Peanut oil, also known as groundnut oil or arachis oil, is a vegetable oil derived from peanuts. The oil usually has a mild or neutral flavor but, if made with roasted peanuts, has a stronger peanut flavor and aroma.
What is groundnut oil used for?
Made from peanut plant seeds, peanut oil — also known as groundnut oil — is commonly used in baking, sautéing, frying, and other forms of cooking.
Groundnut seeds contain about 45–56% oil and 22–30% protein  and many beneficial nutrients such as minerals, vitamin E, folic acid, niacin and antioxidants , biologically active polyphenolics, flavonoids and isoflavones
How groundnut oil is refined?
The refined oil is refined through bleaching and deodorization. This process essentially removes the components that might cause peanut-based allergies thereby making refined peanut oil, non-allergic. The high smoke point offered by refined peanut oil makes it an attractive frying oil for hotels and restaurants.
