A method of producing a carotenoid-containing composition including: obtaining a carotenoid-containing oil phase composition by heating an oil phase component mixed liquid containing a carotenoid component containing at least one crystalline carotenoid, and a (poly)glyceryl fatty acid ester having form 1 to 6 of a glycerin unit and from 1 to 6 of a fatty acid unit and in which the glycerin unit has at least one hydroxyl group, at a dissolution temperature of the carotenoid component or higher; and obtaining an oil-in-water emulsified composition by emulsifying under pressure the carotenoid-containing oil phase composition with an aqueous-phase composition comprising an emulsifying agent.
