Refined Peanut Oil, also called by the name of arachis oil, is an edible vegetable oil extracted from peanuts. A widely used cooking oil in South Asian and Southeast countries, it is also popular in the western world. This all-purpose oil is known for its distinctive aroma, mild flavour and taste of its parent legume. Its high heat tolerance and high smoke point 450 degrees F (232.22 C), make it suitable for deep-frying and sauteing. Peanut oil is also a healthy oil for everyday use because it is high in monounsaturated and polyunsaturated fat.
Widely considered to be the finest all-round pure vegetable oil, Groundnut Oil is extensively used as an alternative to olive oil in the production of mayonnaise.
It is ideal for all cooking, baking, frying, roasting, sauces, dressings, salads and marinades.
Extremely full-bodied, Groundnut Oil can be used at higher temperatures than other oils and has a characteristic, slightly nutty taste whilst being odourless.

Groundnut (peanut) oil is high in mono-unsaturated fats and is more stable than any other type of oil. It usually does not require artificial additives. It is extremely robust and produces fewer flavour defects with long term use as compared with many other oils. Groundnut oil has a characteristic, slightly nutty taste whilst being odourless.
