Unlock the possibilities of your natural products with Supercritical Fluid Extraction (SFE)
Supercritical CO2 Extraction is a technology in which carbon dioxide, put beyond its critical point (73 bars and 30°C), becomes a supercritical fluid with special properties. The extraction carried out at a low temperature preserves the natural profile identity of the raw material.
Supercritical CO2 Extraction is a technology in which carbon dioxide, put beyond its critical point (73 bars and 30°C), becomes a supercritical fluid with special properties. The extraction carried out at a low temperature preserves the natural profile identity of the raw material.
SFE uses supercritical fluid as an extractant to separate a component (extract) from a mixture (matrix). Carbon dioxide (CO2) is the most commonly used supercritical fluid.
The principle of supercritical fluid extraction and separation process is that supercritical fluid has a special dissolution effect on fatty acids, vegetable bases, ethers, ketones, glycerides, etc., and is carried out by using the relationship between the solubility of supercritical fluid and its density, that is, by using the influence of pressure and temperature on the solubility of supercritical fluid.

In the supercritical state, the supercritical fluid is contacted with the substance to be separated to selectively extract the components of polarity, boiling point and molecular weight. Of course, the extracts obtained corresponding to each pressure range cannot be single, but the conditions can be controlled to obtain the best proportion of mixed components, and then the supercritical fluid can be changed into ordinary gas by means of pressure reduction and temperature rise, and the extracted substances can be completely or basically separated out, so as to achieve the purpose of separation and purification.Therefore, the supercritical fluid extraction process is a combination of extraction and separation.
