Purpose and Function
E331 can refer to any of the sodium salts of citric acid: monosodium citrate, disodium citrate, or trisodium citrate.
Acidity Regulator: It is used to control and adjust the pH levels in food products, ensuring stability and the desired taste.
Emulsifier: It helps blend ingredients that typically separate, such as oil and water, to create a uniform mixture.
Sequestrant: Trisodium citrate binds metal ions, preventing them from catalyzing oxidation and spoilage, thereby enhancing the shelf life and stability of products.
Buffering Agent: It maintains pH stability during processing and storage, protecting the integrity of the food product.
Other Uses: Beyond its role in food, it is utilized in pharmaceuticals to control acidity, in cosmetics for pH adjustment, and in laboratory settings as a buffer solution.
