Supercritical CO2 Extraction and Fractionation Refining of Capsanthin
The supercritical CO2 fluid fractionation (SFEF) method can effectively remove the yellow and spicy components in the pigment under lower pressure, and at the same time, the red pigment and more insoluble components can be realized when the pressure continues to rise to a certain extent. Such as the separation of resin and pectin, in this way, high-quality capsicum red pigment with complete depigmentation and low impurity content can be obtained.
