Introduction

Sodium citrate is a sodium salt of citric acid, commonly used as a food additive. It appears as a white, crystalline powder and is known for its slightly salty, citrus flavor. With the chemical formula C6H5Na3O7, sodium citrate serves multiple purposes in food and beverage applications, including acting as a preservative, flavor enhancer, acidulant, and emulsifier.

Applications of Sodium Citrate

1. Food Preservation:

  - pH Regulation: Sodium citrate acts as a buffering agent, helping to control and stabilize the pH of food products. This can enhance preservation and maintain the quality of various items, such as sauces and dressings.

  - Inhibition of Microbial Growth: By controlling acidity, sodium citrate helps inhibit the growth of certain bacteria, thus serving as a preservative for perishable foods.

2. Flavor Enhancement:

  - Balancing Flavor: Sodium citrate is used to improve the taste of various food and beverage products. It can enhance overall flavors and is often used in beverages to provide a refreshing taste.

  - Sourness Reduction: It can help balance and reduce excessive sourness in food, making it a popular ingredient in fruit-flavored products.

3. Emulsification:

  - Stabilizing Agent: Sodium citrate is used as an emulsifier in processed foods, particularly in cheese production. It helps maintain the uniformity and texture of cheese products by preventing oil separation.

  - Creamy Texture: In dairy products, it contributes to achieving a smooth, creamy texture in processed cheese and sauces.

4. Beverages:

  - Carbonated Drinks: Sodium citrate is commonly used in the beverage industry, particularly in soft drinks, to modulate acidity and improve taste.

  - Sports and Energy Drinks: It is frequently included in sports and energy drinks for its electrolyte properties, which can help with hydration.

5. Health and Nutritional Applications:

  - Sodium Absorption: Sodium citrate is used in some medical formulations and dietary supplements to assist with sodium absorption and help maintain electrolyte balance.

  - pH Regulation in Pharmaceuticals: It also serves as a buffering agent in certain pharmaceutical products, helping to stabilize the active ingredients.
