Sodium Pyrophosphate, chemical formula Na₄P₂O₇ and CAS 7722-88-5, is a vital multifunctional food phosphate widely applied in global food processing industry under export-standard specifications. Refined via complete purification and crystallization production process, the finished product is fine white crystalline powder with adjustable 60–120 mesh particle size, delivering rapid and complete dissolution without residual precipitates when mixed into water. Its core effective ingredient is controlled above 99.0%, with lead heavy metal limited within 2 ppm, water-insoluble impurities lower than 0.1%, and pH value of 1% aqueous solution stably maintained between 9.9 and 10.7, ensuring stable chemical activity and compliance with mainstream food additive regulations worldwide.

The core application value of sodium pyrophosphate originates from three prominent functions: water retention, metal chelation and quality improvement. In deep processing of meat products such as ham, sausage and frozen meat, it can effectively bind free water inside muscle tissue, reduce moisture loss during freezing, heating and storage, keep meat tender and juicy, and avoid shrinkage and hard texture. For seafood including fish, shrimp and shellfish, it inhibits protein decomposition, prevents discoloration and spoilage, extends shelf life and retains fresh elastic taste. In canned food production, it chelates trace metal ions that trigger oxidation and turbidity, stabilizing system homogeneity and improving finished product storage stability.

Our factory implements full-process quality inspection for every batch of sodium pyrophosphate, avoiding fluctuation of purity, particle size and pH value between batches. With stable production capacity and flexible packaging options, we support bulk container export and customized packaging service. Strictly matching global food-grade certification standards, our sodium pyrophosphate supplies reliable, cost-effective additive raw materials for meat processing enterprises, aquatic product processors and canned food manufacturers across international markets, winning long-term cooperative recognition for stable quality and competitive supply advantages.
