摘要： Cationic polysaccharide derivatives are prepared by reacting a polysaccharide with a polycationic reagent having one polysaccharide reactive group and at least two cationic groups. Suitable reagents include polycationic alkyl, aryl alkaryl, cycloaliphatic, or heterocyclic amines, some of which are novel compositions. The polycationic polysaccharide derivatives prepared from these reagents are useful in the manufacture of paper.
摘要翻译：阳离子多糖衍生物通过使多糖与具有一个多糖反应性基团和至少两个阳离子基团的聚阳离子试剂反应来制备。合适的试剂包括聚阳离子烷基，芳基烷芳基，脂环族或杂环胺，其中一些是新的组合物。由这些试剂制备的聚阳离子多糖衍生物可用于纸的制造。

摘要： 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 processes or treatment with activated carbon, as well as with a bleaching process. Soluble starch hydrolysates may also be purified by a combination of ultrafiltration and bleaching or by a combination of activated carbon treatment and bleaching. In these processes, the polysaccharide or the soluble starch hydrolysate that is produced is bland in flavor, free of off-odor, optionally, lighter or white in color and suitable for use in food systems requiring these characteristics. Other purification process combinations which are disclosed for removal of undesirable flavors, odors and colors from polysaccharides include:
1. Ultrafiltration and carbon treatment; 2. Ultrafiltration and steam-stripping; 3. Steam-stripping and carbon treatment; 4. Ion exchange treatment and ultrafiltration; 5. Ion exchange treatment and steam-stripping; and 6. Ion exchange treatment and carbon treatment. A bleaching process may precede any of these processes. If ozone or a peroxide is employed, the bleaching step may follow any of these processes. Any of the processes may be combined with other processes disclosed herein to provide additional purification measures. The processes are particularly useful for purification of low molecular weight soluble polysaccharide hydrolysates, such as dextrins. These purified polysaccharides are used to improve foods and pharmaceutical products.
摘要翻译：本文公开了适用于从多糖（包括可溶性淀粉水解产物）中除去杂质的蒸汽汽提方法。该过程可以与其他纯化过程结合使用，例如超滤，离子交换过程或活性炭处理，以及漂白过程。可溶性淀粉水解产物也可以通过超滤和漂白的组合或通过活性炭处理和漂白的组合来纯化。在这些方法中，所生产的多糖或可溶性淀粉水解产物在风味上是平淡的，没有异味，任选地是浅色或白色，并且适用于需要这些特征的食品系统。公开的用于从多糖中去除不合需要的风味，气味和颜色的其他纯化方法组合包括：1.超滤和碳处理; 2.超滤和汽提; 3.汽提和碳处理; 4.离子交换处理和超滤; 5.离子交换处理和汽提; 和6.离子交换处理和碳处理。漂白过程可以在任何这些过程之前进行。如果使用臭氧或过氧化物，漂白步骤可以遵循任何这些方法。任何方法可以与本文公开的其他方法组合以提供额外的净化措施。该方法特别适用于纯化低分子量可溶性多糖水解产物，如糊精。这些纯化的多糖用于改善食品和药品。
