  • Starch
    Publication number: 20070142325
    Abstract: Production of purified, parenterally administrable starch by washing starch containing more than 85% amylopectin in order to remove surface-localized proteins, lipids and endotoxins, subjecting the starch to a molecular weight reduction by acid hydrolysis, and optionally removing residual water-soluble proteins. Purified starch and microparticles based on such starch.
    Type: Application
    Filed: February 2, 2007
    Publication date: June 21, 2007
    Inventors: Nils Gustavsson, Monica Jonsson, Per Berden, Timo Laakso, Mats Reslow
  • Pharmaceutically acceptable starch
    Publication number: 20040019014
    Abstract: Production of purified, parenterally administrable starch by washing starch containing more than 85% amylopectin in order to remove surface-localized proteins, lipids and endotoxins, dissolving the starch in aqueous medium, molecular weight reduction by shearing, and optionally removal of residual water-soluble proteins, preferably by anion exchange chromatography.
    Type: Application
    Filed: July 28, 2003
