dc.description.abstractThis contribution provides basic data for developing an extraction process for carotenoid compounds in terrestrial and marine plants with supercritical CO2 (SC-CO2). Specifically, the solubility (y(2), molar fraction) of lycopene and astaxanthin was measured in SC-CO2 as a function of temperature (313 K <= T <= 333 K) and pressure (10 MPa <= P <= 42 MPa). Experimental data were correlated using a density-based model valid for a solvent density above 330kg/m3. Based on this model and the best-fit model parameters, the solubility of lycopene in SC-CO2 at 313 K and 30 MPa (y(2) = 0.40 x 10(-6)) was within a wide range of experimental values for the solubility of beta-carotene in CO2 under same conditions (0.20 x 10(-6) <= y(2) <= 0.50 x 10-6). The interpolated solubility of astaxanthin in SC-CO2 at 313 K and 30 MPa was slightly smaller (y(2) = 0.19 x 10(-6)) than the one of lycopene, as expected for a slightly heavier and more polar solute. There was a larger increase in solubility of both lycopene and astaxanthin by increasing the temperature from 313 to 333 K at a constant pressure of 30 MPa (2.8-5.1 times) than by increasing the pressure from 30 to 50 MPa at a constant temperature of 313 K (1.3-1.6 times), which was consistent with the trend in literature for the solubility of beta-carotene in SC-CO2.
