3.Characters
White monoclinic crystalline powder or molten solid; relative density: 1.86; dissolving in water, but not in ethanol; aqueous solution and dilute inorganic acid is heated to hydrolysis into phosphoric acid; Sodium Acid Pyrophosphate is slightly hygroscopic with forming absorbent after six crystalline hydrate; This product is decomposedto sodium metaphosphate when heated to above 220 ℃; It may contain appropriate amounts of aluminum and / or calcium to control the rate of reaction when used as a leavening agent.
4.Food Usage
Disodium pyrophosphate is a popular leavening agent found in baking powders. It combines with sodium bicarbonate to release carbon dioxide:
Na₂H₂P₂O₇ + NaHCO₃ → Na₃HP₂O₇ + CO₂ + H₂O
It is available in a variety of grades that affect the speed of its action. Because the resulting phosphate residue has an off-taste, SAPP is usually used in very sweet cakes which mask the off-taste.
Disodium pyrophosphate and other sodium and potassium polyphosphates are widely used in food processing; in the E number scheme, they are collectively designated as E450, with the disodium form designated as E450(a). In the United States, it is classified as generally recognized as safe (GRAS) for food use. In canned seafood, it is used to maintain color and reduce purge during retorting. Retorting achieves microbial stability with heat. It is an acid source for reaction with baking soda to leaven baked goods.In baking powder, it is often labeled as food additive E450. In cured meats, it speeds the conversion of sodium nitrite to nitrite (NO₂−) by forming the nitrous acid (HONO) intermediate, and can improve water-holding capacity. Disodium pyrophosphate is also found in frozen hash browns and other potato products, where it is used to keep the color of the potatoes from darkening.
Disodium pyrophosphate can leave a slightly bitter aftertaste in some products, but "the SAPP taste can be masked by using sufficient baking soda and by adding a source of calcium ions, sugar, or flavorings."
