Canned products are food items that are preserved in metal containers, known as cans. This method of preservation helps to extend the shelf life of the food by sealing it from air and bacteria. Common canned products include vegetables, fruits, soups, and meats, making them convenient for storage and easy to prepare. The canning process involves cooking the food, placing it in a can, and sealing it tightly. This process not only preserves the food but also retains its nutrients. Canned products are widely available in grocery stores and are often used in cooking and meal preparation due to their long shelf life and ease of use.
