• 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.
  • 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.
  • How is soybean oil prepared?
  • Preparing soybean oil involves cracking and dehulling, where soybeans are cracked open to break into smaller pieces. Once cracked, the outer hulls are carefully removed with the help of a machine called a Dehuller. It results in the revealing of the cotyledons, which are the embryonic seed leaves of the soybean.
  • 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.
  • Which country produces the most soybean oil?
  • The country is followed by the U.S., Brazil, and Argentina in the second, third, and fourth spots in soybean oil production ranking. During 2021 and 2022, China held its position as the top producer of soybean oil, boasting an impressive production volume of approximately 15.68 million metric tons.
  • Why was soybean oil a problem in the 1940s?
  • In the early 1940s, soybean oil was considered the biggest problem of the soybean industry. It was neither regarded as an excellent edible oil nor as a good oil for industrial paint. The crop was first known to be cultivated in China, which slowly immigrated to the rest of the world.
