Abstract

Optimization, kinetics, and thermodynamics of calabash seed oil extraction (CSOE) were studied. Experimental design of the extraction process was done with response surface methodology (RSM), varying extraction parameters such temperature, time, and solvent/solid ratio. Oil extraction was carried out using Randall/Soxtec/hexane extraction-submersion method. Equally, numerical optimization tool (NOT) of RSM was employed for oil extraction optimization, while the mass transfer model and Van’t Hoff Equations were adopted to respectively evaluate the kinetics and thermodynamics of CSOE. Oil was characterized using standard methods. The extraction parameters have significant effect on the oil yield, and quadratic model was selected as the model that best fit the experimental data with p-value of 0.0001 (<0.050).
