  • Can dense CO2 extract rice bran oil?
  • The purpose of this study was to measure the effects of temperature, pressure, and flow rate of dense CO 2 on its ability to extract, refine, and fractionate rice bran oil. Column beds (300 g) of rice bran were extracted with dense CO 2 at a flow rate of ∼2.5 kg/h, temperatures of 0−60 °C, and pressures of 17−31 MPa over a period of 6 h.
  • What are obsolete technologies used to extract RBO from rice bran?
  • Obsolete technologies are generally used to extract RBO from rice bran, often exploiting hexane, a solvent toxic to the environment and humans . The growing demand for this oil has led companies and universities to seek for greener and safer alternative extraction technologies.
  • What is rice bran oil (RBO)?
  • One of the most common rice bran utilization is the extraction of rice bran oil (RBO). Among all vegetable oils, RBO presents a unique chemical composition rich in antioxidant compounds such as γ-oryzanol that provide several beneficial properties. RBO is generally extracted by exploiting hexane, a solvent toxic to the environment and human health.
  • How is a rice bran extractor extracted?
  • The extracted phase falls to the bottom of the separator, where it can be recovered through a valve. The extraction was performed with a constant solvent flow of 20 kg/h for 3 h, filling the extractor with 1 kg of rice bran and metal Raschig rings to promote the solid and solvent contact.
  • What is rice bran oil?
  • Bran, one of the external cereal layers, contains proteins, dietary fibers, minerals, and lipids. One of the most common rice bran utilization is the extraction of rice bran oil (RBO). Among all vegetable oils, RBO presents a unique chemical composition rich in antioxidant compounds such as γ-oryzanol that provide several beneficial properties.
  • Can supercritical carbon dioxide extract RBO?
  • The growing demand for this oil has led researchers to look for more sustainable extraction techniques. Supercritical carbon dioxide (SC-CO 2) has been successfully applied to extract oil and functional compounds from several matrices. In this work, the SC-CO 2 extraction of RBO was optimized using a Design of Experiment (DoE) on a pilot scale.
