supercritical fluid extraction of β-carotene from crude palm oil using co2 in a bubbler extractor: mass transfer study

in this study, the diffusivity and volumetric mass transfer coefficients for the extraction of β-carotene from crude palm oil using co2 solvent in supercritical fluid were determined in the pressure range of 7.5-17.5 mpa and temperature range of 80-120 ºc. for this purpose, a statistical method was applied in order to minimize the number of experiments required. the volumetric mass transfer coe...

Mutual Solubility Study in Supercritical Fluid Extraction of Tocopherols from Crude Palm Oil Using CO2 Solvent

In this article, the mutual solubility of tocopherols from crude palm oil was studied using carbon dioxide as a solvent at the temperatures of 80, 100 and 120 °C. Each sample from the phase equilibrium unit contained two parts. The liquid part was analyzed by gas chromatography (GC) in order to measure the tocopherol composition and, on the other hand, the vapor phase was conducted in an expans...

In Vitro Antioxidative Evaluation of α- and β-Carotene, Isolated from Crude Palm Oil

The present work describes the isolation of α - and β -carotene from crude palm oil and their antioxidant potential in an in vitro model. Pure product was isolated by the method adopted. Antioxidant activities of the isolated α - and β -carotene were analyzed in five different concentrations of 0.001, 0.005, 0.01, 0.05, and 0.1% (w/v). From the several assays conducted, an observation was made ...

Applications of supercritical fluid extraction (SFE) of palm oil and oil from natural sources.

Supercritical fluid extraction (SFE), which has received much interest in its use and further development for industrial applications, is a method that offers some advantages over conventional methods, especially for the palm oil industry. SC-CO₂ refers to supercritical fluid extraction (SFE) that uses carbon dioxide (CO₂) as a solvent which is a nontoxic, inexpensive, nonflammable, and nonpoll...

Phase Equilibrium Study of Triacylglycerols from Crude Palm Oil Using CO2

Two-phase equilibrium data was measured for carbon dioxide with triacylglycerols from crude palm oil using a phase equilibrium loading re-circulating high-pressure type apparatus at various pressures and at temperatures of 80, 100 and 120°C. According to this research, it concluded that the highest extraction in term of vapor phase was carried out at a middle pressure (P=5.4 MPa) and at tempera...
