What it is
Potassium and sodium citrates are salts of citric acid, a weak acid found naturally in citrus fruits. They are produced commercially through the neutralization of citric acid with potassium or sodium hydroxide, respectively. These compounds are often used in combination to achieve specific pH and buffering properties.
Why it's used
These salts are used as acidity regulators and emulsifiers in a wide variety of foods. They help control pH, prevent spoilage, and improve texture, particularly in processed cheeses, dairy products, and baked goods. They can also act as sequestrants, binding metal ions that can cause spoilage.
Health notes
Potassium and sodium citrates are generally recognized as safe (GRAS) by the FDA for use in food. They are metabolized similarly to other salts and citric acid. International bodies like JECFA have evaluated these substances. At typical dietary intake levels, they are not associated with adverse health effects.
