Filtered groundnut/ peanut oil have been used in India since generations. Refining of oil was introduced in the 1950s. The first refined groundnut oil was called Sipahi but it gained popularity under the brand name Postman. Peanut oil is an organic oil derived from peanuts, noted to have the slight aroma and taste of its parent legume. Peanut oil is appreciated for its high smoke point relative to many other cooking oils. Its major component fatty acids are palmitic acid, oleic acid, and linoleic acid. The oil also contains some 6-8% (total) of arachidic acid, arachidonic acid, behenic acid, lignoceric acid and other fatty acids. Peanut oil is most commonly used when frying foods, particularly French fries and other preparations. They are presumably less filtered, retaining some peanut proteins for the sake of flavour and nutrition.
