Canning involves processing food in jars or cans and sealing them in airtight containers to prevent the growth of microorganisms and increase the shelf life of the food. The food is first prepared and packed into jars or cans, then heated to a specific temperature to kill any bacteria or microorganisms present. The containers are then sealed to prevent any air or bacteria from entering. Canning is a popular method of preserving fruits, vegetables, meats, and fish.
