Food Additive Sodium Hexametaphosphate - High-Quality Water Softener for Food Applications

Sodium Hexametaphosphate (NaPO₃)₆, a high-purity polyphosphate compound, is a versatile food additive acclaimed for its superior water-softening, sequestering, and emulsifying capabilities. With ≥98% purity (compliant with FCC/USP standards), this white granular powder effectively binds calcium, magnesium, and heavy metal ions, preventing scale formation, improving texture, and extending shelf life in processed meats, dairy, beverages, and canned goods. Its robust ion-chelating capacity and pH stability make SHMP indispensable for manufacturers prioritizing process efficiency, product consistency, and compliance with global food safety regulations.
