Revised Application technology decoffeination in the Food & Beverages sector


High pressure extraction as an alternative


The alternative to organic solvents is high pressure extraction with compressed gases. Particularly in the supercritical state (having both gaseous and liquid properties) some gases exhibit excellent solvent characteristics, for example:


  • High diffusion capacity
  • Low viscosity
  • Almost zero surface tension
  • High dissolving power
  • Supercritical carbon dioxide (CO2) has proven to be extremely suitable for applications in natural product extraction. The low critical temperature of 31°C allows for a particularly gentle extraction treatment of the natural products present.   

Decaffeinating coffee represents the opposite requirement: in this case, the extract is the caffeine, which is dissolved out by means of water and CO2.  


  • Dry, solvent-free products, concentrates and essences 
  • Gentle treatment of temperature sensitive substances 
  • Natural materials isolated without loss of aroma 
  • Selective material separation through variation in pressure and temperature
  • Simple recovery of the extraction medium 


Messer develops and optimises high pressure extraction plants for individual requirements.
