CO2 extraction permits to obtain oily extracts from natural products at low temperatures and without using organic solvents.

Compared to cold press extraction, CO2 is specially good when high yields are required or when starting amount of oily material is not high. In these cases, cold pressing is not able to extract the oil and CO2 is the alternative.

So, CO2 extraction is widely used to obtain high value oils to be used as Food suplements, flavours, antioxidants, from vegetal materials like:

  • Seeds: brocoli, lupin, carrot, pomegranate, sesame, blackcurrant, pepper, cumin…
  • Berries: Saw pametto, raspberrie, sea buckthorn…
  • Nuts: almond, hazelnut, cashew…
  • Roots: angelica, ginger…
  • Flowers and/or leaves: Chamomile, Oregano…
