• Why does crude oil need to be refined?
  • Crude oil extracted from vegetable and fish sources contain mono-, di-, triacylglycerols along with impurities, which necessitates refining. The main objective of refining is to remove the contaminants that adversely affect the quality of oil, thereby reducing the shelf life and consumer acceptance.
  • 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.
  • Why is refining edible oil important?
  • Refining of edible oil by chemical or physical processes aims towards removing the undesirable impurities that affect oil quality and stability. Understanding the chemical nature of oil and associated impurities is important to designing refining steps.
  • How can edible oil refining reduce production costs?
  • Paper presented at the Edible Oil Refining Update short course at the 103rd AOCS Annual Meeting and Expo, Long Beach, Summary In edible oil refining, the continuous effort to reduce overall production costs is mainly achieved by increasing plant capacities, installation of mono feedstock plants, and increasing the…
  • What is the difference between chemical and Physical refining of crude oil?
  • For crude edible oil, chemical (alkali) and physical refining are the standard processes used in industry. In chemical refining, FFA are removed by neutralization with alkali, while in physical refining it is removed by distillation during deodorization. Compared to chemical refining, oil losses are reduced in physical refining.
  • What is crude oil refining?
  • Treatment that eliminates undesirable and toxic components in crude oils is known as ¡°refining¡± . Refining is practically mandatory for crude oils that cannot be consumed as virgin oils to provide a product with an attractive appearance, a neutral taste, and more resistance to oxidation.
