  • What are the methods used to extract rice bran oil?
  • Rice bran oil is extracted by pressing or solvent extraction methods, such as supercritical carbon dioxide extraction and enzymatic extraction. There are about 15¨C20% crude oil in rice bran.
  • Is rice bran oil a solventless extraction method?
  • This review has highlighted that despite the efficiency in the extraction of rice bran oil, some solvents are toxic. The future direction should therefore focus on green extraction methods in order to address the need for environmental sustainability. The solventless methods or the methods that use water as a solvent are therefore encouraged.
  • What is rice bran aqueous extraction?
  • This technique facilitates the release of oil in aqueous extraction processes, while avoiding the use of or-ganic solvents. It is worth noting that the main components of plant cell walls are cellulose, hemicellulose, pectin, lignin, and protein. The oil in rice bran is accumulated in organelles, which are called lipid bodies.
  • Can organic solvent-extraction be used to produce high value rice bran oil?
  • Organic solvent-extraction is widely applied. The production of high value rice bran oil is gaining increased interest, and is the subject of the present paper. Field data from a 32 T/day pilot plant in Heilongjiang will be compared with engineering simulations.
  • Can rice bran be treated with enzymes?
  • Treating rice bran with enzymes is a new oil processing technology. The cell tissue of rice bran is hydrolyzed with protease and then oil is released to achieve the purpose of oil extraction (Hanmoungjai et al. 2001).
  • Can rice bran oil be extracted from a pilot plant?
  • The pilot-plant extraction of rice bran oil was assessed. The solvent-extraction and associated processes were simulated. Results and field data are shown to be in good agreement. Energy optimization was performed using pinch technology and gas membrane technology. Nearly 50% of energy can be saved in comparison with the original process.
