Introduction

Sodium hexametaphosphate (SHMP) is a condensed polyphosphate produced by melting monosodium phosphate at high temperatures followed by rapid quenching to form a glassy solid. It consists of polymeric chains of phosphate units with an average chain length of 10 to 25 units.

SHMP is one of the most widely used food-grade polyphosphates due to its exceptional sequestering, dispersing, and water-softening properties. In beverages, it prevents calcium and magnesium precipitation that causes turbidity and scale formation. SHMP also functions as an effective emulsifier, texturizer, and moisture-binding agent in meat, dairy, and seafood processing.

Uses

  • Sequestrant and water softener in beverage processing
  • Moisture retention and texture improver in processed meats
  • Emulsifying salt in processed cheese and cheese products
  • Scale inhibitor in water treatment for food processing plants
  • Dispersant and stabilizer in powdered milk and creamers
  • Cryoprotectant in frozen shrimp, fish, and seafood products
