Groundnut oil has the flavour of peanut and can be heated to high temperatures without smoking, which makes it suitable for deep-frying and stir frying particularly french fries and chicken. It is often used in salad dressings, marinades, and baked goods. The oil also has a longer shelf life because it contained smaller amount polyunsaturated fatty acids that are prone to oxidation. The groundnut oil made from these plants contains about 45% monounsaturated fatty acids, 38% polyunsaturated fatty acids, and 17% saturated fatty acids.
