Canning (canning industry)

Canning is a method of preserving food by sealing it in airtight containers, typically metal cans, and heating them to kill harmful bacteria. This process extends the shelf life of foods, allowing for safe consumption long after their harvest or production. The canning industry involves the large-scale production of canned goods, which includes fruits, vegetables, meats, and soups. It plays a crucial role in food safety, convenience, and reducing food waste. The canning process not only maintains nutritional value but also enables foods to be stored for months or even years without spoiling.
