PRODUCTION OF INDIGESTABLE HETEROPOLYSACCHARIDE

摘要

PURPOSE:To obtain the subject polysaccharide excellent in indigestibility and low-calorie property and useful for foods, etc., by dissolving a decomposed starch together with a specified saccharide in an inorganic acid, carrying out pulverizing and subsequently heating the powdered material without using water. CONSTITUTION:A decomposed starch is dissolved in an inorganic acid (e.g. dilute hydrochloric acid; preferably in an amount of <=10wt.% on 1wt.% hydrochloric acid base based on raw material mixture) together with one or more selected from monosaccharides (e.g. xylose) except glucose and homo- and hetero-oligosaccharides (e.g. lactose) except glucooligosaccharides (Ratio thereof mixed is preferably 25-300wt.% based on decomposed starch). The obtained solution is dried and pulverized and the resultant powder is subsequently heated preferably at 100-200 deg.C without using water, thus obtaining the objective polysaccharide.
