Description OF FOODCHEM STPP Sodium Tripolyphosphate Food Grade Granular STPP Sodium Tripolyphosphate Assay:94%;White powder/granule Type:FOOD Grade,Tech Grade 25 KG/BAGS Shelf life:2 years STPP or sodium triphosphate is an inorganic compound with formula Na5P3O10. STPP,Sodium Tripolyphosphate  is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. Sodium tripolyphosphate is produced by heating a stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4, under carefully controlled conditions.    Specification OF  FOODCHEM 94% Sodium Tripolyphosphate STPP Granular STPP,Sodium Tripolyphosphate Food Grade  ITEM STANDARD ASSAY (%) (Na5P3O10) 95 MIN APPEARANCE WHITE GRANULAR P2O5 (%) 57.0 MIN FLUORIDE (PPM) 10MAX CADMIUM (PPM) 1 MAX LEAD (PPM) 4 MAX MERCURY (PPM) 1 MAX ARSENIC (PPM) 3 MAX HEAVY MENTAL (AS PB) (PPM) 10 MAX CHLORIDES (AS CL) (%) 0.025 MAX SULPHATES (SO42-) (%) 0.4 MAX SUBSTANCES NOT DISSOLVED IN WATER (%) 0.05 MAX PH VALUE (%) 9.5 - 10.0 LOSS ON DRYING 0.7% MAX HEXAHYDRATE 23.5% MAX WATER-INSOLUBLE SUBSTANCES 0.1% MAX HIGHER POLYPHOSPHATES 1% MAX   STPP,Sodium Tripolyphosphate Tech Grade Items Standards Assay (%) (Na5P3O10) 94%MIN Appearance WHITE GRANULAR P2O5 (%) 57.0 MIN Bulk density 0.4~0.6 Iron 0.15%MAX Temperature rise 8~10 Polyphosphate 0.5 MAX PH value(%) 9.2 - 10.0 Ignition loss 1.0% MAX 20mesh through  ≥90%   Application OF STPP Sodium Tripolyphosphate In Food: The uses of stpp include using it as a preservative. Sodium Tripolyphosphate STPP can be used to preserve foods such as red meats, poultry, and seafood, helping them to retain their tenderness and moisture. Pet food and animal feed have been known to be treated with Sodium tripolyphosphate stpp , serving the same general purpose as it does in human food.  In Tech: The majority of STPP Sodium tripolyphosphate is consumed as a component of commercial detergents. Other uses include "ceramics (increase viscosity of the glazes upto a certain limit), leather tanning (as masking agent and synthetic tanning agent - SYNTAN), anticaking, setting retarders, flame retardants, paper, anticorrosion pigments, textiles, rubber manufacture, fermentation, antifreeze."STPP is used as a polyanion crosslinker in polysaccharide based drug delivery.
