• What is the extraction yield of rice bran oil (RBO)?
  • The extraction yield of ethanol was 13.6%, 3.5%, and 11%, respectively, for the Teti, Luna, and Ariete varieties. Rice bran oil (RBO) extraction yields (%) at different temperatures, solvents, and solvent-to-sample ratios. Results are expressed in mean ¡À SD.
  • How is RBO extracted 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 [ 6 ]. The growing demand for this oil has led companies and universities to seek for greener and safer alternative extraction technologies.
  • 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.
  • How do you calculate the yield and recovery of rice bran?
  • The yield was calculated as the ratio between the mass of extracted oil and the mass of initial rice bran, and the recovery was calculated as the ratio between the mass of extracted oil and the total oil content determined by the Soxhlet method (0.1544 g oil ¡¤g bran?1 ).
  • Is compressed LPG better than supercritical Co for rice bran oil extraction?
  • Considering the slight difference in the yield and antioxidant activities of extracts between the solvents, compressed LPG is a more promising solvent than supercritical CO for extraction of rice bran oil, since the extraction period can be considerably reduced while lowering the energy required for solvent recompression. 1. Introduction
  • 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 ¦Ã-oryzanol that provide several beneficial properties.
