In this study, the oil from Calophyllum inophyllum seeds was extracted using ultrasonic-assisted extraction (UAE) technique. Patricelli’s model was used to evaluate the kinetics of oil extraction process in which this model describes extraction in two stages namely rapid washing stage followed by slow diffusion stage. The model parameters were calculated using the experimental data. A good agreement was observed between the experimental and simulated oil yield in all experiments (R20.974), indicating that Patricelli’s model was adequate to describe the C. inophyllum seeds oil extraction process. In addition, the influence of three extraction parameters, namely ultrasonic power, extraction temperature and liquid to solid (L/S) ratio on oil yield were studied. It was found that the oil yield increased with increasing ultrasonic power, extraction temperature as well as L/S ratio.
