Why Supercritical CO2 Extraction is Gaining Popularity

  •   What is Supercritical CO2 Extraction ? Supercritical fluid extraction (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids as a solvent. The most commonly used supercritical fluid is carbon dioxide, but other solvents, such as ethanol, can be utilized as well. A supercritical extraction method is distinct from a subcritical extraction, as it extracts more of the wanted components and fewer of the undesired ones. The Response Surface Methodology Regression Analysis can be used to study the Effects of Variables on Supercritical Carbon Dioxide Extraction.

  •   Supercritical carbon dioxide extraction is a new separation technology developed in the 1970s. The principle is to separate a supercritical fluid from a solid or liquid mixture and then purify or use the separated material as a solvent. A supercritical fluid (SCF) is a gas with special physicochemical properties that can expand to 20-100 times its original volume at a certain temperature and pressure, i.e. a supercritical fluid. When certain parameters such as temperature, pressure, and density are met, the components of the fluid are separated into different forms.

  •   Supercritical CO2 extraction is a green extraction technology that uses the supercritical state of CO2 to dissolve certain substances at a critical temperature and pressure and to extract the active ingredients from various natural substances. This technology is a new type of green extraction and separation technology, using CO2 as the medium, without solvents, without destroying the material structure of the raw material, and at the same time can recycle CO2, with high extraction efficiency, low solvent consumption, low cost, and low energy consumption, suitable for the extraction of active ingredients in traditional Chinese medicine and natural products. Supercritical CO2 extraction technology has the characteristics of low operating temperature, high pressure (more than 100 MPa), good selectivity (strong CO2 solubility), low energy consumption (energy consumption is only 1/3 of traditional solvent extraction), and short operating time.

    Supercritical carbon dioxide extraction is a new type of extraction technology that uses supercritical fluids (SFE) as an extraction medium to separate, purify and refine trace substances in mixtures in a supercritical state. sFE is a non-toxic, non-polluting, safe, and effective separation technique that can obtain better extraction results with less solvent than organic solvents. As no toxic or hazardous substances are produced during SFE operations, it can be used as a method for extracting active ingredients as well as for environmental protection. SFE technology can be widely used in pharmaceuticals, chemicals, food, cosmetics, food additives, environmental protection, and other fields to separate and purify the extracted substances and also to recycle the gaseous products or use them directly in the next chemical reaction.
