Salt substitute

Salt substitutes are ingredients used to replace the salty taste of sodium chloride (table salt). They are often potassium-based, such as potassium chloride, but can also be other mineral salts. They are manufactured to mimic the flavour profile of salt, often with added flavour enhancers to improve taste.

Manufacturers use salt substitutes to reduce the sodium content of foods, appealing to consumers looking to lower their salt intake. They are commonly found in processed foods like breaded fish, fishcakes, and savoury snacks, where they provide a salty flavour without the high levels of sodium chloride.

Potassium chloride, a common salt substitute, is authorised as a food additive in the UK and listed on the Register of Food Additive Authorisations. EFSA has evaluated potassium chloride and established an Acceptable Daily Intake (ADI). While reducing sodium intake is generally recommended by the NHS to help manage blood pressure, individuals with certain medical conditions, particularly kidney problems, should consult their doctor before consuming high amounts of potassium-rich foods or salt substitutes, as excessive potassium can be harmful.
