Curing (food preservation)

Curing preserves meat or fish by applying salt, nitrite, smoke, or combinations of these treatments. These methods reduce microbial growth and can alter flavor, color, and texture.

Water activity: A measure of how much water in a material is available to support chemical reactions and microbial growth. Salt lowers water activity, making cured foods less hospitable to many microbes.
Salting: Preserving food by applying salt to draw out moisture and inhibit microbial growth. It is the central technique in many meat and fish cures.
Bacon: Salt-cured pork belly, commonly smoked and sometimes treated with nitrite. It combines curing ingredients with smoking in a widely recognized meat product.
Refrigeration: Preserving food by keeping it at low temperatures that slow microbial growth and chemical change. Unlike curing, refrigeration slows spoilage without necessarily changing the food’s composition.
Osmosis: The net movement of water across a selectively permeable membrane toward a region of higher solute concentration. Salt draws water from microbial cells and food tissues during curing.
Brining: Treating food with a solution of salt in water, sometimes with sugar or other ingredients. Immersion in brine distributes salt through meat or fish.
Prosciutto: An Italian dry-cured ham, typically made by salting and aging a pig’s hind leg. Its long salt cure and drying show preservation without required smoking.
Freezing: Preserving food by lowering its temperature enough to freeze its water. Freezing relies on low temperature rather than salt or smoke as its main barrier.
Sodium nitrite: A chemical salt used in cured meats to inhibit microbes and contribute to characteristic color and flavor. It suppresses dangerous bacteria and helps produce cured meat’s pink color.
Drying: Removing moisture from food to slow spoilage and reduce microbial growth. Curing often combines salt with moisture removal for stronger preservation.
