  • Patent number: 8480904
    Abstract: A process for purifying a lipid composition having predominantly neutral lipid components having at least one long chain polyunsaturated fatty acid is disclosed. The process employs contacting the lipid composition with a polar solvent, such as acetone, wherein the solvent is selected such that contaminants are less soluble in the solvent than is the long chain polyunsaturated fatty acid. The process is typically conducted at cooler temperatures, including about 0° C. Upon precipitation of the contaminants from the lipid composition, a separation is conducted to remove the precipitated material from the lipid composition. The long chain polyunsaturated fatty acids can include ARA, DPA, EPA, and/or DHA. The process of the present invention effectively winterizes lipid compositions, thereby reducing the tendency of such compositions to become hazy.

  • Patent number: 5792503
    Abstract: The temperature sensitive differential of the solubilities of isoflavones is used to separate them by heating an aqueous soy molasses feed stream. The temperature of the feed stream is increased to select an isoflavone. Then the heated feed stream is passed through an ultrafiltration membrane. The resulting permeate is cooled to crystallize the isoflavone. Or, the permeate may be put through a resin adsorption process in a liquid-chromatography column to separate out the desired isoflavone. Various processes are described for drying and recrystallizing the resulting isoflavone solids.

    Abstract: The temperature sensitive differential of the solubilities of isoflavones is used to separate them by heating an aqueous soy molasses feed stream. The temperature of the feed stream is increased to select isoflavone fractions. Then the heated feed stream is passed through an ultrafiltration membrane. The resulting permeate is cooled to crystallize the isoflavone fractions. Or, the permeate may be put through a resin adsorption process in a liquid-chromatography column to separate out the desired isoflavone fractions.

  • Patent number: 5034389
    Abstract: The invention involves a riboflavin composition comprising about 70% to about 90% by weight riboflavin and about 10% to about 30% by weight of a bulking agent selected from the group consisting of yeast, mold, fungi, bacteria and a mixture thereof, and having a bulk density greater than a riboflavin product having a purity of at least about 90% by weight. The riboflavin composition has improved flowability and reduced electrostatic charge relative to riboflavin products having a purity of at least about 90% by weight. The invention also involves a method for producing the riboflavin composition. The method comprises the steps of mixing riboflavin having a purity of at least about 90% by weight, a volatile, non-toxic liquid, and the bulking agent to produce a blend, and drying the blend.
