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?
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.
How do you extract soybean oil from soybean flakes?
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. After expanding, the soybean flakes are drying to reduce their moisture content.
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.
