Groundnut oil, also known as peanut oil, is extracted from the seeds of Arachis hypogaea. It is prized for its mild, nutty flavour and high smoke point, making it a popular choice for frying and deep cooking. Rich in monounsaturated fats and vitamin E, groundnut oil supports heart health and provides natural antioxidant benefits. In addition to household cooking, it is widely used in the production of snacks, confectionery, and margarine.

The oil is also used in cosmetics, soaps, and traditional medicine as a lubricant. Groundnut cake, a by-product of oil extraction, is a valuable protein source for animal feed. India, China, Nigeria, and the United States are among the largest producers and consumers of groundnut oil. With growing demand for healthy edible oils, groundnut oil remains a staple in kitchens and industries worldwide.
