WHAT IS BRINE?
Brine is a solution of salt (usually sodium chloride) in water. In different contexts, brine may refer to salt solutions ranging from about 3.5% (a typical concentration of seawater, or the lower end of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature).
Brine is used to preserve vegetables, fruit, fish and meat in a process known as brining. Brine is also commonly used to age halloumi and feta cheeses, or for pickling foodstuffs, as a means of preserving them (or increasing taste). Brine is a common fluid used in large refrigeration installations for the transport of thermal energy from place to place. It is used because the addition of salt to water lowers the freezing temperature of the solution and the heat transport efficiency can be greatly enhanced for the comparatively low cost of the material.
