Canned tuna is one of the most popular and widely used seafood products in the world, made from fresh tuna fillets (such as halibut or gaidar) that are cooked, steamed, or grilled, then packaged and sterilized in metal cans. This product is usually available in vegetable oil, brine, or water and is a nutritious and quick food source due to its high protein, omega-3 fatty acids, vitamins, and minerals. Canned tuna is a versatile food ingredient used in salads, sandwiches, pasta, pizza, and local dishes, and has a permanent place in many households' cupboards thanks to its long shelf life and ease of use.
