Applications OF SAPP Sodium Acid Pyrophosphate
As a leavening agent, SAPP Sodium Acid Pyrophosphate 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.
