- This experiment studied the extraction of oleoresin from Curcuma Xanthorrizha Roxb using supercritical carbon dioxide Effects of various operation condition such as pressure, temperature, extractions time, and addition of ethanol-co-solvent into bulk carbon dioxide have been studied Solubility ofcarbon dioxide could be increased by addition of co-solvent ethanol. Temperature and pressure affect solubility ofoleoresin in carbon dioxide so that it may affect to oleoresin, and curcuminoid yield Extraction temperature and pressure were performed at 45-65 °C and 10-18 MPa, respectively. Simulation study that could describe the process of oleoresin extraction from Curcuma Xanthorhiza Roxb by supercritical carbon dioxide have been done using Shrinking Core Model.
