Canned meats are preserved meat products that are sealed in airtight containers, typically made of metal or glass. This preservation method helps extend the shelf life of the meat, making it convenient for storage and use. Common types of canned meats include spam, tuna, and chicken, which can be easily added to various dishes or eaten on their own. The process of canning involves cooking the meat, placing it in a can, and then sealing it to prevent bacteria from entering. This method not only keeps the meat safe to eat for long periods but also retains its flavor and nutritional value. Canned meats are often used in emergency food supplies and camping meals due to their durability and ease of preparation.
