Which term is used for a process that preserves food by applying heat and is commonly used for canning?

Explanation:
Thermal processing is the heat-based preservation method most associated with canning. It involves applying high heat (often under pressure in a retort) to sealed containers to destroy pathogenic and spoilage microorganisms and inactivate enzymes, creating a shelf-stable product. This approach differs from blanching, which is a short, pre-canning heat treatment to inactivate surface enzymes and reduce surface microbes but doesn’t by itself guarantee long shelf life. Dehydration preserves by removing water, not by heat treatment to preserve canned products. MAP, or modified atmosphere packaging, changes the gas inside the packaging to slow spoilage and does not involve heating the food. Thus, the term that best describes the heat-preserving process used in canning is thermal processing.
