The Application of Supercritical CO2 Based Technology for Curcumin Particle Processing

Article Preview

Abstract:

Supercritical CO2 is commonly used in the processing of natural products due to several advantageous factors such as inexpensiveness, moderate operating parameters and simple purification step. In the processing of phyto-pharmaceuticals, CO2 has been used mostly for extraction, purification and particle formation. This article is a review of supercritical particle formation processes applied to phenolic compounds, specifically curcumin. In summary, supercritical technologies constitute a process platform for the modification of curcumin physicochemical properties. The use of supercritical CO2 as a solute, solvent or anti-solvent in curcumin processing enabled the production of material with particle size as small as 15 nm and improved antioxidant activity.
