  • What are the steps in a rice bran oil refining process?
  • The steps in the process of refining rice bran oil are given in Fig. 14.1. The first step in the refining process with crude rice bran oil is usually dewaxing or winterizing. However, for other vegetable oils, the dewaxing step can be done at different times in the refining process.
  • How is rice bran oil refined?
  • After the extraction, the crude rice bran oil is often refined in order to improve its quality and commercial value. The fundamental steps of the refining process include dewaxing, degumming, neutralization of the free fatty acids, bleaching, and steam deodorization.
  • What is deacidification of rice bran oil?
  • Deacidification is the process of removing free fatty acids from crude rice bran oil. This process can be achieved through various methods such as alkali refining, distillation, mixing, re-esterification, and extraction. Among these, alkali refining has comprehensive effects like deacidification and decolorization, but it results in higher refining loss.
  • What is rice bran oil production?
  • Rice Bran Oil production is an interesting journey that starts with the humble rice grain. Here's how it unfolds: The journey to making Rice Bran Oil starts in a rice mill.
  • What is rice bran oil (RBO)?
  • Rice bran oil (RBO) is considered to be a superior quality oil as it has a balanced fatty acid profile, and it contains a number of minor components with proven nutritional benefits such as ¦Ã-oryzanol, tocotrienol, tocopherol, and squalene (Houston, 1972).
  • Why is sodium hydroxide important in rice bran oil refining?
  • In the refining of rice bran oil, which is prone to hydrolytic rancidity and high free fatty acid levels, an amount of base like sodium hydroxide is used to neutralize the free fatty acids in the crude oil. This is a common method called chemical refining or deacidification.
