The solubility of β-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 β-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 β-carotene from crude palm oil in carbon dioxide. The mole fraction solubility of β-carotene based on the RSTM was 5.30·10−3 at temperature of 393.2 K and at pressure of 3.3 MPa.
