Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Cationic polysaccharide derivatives are prepared by reacting a polysaccharide with a polycationic reagent having one polysaccharide reactive group and at least two cationic groups. Suitable reagents include polycationic alkyl, aryl, alkaryl, cycloaliphatic, or heterocyclic amines, some of which are novel compositions. The polycationic polysaccharide derivatives prepared from these reagents are useful in the manufacture of paper.

Abstract: This invention relates to a process for chemically modifying polysaccharides in a densified fluid. In particular, the modification includes esterification and/or etherification of a starch in supercritical carbon dioxide. The process is advantageous in that it allows for a high degree of substitution without the use of organic solvents or repeated reactions.
