  • Patent number: 8092842
    Abstract: A process for extracting phytochemicals from plants. The process generally comprises controllably slurrying a selected plant material in a volume, adding a selected enzyme the slurry while it is controllably agitated, then heating the controllably agitated slurry-enzyme mixture to a temperature from the range of 40° C. to 110° C., and then maintaining the slurry-enzyme mixture at that temperature for a selected period of time. The slurry is then separated into a solids fraction and a liquids fraction that contains extracted phytochemicals. The liquids fraction is controllably de-watered to produce a fluid extract concentrate. The liquids fraction may optionally be dried to produce a dried extract concentrate. Suitable enzymes for use with this process include ?-amylases, ?-amylases, endo-?-1,4-glucanases, cellobiohydrolases, cellulases, hemicellulases, ?-glucosidases, ?-xylosidases, xylanases, pullulases, esterases and mixtures thereof.

  • Patent number: 8003813
    Abstract: A process for separating a blend of saturated and unsaturated fatty acids or saturated and unsaturated fatty acid alky esters into a first fraction enriched with the saturated fatty acids or saturated fatty acid alkyl esters and a second fraction enriched with unsaturated fatty acids or unsaturated fatty acid alkyl esters. When separating fatty acids, the process includes the steps of (a) saponifying a blend of long chain saturated and unsaturated fatty acids to form free fatty acids, (b) complexing the free fatty acids with urea, and (c) separating the urea complexed free fatty acids into a first fraction enriched with saturated free fatty acids and a second fraction enriched with unsaturated free fatty acids.
