  • Patent number: 6664389
    Abstract: Highly resistant granular starches may be produced which have unique and useful properties, including high enzyme resistance, dietary fiber, a unique molecular weight distribution, a high melting temperature and a high heat of gelatinization (Delta H) indicative of excellent processing tolerance. These starches may be prepared for example by heating a high amylose starch having at least 40% by weight amylose content and at a percent moisture and temperature insufficient to destroy the granular nature of the starch, and digesting the amorphous regions using alpha-amylase or a chemical reagent.

  • Patent number: 5886076
    Abstract: A polymer comprising styrene or substituted-styrene and carboxylated monomer is prepared by a solution polymerization process, comprising first a polymerization step, followed by a neutralization step, and then a distillation step. The polymers have relatively low molecular weights, generally below about 10,000, and can have higher styrene content than has hither been possible. The polymers are found to have good soil release properties and so to be particularly useful in cleaning compositions for fabric or hard surface cleaning.
