It is often used in Chinese, South Asian and Southeast Asian cuisine, both for general cooking, and in the case of roasted oil, for added flavor. Peanut oil has a high smoke point relative to many other cooking oils, so is commonly used for frying foods. Its major component fatty acids are oleic acid (46.8% as olein), linoleic acid (33.4% as linolein), and palmitic acid (10.0% as palmitin). The oil also contains some stearic acid, arachidic acid, behenic acid, lignoceric acid and other fatty acids.
Antioxidants such as vitamin E are sometimes added to improve the shelf life of the oil.

History
Shortage of whale oil in the Confederacy made peanut oil an attractive alternative during the Civil War. The oil had increased use in the United States during World War II, because of war shortages of other oils.
Nutritional content
According to the USDA data upon which the following table is based, 100 g of peanut oil contains 17.7 g of saturated fat, 48.3 g of monounsaturated fat, and 33.4 g of polyunsaturated fat.
Allergens and toxins
Most highly refined peanut oils remove the peanut allergens and have been shown to be safe for "the vast majority of peanut-allergic individuals". However, cold-pressed peanut oils may not remove the allergens and thus could be highly dangerous to people with peanut allergy. Since the degree of processing for any particular product is often unclear, "avoidance is prudent." If quality control is neglected, peanuts that contain the mold that produces highly toxic aflatoxin can end up contaminating the oil derived from them.
Other uses
Peanut oil, as with other vegetable oils, can be used to make soap by the process of saponification. The oil is safe for use as a massage oil. Peanut researcher George Washington Carver marketed a peanut massage oil.
Biodiesel
At the 1900 Paris Exhibition, the Otto Company, at the request of the French Government, demonstrated that peanut oil could be used as a source of fuel for the diesel engine; this was one of the earliest demonstrations of biodiesel technology.
Suspension agent
Some medicines and vitamins use arachis oil as a suspension agent.
