Product Description
Tetra Sodium Pyrophosphate (TSPP)
Properties
White powder; Soluble in water but insoluble in ethanol; Relative density 2.45g/cm3 and melting point 890ºC; Deliquescent in the open air. Its aqueous solution shows weak alkalinity and is stable at 70 ºC but will be hydrolyzed into di-sodium phosphate when boiled.
Application
Tetra Sodium pyrophosphate is used in the food industry as an emulsifying agent, nutrient and texturing agent in applications including: processed cheese, seafood products, hamburgers and meat. In food industry it is used as buffering agent, emulsifier, nutrition ingredients and quality improver.
Packaging
Plastic knit bag or kraft bag, net weight 25kg. Besides, we can pack the goods according to the requirement of the client.
