Cottonseed Oil

 

a rich vegetable oil obtained from the seeds of the cotton plant (Gossypium) by pressing or extraction.

The specific component of cottonseed oil is the pigment gossypol, a toxic substance; the gossypol content determines the color and quality of the oil. Unrefined cottonseed oil is a reddish brown liquid, sometimes almost black in color, with a unique odor and bitter taste. Refined cottonseed oil has a straw yellow color.

The chemical composition and properties of cottonseed oil depend on the variety of cotton and the region and conditions of cultivation. Cottonseed oil contains 40–48 percent linoleic acid, 30–35 percent oleic acid, 20–22 percent palmitic acid, up to 2 percent stearic acid, up to 1.3 percent arachidic acid, and 0.3–0.4 percent myristic acid. It has an iodine value of 100–116 and a kinematic viscosity of 66.6 × 10–6 m2/sec at 20°C. Cottonseed oil is used to produce drying oil; refined cottonseed oil is a foodstuff and is used in the production of canned goods, margarine, and shortening.
