Product Introduction
What is sodium hexametaphosphate? Sodium Hexametaphosphate, widely abbreviated as SHMP, is a water-soluble inorganic polyphosphate. It appears as a white, free-flowing powder or granule, and its chemical formula is written as (NaPO₃)₆. In the food industry it is listed under the code E452(i) and is valued as a multi-purpose phosphate ingredient.
Buyers also know it as sodium polymetaphosphate, glassy sodium phosphate, or by the trade name “Calgon” used for water-softening products. As a sodium phosphate blend with strong metal-binding ability, SHMP keeps minerals from reacting with other ingredients, stabilizes texture and holds moisture in the product.
As a professional China manufacturer, supplier and exporter of food-grade phosphates, WEHENGFOOD supplies Sodium Hexametaphosphate with consistent quality and reliable export documentation to food processors, distributors and traders worldwide.

Key Functions of SHMP
- Sequestration (metal-ion binding): SHMP captures calcium, magnesium, iron and other metal ions, preventing discoloration, cloudiness and mineral-related off-flavors.
- Water retention: It helps meat and seafood hold on to natural moisture during processing, cooking and freezing, which lowers drip and cooking loss.
- Emulsion stabilization: It supports a smooth, uniform blend of fat and water, which is important for sausages, processed cheese and sauces.
- Protein dispersion: SHMP loosens and solubilizes muscle and milk proteins, improving binding and texture.
- Viscosity and texture control: It adjusts the thickness of sauces and other liquid foods, giving a more consistent mouthfeel.
- Quality protection: By keeping texture, color and flavor stable, it helps maintain product freshness and shelf appeal during storage.
Sodium Hexametaphosphate Uses in Food
The uses of sodium hexametaphosphate span many food categories. Typical applications of sodium hexametaphosphate in food include:
- Meat products: Burgers, ham, sausages, hot dogs and other processed meats, where SHMP improves juiciness, bite and slicing quality.
- Seafood: Peeled shrimp, canned tuna and smoked fish, where it retains moisture and helps preserve color and firmness.
- Sauces and vegetables: Tomato sauce and other processed vegetable products, where it increases viscosity and reduces color changes caused by metal ions.
- Dairy and processed cheese: Acts as an emulsifying salt and stabilizer to keep texture uniform.
- Beverages and juices: Prevents mineral-induced haze and sediment, keeping drinks clear.
- Egg products, jams and desserts: Supports consistent texture and appearance.
Beyond food, SHMP is also used in water treatment, ceramics, and detergent applications as a dispersant and scale inhibitor.

FAQ
Q1: What is sodium hexametaphosphate?
Sodium hexametaphosphate (SHMP) is a water-soluble polyphosphate with the formula (NaPO₃)₆ and CAS No. 10124-56-8. In food it is labeled E452(i) and used as a sequestrant, emulsifier and moisture-retention agent. WEHENGFOOD is a China manufacturer, supplier and exporter of food grade SHMP.
Q2: What is sodium hexametaphosphate used for in food?
Common sodium hexametaphosphate uses include meat products (ham, sausages, burgers), seafood (shrimp, canned tuna), tomato sauce, processed cheese and beverages. It improves texture, water retention, viscosity and color stability.
Q3: How does SHMP improve meat and seafood quality?
SHMP binds metal ions, helps dissolve proteins and stabilizes the fat-water emulsion. This means less drip loss, higher yield and a firmer, juicier bite.
Q4: Is Calgon the same as SHMP?
Calgon is a trade name long associated with water-softening products based on sodium hexametaphosphate. The ingredient itself is SHMP, sold under many brand names.
Q5: What is the difference between SHMP, sodium phosphate and sodium citrate?
SHMP is a polyphosphate with strong metal-binding and water-retention power. Sodium phosphate is a broader group, mainly used for pH adjustment. Sodium citrate is a citric acid salt used as a buffer and emulsifying salt.
