Soluble highly branched glucose polymers having reducing sugar, useful in the food and pharmaceutical applications in human and animal, in enteral and parenteral nutrition fields like glycemia regulating agent and for peritoneal dialysis

摘要

Soluble highly branched glucose polymers having a reducing sugar content of less than 3.5%, preferably less than 1%, exhibit a alpha -1,6 glucosidic bonds rate of 20-30% and a molecular weight of 20/*10 3 to 30/*10 3, determined by light diffusion. Independent claims are included for: (1) the preparation of the soluble highly branched glucose polymers comprising preparing an aqueous starch solution or its derivatives, preferably waxy starch (a dry matter of 10-30 wt.%), treating the solution using a branching enzyme then with a saccharification enzyme like amyloglucosidase (preferred) or -beta -amylase, fractionating to recover high molecular weight fractions and collecting the obtained highly branched glucose polymers; (2) a composition for food and pharmaceutical applications for human and animals, comprising the highly branched glucose polymers obtained by the process; and (3) a solution for peritoneal dialysis, comprising the soluble highly branched polymers as an osmotic agent.
