Abstract

The solubility of Black Pepper Oil (BPO) was measured in Supercritical Carbon Dioxide (SC-CO 2 ). The temperatures and pressures of the extraction were chosen in the range of 313 – 333K and 100 - 300 bars, respectively. The solubilities attained ranged between 0.27 x 10 -5 to 2.88 x 10 -5 g extract/g CO 2 . 5 different empirical models were selected to predict the solubility of BPO in SC-CO 2 . Among the 5 empirical models, Belghait model resulted in the lowest but best absolute average relative deviation (AARD) of 14.90%.
