|The particular CO2 (carbon dioxide) extraction approach to essential oils is usually called CO2 extraction or supercritical abbreviation. In other words, CO2 extraction is extracted by pressurized carbon dioxide until it becomes a crucial point in liquid say. The liquid carbon dioxide then acts like a solvent to obtain healthy plant matter and unstable oil content and dissolve the co2 in the liquid. After that, the CO 2 is brought returning to natural pressurization, the co2 evaporates back to it has the gaseous state and what remains will be the resulting oily substance.
This set of extraction methods using "high pressure and low temperature" began within the 1980s. Its instruments and equipment are very complicated and expensive, plus its essential oils are generally labeled "CO2 Extraction". This extraction method is carried out in a closed reaction tank inside the whole process, and the time required is very simple, as long as a couple of minutes (the distillation method requires no less than 1 hour).
Weighed against the solvent extraction approach, this extraction method won't have any solvent deposit.
Carbon dioxide extracts ordinarily smell thicker than distilled vital oils and often smell closer to natural turf. Carbon dioxide extract is said to contain more components than those extracted on the same plant using water distillation. This seems to make sense, because carbon dioxide extracts are frequently thicker oils and often apparently have a more thorough aroma.
This method is really a highly specialized extraction technique. Due to the volatilization belonging to the solvent, the essential oil has no solvent impurities plus the separation is relatively in depth. The extracted molecules may be larger than those extracted by distillation. There is a situation that needs to be explained. The distillation method uses steam to draw out aromatic molecules, but larger molecules can not be extracted, such as your diterpene molecules in clary sage. This is already the limit, that is certainly to say 20 It's rarely seen that terpenes along with three carbon atoms will be extracted by distillation.
