Cannabis extraction technologies have advanced significantly, with innovations in supercritical CO2, solventless techniques, and ethanol extraction enhancing yields and product purity. Supercritical CO2 extraction remains a gold standard, offering high-purity concentrates without harmful residues, while modern systems with precise temperature and pressure control and closed-loop designs improve efficiency and environmental impact. Solventless methods like ice water extraction, dry sifting, and rosin pressing are popular for producing natural, chemical-free products, bolstered by advancements such as automated rosin presses and enhanced filtration in bubble hash machines. Freeze-drying technology has further refined extracts for edibles and tinctures by preserving delicate cannabinoid and terpene profiles. Ethanol extraction continues to lead in affordability and scalability, with innovations like vacuum-assisted and cold ethanol extraction optimizing efficiency and preserving desirable compounds while minimizing unwanted elements like chlorophyll.
