Walnut oil is widely used in the culinary world for its rich, nutty flavor. It is often drizzled over salads, pasta, or roasted vegetables to enhance taste. Due to its low smoke point, it is not ideal for high-heat cooking but works well as a finishing oil. In the cosmetic industry, walnut oil is valued for its moisturizing properties. It is commonly found in skincare products like lotions, creams, and soaps, helping to nourish and soften the skin. Its high content of omega-3 fatty acids and antioxidants also makes it beneficial for hair care, promoting shine and reducing scalp dryness. Additionally, walnut oil is used in art as a base for oil paints and as a wood finish, providing a durable and attractive coating for furniture and other wooden items. Its natural properties make it a versatile ingredient across various applications.
