Abstract:
Disclosed is a method for preparing a mixture of malto-oligosaccharides. Generally, a dry-milled corn fraction, such as a corn flour from which germ and fiber have been removed, is subjected to hydrolysis, typically catalyzed with acid or an enzyme such as an α-amylase enzyme, under conditions suitable to form a mixture of malto-oligosaccharides. A gluten fraction is removed and the enzyme is inactivated, such as with heat. The mixture of malto-oligosaccharides then may be recovered from remaining solids and purified.

Abstract:
A method for producing a low sodium salt composition, including aspects for producing fraction(s) of a selectable particle size is provided. Millable particles can be produced. The method does not require agglomeration to obtain larger-sized solids. The composition generally includes salt, such as sodium chloride, and one or more crystallization interrupters. The composition is in the form of amorphous particles, optionally in combination with other ingredients.
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.
Abstract:
The invention provides a method of producing a fermented beverage. A starch hydrolysate is fermented in the presence of yeast, a soluble nitrogenous yeast nutrient source, and an enzyme that releases fermentable carbohydrates from the starch hydrolysate to achieve a fermented beverage. The soluble nitrogenous yeast nutrient source is present in an amount sufficient to sustain fermentation of the starch hydrolysate to an inactivating alcohol concentration in the fermented beverage without being rate-limiting in the fermentation. The method can further comprise carbon filtration and ion exchange filtration to substantially remove impurities. A fermented beverage having substantially neutral flavor and substantially neutral odor prepared in accordance with the inventive method also is provided.
Abstract:
Disclosed is a sorbent that includes spent grain germ, seed meal, or a mixture thereof. The sorbent may be used to introduce a material into an environment. For instance, the sorbent may be used to introduce a control agent, such as an insecticide or larvicide, into an environment. The sorbent also may be used to remove an unwanted material from an environment. For instance, the sorbent may be used to sorb oil or a hazardous chemical that has been spilled. The disclosed sorbents are biodegradable over a wide range of environmental conditions.
Abstract:
Disclosed are starch granules prepared via treating starch with a glucoamylase enzyme. The starch granules prepared in accordance with the present invention are hydrophobic relative to native starch granules, and are suitable for use in numerous applications. Also disclosed are a porous starch product, a delayed release product, and a method for absorbing fluid from the skin. The delayed release product comprises a product carried within the pores of the porous granular starch. The method for absorbing fluid comprises applying a fluid-absorbing effective amount of the dried, ground granules.
Abstract:
Disclosed are drilling fluids suitable for use in connection with oil well drilling. The drilling fluids of the invention include in one embodiment a liquid base, an alkyl glucoside, such as methyl glucoside, and a borehole stability agent that includes a maltodextrin, a carboxyalkyl starch, a hemicellulose-containing material, or a mixture of the foregoing. In another embodiment, the drilling fluid includes a liquid base and desugared molasses solids, preferably in combination with an alkyl glucoside and more preferably in further combination with one of the aforementioned borehole stability agents. The drilling fluids of the invention surprisingly have a reduced tendency to swell shale as compared with known drilling fluids. Also disclosed are a drilling apparatus and process. The drilling apparatus includes a drill string, which may be conventional, that is fluidically coupled to a source of drilling fluid, the source of drilling fluid including the drilling fluid of the invention. The process of the invention includes the step of circulating the drilling fluid of the invention through a drill string during borehole drilling.
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.
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.
