CA 2424931

Production of purified, parenterally aministrable 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.

La présente invention concerne la production purifiée, d'un amidon qu'on peut administrer par voie parentale. Cette production consiste à laver un amidon contenant plus de 85 % d'amylopectine de façon à retirer les protéines localisées en surface, des lipides et des endotoxines, à soumettre cet amidon à une réduction de masse moléculaire par hydrolyse acide, et éventuellement à retirer des protéines résiduelles solubles dans l'eau. Cette invention concerne aussi l'amidon purifié et des microparticules à base de cet amidon.
