How is vegetable oil processed?
Vegetable oils are created from the extraction of oils from plant materials. This process involves the crushing and removing of the unwanted components, which is typically achieved through mechanical pressing. Vegetable oil extraction can also be completed by chemical extraction using a solvent.
