We specialize in CO2 extracted oils and flavors. Our products can be used as food and drink additives.
Our CO2 extraction system employs simple pressurized CO2 gas; no harsh chemicals are used. CO2 changes properties with temperature and pressure.
CO2 plotted on temperature and pressure axes exhibits the following property profile:
CO2 Can Exist as a Solid, a Liquid, or a Gas
The technology we use is commonly referred to as Supercritical Fluid Extraction or CO2 SFE. It is also commonly called supercritical CO2 extraction. This is because above specific temperatures and pressures CO2 adopts ‘Supercritical’ properties where it becomes a super solvent.
For our extractions subcritical CO2, in the form of a liquid, yields the best results.
Our machine flows pressurized CO2 at controlled temperatures through botanical material. At pressure, the botanical’s essential oils are suspended in the liquid CO2.
The CO2 carrying the oil is then depressurized whereby the oil falls out of suspension and is deposited in a collection vessel. Any remaining CO2 in the collection vessel is gaseous and will dissipate resulting in an extract completely free of solvent. The clean, depressurized CO2 is then re-pressurized and recirculated through the botanical material.
Environmentally Friendly/No harsh chemicals
CO2 SFE extraction technology offers advantages over conventional extraction methods in that CO2 itself is nontoxic, inexpensive, non-flammable and non-polluting.
Lower Temperatures preserves flavors
The properties of CO2 allow us to conduct extractions at temperatures typically below 80° F. These low extraction temperatures are vital to preserving the oil’s volatile compounds responsible for flavor and aroma.
