  • 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 are the technologies of rice bran oil?
  • The processing technologies of rice bran oil include degumming, deacidification, dewaxing, etc.. These technologies help refine the oil and maintain its bioactive compounds.
  • What are the initial refining processes for rice bran oil?
  • The crude rice bran oil must go through a series of refining processes before it can meet the requirements of the standard of edible oil; those refining processes include degumming, decolorizing, and deodorizing.
  • What is the oleic acid value of rice bran oil?
  • After alkali refining, the oleic acid value of rice bran oil was reduced to 0.23 mg/g. Liu (2005) also showed that the extraction method has a good effect on deacidification, reducing the acid value from 31.02 to 4.52 mg/g at the ratio of oil to solvent (95% ethanol) of 1:1.8.
  • How many refined products are produced in Saudi Arabia?
  • In 2018, Saudi Arabia produced 1,028.3 MMb of refined products. This represented a 1.9% fall from 2017. Diesel was the most refined product at 392 MMbd, followed by gasoline and fuel oil at 199 MMb. Oil refinery throughput reached 2.7 MMb/d in 2018, which accounted for 3% of global refinery throughput and 47% of all GCC oil refinery throughput.
