• What is conventional deodorization for refining vegetable oil?
  • Conventional deodorization for refining vegetable oil involves evaporating volatile molecules by applying high temperatures (240¨C260 ¡ãC) for 2¨C3 h. It inevitably leads to a degradation of the refined oil quality. The chief volatile compounds from the conventional deodorization process were hydrocarbons, which are not the odor source of the oil.
  • What is soybean oil (SBO)?
  • Soybean oil SBO is a vegetable oil extracted from soybean seeds. It is one of the most widely consumed cooking oils and the second most consumed vegetable oil 1. As a drying oil, processed SBO is also used as a base for printing inks and oil paints.
  • Can vacuum pressure be used in vegetable oil refining?
  • In addition, many new or emerging technologies based on the use of vacuum pressure are still under development to master, at an industrial scale, the refining operation of vegetable oil. These technologies are generally a succession of unit processes of degumming, neutralization, bleaching, and deodorization (Erickson, 1995).
  • What is the role of vegetable oil degumming process in refining edible oil?
  • Scientific Reports 14, Article number: 4064 (2024) Cite this article The vegetable oil degumming process plays a critical role in refining edible oil. Phospholipids (PL) removal from crude extracted soybean oil (SBO) by the enzymatic degumming process has been investigated in this work.
  • What is a chemical refining method?
  • The old chemical refining method was a caustic treatment for removing all PL and free fatty acids from oils. This step transforms the oil’s FFA into the soap to help produce an emulsion to remove the NHP. The soap emulsion and hydratable PL trap massive oil in the separation step. As a result, this method is not recommended economically.
  • What is processed soybean oil used for?
  • As a drying oil, processed SBO is also used as a base for printing inks and oil paints. Soybean oil was produced worldwide, constituting about half of edible vegetable oil and thirty percent of all fats and oils produced, including animal fats and oils derived from tropical plants 2.
