Supercritical CO2 Fluid Extraction (SCFE) is a new green separation technology emerging in the world today. This separation technology generally does not need to add any chemical reagents in the treatment process, and the separated substances will not be polluted, which can meet the green requirements of people for medicines, foods, health-care products and cosmetics to the greatest extent. At the same time, this separation technology has the advantages of high extraction efficiency, high product quality, highcost performance and no pollution. It is suitable for the extraction and separation of fat-soluble and heat-sensitive substances, and is also suitable for the fine separation of different groups, which is the preferred separation technology in the fields of pharmacy, food, flavors and fragrances, fine chemical industry, etc.,and is widely used for extracting essential oils, pigments, oleoresins, active ingredients from animal and plant raw materials and concentrating active ingredients in liquid mixtures. The purification and refining technologies are also widely used for removing harmful solvents from products.

Supercritical CO2 fluid extract

Supercritical CO2 Fluid Extraction (SCFE) is based on the relationship between the solubility of supercritical fluid and its density, that is, the effect of pressure and temperature on the solubility of supercritical fluid.
