- Trisodium citrate dihydrate is widely used in foods, beverages, pharmaceutical, cosmetic, and personal care products as:
Trisodium Citrate is found in carbonated beverages, dairy products, confectionery, prepared foods, canned meats and vegetables, margarine, mustard, sauces, mayonnaise, spices, jams, and much more.
– An acidity regulator: maintain the proper pH of the product. It is found in sodas, especially those with lemon flavor, energy drinks, desserts or jams.
– A sequestering agent: binds metal ions, called chelates. Thanks to this, the consumer is protected from the harmful effects of heavy metals in foods.
– An emulsifier: prevents the separation of fats. Application in cheese, make cheese not become greasy after melting.
– A preservative: protects the fats in the product from oxidation and rancidity, and prevents color changes in foods.
