  • Patent number: 6355249
    Abstract: A process for commercial extraction of saponins from quinoa, and optionally for the formation of corresponding sapogenins. The saponin extraction process comprises contacting a saponin-containing part of a quinoa plant with an aqueous alcohol solution containing an alcohol selected from the group consisting of methanol and ethanol to form a saponin-containing solution and an extracted solid residue, removing the alcohol from the saponin-containing solution to leave a saponin-containing aqueous solution, and evaporating water from the saponin-containing aqueous solution to produce a saponin-containing product.

  • 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: 6113908
    Abstract: Methods of treating dehulled or hull-less oat, i.e. oat groats, to produce oat pearlings, oat flour and oat bran products are described. Oat groats are abrasion milled to remove up to 15% by weight and produce pearled oat groats and pearlings. The pearlings are extracted sequentially with aqueous ethanol and hexane to produce an anti-irritant and a light oat oil, or with hexane to produce a dark oat oil and lipase. The pearled oat groats are steeped in an aqueous medium for up to 4 hours and then macerated to produce an enriched oat bran, from which an enriched beta glucan may be extracted; a refined oat flour, from which oat starch and oat protein may be extracted; and a pearled oat groat extract from which further products, such as an oat anti-irritant can be recovered.

  • Patent number: 5169660
    Abstract: An aqueous steeping process for producing a relatively pure bran and flour products from cereal grains such as oats, wheat and rye without conventional dry milling techniques. The aqueous steeped grains are macerated with an ethyl alcohol solution and the bran and flour products recovered therefrom. The aqueous alcoholic waste solutions are further processed by ion-exchange techniques to recover small quantities of high value by-products.

  • Patent number: 5036241
    Abstract: A piezoelectric laminate comprises a piezoelectric layer and an insulating substrate layer rigidly bonded thereto. During poling, conditions are established under which a poling potential is established at the boundary of the layers which insures that a substantial part of the poling voltage is dropped across the piezoelectric layer. The poling voltage is maintained for a period greater than the time constant under the poling conditions of the material to which the poling voltage is applied. In one embodiment, the poling conditions are achieved by substantially enhancing the conductivity of the substrate layer relative to that of the piezoelectric layer. In a second embodiment, an intermediate bond layer is selectively switched from a non-conductive to a conductive state in response to a selected stimulus so as to form an electrode for facilitating the application of a poling field directly across the piezoelectric layer.

  • Patent number: 4990348
    Abstract: Half products expandable or puffable by microwave or convection heat energy are prepared by (a) preparing a starch-containing material having a moisture content of not more than about 25%, (b) extruding the moisture-tempered material at a temperature of about 80.degree. to 110.degree. C. without causing expansion thereby producing a hot melt in a rope or piece form, and (c) cooling the extrudate without substantially lowering the moisture content for a time necessary to harden up. The half-products contain not more than about 25% of moisture in a glass-like rope or piece form and are shelf stable without preservatives. Substantial savings can be achieved in manufacture, storage, shipping, and handling because of the low processing temperature and the storage stability of the dense and hard products.
