The present invention provides the excellent crystallization method suitable for production on the industrial scale for obtaining the reduced coenzyme Q10 crystal. The high-quality reduced coenzyme Q10 can be obtained in improving the slurry property and/or the crystallization yield by the method of present invention in which reduced coenzyme Q10 is crystallized in an aqueous solution, in particular, the method of crystallizing the reduced coenzyme Q10 by substituting an organic solvent solution containing the reduced coenzyme Q10 by water, the method of crystallizing the oily reduced coenzyme Q10 in an aqueous solution, or the like. |
