  • What is rice bran oil?
  • Rice bran oil (RBO) is unique among edible vegetable oils because of its unique fatty acid composition, phenolic compound (γ-oryzanol, ferulic acid) and vitamin E (tocopherol and tocotrienol). It has become a great choice of cooking oil because of its very high burning point, neutral taste and delicate flavour.
  • How to make rice bran RBO?
  • Cold pressing uses mechanical screw press with mild heating followed by filtration to get clean RBO. Pre-treatment of rice bran with low temperature before cold pressing can produce RBO with superior quality ( Srikaeo and Pradit, 2011 ). A combination of short cooking time and cold pressing is more effective and efficient.
  • Should rice bran be stabilized after production?
  • It is advised to stabilize rice bran or RBO immediately upon production. High FFA results in high refining loss, therefore, it is beneficial to have FFA level of less than 5% in the crude RBO, and exceeding amount of FFA (> 10%) is unfit for human consumption ( Orthoefer and Eastman, 2005 ).
  • How to stabilize rice bran fractions in microwave?
  • Lavanya et al. (2019) stabilized rice bran fractions by microwave heating continuously at 850, 925 and 1 000 W and 3.0, 4.5 and 6.0 min. They concluded that microwave heating at 925 W for 3.0 min is the suitable condition for RBO extraction and stabilization.
