Sodium Acid Pyrophosphate Usage and Function.

Disodium pyrophosphate is an inorganic compound with the chemical formula Na2H2P2O7, which is commonly used in food additives such as fast leavening agents, moisture retention agents, quality improvers and so on. It is widely used in bread, cookies and other foods to keep the food moist and improve the quality. In addition, disodium pyrophosphate also has the ability to balance acid and alkali, often used in combination with calcium propionate, used for fermentation of pasta products, to extend shelf life.

Uses of Sodium Acid Pyrophosphate.

Disodium dihydrogen pyrophosphate is an inorganic compound with the chemical formula Na2H2P2O7, white crystalline powder, soluble in water and insoluble in ethanol. It is used in food industry as rapid fermentation agent, moisture retention agent, quality improver, for bread, cookies and other food production.

In addition, it is used as buffer, baking powder, feed additive, detergent and dyeing agent in fermentation industry. Disodium pyrophosphate needs to be used with caution because it has low toxicity, causes eutrophication of environmental waters, can be inhaled, ingested, and absorbed percutaneously, and people should not be exposed to it too much!

Characteristic of Sodium Acid Pyrophosphate.

Product method of Bulk Sodium Acid 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.
