For the past decade, CO2 extraction method has been doing its fair share of rounds among the manufacturers of essential oils. High pressure coupled with low temperature is used collaboratively in an energy efficient and environment friendly process (since CO2 is produces as a by-product of fermentation and not combustion).

The CO2 extraction process creates phase changes in carbon dioxide utilizing temperature and pressure. CO2 is accepted as an excellent tunable solvent. This is due to the versatility of CO2 in creating a multitude of end products by governing temperature and pressure at the same time. These phase changes develops an environment to drop out diverging weights of constituents in the plant material. Benefits of CO2 Extraction
The best advantage of CO2 extraction is the minimal extraction time. The yield is however higher, which is an added advantage. The cost efficiency is ensured as it consumes low energy.
The CO2 that evaporates during the process has virtually no residual solvent. Under low temperatures, an ideal organic state can be achieved.
