Thus, the difference between traditional distillation and supercritical extraction is that instead of heated water or steam, CO2 is used as a solvent in the latter method. The supercritical extraction process operates at temperatures between 95 to 100 degrees F whereas steam distillation operates at temperatures between 140 to 212 degrees F.

Most often we hear about supercritical CO2 extractions, but that’s actually only one method of CO2 extraction. You can also perform subcritical CO2 extractions, and ‘mid-critical’ extractions, a general range between subcritical and supercritical. Subcritical (low temp, low pressure) CO2 extractions take more time and produce much smaller yields than supercritical, but they retain the essential oils, …
