CO2 extraction

CO2 extraction uses carbon dioxide in its supercritical state to remove cannabis oils. CO2’s properties allow it to strip and dissolve trichomes without damaging terpenes or cannabinoids. The CO2 converts back to gas and is purged after extraction. A variety of concentrates can be produced via CO2 extraction while retaining strain-specific profiles. “CO2 extraction results in pure, strain-specific concentrates that preserve terpenes.” CO2 under pressure becomes a liquid that pulls desired components from cannabis. It washes over the material, stripping the oils. Unlike butane, CO2 won’t harm cannabinoids or terpenes when under controlled conditions. The supercritical CO2 has solvating properties but converts back to a gas. No residue is left behind after purging. The tunable process allows isolating specific compounds. A range of concentrates can be produced with CO2 extraction while retaining strain profiles. Because it pulls only slightly targeted components, CO2 oil has a clean flavor representative of the strain.
