Sodium Citrate (Food Grade) is a white, crystalline powder with a slightly salty and tart taste, commonly used as a food additive (E331). It is the sodium salt of citric acid and is highly soluble in water. Known for its buffering properties, sodium citrate helps regulate acidity and maintain pH levels in various food products. It is widely used in the food and beverage industry due to its ability to enhance flavor, improve texture, and increase the stability of formulations. Additionally, it acts as a preservative, extending the shelf life of perishable items by preventing spoilage and maintaining product freshness.

In the dairy industry, sodium citrate is essential in processed cheese production, where it acts as an emulsifying agent, ensuring a smooth and consistent texture by preventing protein coagulation. It is also used in carbonated beverages to balance acidity and improve taste. In meat and poultry processing, sodium citrate helps retain moisture and improve the tenderness of the final product. Furthermore, it plays a key role in confectionery and baked goods by controlling crystallization and enhancing product consistency.

Beyond the food industry, sodium citrate has pharmaceutical and medical applications. It is commonly used in antacid formulations to relieve heartburn and indigestion. Due to its anticoagulant properties, sodium citrate is also used in blood storage solutions to prevent clotting. Its versatility makes it an essential ingredient across multiple industries, ensuring quality, stability, and functionality in various products.
