Walnut oil, extracted from walnuts (Juglans regia), is a versatile oil rich in polyunsaturated, monounsaturated, and saturated fats. Its primary component is linoleic acid (60–62%), and it also contains beneficial antioxidants like γ-tocopherol, tannins, and flavonoids. Known for its delicate, nutty flavor, walnut oil is often used in cold dishes such as salad dressings but is less commonly used for high-heat cooking due to its cost and sensitivity to heat, which can affect its flavor. Cold-pressed walnut oil, produced with minimal processing, is more expensive but retains higher quality, while refined walnut oil is extracted with solvents to maximize oil yield. Walnut oil is also prized as a drying oil in the art world for its ability to form strong, flexible films, making it ideal for oil paints and varnishes. In woodworking, walnut oil is favored as a safe, edible finish for implements like wooden bowls, often mixed with beeswax to create a durable, non-rancid coating.
