Bean oil , also known as groundnut oil or arachis oil , is a light-flavored vegetable oil derived from peanuts. This oil is available with a strong nut flavor and aroma, analogous to sesame oil.
It is often used in American, Chinese, South Asian and South East Asian cuisines, both for general cooking, and in the case of fuel oil, to taste.

Usage
Pure peanut oil has a smoke point of 320 Â ° F/160 Â ° C. and is used as a flavoring for dishes similar to sesame oil. Fine peanut oil has a smoke point of 450 Â ° F/232 Â ° C generally used for frying food batch volumes such as French fries.

Composition
The major components of 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, lignoseric acid and other fatty acids.
Antioxidants such as vitamin E are sometimes added to increase the shelf life of oil.
Nutritional content
According to USDA data on the basis of the following table, 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.
Health issues
Poison
Very fine peanut oil can contain traces of hexane, a petroleum by-product used to maximize the separation of oil from a peanut solid. The EPA identifies hexane as neurotoxin in rat studies. There are no specific rules regarding the limits of hexane use in cooking oil. If quality control is ignored, peanuts containing mushrooms that produce highly toxic aflatoxins may end up polluting the oil derived therefrom.
Medical considerations
Vitamin E is added as a preservative for fine peanut oil, which can be a problem for people on blood-thinning medications, if consumed in excess.
Allergen
Those with peanut allergy can consume very fine peanut oil, but must avoid organic oil first.
Most of the very fine peanut oil removes peanut allergens and has proven safe for "most people who are peanut allergies". However, cold peanut oil can not eliminate allergens and thus can be very dangerous for people with peanut allergies.
Because the level of processing for a particular product is often unclear, "avoidance is wise."
History
The lack of whale oil in the Confederation made peanut oil an attractive alternative during the American Civil War. Oil has increased its use in the United States during World War II, due to other oil shortages.
Other uses
Peanut oil, like other vegetable oils, can be used to make soap with a saponification process. Oil is safe to use as a massage oil. George Washington Carver nut researcher sells peanut massage oil.
Biodiesel
At the 1900 Paris Exhibition, Otto Company, at the request of the French Government, showed that peanut oil could be used as a fuel source for diesel engines; this is one of the earliest demonstrations of biodiesel technology.
Suspension agent
Some drugs and vitamins use arachis oil as a suspension agent.
