Product description:
Commodity: Sodium Acid Pyrophosphate
CAS#:7758-16-9
Formula: Na2H2P2O7
Structural Formula:
Uses: Play a role of buffering agents, fermentation agents, modifiers, emulsifiers, nutritional agents, canned preservatives in food. Application: 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 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.
