Understanding CO2 Extraction
What is CO2 Extraction?
CO2 extraction utilizes supercritical carbon dioxide (CO2) as a solvent to extract essential oils and other compounds from plant materials. By applying high pressure and temperature, CO2 becomes supercritical, exhibiting properties of both gases and liquids. This makes it an efficient solvent for extracting a wide range of compounds without leaving harmful residues.
Benefits of CO2 Extraction
- Safety: CO2 is non-toxic and safe for food and pharmaceutical applications.
- Eco-Friendly: Unlike traditional solvents, CO2 extraction minimizes environmental impact.
- Preserves Quality: The process preserves the integrity of the extracted compounds, ensuring high-quality results.
- Versatility: Suitable for extracting various substances from different plant materials.
Types of CO2 Extraction Machines
Tabletop CO2 Extractors
Tabletop CO2 extractors, like the SuperC™ from OCO Labs, are perfect for home use. They are compact, user-friendly, and designed for small batch production.
