  • Patent number: 5130449
    Abstract: Substantially pure stearidonic acid is isolated from a mixture of polyunsaturated fatty acids by fractionating at 25% to 35% by weight solution of fatty acids by high-performance reverse-phase liquid chromatography using a mobile phase of 75% to 95% by weight methanol and 25% to 5% by weight water. The isolated stearidonic acid is used to prepare pharmaceutical compositions which are administered to treat cardiovascular and thrombo-embolic diseases associated with platelet aggregation.
