food preservation
Keeping edibles safe
Food preservation is any method of treating food to prevent spoilage and extend its usable life.
Traditional techniques include salting, smoking, drying, pickling, and fermenting.
Modern methods add refrigeration, freezing, canning, and vacuum sealing.
The goal is always the same: slow bacterial growth and chemical breakdown to keep food safe and edible longer.
Home canning requires careful attention to food preservation guidelines.
