The present invention relates to a process for purifying starches. More particularly, the invention relates to a method of removing off-flavors, off-odors, and off-colors from starches by extraction of the components causing the off-flavors, off-odors, and off-colors with a fluid in the supercritical or liquid phase.

Process for purifying starches

The present invention provides an efficient acid conversion process by which native and modified starches may be treated to afford products with low viscosity and a higher proportion of lower molecular weight compounds than the corresponding aqueous acid conversion processes. Such converted starches demonstrate unique properties and, accordingly, are useful in a variety of products.

Thermally converted starches and the method of preparation thereof

The present invention is directed to cold water swellable starches exhibiting delayed viscosity development, preparation and use thereof. The cold water swellable starches are prepared using methods known in the art and then are compacted. These starches provide all the advantages of CWS starch, including texture, heavy body, glossy sheen, and viscosity. However, the rate of hydration may be controlled to delay viscosity development. Such starches may be used for a variety of industrial applications including food products, personal care products, cleansers, liquid detergents and fabric softeners, oil-well drilling, and paints and allow for easier processing of such products.

Cold water swellable starches exhibiting delayed viscosity development, preparation and use thereof

The present invention is directed to the use of starch phosphate esters as an expansion and/or texture aid in food or industrial products. The invention further provides the formulations and improved expanded products containing starch phosphate esters, particularly extruded breakfast cereals and snacks.

Starch phosphate ester for use as an expansion aid

The present invention is directed to a process of preparing starch phosphate monoesters, optionally in the presence of oligosaccharides, having improved reaction efficiency and reduced side reactions. The invention also includes the improved starch phosphate monoester products, characterized by high viscosity and low level of residual salts, their use in food and the enhanced food compositions prepared from them.

Starch phosphate ester composition, process and method of use in food

Paper having improved retention properties made by the addition to the papermaking system of a combination of cationic starch and starch phosphate, the starch combination having a select net zeta potential.

Starch polymer combinations used in papermaking

The use in papermaking of an amphoteric starch additive which contains a phosphate functional group and is made under anhydrous conditions while in a fluidized state, provides advantageous paper properties and improved wet end performance.

Amphoteric starches used in papermaking

The present invention is directed to low volatile organic compound aerosol hair cosmetic compositions which contain nonionically derivatized starches optionally hydrolyzed and/or ionically modified, about 5-55% propellant, up to 50% solvent, and water. Such compositions provide a clear solution with a low viscosity, good spray caracteristics, a clear, non-tacky film, good stiffness, and improved humidity resistance.

Aerosol hair cosmetic compositions containing non-ionically derivatized starches

A biodegradable, structured shaped product having good flexibility or rigidity properties is provided by extruding starch having a relatively large defined particle size and preferably containing a nucleating agent.

Expanded starch-based shaped products and the method of preparation thereof

The present invention provides a method for preparing a dry, sweetened, extruded, ready to eat flaked or puffed cereal. Cereal flours, sweeteners such as sugars and/or syrups, and other cereal ingredients are formulated with added water and about 4-28%, preferably 5-15% of selected pregelatinized spray-dried starches having an amylose content of at least about 70% or up to 25% of a preextruded fully dispersed high amylose flour having an amylose content of at least about 70%. The pregelatinized high amylose starch may be unmodified or converted and in granular or non-granular form. The cereal is extruded at a temperature of about 120-160&deg; C. and a pressure of about 100 to 500 psi.

Sweetened extruded cereals containing pregelatinized high amylose starches

A biodegradable, water dispersible shaped core product useful in winding or rolling and storage of paper goods is provided by extruding starch which has a particle size of 800 to 1200 microns into an expanded, closed cell starch product.

Starch-based core products for use in rolled paper goods

An expanded shaped product with improved flexural compressibility and surface properties comprising starch and a hydrophobically modified acid anhydride or its acid hydrolyzed counterpart and the method of preparing such product by extrusion.

Starchfoam products with improved flexibility/compressibility and the

A method of extruding starch under low moisture conditions of 25% or less by weight to form an expanded product is provided and includes feeding inlet starch to an extruder, the starch having a particle size distribution such that 30% or more by weight have a particle size of at least 180 microns. In one embodiment, the inlet feed starch is dried using a continuous belt dryer.

Method of extruding starch under low moisture conditions using feed

Biodegradable, expanded starch products are provided having increased resistance to water and high humidity and comprising low DS hydrophobic starch derivatives having the formula: ##STR1## where ST is starch, R is a dimethylene group, R' is a substituent hydrocarbon having 10 to 16 carbon atoms, Y is a metal, x is an integer equal to the valence of Y and derivative or ester group has a DS of from about 0.03 to 0.12.
