    Product Overview:

    Disodium Pyrophosphate is an inorganic compound with the chemical formula Na2H2P2O7, a white crystalline powder, soluble in water and insoluble in ethanol. The compound is mainly used as a rapid leavening agent, moisture retention agent, quality improver for baked goods such as bread, cookies and meat.
    Disodium pyrophosphate has low toxicity, it will cause eutrophication to the water bodies of the environment, it can be inhaled, ingested, and absorbed percutaneously by the human body, and people should not be exposed to too much of it, otherwise it will be harmful to the human body, especially to the skin and eyes.

    Sodium pyrophosphate Raw materials Powder Details

    Sodium pyrophosphate Powder Usage and Synthesis.

    Disodium dihydrogen pyrophosphate is an inorganic compound with the chemical formula Na2H2P2O7, which is mainly used as a fast leavening agent, moisture retention agent, quality improver, and is used in bread, cookies and other foods. In practice, disodium pyrophosphate is usually combined with calcium propionate to balance the pH of fermented dough. In addition, disodium pyrophosphate is also able to form complexes with magnesium and iron ions.

    Sodium pyrophosphate Powder

    Uses of Sodium pyrophosphate.

    It is a texture improver, which has the effect of increasing the complex metal ions, pH value and ionic strength of the food, thus improving the adhesion and water-holding property of the food. China's regulations can be used in soda cookies, the maximum use of 3.0g/kg; the maximum use of 1.0-3.0g/kg in bread.

    Disodium pyrophosphate can be used as baking powder, used in baked food, control the fermentation speed, improve the production intensity; used in instant noodles, reduce the rehydration time of the finished product, non-stick and non-rotten. Used in cookies and pastries, it can shorten the fermentation time, reduce the breakage rate of the product, loosen the gaps neatly and prolong the storage period.

    It can be used as fast fermentation agent, moisture retention agent and quality improvement agent for bread, cookies and other baked foods, meat and aquatic products.

    Sodium pyrophosphate

    Characteristic of Sodium pyrophosphate.

    Disodium pyrophosphate is a white monoclinic crystalline powder or molten solid. Relative density 1.86, soluble in water, insoluble in ethanol. Aqueous solution and dilute inorganic acid is hydrolyzed to phosphoric acid when heated.

    Acid sodium pyrophosphate is slightly hygroscopic, after absorbing water to form six crystalline hydrates. When heated to 220 ℃ above the decomposition of sodium metaphosphate. When used as a bulking agent, it can contain an appropriate amount of aluminum and/or calcium salts to control the reaction rate.

    Sodium pyrophosphate raw materials

    Product Method of Bulk Sodium pyrophosphate Powder.

    Drying polymerization two-step method will be food-grade soda ash added to the neutralizer, heated under stirring to dissolve, and then add food-grade phosphoric acid for neutralization reaction, control the reaction endpoint Ph = 4 ~ 4.4, the generation of sodium dihydrogen phosphate, the solution will be filtered at 70 ~ 80 ° C, the filtrate evaporation and concentration, cooling crystals, centrifugal separation, drying at 95 ° C dehydrated to become anhydrous sodium dihydrogen phosphate. Then sent to the box-type polymerization furnace heating melt polymerization, control the material temperature at 140 ~ 200 ℃ for polymerization, the conversion of acid sodium pyrophosphate after crushing and packaging, the production of disodium pyrophosphate.
