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.


  • As a leavening agent it is applied to roast food stuffs 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.
  • We manufacture Food Grade SAPP.
  • It is available in 25 kg HDPE bags.
