  • What is rice bran oil?
  • Rice bran oil (RBO) is unique among edible vegetable oils because of its unique fatty acid composition, phenolic compound (¦Ã-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.
  • What is rice bran?
  • Rice bran is obtained from outer layer of the brown (husked) rice kernel during milling. It has emerged as potential by-product from rice processing industry due to the increasing demand for rice bran oil (RBO) as healthy functional food ingredients.
  • 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 ).
  • Which bioactive peptides are used in enzymatic hydrolysis of rice bran?
  • The bioactive peptides prepared using enzymatic hydrolysis of rice bran demonstrated immune-modulatory effects along with antioxidant and anti-cancer activities. Rice bran dietary fibers, arabinoxylan and ¦Â-glucan have immune- stimulatory effect.
  • Which phenolic acid is found in rice bran?
  • Ferulic acid is the major phenolic acid, followed by p- hydroxycinnamic acid, sinapinic, gallic, protocatechuic, p -hydroxybenzoic and vanillic acid in rice bran ( Goufo and Trinade, 2014 ). RBO contains a range of fatty acids, with 47% monounsaturated, 33% polyunsaturated and 20% saturated.
