  • Patent number: 6800308
    Abstract: The present invention relates to a process for the aqueous extraction, fractionation and enzymatic treatment of oilseed materials to generate valued products with no significant low value by-product or waste streams. In particular, the fractionation scheme generates a protein-fiber feed ingredient principally for use with ruminant animals and a second dephytinized high protein fraction. The dephytinized high protein fraction has value as feed ingredient for a variety of species of animals.
    Type: Grant
    Filed: July 23, 2003
    Date of Patent: October 5, 2004
    Assignee: University of Saskatchewan Technologies Inc.

  • Patent number: 5989620
    Abstract: A high temperature extrusion process is provided for the production of legume pasta products. A dough mixture having a moisture content in the range of 15 to 40% is processed in a twin screw extruder or in a single screw extruder at a barrel temperature in the range of 70 to 135.degree. C. and extruded through a die to form legume pasta products. The resulting products have a superior texture and integrity compared to legume pasta products produced by the traditional method.

  • Patent number: 5827372
    Abstract: A starch cationization process comprises suspending the starch in an aqueous alcoholic alkaline solvent containing a critical level of water (starch to water ratio 1:3 to 3:1), heating the reaction mixture for a few minutes at 30.degree.90.degree. C., adding a cationizing reagent such as 3-chloro-2-hydroxypropyl-trimethylammonium chloride, heating for 1-24 hours at 30.degree.-80.degree. C., neutralizing, centrifuging, washing and drying of the cake to yield cationic starches with degrees of substitution of 0.01 to 0.12. Amphoteric starches are produced by simultaneous or sequential reaction of an anionic reagent with or after the cationic reagent in the aqueous alcoholic alkaline solvent. Solvent recovery and concentration of effluent solids is facilitated by distillation.

  • Patent number: 5697127
    Abstract: A sealed container for pills on a clip such as a money clip. Preferably, the container is hermetically sealed and suitable for holding moisture sensitive pills in a fashion which prevents the sensitive substances from being adversely affected during transport. The container has a main body having a first finger and a second finger with a generally U-shaped spring forming joint therebetween. The first finger has an upper surface upon which a container base portion is mounted. The container base portion has a threaded portion along the peripheral sides thereof, and a sealing surface at the upper reaches thereof. A cap is provided with threads complimentary to those on the outside of the container base portion, so that the cap can be removably affixed to the container base portion. A sealing portion, preferably of the O-ring type, is used to form a seal between the container base portion, at the sealing surface, and the cap.
