Trisodium phosphate is an inorganic compound with the chemical formula of Na3PO4. It is widely used in food processing. It is mainly used as water retention agent, stabilizer, acidity regulator and so on. It can improve the structure and taste of food and improve the nutrition of food.


1. The product quality improver can improve the complex metal ions, pH value and ionic strength of food, so as to improve the binding force and water holding capacity of food. According to Chinese regulations, it can be used in cheese with a maximum dosage of 5g / kg; in western ham, meat, fish, shrimp and crab, the maximum dosage is 3.0g/kg; in canned food, juice, beverage and dairy products, the maximum dosage is 0.5g/kg.

2. In chemical industry, textile, printing and dyeing, papermaking, power generation and other industries, it is used as softener and detergent, boiler scale inhibitor, water softener in paper dyeing, acid and alkali buffer of adhesive for production of glossy paper, fixing agent in printing and dyeing, mercerizing enhancer of fabric, and anti embrittlement agent of production line. In metallurgical industry, it is used for chemical degreasing and decontamination, and as an excellent accelerator in photographic development solution. Tooth cleaner and bottle cleaner. Coagulant of rubber milk. Sugar juice purifier. Phosphate plays an important role in improving the quality of food processing. For example, in meat products, it can maintain the water holding capacity of meat and enhance the binding force, so as to reduce the loss of nutrients in meat and preserve the tenderness of meat. It is also used as emulsifier, nutritional supplement and quality improver in food processing. It is a raw material for preparing alkaline water for pasta, and also used for refining granulated sugar and manufacturing α - starch. It is also used as detergent for food bottles and cans.

3. Solid trisodium phosphate (TSP) is a kind of strong alkali weak acid salt with strong alkalinity and high solubility. It has stable chemical properties and can be stored for a long time. TSP is added to the spray water of containment spray system (EAS) to replace NaOH, It can adjust the pH value of the spray liquid, effectively remove the iodine gas released from the leaking cooling water to the containment, avoid the injury of strong alkali to the staff, and is easy to clean after the accident.
