Post-Extraction Considerations Once the oil is extracted, the process is far from over. Furthermore, the geographic origin, or terroir, plays a critical role.
Comparing Extraction Methods: CO2, Expression, and Beyond
Another sophisticated technique, CO2 extraction, uses supercritical carbon dioxide as a solvent. This commitment to integrity is what separates genuine therapeutic-grade oils from inexpensive imitations.
When pressurized CO2 passes through the plant material, it acts as a solvent, pulling out the essential oils. Trained professionals assess the oil using organoleptic testing, evaluating its color, viscosity, and, most importantly, its aroma.
Comparing Extraction Methods CO2, Expression, and Beyond
The method chosen is never arbitrary; it is dictated by the plant's physical structure, the chemistry of the desired compound, and the intended application of the final product. Alternatively, expression, also known as cold pressing, is a mechanical process primarily used for citrus peels like oranges and lemons.
