Extracted from whole , soybean oil is used in both edible and inedible products. It is flexible, high-quality oil that is used in food product manufacturing as well as in the production of inedible products such as caulks, mastics, plastics, and resins.Once it is cracked, the soybean goes through several processes in order to produce soybean oil. These include soybean hull removal, flaking and conditioning, hexane extraction, degumming, refining, and several other processes.
