  • What is soybean oil used for?
  • Most of the remaining residue (soybean meal) is used as animal feed. In the 2002¨C2003 growing season, 30.6 million tons (MT) of soybean oil were produced worldwide, constituting about half of worldwide edible vegetable oil production, and thirty percent of all fats and oils produced, including animal fats and oils derived from tropical plants.
  • What is soybean oil refining?
  • Soybean oil refining is to add edible phosphoric acid, sodium hydroxide, decolourisation active white clay and other process auxiliaries, after a series of processes to remove impurities and components affecting the colour, stability and flavour, to improve the quality, flavour and storage stability.
  • How to produce soybean oil?
  • To produce soybean oil, firstly, soybean seeds are cracked for further process. Most manufacturers collect crude oil, which was extracted from soybean seeds. Then they start it to convert to fresh soybean oil. We are discussing the popular and reliable one which is called Caustic Refining Process:
  • How to neutralize alkali refining of soybean oil?
  • Neutralization of Alkali Refining: It is the second and of the most important steps of refining soybean oil. In this step, all types of free fatty acids are removed. Crude soybean oil is neutralized by using sodium hydroxide. In this step, some sodium soaps are generated automatically, which can be used for industrial purposes.
