ABSTRACT:
A process for readily isolating and recovering highly pure erythritol at a high crystallization yield from an erythritol-containing culture medium, which contains erythritol together with various impurities such as salts, coloring materials and polysaccharides, through chromatographic separation with the use of a strongly acidic cation exchange resin. The process of the present invention can be continuously operated, since the lowered separation capability of said cation exchange resin can be readily restored by treating the same with a warm alkali solution.
