Description of DSPP
Disodium pyrophosphate or sodium acid pyrophosphate is an inorganic compound consisting of sodium cations and pyrophosphate anion. It is a white, water-soluble solid that serves as a buffering and chelating agent, with many applications in the food industry. When crystallised from water, it forms a hexahydrate, but it dehydrates above room temperature. Pyrophosphate is a polyvalent anion with a high affinity for polyvalent cations, e.g. Ca2+.
Disodium pyrophosphate is produced by heating sodium dihydrogen phosphate:
2 NaH2PO4 → Na2H2P2O7 + H2O

What is NA4P2O7?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is DSPP which has developed particularly rapidly in recent years. Do you know about DSPP?
- The official answerDisodium pyrophosphate is an inorganic substance with the chemical formula Na2H2P2O7, a white crystalline powder with a relative density of 1.862, which is heated to 220°C and decomposed into sodium metaphosphate. Soluble in water, can form a chelate with Cu2+, Fe2+, aqueous solution and dilute sulfuric acid dilute inorganic acid heating hydrolysis into phosphoric acid. The source and method of production are sodium dihydrogen phosphate heated to 200 ℃ dehydration; or in phosphoric acid by adding sodium carbonate and then heated to 200 ℃ after dehydration.
What’s the application of NA4P2O7?
Used as baking powder, used for baked goods, control the fermentation speed, improve the production intensity; used for instant noodles, reduce the finished product rehydration time, not sticky and not rotten. Used for cookie and pastry, shorten the fermentation time, reduce the product breakage rate, loosen the gap neatly, and can extend the storage period.
