The production of vegetable oil involves the removal of oil from the plant components. The extracted oil can then be purified and, if required, refined, or chemically altered to remove unwanted components that make oils unappealing to consumers, while trying to cause the least possible damage to the neutral oil as well as minimum refining loss.
