Disodium dihydrogen pyrophosphate, white monoclinic crystalline powder or molten solid. The relative density is 1.86. Soluble in water, insoluble in ethanol. Water solution and dilute inorganic acid are hydrolyzed to phosphoric acid when heated. Acid sodium pyrophosphate is slightly hygroscopic with Chemicalbook and forms six crystal hydrates after absorbing water. When heated to above 220 ℃, it will decompose to generate sodium metaphosphate. When used as a bulking agent, it can contain an appropriate amount of aluminum salt and/or calcium salt to control the reaction rate.
As a leavening agent, it is applied to roast foodstuffs to control the fermentation speed; When applied to instant noodles, it can shorten water resetting time and avoid the stickiness and mushiness of the noodles. When applied to crackers or cakes, it may shorten fermentation time, lower the breakage, make the porous space in good order and therefore lengthen the shelf life.
