摘要：
A novel process for producing powdered carotenoid preparations, in which a suspension of a carotenoid in a high-boiling oil is brought into contact with superheated steam during a maximum period of 30 seconds, and subsequently emulsified the liquified solution of said carotenoid in oil produced by said contact with superheated steam in an aqueous solution of a colloid and then spraying and drying said emulsion to a powder.
