Edible Cottonseed Oil Refining Process Introduction
...
Cotton Seeds has a similar structure with other oilseeds( such as sunflower), the core shell coated with kernel (seed). Cottonseed oil used in salad oil, salad dressing, mayonnaise, or chips and other snacks, because its flavor stability, not disguise original taste.
Cottonseed oil is obtained as a byproduct of cotton production. Even though the production of cottonseed has fallen significantly since the invention of synthetic fibers, cottonseed oil still has a proportion of the edible oils market. The oil is very rich in unsaturated fatty acids, linoleic acid constituting about two-thirds of these.

In the first stage of chemical refining, a separator separates the soapstock with the fatty acids neutralized by acid and caustic. The second stage of refining the oil then follows; this is a second treatment of the oil with caustic to remove as much as possible of the gossypol. Gossypol is a pigment which gives raw cottonseed oil an almost black color. In the third stage, another separator performs the task of removing the wash water from the oil which has been washed with hot water. The pure cottonseed oil can now be dried, bleached and deodorized.
