Sodium Acid Pyrophosphate descriptions
Sodium acid pyrophosphate is monoclinic, white crystalline powder. Density 1.86. Practically insoluble in alcohol, soluble in water. Hydrolyzes to orthophosphate on heating in acid medium. Hygroscopic, forms hexahydrate in damp air. Decomposes to metaphosphate at above 220℃.
Disodium pyrophosphate is also found in hash browns (frozen) to keep the color of the potatoes from fading.
If its aqueous solution is heated together with diluted inorganic acid, sodium acid pyrophosphate will be hydrolyzed into phosphoric acid. sodium acid pyrophosphate is hydroscopic, and when absorbing humidity it will become into a product with hexa-hydrates. If sodium acid pyrophosphate is heated at a temperature above 220°C, it will be decomposed into sodium meta phosphate.
Sodium Acid Pyrophosphate Applications
Disodium pyrophosphate or sodium acid pyrophosphate is a buffering and chelating agent used in canned seafood, as a scald agent in poultry and pork. As a sequesterant in potato products, sodium acid pyrophosphate is used to aid leavening in baked goods.
In leather treatment, sodium acid pyrophosphate can be used to remove iron stains on hides during processing. Sodium acid pyrophosphate can stabilize hydrogen peroxide solutions against oxidation. Sodium acid pyrophosphate can be used for cleaning with sulfamic acid in some dairy applications. In petroleum production, sodium acid pyrophosphate can be used as a dispersant in oil well drilling muds.
Sodium acid pyrophosphate acts as a buffer, leaven, modifier, emulsifier, nutrient and canning preservative in foods. Oil drilling, detergent, chemical stabiliser. Sodium acid pyrophosphate is used as rapid ferment agent, quality improver in food industry. Applied to acid component of synthetic swelling agent, such as, bread, cake. Builted with other phosphates can be applied to water retention of meat product, such as canned meat, cooked ham, meat can and instant noodles.
As a leavening agent, sodium acid pyrophosphate is applied to roast foodstuffs to control the fermentation speed. When applied to instant noodles, sodium acid pyrophosphate can shorten water resetting time and avoid stickiness and mushiness of the noodles; When applied to crackers or cakes, sodium acid pyrophosphate may shorten fermentation time, lower the breakage, make the porous space in good order and therefore lengthen the shelf life.
