Process for obtaining, by separation, highly pure water-soluble polydextrose

摘要

A process for obtaining, by separation, highly pure, water soluble polydextrose using a continuous simulated moving bed system. The process involves separation from a crude polydextrose mixture containing 75-95 wt % polyglucose, 2-10 wt % glucose, 1-5 wt % anhydroglucose, 1-5 wt % sorbitol and 0.5-3 wt % citric acid. The highly pure, i.e., over 99.2%, water soluble polydextrose obtained by this process can be used as a low calorie sweetener in diet foods and drinks and does not have a bitter after taste.
