Phoenix dactylifera L. type Mariami from Iran was chosen for this study to investigate the solubility of its seed oil in supercritical carbon dioxide (SC-CO2). The seed has been discovered to possess an antioxidant. The extraction method using SC-CO2 solvent was used in this study to investigate the capabilities of supercritical fluid to extract Phoenix dactylifera L. seed oil since the method is clean compared with organic solvent extraction. Solubility of Phoenix dactilyfera seeds oil in SC-CO2 was correlated using empirical density based model with the help of IBM SPSS software for significance and correlation analysis of the models. Analysis of component in the oil was done using gas chromatography equipped with mass spectrometry (GC-MS). Oleic acid revealed to be the main fatty acid in Phoenix dactylifera seed oil, followed by palmitic acid, lauric acid, ascorbyl palmitate and others.

Particles formations of ginger rhizome were successfully produced by using Rapid expansion supercritical solution (RESS). In this study, effect of extraction temperature (40,45,55 and 65 °C) and constant extraction pressure 4000 Psi were investigated on the particle size of the produced particles. Based on the different experimental conditions, the smallest particle size of ginger after processing via the RESS process was obtained at extraction temperature of 40 °C and extraction pressure, 4000 Psi. Temperature is the one factor that can affect the average particle size of the solid oil particle. The size of the ginger particles were monitored by scanning electron microscopy (SEM).
