Canning is a method used for the preservation of a variety of foods, including vegetables, fruits, and meats. Pressure canning or water bath canning is used to preserve food based on the acidity level of the selected food. When proper canning practices are followed, the quality of fresh foods can be extended to safely consume many months beyond their usual expiration and decline in quality.
