METHOD FOR PRODUCING INULIN

摘要

[Problem] To provide a process for conveniently and efficiently extracting, separating, and purifying (desalting and decoloring) inulin from chicory. [Solution] A defecated liquid of a chicory raw juice is softened with a strongly acidic cation exchange resin. The resulting liquid is desalted with a strongly acidic cation exchange resin and then with a weakly basic anion exchange resin, followed by decoloring with a strongly basic anion exchange resin, desalting with a weakly basic anion exchange resin, and drying. A standard inulin and a highly polymerized inulin can be conveniently and efficiently separated and purified by separating standard inulin and highly polymerized inulin from each other after the softening treatment, or after the final desalting treatment.
