Abstract
This disclosure provides methods and systems for the supercritical fluid extraction of cannabinoids from cannabis. The supercritical fluid extraction of cannabinoids is performed with carbon dioxide (CO) balanced with one or more hydrocarbons, such as propane, propene, and propadiene. As demonstrated, the extraction can be carried out at maximum efficiency and energy savings while keeping the wax formation at minimum by lowering temperature. The methods and systems disclosed herein reduce the production time and safety/environmental hazards and are suitable for proper and safe extraction in non-GMP and GMP environments.
