Abstract

Among vegetable oils, rice bran oil has been considered to be one of the most valuable and healthy oil because it contains many nutraceutical components. In this work, extraction of oil and γ-oryzanol from crushed rice bran using supercritical carbon dioxide at various CO₂ flow rate (1-9 ml/min), temperatures (40-80 C) and pressures (20-40 MPa) was investigated. The experimental extraction behavior was explained using two simple models of thermodynamic model and simple kinetic model. In addition, solubility data of rice bran oil in SCCO₂ showed a good agreement with the values of the correlation of Chrastil model. The effect of extraction temperature and pressure on the γ-oryzanol recovery was studied.
