The solubility of beta-carotene from crude palm oil using a
phase equilibrium loading recirculating high-pressure-type apparatus at temperatures of (353.2,
373.2, and 393.2) K was studied. The experimental data showed that the mole fraction solubility
of beta-carotene was 2.27.10(-2) at a temperature of 393.2 K and at pressure of 5.4 MPa. The
experimental data were compared with a set of theoretical data that was calculated using the
regular solution theory model (RSTM). The theoretical data showed that the RSTM was able to
correlate the solubility of beta-carotene from crude palm oil in carbon dioxide. The mole
fraction solubility of beta-carotene based on the RSTM was 5.30.10(-3) at temperature of 393.2 K
and at pressure of 3.3 MPa.
