Extraction of rice bran oil by supercritical carbon
In this work, extraction of oil and γ-oryzanol from crushed rice bran using supercritical carbon dioxide at various CO 2 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 SCCO
Extraction of rice bran lipids with supercritical carbon dioxide (SC-CO 2) was performed. To investigate the pressure effect on extraction yield, two isobaric conditions, 7000 and 9000 psi, were selected. A Soxhlet extraction with hexane (modified AOCS method Aa 4–38; 4 h at 69°C) was also conducted and used as the comparison basis. Rice
