Supercritical CO2 extraction is the standard extraction method for the food, dry cleaning and herbal supplement industries. It is a common food additive as well.
In fact, CO2 is used to produce carbonated soft drinks, in the removal of caffeine from coffee beans in order to make decaffeinated coffee, as an environmentally friendly solvent for dry cleaning, and as an extraction solvent when producing essential oils. Supercritical CO2 is also common when pesticides and metals are extracted from agricultural crops.
“The CO2 extraction process allows compounds to be extracted with little damage and low toxicity.” it utilizes a high pressure vessel containing cannabis.
Supercritical CO2 is inserted into the vessel, and pumped through a filter where it is separated from the plant matter once the pressure is released. Next, the supercritical CO2 evaporates and is dissolved into the cannabinoids.
