  • 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 the first step in refining rice bran oil?
  • In industrial production, rice bran oil is mostly refined by hydration degumming, active clay decolorization, steam deacidification and deodorization, and low-temperature freezing dewaxing. The specific method is to add 2¡ë~3¡ë phosphoric acid and a proper amount of water to treat the crude rice bran oil at 90 °C for degumming.
  • 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.
  • What are the methods used to extract rice bran oil?
  • Rice bran oil is extracted by pressing or solvent extraction methods, such as supercritical carbon dioxide extraction and enzymatic extraction. There are about 15¨C20% crude oil in rice bran.
  • Why is rice bran crude oil difficult to refine?
  • The high acid value and dark color of rice bran crude oil make it difficult to refine rice oil. Nutrients are readily lost during the refining process. In addition, the production of trans-fatty acids, 3-chloropropanol ester, and other potentially harmful substances affects the quality and safety of rice oil products.
  • 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.
