• 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.
  • Why does soybean oil quality vary by origin?
  • Soybean oil quality varies by origin. These variations are due to the geographic location where the whole soybeans were grown, storage conditions and handling prior to processing. Variations in the quality of CDSBO can lead to a longer, more costly refining process, while simultaneously lowering refining yields.
  • 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 physical & chemical refining?
  • Physical and chemical refining comes from the process technology that removes the FFA -free fatty acids responsible for the oil’s acidity. Physical refining is a process distillation of the FFA in the final deodorization refining step compared to the boiling point of the triglyceride oil.
  • 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.
  • What is crude degummed soybean oil (cdsbo)?
  • Crude degummed soybean oil (CDSBO) must be refined to produce high-quality soybean oil that is suitable for human use and many industrial uses. The traditional method to refine CDSBO is called caustic refining. This method uses a chemical process to refine CDSBO and produce refined, bleached and deodorized soybean oil (RBD SBO).
