Extraction of carotenoids with supercritical CO₂

Extraction of carotenoids with supercritical CO2

"We live in a world of mixtures - the air we breathe, the food we eat, the gasoline in our automobiles ...:" [1]. Therefore raw materials as well as synthetic products have to be separated into desired and undesired componentsfor further use. Since 1979 the gentle CO2 extraction processis used at NATECO2 . Most of the commercial CO2 -extraction-plants work at pressures lower than 300 bars. With ascending pressure the solubility for different substances is rising. Consequently also the extraction of carotenoids with CO2 in an effective and economical way is possible through higher pressures.
