Sodium acid pyrophosphate white powder, relative density 1.86, insoluble in water, insoluble in ethanol, aqueous solution is heated with dilute acid hydrolysis of phosphoric acid, Sodium acid pyrophosphate hygroscopic, absorbing water to form six crystalline hydrate, Sodium acid pyrophosphate heated to above 220 ℃ partial decomposition of sodium.
Sodium acid pyrophosphate as fermentation agent, buffer, improvers, emulsifiers, nutrients, canned food preservatives, for baking food, Sodium acid pyrophosphate as a leavening agent in baked foods sodium sodium to control the fermentation speed, for instant noodles, reduce product time and avoid complex viscosity of water. Sodium acid pyrophosphate pastry for biscuits, shorten the fermentation time, reduce product breakage, loose gap neatly, Sodium acid pyrophosphate extended storage period. Sodium acid pyrophosphate packaging: 25 kg net paper bags or paper-plastic bags. Sodium acid pyrophosphate storage and transportation: Stored in dry, ventilated; Sodium acid pyrophosphate to prevent rain and moisture during transportation, loading and unloading should be with care, to prevent the packaging is damaged; stored separately from poisonous substances when.
