Extraction and utilization of rice bran oil: A review

A short review of green extraction technologies

  • How is rice bran oil extracted?
  • There are about 15–20% crude oil in rice bran; normally, the rice bran oil is extracted by pressing or solvent extraction methods, such as supercritical carbon dioxide extraction and enzymatic extraction, and then refined by decolorization, deodorization, or other processes.
  • What is rice bran oil (RBO)?
  • This lipidic fraction can be extracted to obtain rice bran oil (RBO), a high value-added product with unique health properties as a result of its high concentration in γ-oryzanol, a powerful antioxidant mixture of bioactive molecules.
  • Can -oryzanol be extracted from rice bran oil?
  • All the here reported green extraction techniques allow a high-quality rice bran oil and high concentrations of γ-oryzanol to be obtained and show comparable yields with the extraction methods that employ hexane.
  • 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.
