Description
Historical preservation methods such as salting, pickling, and potting rely on chemical interventions to lower water activity and inhibit microbial growth.
Technical
Salting creates an osmotic gradient that draws water out of cells, reducing microbial metabolism. Pickling lowers pH through acetic or lactic acid, denaturing enzymes and creating an anaerobic environment. Potting seals the food and applies heat to form a vacuum seal, further reducing water activity.
Science
Primary Reaction
Osmotic dehydration, acidification, and vacuum sealing reduce water activity and inhibit microbial growth.
