CO2 has been historically used to extract many different kinds of biomass. The most famous and successful industrial process for CO2 extraction is the coffee decaffeination process.
However there are many other essential oil extracts that are used in the supplements industry that utilize CO2 extraction. Another good example of this is found in hops. Hops are used to brew beer and add flavor to beer.
CO2 extraction is used to extract the essential bitter flavor from the hops so that the flavors can be blended and preserved. Learn more about supercritical CO2 extraction process at extraktLAB.
