  • What are the two main refining processes in the oil industry?
  • The two main refining processes in the oil industry are chemical refining and physical refining. These processes include stages such as degumming, neutralization, bleaching, deodorization, and winterization.
  • What is chemical refining of oil?
  • Chemical Refining of Oil Chemical refining is the traditional method used since ancient times. It can be used for all fats and oils even when they have been slightly degraded. Each step of the refining process has specific functions for removing some undesirable compounds.
  • What are the benefits of refining edible oil?
  • refining are that it reduc es oil losses and minimizes liq uid effluent generation. . V alue-addition t o edible oil refining by -products Refining pr oduces by -products like gums and deodorized distillat e (DOD). Different forms of phospholipids can be obtained from gums.
  • What are the major concerns in oil refining?
  • The major concerns in the oil refining process are unsaturated fatty acids, tocopherols, phytosterols, and other antioxidant components to preserve the nutritional quality of the oil. Changes of the bioactive compounds need to be monitored during the refining process of edible oil to minimize the loss of bioactive compounds.
  • What is Physical refining?
  • Physical refining is primarily used for high-FFA oils like palm and sunflower oil. In this process, free fatty acids are removed during the deodorization step by steam stripping as a distillate. The process steps include optional acid/enzymatic degumming, bleaching, stripping-deodorizing, and optional winterizing.
  • What is vegetable oil refining?
  • As vegetable oil is an important component of the human diet, the source and the processing play an important role in consumer acceptability. To remove impurities that affect the color, palatability, stability, and safety of oil, crude vegetable oil must be refined. This review highlights the processes and steps used in vegetable oil refining.
