The latest in biotech extraction technology
At room temperature (critical temperature and pressure), carbon dioxide is a colorless, odorless and inert gas. However, when critical pressure (74atm, or 74 bar atmospheric pressure) and critical temperature (31°C) levels are exceeded, carbon dioxide takes on the highly solvent and highly permeable features of a superfluid, meaning that it can dissolve and separate a target material without initiating any chemical reaction. This helps to keep the active elements of the extracted material fully intact. Carbon dioxide is volatile under critical temperature and pressure conditions, thereby leaving no solvent residues. The above features make SFE the world’s most advanced extraction method at present.
Advantages of SFE
1. No heat damage—extraction at critical temperature (31°C) keeps active biological elements intact
2. Small extracted molecules (10-6 μm) increase absorptivity by 20-50 times
3. Carbon dioxide solvent is highly stable, and therefore does not initiate any chemical reactions or cause qualitative damage
4. No organic solvent residues—extract is up to 99.9% pure
5. Can effectively extract required material and is most advanced extraction technology
