Peanut oil is a type of vegetable oil that is derived from peanuts (Arachis hypogaea), also known as groundnuts. It is a popular cooking oil in many parts of the world and is used for both culinary and cosmetic purposes. Peanut oil is usually a pale yellow color with a mild nutty flavor and aroma, making it a popular choice for use in salad dressings, marinades, and sauces. It also has a high smoke point, making it an excellent choice for deep frying and stir-frying. Peanut oil is a great source of unsaturated fats, including both monounsaturated and polyunsaturated fatty acids, which are beneficial for heart health. Additionally, it is rich in vitamin E, which has antioxidant properties.
