• What is alkaline refining?
  • This alkaline refining process is applicable for majority of the crude oils, including oils with low quality, except for castor oil (Zeldenrust 2020).
  • What is a Physical refining process?
  • In general, physical refining includes the following three main processing steps: Sometimes the dewaxing process is added for types of oils rich in waxes (e.g., fatty acids with low solubility in oils and high-melting esters of fatty alcohols), such as corn, rice bran, canola, and sunflower oils .
  • How does Alfa Laval refine crude oil into edible oil?
  • Refining crude oil into edible oil requires deep process knowledge¡ªfrom degumming, neutralization and dewaxing through to bleaching, deodorizing and GE and 3-MCPD mitigation. Edible oil producers worldwide rely on Alfa Laval know-how to remove impurities and volatile components and optimize refining processes.
  • What is refining in edible oil processing?
  • Refining is the last step in edible oil processing. We are committed to making every drop of oil safe, healthy and nutritious. Value-adding by-products may be produced from processing stages like Degumming, Neutralization, Bleaching, Dewaxing/Winterization and Deodorization.
  • 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.
  • Why is degumming important in vegetable oil refining?
  • Degumming is a crucial step in the refining process of vegetable oils . It allows the elimination of ¡°gums¡± or ¡°mucilage,¡± composed mainly of phospholipids from the crude oil as well as compounds such as carbohydrates, proteins, and trace of metals [9, 34]. Phospholipids or phosphatides are naturally present in oils.
