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 CO2 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.
