Technical Abstract: Groundnut oil is expressed from the seed of Arachis hypogaea L., commonly known as groundnut or peanut. More than 50% of the groundnuts produced throughout the world are crushed for oil. The seed of the groundnut fruit commonly contain 40-50% total oil. Peanut oil uses include cooking and frying oil, preparation of shortenings, margarines, and mayonnaise. As a cooking oil, especially in deep-fat frying, groundnut oil is excellent since it has a smoke point of 229.4 C. Groundnut oil is composed of mixed glycerides and contains a high proportion of unsaturated fatty acids, in particular, oleic (18:1) and linoleic (18:2). Tocopherol, sterol, phospholipd antioxidant compounds and general properties of peanut oil are discussed.
