1. The influence of extraction methods on composition and antioxidant properties of rice bran oil
AbstractThe current study was employed to assess the influence of the different extraction methods on total tocols, γ-oryzanol content, and antioxidant properties of Chiang Mai Black rice, Mali Red rice, and Suphanburi-1 Brown rice bran oil. Rice bran oil (RBO) was extracted by Hexane, Hot pressed, Cold pressed, and Supercritical Fluid Extraction (SFe) meth

3. Supercritical fluid extraction (SFE) of rice bran oil to obtain fractions enriched with tocopherols and tocotrienols
Parboiled rice bran oil was obtained with supercritical CO2 at temperatures and pressures varying from 25 to 60ºC and from 150 to 250 bar, respectively. This study was divided into two different parts: initially, the experiments were carried out with one separation step. In the second part, experiments were performed with two separators in series. The tempe

4. Desacidification of the oil of bran of rice for extration liquid-liquid. / Desacidificação do oleo de farelo de arroz por extração liquido-liquido.
The objective of this work was to evaluate the rice bran oil deacidification process by liquid-liquid extraction (LLE), in a continuous equipment, using aqueous ethanol as solvent. The alternative process was evaluated in terms of: ability to extract the free fatty acids; ability to minimize the neutral oil loss and, ability to preserve nutraceutical compoun
