What are two examples of canning?

Two examples of canning include water bath canning and pressure canning. Water bath canning is typically used for high-acid foods like fruits, jams, and pickles, where jars are submerged in boiling water to seal them. Pressure canning is necessary for low-acid foods such as vegetables, meats, and poultry, as it uses high pressure to reach temperatures that eliminate harmful bacteria. Both methods preserve food for long-term storage while maintaining flavor and nutritional value.
