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.
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 soybean oil extracted?
The expanding process involves heating the cleaned soybeans to facilitate soybean oil extraction. This can be achieved through mechanical pressing or by using solvents like hexane. Mechanical pressing involves physically pressing the soybeans to release the oil, while solvent extraction is a more efficient method for large-scale production.
What is the processing line for soybeans?
The processing line copes with the following processes: soybeans dehulling or decortication, soy grinding, mixing and heating up due to high pressure, high shear and temperature, decreasing of trypsin inhibitor and urease activity, pressing out the oil from the full fat soybean.
