  • Co-milling fiber for use in foods
    Patent number: 4865863
    Abstract: This invention is a process for rendering an edible fiber more easily hydratable for addition to food products. Edible fiber is co-milled in a multi-impact mill with sugar and optionally flour and starch. This co-milling improves the dispersion and the water absorbing rate of the fiber when it is added to food. The addition of fiber allows more water to be held, resulting in better and moister tasting food products. The invention also comprises the fiber product made according of this process.

  • Button type dispensing package
    Patent number: 4865231
    Abstract: A swivel-up type dispensing package is disclosed. The package includes a product chamber with an elevator therein to move the product axially. A feed screw and nut are associated with the elevator and relative rotary motion between the feed screw and nut serve to move the elevator axially. The package also includes a button adapted to be depressed by the user in a direction which is generally transverse to the axis of body of the dispensing package. The transverse movement of the button is converted to rotary input to either the feed screw or nut to cause one to rotate relative the other and thereby move the elevator. In the described embodiment the button has an integral pawl which during the transverse movement engages ratchet teeth affixed to a wheel mounted perpendicularly to the axis of the body, causing the wheel to rotate through an arc subtended by driven teeth.

  • Process for treating coffee beans to make a better-tasting coffee
    Patent number: 4857351
    Abstract: The invention is a method for treating coffee beans to make a better-tasting and improved aroma coffee. Green coffee beans are first partially roasted to a Hunter a-color between about 3 and about 9, under roasting conditions sufficient to increase the Hunter a-color of the beans by at least about 1.5 a-color units during the partial roasting step. The partially roasted beans are then treated with either an alkaline solution comprising water and a foodgrade base, or a coffee bean extract solution comprising water and from about 1% to about 12% coffee solids. Preferably, the partially roasted beans are treated by soaking them in the solution at a temperature between about 65.degree. F. (18.degree. C.) and about 120.degree. F. (49.degree. C.) for a time between about 2 hours and about 24 hours.
