ABSTRACT:
A process is described for clarifying a crude inulin extract by ultrafiltration and separating an aqueous inulin solution containing carbohydrates having a range of degrees of polymerization into fractions having different average degrees of polymerization which comprises subjecting an aqueous inulin solution to ultrafiltration through a membrane having a predetermined pore size whereby inulin fractions having average degrees of polymerization less than a predetermined value pass through said membrane as permeate and inulin fractions having average degrees of polymerization greater than said predetermined value are collected as retentate.
