4.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.
5.Packing and storage
Packed in 25 kg,50kg,1000kg net bags, store at a cool, dry and well ventilated place.
6.Storage and Transport
kept in dry and ventilating place, load gently, avoid rain and breakage, no mixed with toxic matter.
