摘要：
A process for the extraction of carotenoid dyes from pre-dried natural starting materials is described using compressed gases such as propane and/or butane in which organic entraining agents can be additionally added in order to facilitate and complete the extraction process. With the aid of this process highly concentrated carotenoid dyes are obtained in high yield.
