摘要:
A method for producing a composition containing carotenoid at a content of 80% or greater, characterized in performing extraction on a culture of a microorganism, a concentrate of the culture, or a dried substance thereof with at least one selected from the group consisting of lower alcohols, water-containing lower alcohols, lower dialkylketones and ethers; and then washing a precipitate, obtained by concentrating the extract solution, with at least one selected from the group consisting of lower alcohols, water-containing lower alcohols, hydrocarbon-based solvents and lower dialkylketones; and food, a pharmaceutical composition or a cosmetic substance comprising the carotenoid-containing composition.
