CO2 Extraction
CO2 extraction uses supercritical carbon dioxide as a solvent to extract essential oils, producing high-quality oils with a broad range of aromatic compounds.
History
CO2 extraction is a relatively new method, praised for producing purer, more aromatic oils.
Process
CO2 is pressurized until it becomes "supercritical," a state between a gas and a liquid. This supercritical CO2 is passed through the plant material to extract the oils.
Required Equipment
- CO2 Extractor
- Separator
Extraction Details
- Extraction Time: 4-5 hours
- Raw Material: 1000 grams of plant material
- Yield: 2-4% of essential oil (20-40ml per 1000g)
- Temperature Range: 31-33°C
- Water Ratio: N/A
Tips for Best Results
- This method is ideal for extracting oils with high sensitivity to heat.
- Use CO2 extraction for high-quality oils with a wide range of aromatic compounds.
