Product Overview

Trisodium citrate dihydrate, widely referred to in the industry as sodium citrate, is the dihydrate form of trisodium citrate. It is a safe, non-toxic citrate salt with excellent pH buffering, chelating and emulsifying properties.

It is a multi-purpose food additive, capable of stabilizing pH value, binding metal ions and improving food texture. Its buffering characteristic helps maintain stable acidity and prevents sudden pH shifts during food production and storage.

Key Product Characteristics

1.Excellent pH buffering performance, stable acidity in food systems

2.Good chelating capacity, binds metal ions to prevent oxidation and discoloration

3.Great emulsifying and texture-improving properties

4.Odorless, mild salty taste, will not affect the original flavor of food

5.High water solubility, easy to disperse evenly in liquid food systems

6.Conforms to international food additive standards for global export

Main Functions

1.Acidity Regulator & pH Buffer Stabilize pH value, resist sudden acid or alkali changes, maintain consistent taste in finished food.

2.Chelating Agent Capture metal ions, inhibit oxidation and browning, extend shelf life.

3.Emulsifier & Stabilizer Improve texture, prevent stratification and separation in dairy and beverage systems.

4.Flavor Stabilizer Protect original flavor of food and reduce taste deterioration during storage.

Application Scope

1. Dairy & Beverage: Used in milk drinks, cheese, yogurt and fruit beverages. Stabilizes emulsion, prevents precipitation and controls pH.

2. Meat Products: Applied in processed meat and ham to improve water retention, stabilize color and extend shelf life.

3.Confectionery & Jam: Used in jelly, jam and candy to adjust acidity and stabilize texture.

4. Other Food Processing: Also used in instant food, seasonings and canned food for pH adjustment and preservation.

Packaging & Storage
