Extraction of passion fruit seed oil using supercritical CO2: A study of mass transfer and rheological property by bayesian inference

Abstract

The extraction of oil from passion fruit seeds using supercritical CO 2was studied. Experimental data were obtained for extraction conducted at 15, 20 and 25 MPa; at temperatures of 40 and 50 °C with CO 2flow rates of 1.5 and 3.0 mL min-1. An increase in the pressure, temperature and CO2flow rate increased the yield. The maximum extraction yield obtained was 18.5%. The mass transfer coefficients for passion fruit oil were found to be 8.496 3 10-5 s-1 at 25 MPa, 50 °C and 3 mL s-1CO2flow rate. Dilatant fluid behavior was observed in all tests of the rheological study.
