Product Overview 

Sodium Hexametaphosphate (SHMP) is a long-chain polyphosphate salt with high water solubility and strong metal ion binding capacity. It is widely used as a sequestering agent and water retention agent in food processing.

SHMP effectively chelates calcium, magnesium and other metal ions in food systems, preventing undesirable crystal formation, discoloration and sediment precipitation. In canned seafood, it suppresses struvite crystal development that causes gritty texture. In meat and seafood processing, it assists in water retention, reducing cooking loss and maintaining tender, juicy texture.

SHMP also functions as a dispersing agent, helping to maintain uniform particle distribution and system stability. It is applied in dairy products, processed cheese, beverages, fruit and vegetable processing, as well as selected industrial fields such as water treatment and detergent formulations.

Character

Sodium Hexametaphosphate appears as a white powder or glassy granular solid. It dissolves readily in water to form nearly neutral aqueous solutions, and remains stable under proper storage conditions.

Its long-chain polyphosphate structure provides exceptionally strong sequestering capacity compared with shorter-chain phosphates. SHMP has low heavy metal and impurity content, meeting international food additive safety specifications. It is compatible with a wide range of food raw materials and processing conditions.

Main Functions

1.Strong Sequestering & Water Retention Agent:  Powerfully chelate calcium, magnesium and other metal ions to prevent crystal precipitation, discoloration and oxidation in food systems. Deliver water retention performance for meat, poultry and seafood products to reduce cooking loss and maintain tender texture.

2.Dispersing & Anti-Crystallization Agent: Disperse solid particles and suppress undesirable crystal formation in canned seafood, beverages and other food formulations, maintaining uniform texture and preventing gritty or sandy mouthfeel.

3.Emulsifying & Stabilizing Agent: Stabilize food matrix and improve texture consistency in dairy products and processed cheese.

Applications

1.Food Formulations 

Canned Seafood & Frozen Seafood: Inhibit struvite crystal formation, prevent discoloration and maintain fresh color and texture of canned fish, shellfish and frozen seafood products.

Processed Meat & Poultry: Assist in water retention, reduce cooking loss and improve tenderness and yield of ham, sausage and processed meat products.

Beverages & Fruit/Vegetable Processing: Chelate metal ions to prevent turbidity, precipitation and enzymatic browning, maintain clear and stable product appearance.

Dairy & Processed Cheese: Stabilize system matrix and improve texture uniformity.

2. Industrial Applications

Applied in water treatment, detergent formulations and ceramic processing for metal ion control and dispersion performance.

3.Animal Feed

Occasionally used in special feed formulations, not as mainstream feed phosphate source.
