Uses:
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.
Packing and storage:
Packed in 25kg,50kg,1000kgnet bage,20mt/FCL.Store at a cool, dry and well ventilated place.
