What Is Walnut Oil?
Walnut oil is extracted from the nuts of the walnut tree, primarily from the species Juglans regia, commonly known as the English walnut or Persian walnut. The oil is obtained through cold-pressing the nuts, which helps retain its rich flavor and nutritional properties.
The oil has a distinct, nutty aroma and a golden to dark amber color. It is known for its high content of polyunsaturated fatty acids, particularly omega-3 and omega-6 fatty acids, which are essential for maintaining overall health. Walnut oil is also rich in antioxidants, vitamins, and minerals, contributing to its versatility in various applications.
