Method for producing carotenoid composition

摘要

The present invention provides an efficient method for industrially producing a naturally-derived carotenoid composition with a large amount of a carotenoid such as astaxanthin from a culture of a yeast of the genus Xanthophyllomyces without requiring any special extraction equipment and any complicated refinement process and without any need for organic solvents harmful to humans. Provided is a method for producing a carotenoid composition, including the steps of washing a carotenoid-containing yeast of the genus Xanthophyllomyces with an organic solvent (A) at 30° C. or lower, and extracting a carotenoid from the washed yeast with an organic solvent (B) at 10° C. to 70° C.

主权项

1. A method for producing a carotenoid composition, comprising:
washing a carotenoid-containing yeast of the genus Xanthophyllomyces with a first organic solvent at 30° C. or lower to obtain a washed yeast; and extracting a carotenoid from the washed yeast with a second organic solvent at 10° C. to 70° C. to obtain a carotenoid extract.
