  • Publication number: 20100297332
    Abstract: Disclosed is a process for treating a grain to form a product that is high in dietary fiber on the basis of dry solids content relative to the grain. Generally, the process includes subjecting the grain product to a destarching step, typically via aqueous treatment in warm water, followed by screening. The intermediate product thus formed is subjected to steam, typically in a jet cooking step, to yield a product that is higher in dietary fiber on a dry solids basis than the intermediate product previously formed. The grain is typically wheat bran, but may be other grains such as rice or oats.

  • Patent number: 7514018
    Abstract: Disclosed are dust suppressant and aggregate stabilization compositions. In accordance with the subject disclosure, hemicellulose is used as a dust suppressant and/or as a stabilization composition for aggregates such as a road bed or soil field. Other ingredients may be used in a composition in conjunction with hemicellulose. For instance, a lignin compound may be used to enhance dust suppression and/or aggregate stabilization. A surfactant may be used to decrease the viscosity of the composition. A crosslinking agent may be used to enhance the water resistance of the composition. A chloride salt may be added to increase the hygroscopicity of the composition.

  • Publication number: 20080121187
    Abstract: Disclosed is a method of washing a grain-based substrate, such as a spent grain germ. The grain-based substrate is contacted with steam and maintained in contact with steam for a time and at a pressure sufficient to liberate at least a portion of one odor component present in the substrate. Subsequently, at least a portion of the steam and at least some of the liberated odor component is separated from the balance of the substrate, thereby leaving a washed substrate. An additive, such as a soap or detergent, may be used in connection with the washing step. The grain-based substrate may be used in connection with an animal litter. In one embodiment, a litter is prepared from distiller's dried grain. Surprisingly, washing of the dried grains in accordance with the preferred teachings reduces the odor of the distiller's dried grains and yields a litter with excellent clumping properties.

  • Patent number: 6868802
    Abstract: An animal litter that includes seed meal is disclosed. In accordance with the invention, the animal litter comprises discrete plural particles of a seed meal, which particles tend to agglomerate into clumps when wetted. The litter of the invention absorbs liquids such as animal excretions, and substantially reduces the odor thereof. Preferably, the litter further includes a grain germ, such as corn germ.

  • Patent number: 6063178
    Abstract: Disclosed is a method for the preparation of a corrugating adhesive. The method includes the steps of extracting hemicellulose from a hemicellulose-containing plant source, separating the hemicellulose in a soluble phase from the insoluble portion of the hemicellulose-containing plant source, and mixing the hemicellulose-rich phase with starch to form an adhesive composition. The adhesive composition of the invention exhibits superior shear stability properties as compared with prior art adhesive compositions that incorporate pasted starches, and exhibits superior green tack as compared with prior art hemicellulose-based adhesives. Also disclosed are a corrugated board and a method for preparing same.
