Introduction ( Disodium dihydrogen pyrophosphate CAS No.7758-16-9)
Sodium Acid Polyphosphate (SAPP) is used for various baking and leavening applications. Some food grade SAPP products have slower reaction rates which make them ideal for refrigerated doughs, cakes, muffins, pancake mixes and baking powders. Others are faster acting leavening agents in donuts and prepared mixes. SAPP is also used to maintain the natural white color of cooked potatoes.
Disodium Dihydrogen Pyrophosphate is easily soluble in water but insoluble in ethanol; Density at 2.45g/cm³ and melting point at 890ºC; Deliquescent in the open air.The water solution shows weak alkalinity and stable at 70ºC, but will be hydrolyzed into disodium phosphate when boiled.
Storage:
Kept in dry, cool, and shaded place with original packaging, avoid moisture, store at room temperature.

Function of Disodium dihydrogen pyrophosphate:
1.For Roasted foodstuff,SAPP is widely applied as a leavening agent to roast foodstuffs to control the fermentation speed.
2.For instant noodles,it is applied to reduce the time of rehydration of finished products and keep the noold chewy and complete;
3.For for biscuits and pastries,it is used to shorten the fermentation time, reduce the rate of product damage, loose and neat space, and extend the storage period.
