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.

Oat extracts: refining, compositions and methods of use

Cereal &#x3b2;(1-3) &#x3b2;(1-4) glucan is used as a film or coating agent to produce clear, edible, biodegradable, delivery, lubricating, and protecting agents. Cereal &#x3b2;(1-3) &#x3b2;(1-4) glucans are distinctive polymers of glucose differentiated from other polymers by not only their source but also their physicochemical properties. The &#x3b2;(1-3) &#x3b2;(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 &#x3b2;(1-3) &#x3b2;(1-4) glucan. The &#x3b2;(1-3) &#x3b2;(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.

A simple and efficient method for the production of a stable, clear and high-potency oat extract, containing avenanthramide, is disclosed. The method employs the use of a differential dissociation constants and ultra filtration to stabilize extract, prevent the loss of functional activity as an anti-irritant and anti-oxidant.

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.

Preparation of novel gels for the purification of non-polar extractives

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.
