Sodiaum Acid Pyro Phosphate
Specifications
Chemical Name Sodium Acid Pyrophosphate Chemical Formula Na2H2P2O7 CAS CODE 7758-16-9 Assay (as Na2H2P2O7) ≥ 95%/td> MOLECULAR WEIGHT 221.95 Phosphate (P2O5) ≥ 63-64% PH Value 3.5-4.5 Water Insoluble ≤ 1% Flouride (as F) ≤ 0.005% Heavy Metal (as Pb) ≤ 0.0001% Properties:
White powder or granular; Relative density 1.86g/cm3;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°C, it will decompose into sodium meta phosphate.
Uses:
1. As a leavening agent it is applied to roast food stuffs to control the fermentation speed. 2. When applied to instant noodles, it can shorten water resetting time and avoid stickiness and mushiness of the noodles. 3. 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. We manufacture Food Grade SAPP. It is available in 25 kg HDPE bags.
