Carbon dioxide extraction

Carbon dioxide extraction is a method used to pull specific compounds, like flavors or oils, from plants using carbon dioxide in a supercritical state—when it's between a gas and liquid. Under this condition, CO₂ acts as a selective solvent, efficiently dissolving desired substances without using harsh chemicals. Once the extraction is complete, lowering the pressure allows the CO₂ to revert to gas and leaving the extracted compounds behind. This process is valued for its purity, safety, and ability to preserve delicate flavors and bioactive compounds, making it popular in food, supplement, and pharmaceutical industries.
