• What is edible oil refining?
  • Edible oil refining is a set of processes or treatments necessary to turn vegetable raw oil into edible oil .
  • What is the industrial processing of vegetable oils?
  • The industrial processing of vegetable oils has become increasingly standardized based on national or international standards, and high-capacity production of extraction and refining has been realized .
  • What is raw vegetable oil?
  • Raw vegetable oil, obtained from seeds by pressing, solvent extraction, contains free fatty acids and other components such as phospholipids, waxes, peroxides, aldehydes, and ketones, which contribute to undesirable flavor, odor, and appearance; [ 1] for these reasons, all the oil has to be refined. [ 2]
  • What is vegetable oil used for?
  • Vegetable oil is rich in triglycerides and contains fatty acids and micronutrients (tocopherols, phospholipids, sterols, carotenoids, etc.) . It has been widely used in the cooking, food, pharmaceutical and cosmetics industries, among others . The annual growth rate of global demand for vegetable oil was 5.14% from 2020 to 2025 .
  • How to improve the quality of vegetable oil?
  • It is worth noting that some beneficial components are also removed, such as carotenoids (mainly including ¦Á- and ¦Â-carotene) and tocopherols (such as tocols and tocotrienols) . Thus, a moderate, focused refining process is very important to improve the quality of vegetable oil.
  • What extraction techniques are used for oil recovery from oilseeds?
  • Various extraction techniques and importance of solvent choice for oil recovery from oilseed are discussed. Mechanical, aqueous, enzymatic, supercritical CO 2 and hexane extraction of important oilseeds are reviewed. Recent developments in crude oil refining processes are also included in this chapter.
