What is Supercritical CO2 Extraction And Why Does it Matter?

The ,base, of each method is a solvent, or a “substance, ordinarily a liquid, in which other materials dissolve to form a solution.” In general, the solvent being used determines the cost of each ,extraction, as well as the risk factor if any solvent is left over in the final product. Some popular methods rely on harsh solvents like butane, hexane, and propane, which cost less to use, but can ...
