• What is refining a soybean oil?
  • Refining plays a key role in the manufacturing of edible oils like soybean oil. Its chief purpose is to eliminate impurities, volatile substances, and unwanted components from the crude oil. Refining thus results in the production of a high-quality, stable edible oil that is perfectly safe to consume.
  • How is soybean oil extracted?
  • Once the soybean seeds undergo the preparatory section processes, they are moved to the solvent extraction plant. The solvent extraction process is a common method used for soybean oil extraction. The aim is to use a solvent for dissolving a target solute, and wash it out of the solid plant component.
  • What is the preparatory section in the soybean oil manufacturing process?
  • First comes the preparatory section in the soybean oil manufacturing process. It marks the initial stage where raw soybeans are processed to make them ready for oil extraction. Upon arrival at an oil mill, seeds often contain various foreign materials acquired during harvesting or transportation.
  • What is deodorization in soybean oil refining?
  • Deodorization is the final stage of soybean oil refining. Here, the oil is heated under vacuum to remove any volatile compounds and lingering odor. Steam is used to take away these undesirable components, resulting in a odorless and clean product, which is suitable for consumption.
  • Where did soybean oil come from?
  • Production of soybeans expanded from the southern part of the United States. The industries that process soybeans to produce soy oil and soybean meal are called processing or crushing industries. Oil from the soybeans can be removed by any one of the two oil extraction methods.
  • How is crude oil produced in a soybean crushing plant?
  • The crude oil is usually water degummed in the crushing plant which generates an additional flow, consisting of gums (or lecithin). Table 1 presents the main quality parameters (optimal contents) of the major products from soybean crushing.
