  • How is rice bran oil extracted?
  • Table 3. New rice bran oil extraction technology. Mechanical pressing is a conventional extraction technique that does not involve heat treatment or any organic solvent and is less expensive than solvent extraction.
  • Does delayed stabilization affect the quality of rice bran oil?
  • Research has found that a delayed stabilization treatment of rice bran seriously affects the overall quality of rice bran oil. Compared with traditional solvent extraction, the new extraction technologies have improved the yield and nutritional value of rice bran oil, but most of them are still in the research stage.
  • 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 do enzymes improve the extraction rate of rice bran oil?
  • The addition of specific enzymes (cellulase, pectinase, and protease) to destroy the cell wall and release active substances significantly improves the extraction rate. Most of the properties are the same as those of the solvent extraction of rice bran oil, but the content of colored substances is lower and the acidity (FFA) is higher .
  • What is rice bran oil used for?
  • One of the most common utilizations of rice bran is the extraction of rice bran oil. Among all vegetable oils, rice bran oil is rich in antioxidant compounds that provide several beneficial properties . The lipids are extracted into the pale yellow and translucent rice bran oil, which has a slightly nutty taste.
  • 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 .
