Solubility of <i>Phoenix dactylifera </i>Seed Oil in Supercritical Carbon Dioxide (Sc-Co₂) Using Empirical Model

Abstract

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.

Rapid Expansion Supercritical Solution (RESS) of Carbon Dioxide as a Green Technology Method for Leucaena Leucocephala Solid Oil Particle Formation

“…As shown in Fig. 3, the highest extraction yield of L.leucocephala pods sample was obtained about 0.65% at the maximum extraction condition which are pressure of 7000 psi and temperature of 60 o C. At the highest extraction pressure, the solvating power of interaction between inter-molecules and the solute is increased due to the increased of solvent density that caused by extraction pressure [16].…”

“…4, the extraction yield increased with the increased of extraction temperature, which is from 40 o C to 60 o C at constant extraction pressure. The extraction temperature influence the isomerazation and degradation of extracting yield from plant material and also the increasing of extraction temperature from 40 o C to 70 o C will be increased the percentage of extraction yield [16]. Based on previous studies from Sovilj [24], the extracted yield increase when the increasing of the extraction temperature at the fixed condition of pressure and flowrate of supercritical CO 2 .…”

“…2 due to the highest mass of solid oil particles that obtained is 0.1997 g (0.033%) at the selected extraction time of 40 minutes by comparing to other particle size, which are 300 µm and 500 µm that attained 0.1861 g (0.030%) and 0.1315 g (0.022%), respectively. According to Aris et al [16], the highest extraction yield is obtained from the smallest particle size due to the higher of mass transfer. In addition, the smallest particle size is selected as it will be increased the extraction rate because of the larger surface area [16].…”

Comparison on Oil Yield of <i>Phoenix dactylifera </i>Seed Oil Extraction by Supercritical Carbon Dioxide and Solvent Extraction Method at 50°C

“…Supercritical Carbon Dioxide (SC-CO 2 ) extraction was carried out using laboratory-scale supercritical fluid extraction system (SFT-100, USA). Carbon dioxide gas with 99.99% purity (MOX Linde Gases Sdn Bhd, Penang, Malaysia) was continuously fed into extractor with fixed solvent flow rate of 24 mL/min and regulated by automated back pressure regulator [9]…”
