ABSTRACT:
The present invention provides a method of producing reduced coenzyme Q10crystals suitable for commercial scale production thereof.According to a method of the present invention of producing a reduced coenzyme Q10crystal which comprises a crystallization of reduced coenzyme Q10in a solution of alcohols and/or ketones, reduced coenzyme Q10crystal excellent in slurry properties and crystalline properties maybe obtained. Moreover, an isolation process including a crystal separation or the whole process including the isolation process maybe minimized and simplified. Thus, highly pure reduced coenzyme Q10may be obtained in a high yield.
