Properties:White powder, soluble in water, insoluble in alcohol, relative density 2.45, melting point 890 degrees C, water solution is weakly alkaline, easy to moisture solution in the air, water solution at 70 degrees C is more stable, boiling water is hydrolysised into DI SODIUM PHOSPHATE
Application: In food processing as a quality improver, emulsified dispersant, Buffering agent, chelating agent, etc., with the generality of shrinking phosphate, chelating, dispersion is obvious, can resist flocculation, can prevent fat oxidation, casein proliferation and other effects. When the PH value is high, it has the effect of inhibiting food corruption and fermentation. Mainly used in meat and aquatic products processing, can improve water holding, to maintain fresh meat, stable natural pigment. Can also be used in starch manufacturing, etc., and many with other condensed phosphate compound use. TSPP generally adds 0.5-3 in food processing, with a maximum addition of 3% in aquatic product processing。
Package :25 kgs bag,two layer inner bag, outside bag is WPP bag。
