  • Purification of polysaccharides
    Patent number: 5756721
    Abstract: A steam-stripping process suitable for the removal of impurities from polysaccharides, including soluble starch hydrolysates, is disclosed herein. This process may be used in combination with other purification processes, such as ultrafiltration, ion exchange, treatment with activated carbon, as well as bleaching process. Soluble starch hydrolysates may also be purified by a combination of ultrafiltration or activated carbon treatment and bleaching. In these processes, the polysaccharide or the soluble starch hydrolysate produced is bland in flavor, free of off-odor, optionally, lighter or white in color and suitable for use in systems requiring these characteristics.
