An Improved Process For Producing Pyrogen Free Narrow Molecular Weight Distribution Tetrastarch .
Abstract: An improved process for producing pyrogen free Tetrastarch (130/0.4). This process involves hydrolyzing the waxy starch to achieve molecular weight distribution between 110,000 to 150,000 daltons and molar substitution between 0.35 to 0.45 is achieved by attachment of hydroxyethyl group. Organic solvent used till tetra starch becomes free from salt and glycol content. Microfiltration is used to reduce microorganism load (bio-burden) and ultrafiltration to reduce pyrogen and low as well as high molecular weight undesired fragments. Spray dryer is used to obtain dried Tetra Starch with the minimum moisture content.
