High purity 9-cis-β-carotene-containing composition and process for producing the same |
| abstract |
(57) [Problem] To provide a high-purity 9-cis-β-carotene-containing composition and a production method thereof that can be carried out on an industrial scale. SOLUTION: After washing a dry powder of Dunaliella genus algae with ethanol, hexane is added and stirred, the filtrate obtained by filtration is concentrated, and hexane is added to the obtained semi-solid concentrate. Then, the filtrate obtained by filtration was concentrated, hexane was further added to the obtained oily concentrate, and the mixture was allowed to stand at a low temperature to precipitate a 9-cis-β-carotene-containing composition. |
