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℃, it will be decomposed into sodium meta phosphate.
Application: Used as a fast fermentation agent, quality improver, puffer, Buffering agent, chelating agent, rehydration agent and adhesive in food processing. Acid ingredients for synthetic puffers such as bread, pastries, CO2 have a longer generation time, suitable for less moisture-rich grilled foods (such as pancakes), and other phosphate compounding can be used for cheese, lunch meat, ham, meat products and aquatic products processing water retention agent, instant noodles compounding agent. In food processing generally add 0.5-3‰, in the processing of aquatic products to add a maximum amount of 1%.
Package: 25 kgs bag,two layer inner bag, outside bag is WPP bag。
