The walnut industry encompasses the cultivation, processing, and distribution of walnuts, which are grown primarily for their rich nutrient profile and versatility across food applications. Walnuts are high in omega-3 fatty acids, antioxidants, and essential vitamins, which makes them increasingly popular among health-conscious consumers. Originating mainly from countries such as the United States, China, and Iran, walnuts are grown in temperate climates, with California leading global production due to its optimal growing conditions and advanced agricultural practices. In the food industry, walnuts are used in a variety of products, including bakery items, snacks, salads, and confectionery. Demand for walnuts has grown not only for their health benefits but also due to their popularity in plant-based diets, where they serve as a protein and fat source in vegetarian and vegan products. Walnuts are also processed into products like walnut oil, walnut butter, and walnut-based beverages, expanding their market reach and applications.
