Patent ID: 6861519

Claim:
Method for preparing soluble highly branched glucose polymers, comprising the following steps: an aqueous starch suspension or a solution of starch derivative having a dry matter content at least equal to 1% by weight is prepared, said suspension or said solution is treated with at least one branching enzyme at a temperature comprised between 25 and 80° C. for a period of 1 to 24 hours, at least one enzyme selected from the group consisting of α-amylase, β-amylase, amyloglucosidase and α-transglucosidase is caused to act on the suspension or on the solution thus obtained, a fractionation of the enzyme treated suspension or solution using at least one technique selected from the group consisting of membrane separations or chromatographies is carried out, so as to recover the high molecular weight fractions and low molecular fractions, collecting the highly branched glucose polymers corresponding to the high molecular weight fractions thus obtained.
