  • Patent number: 7910339
    Abstract: The invention provides a process for producing polysaccharide gum comprising extracting a plant material with an aqueous solvent to produce a polysaccharide gum-containing extract; contacting the extract with at least one proteolytic enzyme to at least partially digest proteins in the extract; adding an organic solvent to the extract to precipitate the polysaccharide gum; and collecting the precipitated polysaccharide gum.
    Type: Grant

  • Publication number: 20090320353
    Abstract: Methods for recovery of concentrates of lubricating compounds and biologically active compounds from vegetable and animal oils, fats and greases that allow separation of triglycerides, from components with higher lubricity or biological activity or enrichment protocols that increase the concentration of high lubricity or biologically active compounds in the triglyceride. The triglycerides are transesterified with a lower alcohol to produce alkyl esters. Following the conversion process the esters are separated from high molecular weight high lubricity compounds and biologically active compounds by distillation. The esters have some lubricity and may be sold as pollution reducing fuel components.

  • Publication number: 20090137829
    Abstract: Methods for preparation of a unique superbase catalyst consisting of mixture of polyether alcohol and base in which a polyether alcohol superbase is produced by the removal of water or alcohol at elevated temperatures to form a polyether alcohol alkoxide. The superbase catalyst is useful in, but not limited to, quantitative isomerization of alkyl esters of vegetable oils containing interrupted double bond systems to yield esters with conjugated double bond systems, alkylations, arylations, acylations, aminations, condensations, eliminations, isomerizations, rearrangements, and Wittig reactions.

  • Patent number: 6822104
    Abstract: Methods for sequential saponification and quantitative isomerization of glyceride oils containing interrupted double bond systems, with alkali in a polyether alcohol solvent to yield soaps with conjugated double bond systems are disclosed. The novel properties of the polyether alcohols allow the removal of water added with the alkali by boiling. The preferred embodiment uses a vegetable oil rich in linoleic acid such as sunflower or safflower oil, potassium hydroxide, phosphoric acid to neutralize the soaps. The reaction forms equal quantities of 9Z,11E-octadecadienoic acid and 10E,12Z-octadecadienoic acids.

  • Patent number: 6420577
    Abstract: Methods for simultaneous saponification and quantitative isomerization of glyceride oils containing interrupted double bond systems, with alkali in water to yield soaps with conjugated double bond systems are disclosed. Novel methods of hydrolysis of the soap product with acid to form fatty acid-water emulsions and the breaking of those emulsions are also disclosed. The preferred embodiment uses a vegetable oil rich in linoleic acid such as sunflower or safflower oil, potassium hydroxide, phosphoric acid to neutralize the soaps, and an emulsion breaking compound which can include ethanol or other monohydric alcohol, tannins (either hydrolysable or condensed tannin) or polyethylene glycol. The reaction forms positional and geometric isomers of conjugated linoleic acid and the preferred isomer mixture is controlled by a combination of agitation, precisely controlled heating and rapid initiation and termination of the reaction. The reaction product composition may be enriched by crystallization.

  • Patent number: 6264853
    Abstract: A substanially pure chemically bound complex is derived from flax containing secoisolariciresinol diglucoside, cinnamic acid glycosides and hydroxy methyl glutaric acid. The complex is obtained by preparing an aqueous aliphatic alcoholic extract from flax and subjecting this aqueous extract to ultrafiltration whereby low molecular weight species remain with a filtrate and higher molecular weight species comprising the separated complex are retained.

  • Patent number: 5705618
    Abstract: A process is described for extracting lignans from flaxseed which comprises contacting a substantially oil-free flaxseed meal with an aliphatic alcohol solvent, e.g. a mixture of methanol or ethanol with water, to extract lignans into the alcohol solvent and separating residual solids from the lignan-rich alcohol solvent. The lignan-rich alcohol solvent is concentrated by removing solvent therefrom and the lignan concentrate obtained is subjected to a base-catalyzed hydrolysis to liberate lignans therefrom in a non-complexed form. Thereafter, the hydrolyzed concentrate is subjected to either a liquid/liquid partition, e.g. by an ethyl acetate/water system, or anion exchange to further enrich the lignans and the lignan-enriched solution thus obtained is subjected to chromatographic separation to isolate lignans at a purity of greater than 90 percent. The lignan, secoisolariciresinol diglucoside, was found in amounts of up to 20 mg per gram of defatted flaxseed.
