Supercritical fluid extraction (SFE) is a technique that adds a supercritical fluid of an extraction medium to a sample containing a constituent targeted for extraction, using the difference in solubility compared with the extraction medium to carry out the extraction procedure. Using supercritical carbon dioxide as an extraction medium has many advantages and is used in a variety of fields. Extraction by means of supercritical carbon dioxide can be expected to improve efficiency, including shorter extraction times and simplified procedures when compared with extraction techniques that employ organic solvents. In addition, it offers easier solvent elimination and concentration procedures. Since its critical temperature is a low 31ºC or so, it enables extraction at a near-room temperature state or in a carbon dioxide atmosphere devoid of oxygen. This makes it a technique that is ideal for materials that exhibit temperature instability or constituents that are susceptible to oxidation. Furthermore, it has received recent attention as an environmentally friendly extraction technique that does not use hazardous organic solvents, as has been advocated by the green chemistry movement in recent years.
Applications for SFE include the extraction of active constituents, including various flavors and medicinal constituents from natural products, docosahexaenoic acid (DHA), advanced unsaturated fatty acids and fatty esters such as eicosapentaenoic acid (EPA), fat-soluble vitamins, and pharmaceuticals. Other applications include the elimination of unwanted constituents, such as decaffeination and desolvation within tablets. It also can be applied to the preprocessing of analysis samples, including HPLC and GC.
