chemical preservation
Molecular decay prevention
Chemical preservation is the use of substances to prevent decay or spoilage in food, biological specimens, or other perishable materials.
Salt, sugar, vinegar, and synthetic additives like sodium benzoate work by inhibiting bacterial growth or oxidation.
The practice extends from ancient food curing to modern embalming: The body was prepared for viewing through chemical preservation.
