Soybean Oil 

a fatty vegetable oil obtained from the seeds of the soybean plant (Glycine). The average contents of the various fatty acids in soybean oil are 51–57 percent linoleic acid, 23–29 percent oleic acid, 4.5–7.3 percent stearic acid, 3–6 percent lino-lenic acid, 2.5–6.0 percent palmitic acid, 0.9–2.5 percent ara-chidic acid, up to 0.1 percent palmitoleic acid, and 0.1–0.4 percent myristic acid. Soybean oil has a solidifying point between –15° and –18°C, an iodine value of 120–141, and a kinematic viscosity at 20°C of 59–72 x 10^–6 m²/sec. It occupies a leading place in the world production of vegetable oils. Refined soybean oil is used in food and as a raw material for the production of margarine. A valuable component of soybean oil is lecithin.
