Abstract

Disclosed is carboxymethyl inulin having a degree of substitution (DS) ranging from 0,15 to 2,5, preferably from 0,5 to 1,5, a process for the preparation of said carboxymethyl inulin by reacting inulin at a concentration of at least 100 g/l, preferably at least 200 g/l, at elevated temperature with an aqueous alkaline solution of monochloroacetic acid, followed by working up the reaction mixture according to a method known in the chemical art, and the use of said carboxymethyl inulin as inhibitor for the crystallization of calcium carbonate.
