Sodium Acid pyrophosphate (SAPP)
Chemical formula: Na2H2P2O7
Molecular weight: 221.95
Properties: white powder or white particles, relative density 1.86, soluble in water, insoluble in ethanol, water solution and inorganic acid were hydrolyzed into phosphoric acid by heating, hyscopicity, water absorption formed six crystal hydrate, heating to more than 220℃ decomposition to generate sodium metaphosphate.
USES: used as leavening agent, used for baking food, control fermentation speed;For instant noodles, reduce the rehydration time of finished products, not stick not rotten;It can shorten the fermentation time, reduce the damage rate of the finished product, and prolong the storage life.
Packing: woven with inner plastic, net weight 25kg, 50kg and 1000kg per bag, stored in a ventilated and dry place.
