Quality Improver Inorganic Chemicals Sodium Pyrophosphate CAS 7758-16-9 Rapid Fermentation Agent Moisture Retainer
Introduction:
Disodium dihydrogen pyrophosphate has the appearance of white monoclinic crystalline powder or molten solid. Relative density is 1.86. It is soluble in water, but insoluble in ethanol. When the aqueous solution is heated with dilute inorganic acid, it is hydrolyzed into phosphoric acid. Sodium acid pyrophosphate is slightly hygroscopic and forms six crystalline hydrates after absorbing water. It decomposes to form sodium metaphosphate when heated to above 220°C. When used as a leavening agent, it may contain an appropriate amount of aluminum salt and/or calcium salt to control the reaction rate.
Uses:
Disodium dihydrogen pyrophosphate can be used as baking powder, used in baking food, controlling the fermentation speed and improving production intensity; used in instant noodles, shortening the rehydration time of finished products, and preventing them from sticking or rotting. Used in biscuits and pastries, it can shorten the fermentation time, reduce the product breakage rate, make the gaps loose and neat, and extend the storage period.
