Tetrasodium Pyrophosphate Food Grade

Tetrasodium pyrophosphate, also called sodium pyrophosphate, sodium pyrophosphate anhydrous,tetra sodium diphosohate or TSPP, tetrasodium Pyrophosphate is white powder, or lumpy solid. Dissolves in water, easily soluble in acids, does not dissolve in mellow and ammonia. The aqueous solution assumes the alkali reaction. When it boils in the aqueous solution, it will hydrolyze into sodium hydrogen phosphate gradually. Can form into complex compound with alkali earth metal ion; Meets the Ag+ will form into white silver pyrophosphate. Sodium pyrophosphate decahydrate (Na4P2O7•10H2O) is colorless crystal of monoclinic system, with the specific gravity of 1.82, does not dissolve in alcohol, can form into complex with metallic ion. Easy to effloresce in dry air, when heat up into 100°C it will loss crystal water.

Tetrasodium Ptrophosphate Applications:

TSPP tetrasodium phosphate is used as a buffering agent, an emulsifier, a dispersing agent, and a thickening agent, and is often used as a food additive. Common foods containing sodium pyrophosphate include chicken nuggets, marshmallows, pudding, crab meat, imitation crab, canned tuna, and soy-based meat alternatives and cat foods and cat treats where it is used as a palatability enhancer. Tetrasodium pyrophosphate is also used in some common baking powders.

Storage and transport:

Tetrasodium pyrophosphate should be stored in a dry . ventilative and clean warthouse; kept away from moisture and hot, Furthermore, tetrasodium pyrophosphate should be stored separstely from poisonous Substances.
