preservation methods
Ways to maintain
Preservation methods are techniques used to prevent food, materials, or other perishable items from spoiling or deteriorating.
For food, these include refrigeration, freezing, canning, drying, salting, smoking, and pickling—each working by slowing bacterial growth or removing moisture.
Beyond food, preservation methods extend to protecting documents, artifacts, and biological specimens.
Traditional preservation methods like smoking meat have been used for thousands of years.
