A process for manufacturing crystalline maltitol and crystalline mixture solid containing the same

摘要

Problem of Invention;To provide an economically advantageous process for manufacturing crystalline maltitol and crystalline mixture solid containing crystalline maltitol.;Means to Solve Problem;The process of this invention uses the syrup having a maltose purity of 81 to 90% as the starting material. The syrup is hydrogenated under the existence of catalyst, and then subjected to a chromatographic separation by using cation-exchange resin, resulting in an aqueous solution of maltitol having a maltitol purity of 94 to 99.9%. The aqueous solution is further crystallized in the presence of a seed crystal, subjected to a separation, cooled and kneaded so as to manufacture both crystalline maltitol and crystalline mixture solid containing crystalline maltitol at the same time.
