  • Patent number: 8815268
    Abstract: A simple and efficient method for the production of stable, clear, high-potency oat extracts is disclosed. The method employs the use of differential dissociation constants and ultrafiltration to stabilise extracts, prevent hazing, and prevent the loss of functional activity as an anti-irritant and anti-oxidant. Also disclosed are compositions of oat extracts derived from whole oat grains and oatmeal. Further disclosed are compositions of oat extracts for use in cosmetic, nutraceutical, therapeutic medical and veterinary preparations.

  • Patent number: 8632798
    Abstract: Cereal ?(1-3) ?(1-4) glucan is used as a film or coating agent to produce clear, edible, biodegradable, delivery, lubricating, and protecting agents. Cereal ?(1-3) ?(1-4) glucans are distinctive polymers of glucose differentiated from other polymers by not only their source but also their physicochemical properties. The ?(1-3) ?(1-4) forms a matrix to sequester other materials, such as pharmaceutical, medical and therapeutic agents, flavors, fragrances. The technology has applications to essential oils and non-aqueous materials that are rendered deliverable by the ?(1-3) ?(1-4) glucan. The ?(1-3) ?(1-4) glucan films described may be consumed whereby they dissolve in the mouth in a controlled manner and may be used for the delivery of pharmaceutical, medical or confectionery products.

  • Publication number: 20110059031
    Abstract: The present invention relates to oral compositions comprising a ? (1-3) ? (1-4) glucan and one, or more than one compound of interest. In particular, the present invention provides an oral composition comprising an effective amount of a ? (1-3) ? (1-4) glucan and an effective amount of one, or more than one of an antibacterial agent, a botanical extract, and a flavouring agent, and also provides a method of using this composition for maintaining fresh breath in a subject over a prolonged period of time.

  • Publication number: 20100303921
    Abstract: The present invention relates to pharmaceutical compositions comprising a ? (1-3) ? (1-4) glucan and a pharmaceutically active agent or a botanical extract. A method to extract and purify cereal ?-glucan is also described. The high purity of the cereal ?-glucan obtained according to the present invention allows for the preparation of clear, colourless viscous liquid preparations. These liquid preparations are stable to gelling effects when kept at ambient temperatures and low ash concentrations, and can be used to prepare the pharmaceutical compositions of the present invention.

  • Publication number: 20030150805
    Abstract: A process is described for the preparation f electrostatically-linked, aliphatic- or alicyclic-substituted anionic or cationic polysaccharide gels from readily available macroporous ionic polysaccharide chromatographic media, such as diethylaminoethyl (DEAE), quaternary aminoethyl (QAE) and sulfopropyl (SP) substituted polysaccharide gels. These novel gels are used for the isolation, recovery and purification of non-polar extractives using one or more extracting solvents from the group of lower alcohols, ketones, and water. The non-polar extractives may be alk(n)lyresorcinols, steroid, triterpenoid, cardiac glycosides and saponins, steryl ferulates and other phenolic acid conjugates, flavonoids, lipids, alcohol-soluble antimicrobials, prolamines or other alcohol-soluble proteolipid complexes.

  • Patent number: 6495140
    Abstract: A process is described for the isolation, recovery and purification of non-polar extractives using one or more extracting solvents from the group of lower alcohols, ketones, and water. The non-polar extractives may include one or more of the classes alk(en)lyresorcinols, steroid, triterpenoid and cardiac glycosides and saponins, steryl ferulates and other phenolic acid conjugates, flavoroids, polar lipids, alcohol-soluble antimicrobials, prolamines and other alcohol-soluble proteolipids complexes. The process uses an aliphatic-substituted polysaccharide gel matrix in a process of hydrophobic interaction chromatography, and involves the steps of absorption, washing and recovery, wherein the extractives are absorbed and desorbed in the presence of and as a result of the concentration and selection of the organic ste of regenerating the gel matrix for further use.
