  • Low D.E. starch conversion products
    Patent number: 4298400
    Abstract: The present invention provides a process for preparing low D.E. starch hydrolysates and low D.E. conversion syrup products which are both liquid and solid. Starch is treated with bacterial alpha amylase to a D.E. less than 15. The hydrolytic action of the amylase is terminated by heat treatment and the resulting hydrolysate is further converted with bacterial alpha amylase to a D.E. between about 5 and about 20. From the resulting hydrolysate product is obtained a non-hazing syrup which is substantially completely water soluble.

  • Composition and production process for Fourdrinier fiberboard
    Patent number: 4212704
    Abstract: In a fiberboard composed of fibers bound together with a starch derivative produced by reacting maleic, phthalic, or succinic anhydride, or a combination of these anhydrides, with starch, an improvement in the Fourdrinier process for producing said fiberboard wherein the reaction product of the anhydride and starch is directly mixed, without drying, with fiber and other conventional ingredients, such as clay, and is then passed directly to the Fourdrinier machine.

  • Torrefied barley for brewer's mashes
    Patent number: 4165388
    Abstract: Torrefied, expanded barley for use as a partial replacement for malt in brewer's mashes is prepared by heating unmalted barley having a protein content of at least about 12% to a temperature sufficient to expand the barley to a degree that a given volume of barley before heating weights about 1.4 to about 1.75 times the weight of the same volume of barley after heating. Before heating, the unmalted barley preferably has a moisture content of about 12% to 20% by weight.
