home preservation

Home preservation refers to methods of extending food shelf life using domestic rather than industrial techniques—canning, pickling, fermenting, drying, smoking, or freezing produce and other perishables at home.

The practice connects to self-sufficiency, food security, and seasonal eating: She learned home preservation from her grandmother, who canned everything from tomatoes to peaches.

The term occasionally describes maintaining or restoring residential buildings, though food preservation is the dominant sense.
