Product Description

Product Description

Disodium Pyrophosphate (DSPP) is a white, odorless, crystalline powder or granular material with high solubility in water. It forms an acidic aqueous solution (pH ~3.5-4.5) and acts as a versatile chelating agent, buffering agent, leavening agent, and stabilizer. Synthesized by heating sodium dihydrogen phosphate, DSPP is widely utilized across food, industrial, and technical sectors due to its functional properties.

Product Application

Food Industry

Baked Goods: Serves as a leavening agent in cakes, bread, and pastries by reacting with baking soda to release CO2, ensuring even texture and volume.
Meat & Seafood Processing: Enhances moisture retention in cured meats (e.g., sausages, ham) and seafood, improving tenderness and shelf life.
Dairy Products: Acts as an emulsifier in cheese spreads and processed cheeses, preventing oil separation.
Beverages: Functions as a preservative and pH regulator in canned juices and soft drinks.
Potato Products: Prevents discoloration in potato-based snacks (e.g., fries, chips) by inhibiting enzymatic browning.

Industrial Applications

Water Treatment: Prevents scale formation in boilers and cooling systems by sequestering calcium and magnesium ions.
Detergents & Cleaners: Enhances cleaning efficiency in household/industrial products by softening water and stabilizing bleaches.
Metal Surface Treatment: Used in electroplating and metal cleaning to remove oxides and improve coating adhesion.
Textile & Petroleum: Acts as a dye-fixing agent in textiles and a dispersant in oil drilling fluids.
