Knowra Salt Salt Salt is sodium chloride, an ionic compound composed of sodium and chloride ions. It is used to season and preserve food and occurs naturally in seawater and mineral deposits.
Sodium chloride : An ionic compound made of sodium and chloride ions, with the formula NaCl. This is the chemical identity of the salt used in food.
Curing (food preservation) : Preserving food by applying salt, nitrite, smoke, or combinations of these treatments. Salt is a traditional curing agent for meat and fish.
Ionic bond : An electrostatic attraction between oppositely charged ions, commonly formed after electron transfer. Attraction between sodium and chloride ions holds salt’s crystal lattice together.
Sodium in biology : The roles of sodium ions in biological processes, including fluid balance and nerve signaling. Salt is a major dietary source of sodium, an essential but tightly regulated ion.
Salting : A food-preservation method that applies salt to draw out moisture and inhibit spoilage. Salt preserves food by reducing available water and hindering many microbes.
Pickling : Preserving food in an acidic brine or other acidic solution. Salt is commonly dissolved in pickling brines to season food and shape fermentation.
Crystal structure : The orderly, repeating arrangement of atoms, ions, or molecules in a crystalline solid. Solid salt forms a repeating cubic arrangement of sodium and chloride ions.
Hypertension : Persistently elevated blood pressure that increases the risk of cardiovascular and other diseases. High sodium intake can raise blood pressure, especially in salt-sensitive people.
Osmosis : The net movement of water across a selectively permeable membrane toward a region of higher solute concentration. Salt draws water from food and microbial cells through osmotic effects.
Brine : A solution of salt in water, often used in food processing and preservation. Brine carries dissolved salt into foods during curing and pickling.
