 SODIUM
ACID PYROPHOSPHATE(SAPP) |
Chemical formula : Na2H2P2O7
Molecular weight: 221.95
Properties:
White crystal powder;Relative density 1.86;Soluble
in water and insoluble in ethanol; If its aqueous solution is
heated together with diluted inorganic acid, it will be hydrolyzed
into phosphoric acid; It is hydroscopic, and when absorbing
humidity it will become into a product with hexa-hydrates; If
it is heated at a temperature above 220 , it will be decomposed
into sodium meta phosphate.
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 25 kg net WPP/PE bags. It must be stored
in places well ventilated and dry.
