Subcritical extraction is a new advanced technology suitable for extracting natural extracts including Curcumin and Turmeric oil.

Why Choose Subcritical Extraction Process?

Subcritical Extraction Technology may be referred to as low temperature pressurized (0.3-0.8 MPa) fluid extraction process. This process requires the use of an extracting agent that exists in different states when the pressure is varied from normal pressure to very high pressure.

  • The extracting agent exists in the fluid state under pressurized condition;
  • Under normal pressure, it is gaseous;
The extraction solvent molecular ability to diffuse is greatly increased with the existence of under subcritical pressure condition. Which implies?
  •   Increased transfer rate
  •   Significant improvement for the extraction solvent to dissolve
  •   Enhanced permeability
Therefore, Subcritical extraction like Supercritical extraction produces high grade oil products despite the fact that the former uses much lower extraction pressure. Subsequently, the equipment price is thus highly reduced making it a better fit for the scale production in the industry in addition to the increased transfer rate, permeability and ability to dissolve.
