Process for preparing high purity maltitol powder

摘要

The present invention is a strong acid cation resin column was charged a stock solution of maltose and maltose content of 70-75% sequentially passed through decision- by size exclusion chromatography with a mobile phase separating the high-purity maltose solution over 96% maltose content depending on the molecular weight and size , 120~130 high temperature for the high-purity maltose solution under the presence of a ruthenium catalyst , 40~50 kg / of the high-pressure hydrogenation under the reaction and to produce a conversion rate of 99% or more of maltitol , a method of producing a maltitol purity of 98% or more dry grinding , characterized by bereavement Sikkim the resulting maltitol .
