The present invention relates to filamentous fungal host cells and particularly Trichoderma host cells useful for the production of heterologous granular starch hydrolyzing enzymes having glucoamylase activity (GSHE). Further the invention relates to a method for producing a glucose syrup comprising contacting a granular starch slurry obtained from a granular starch substrate simultaneously with an alpha amylase and a GSHE at a temperature equal to or below the gelatinization temperature of the granular starch to obtain a composition of a glucose syrup.

A cosmetic composition is provided to achieve a soft focus effect. Imperfections in skin complexion can be hidden. The composition includes a water-insoluble partially hydrated granular starch having an average particle size ranging from about 500 to about 10,000 nm, a spherical alumina having a refractive index from 1.6 to 1.9 and average particle size from about 5 to about 300 nm, an inorganic material in flat, platy form having an average particle size ranging from about 0.1 to about 30 micron and a cosmetically acceptable carrier.

The present invention is directed to a yeast strain, or strains, secreting a full suite, or any subset of that, full suite, of enzymes to hydrolyze com starch, corn fiber, lignocellulose, (including enzymes that hydrolyze linkages in cellulose, hemicelhiiose, and between lignin and carbohydrates) and to utilize pentose sugars (xylose and arabinose). The invention is also directed to the set of proteins that are well expressed in yeast for each category of enzymatic activity. The resulting strain, or strains can be used to hydrolyze starch and cellulose simultaneously. The resulting strain, or strains can be also metabolically engineered to produce less glycerol and uptake acetate. The resulting strain, or strains can also be used to produce ethanol from granular starch without liquefaction.; The resulting strain, or strains, can be further used to reduce the amount of external enzyme needed to hydrolyze a biomass feedstock during an Simultaneous Saccharification and Fermentation (SSF) process, or to increase the yield of ethanol during SSF at current saccharolytic enzyme loadings. In addition, multiple enzymes of the present invention can be co-expressed in cells of the invention to provide synergistic digestive action on biomass feedstock. In some aspects, host cells expressing different heterologous saccharolytic enzymes can also be co-cultured togetherand used to produce ethanol from biomass feedstock.

An inhibited non-pregelatinized granular starch suitable for use as a food ingredient in substitution for a chemically modified starch may be prepared by heating a non-pregelatinized granular starch in an alcoholic medium in the presence of a base and/or a salt. Steam treatment may be used to enhance the extent of inhibition.

Disclosed are a method and process for preparing a hydroxyalkyl starch. In accordance with the disclosed invention, the starch is treated with an enzyme under conditions to increase the susceptibility of the starch to hydroxyalkylation by a hydroxyalkylating agent. After the starch is so treated, the starch is hydroxyalkylated with a hydroxyalkylating agent. The hydroxyalkylation reaction can proceed to provide a starch having an MS greater than about 0.2, while still remaining in granular form in the aqueous suspension. The method of the invention thus provides a granular starch having a higher MS than is otherwise attainable via a reaction in aqueous media.

The invention relates to a process of producing a fermentation product, such as ethanol, from starch-containing material, including i) subjecting starch-containing material to an alpha-amylase, ii) subjecting the material obtained in step i) to an alpha-glucosidase and/or a maltose-generating enzyme, and iii) fermenting the material in the presence of a fermenting organism, such as yeast. Alternatively the invention relates to a process of producing a fermentation product from starch-containing material, preferably granular starch, which process comprises: a) subjecting starch-containing material to an alpha-glucosidase and optionally a glucose-generating and/or maltose-generating enzyme, and b) fermenting the material in the presence of a fermenting organism.

The present invention concerns a method of producing glucose from a granular starch substrate comprising, contacting a slurry comprising granular starch obtained from plant material with an alpha-amylase at a temperature below the starch gelatinization temperature of the granular starch to produce oligosaccharides and hydrolyzing the oligosaccharides to produce a mash comprising at least 20% glucose and further comprising fermenting the mash to obtain ethanol.

A composition is disclosed that comprises:

• • (A) from about 65 wt % to about 10 wt % of a polyolefin resin:
  • (B) from greater than 30 wt % up to about 90 wt % of a granular starch; and
  • (C) from about 0.1 wt % to about 10 wt % of a functionalized polyolefm coupling agent, which agent improves the mechanical stiffness and strength of the polyolefin/granulated starch composites.

A rapidly-hydratable oxidized resistant starch having a cold-water hydration at least 20% greater than the resistant starch before oxidation, makeable by oxidation with an oxidizing agent selected from the group consisting of periodate, chromic acid, permanganate, nitrogen dioxide, and alkali metal hypochlorites. The starch may be made by a process for preparing a rapidly-hydratable resistant starch comprising the steps of swelling starch granules in the presence of alkali and/or heat, dispersing at least one cross-linking agent, mixing said dispersion, adding an oxidizing agent to said dispersion, and agitating said dispersion.

The invention discloses potato raw slurry and starch flour used for staple foods and a production process thereof. The production process of the potato raw slurry comprises the steps of selecting potatoes as a raw material, washing and peeling the potatoes, slicing and soaking the potatoes, cleaning and draining the potatoes, pulping the potatoes to obtain slurry, centrifuging the slurry, treating a filtrate, and drying the filtrate. The potato starch flour is then subjected to granulation to obtain granular whole potato starch flour. The production process of the potato starch flour and the granular starch flour can avoid gelatinization of the potato starch, can maintain the color, fragrance, taste and protein activity of the potatoes, and solves a problem of properties of potato knead in process of staple foods, and has important significance of promoting potato staple foods.

The present invention provides processes for production of wort and beer from a granular starch adjunct grist mashed-in at a temperature below the gelatinization temperature of said starch.
