CO2 - Extraction Technology - The Smart Solution

Carbon dioxide, when under pressure, is a safe solvent that does not leave any residues behind after usage. Supercritical CO2 is a modern and welcomed substitute for traditional organic solvents.

Selective and Gentle Technology
By varying the gas density and pressure or by adding ethanol as a co-solvent, we are able to adapt the dissolving power and the selectivity towards the raw material. We use high purity natural carbon dioxide with a volcanic origin from our region with a pressure up to 500 bar above the critical temperature of 31°C (88°F). This gentle process extracts sensitive active substances, flavours and fragrances under the exclusion of oxygen.

Flexible Method for Extraordinary Quality
Using a single method, we can obtain from one raw material different extracts. In particular, we differentiate between selective extracts as a replacement for steam distillates and total extracts, which are comparable to hexane extracts.
Supercritical CO
2 extraction leads to an extraordinary quality in which sensitive components are preserved. Compared with products using other manufacturing processes, our CO2 extracts impress with their natural flavour, a more fresh and authentic scent and a higher active ingredient content.

State- of- the- Art Equipment - Tailor-Made Solutions for your Requirements
We run several extraction machines on a laboratory, pilot and production scale. Their capacity ranges from a few kilograms to several tons of input material per day with a total of about 1400 tons of botanical raw material per year. In addition to solid material, we also extract and fractionate liquids.
The FLAVEX extraction machines represent the latest state-of-the-art and are constantly being optimized, maintained regularly and reviewed by supervisory authorities. The plants are equipped with the most modern control technology and this ensures a reliable extract production and reproducible results.
