Potassium Tripolyphosphate (KTPP), CAS 113845-36-8 | Water Retention Agent & Phosphate Additive

Product Overview 

Potassium Tripolyphosphate (KTPP), Cas No.: 13845-36-8, E No.: E451,  is a high-purity phosphate additive with excellent sequestering, emulsifying, water-binding and pH stabilizing functions. It features good water solubility, strong chelating capacity and wide compatibility with food ingredients.

It is a multi-functional food additive widely applied in meat and seafood products, dairy products, processed cheese, beverages and various food formulations to improve water retention, stabilize texture, bind metal ions and optimize production performance. It can also be used as auxiliary raw material for industrial water treatment and detergent formulations.

Character

Potassium Tripolyphosphate has stable chemical properties and excellent solubility in water. It is an alkaline polyphosphate with strong metal ion chelating ability, effectively binding calcium, magnesium and other metal ions in food systems. Food grade KTPP is produced through strict purification process with low impurity content, complying with global food additive standards. It shows outstanding water-binding and protein-modifying effects, particularly in meat and seafood processing, helping to improve yield and maintain juicy texture. Industrial grade KTPP provides consistent batch quality for detergent and water treatment applications.

Main Functions

1.Sequestrant & Chelating Agent — bind calcium, magnesium and other metal ions, inhibit oxidation and discoloration

2.Water Retention Agent — improve water-holding capacity of meat and seafood, reduce cooking loss and maintain juiciness

3.Emulsifying Salt — promote protein emulsification and dispersion, stabilize texture in processed meat and cheese

4.pH Buffer & Stabilizer — maintain alkaline pH range, stabilize food systems during processing and storage

5.Texture Improver — enhance product tenderness, firmness and overall mouthfeel

6.Industrial Auxiliary Agent — auxiliary raw material for water treatment and detergent formulation

Applications

1.Meat & Seafood Processing (Core Application) KTPP is widely used in processed meat, seafood and aquatic products as a water-retention and texture-improving agent. It enhances yield, reduces purge loss during storage, and helps maintain tender, juicy and firm texture after cooking.

2.Dairy & Processed Cheese Applied in processed cheese, cheese spreads and dairy products as an emulsifying salt, promoting smooth melting and uniform texture.

3.Beverage & Functional Food Used as a sequestrant and stabilizer in beverages, protein drinks and functional food systems to prevent turbidity and oxidative deterioration.

4.Industrial Fields Industrial grade KTPP is used in detergent formulations, industrial water treatment and metal surface treatment as a chelating and dispersing auxiliary.
