  • What technologies are used in rice bran oil extraction?
  • New combined technologies have emerged to improve the efficiency and quality of rice bran oil. These include enzyme-assisted extraction, ultrasound-assisted water extraction, supercritical and subcritical CO 2 extraction, microwave-assisted extraction, and subcritical fluid technology. All these have broad application prospects . 5.1.1.
  • How is rice bran oil extracted?
  • Rice bran oil (RBO) can be extracted chemically using solvent or mechanically by hydrolytic pressing. Solvent extraction covers a wide range of techniques, including traditional solvent extraction, ultrasound assisted extraction, supercritical fluid extraction, and enzyme assisted extraction (Fraterrigo Garofalo et al., 2021a).
  • What is enzyme assisted extraction of rice bran oil?
  • Enzyme assisted extraction of rice bran oil and their corresponding yields. The advantages of enzyme assisted extraction technique compared to conventional solvent extraction methods includes reduced time of extraction, minimized solvent usage and increased yield and quality of product.
  • What is the extraction rate of rice bran oil?
  • The extraction rate of rice bran oil was close to that of Soxhlet extraction when the ultrasonic-assisted extraction technology was at pH 12, the temperature was 45 °C, the stirring speed was 800 r/min, the stirring time was 15 min, the ultrasonic treatment time was 70 min, and the ultrasonic treatment temperature was 25 °C .
  • 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.
  • 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 ¦Ã-oryzanol to be obtained and show comparable yields with the extraction methods that employ hexane.
