Sodium Technological functions of salt in the manufacturing of food and drink products

Salt (sodium chloride) is used in a variety of processed foods. It not only confers its own specific flavour on products, it is also used to enhance and modify the flavour of other ingredients. The reasons for using salt can be divided into three broad categories: processing reasons, sensory (taste) reasons, and preservative reasons. In some cases it performs all three of these functions, and in many situations the distinction between them is not clear‐cut.
