What it is
Potassium chloride is a mineral salt that occurs naturally as the mineral sylvite. It is manufactured for use as a salt substitute and in industrial applications. It is a white crystalline solid that is odorless and has a taste similar to sodium chloride (table salt).
Why it's used
Manufacturers use potassium chloride as a salt substitute to reduce sodium content in foods. It can also be used as a firming agent, a flavor enhancer, and a nutrient supplement. It is commonly found in reduced-sodium processed foods like chips, pretzels, pasta dinners, and chewing gum.
Health notes
Potassium chloride is generally recognized as safe (GRAS) by the FDA for use in food. It is an essential nutrient that plays a role in maintaining fluid balance and nerve function. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated potassium chloride. While it is a salt substitute, high intake can cause gastrointestinal upset in some individuals. People with certain medical conditions, such as kidney disease, should consult a doctor before consuming foods with high levels of potassium chloride.
Allergen info
Potassium chloride is not derived from any of the nine FDA major allergens and does not contain gluten.
