  • Publication number: 20040140584
    Abstract: Disclosed is a cold-water soluble starch and a process for preparing same. Generally, the process comprises providing a hydroxyalkyl starch and applying a shearing force to the starch in an extruder in the presence of moisture, the force and the moisture each being sufficient to gelatinize at least substantially all of the granules of the starch to thereby form a sheared starch. The starch is heated to its gelatinization temperature after the starch has passed partially through the barrel of the extruder, with the moisture being maintained at a level sufficiently high to allow gelatinization but sufficiency low to protect the starch from becoming too sticky to extrude. The extruded starch product thus formed may be used in connection with a number of film-forming, coating, and other applications.

  • Publication number: 20040138444
    Abstract: Disclosed are derivatized malto-oligosaccharides and methods for the preparation thereof. In accordance with the disclosed invention, a malto-oligosaccharide is hydrogenated to thereby obtain a hydrogenated malto-oligosaccharide, and the resulting hydrogenated malto-oligosaccharide is derivatized, such as via oxidation, esterification, etherification, or enzymatic modification. The derivatization of such hydrogenated malto-oligosaccharides results in a surprisingly low level of a formation of by-products and products of degradation. In a particularly preferred embodiment of the invention, a mixture of malto-oligosaccharides is catalytically hydrogenated under reaction conditions suitable to substantially preserve the degree of polymerization (DP) profile of the mixture. The resulting malto-oligosaccharide mixture then is derivatized to form a derivatized malto-oligosaccharide mixture.

  • Publication number: 20040091324
    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: 20040053886
    Abstract: Disclosed are saccharide-derivatized oligosaccharides. The derivatized oligosaccharides preferably are prepared by extruding a malto-oligosaccharide mixture with a saccharide or mixture of saccharides having a DP ranging from 1 to 4. The products are low in digestibility, and thus in various embodiments are suitable for use as bulking agents, for controlled energy release products, and for other purposes.

  • Publication number: 20030204081
    Abstract: Disclosed are a method for the reduction of an oligosaccharide mixture and an oligosaccharide mixture prepared thereby. In accordance with the disclosed invention, a mixture of oligosaccharides having a given DP profile is reduced to a DE of essentially zero by catalytically hydrogenating the mixture under reaction conditions sufficient to preserve the DP profile of the mixture, which reaction conditions typically include a reaction temperature ranging from about 50° C. to about 150° C. and a reaction pressure ranging up to about 1500 psi. Surprisingly, when the mixture is a malto-oligosaccharide mixture, the reduced mixture will have a superior color-fastness and thermal stability as compared to a similar unreduced mixture of malto-oligosaccharides, and also low reactivity towards nitrogen-containing species.

  • Publication number: 20030202996
    Abstract: Disclosed are a fluid absorber, a method for preparing a fluid absorber, and a method for absorbing fluid from the skin. The disclosed method for preparing a fluid absorber generally comprises the steps of selecting a starch and an enzyme for hydrolysis of the starch, determining a fluid absorption optimum hydrolysis level for the starch, and ezymatically hydrolyzing the starch to approximately the optimum level thus determined. The starch alternatively may be hydrolyzed with acid hydrolysis without the use of an enzyme catalyst. The disclosed method for absorbing fluid from the skin includes the step of applying a fluid absorbing effective amount of a fluid absorber thus prepared. Absorption properties of the fluid absorber of the invention are comparable to or exceed those of commercially available skin fluid absorbers, such as talc and unmodified corn starch.
