Sodium Citrate
INS 331 / E331
Also listed as: Trisodium citrate, Sodium citrates
What it is
Trisodium citrate is the sodium salt of citric acid, an organic acid naturally found in citrus fruits. It is generally produced commercially by neutralizing citric acid with a sodium-containing compound. It is a white, water-soluble substance commonly used to control acidity and improve the stability and texture of products. Sodium citrates is a broader term that can refer to different sodium salts of citric acid, including trisodium citrate.
Why it’s used
What is it used for in food?
Trisodium citrate and other sodium citrates are used as food additives to regulate acidity, stabilize products, and improve texture. They are commonly found in processed cheese, dairy products, and beverages. In processed cheese, they help achieve a smooth, creamy consistency by preventing fat and water from separating during melting. In beverages and other processed foods, they help control acidity and maintain consistent flavour, texture, and product quality.
What is it used for in cosmetics?
Sodium citrate is also used in cosmetics and personal-care products, including skincare and haircare formulations. It primarily functions as a pH regulator and buffering agent, helping maintain the desired acidity of a product. It can also act as a chelating agent by binding certain metal ions that might otherwise affect product stability. These functions help maintain the quality and consistency of cosmetic formulations during storage.
Typically found in:
- Drinks
- Processed cheese
- Snack seasonings
