White Powder Na2H2P2O7 95% SAPP Food Additive
Properties:
White crystalline powder. The relative density is 1. 86 and the refractive index is 1.510. It is easily soluble in water (10g/100mL, 20°C) and ethanol. It is hygroscopic, the aqueous solution is acidic, and the pH of 1% water is 4-4.5. It is decomposed into sodium metaphosphate at 220°C. The aqueous solution and dilute mineral acid are heated to hydrolyze into phosphoric acid. Sodium acid pyrophosphate is slightly hygroscopic, forming six crystal hydrates after absorbing water. When heated to above 220°C, it decomposes to form sodium metaphosphate.
Applications:
Buffer, chelating agent, stabilizer, emulsifier, color improver in the food industry. For example, it can be used as a boil-resistant additive for instant noodles, a modifier for ham, sausage and flour, a leavening agent for pasta and biscuits, a flavoring agent for hamburger beef patties, a pH regulator for sausages, a color improver for vegetables, and water Chelating agent for products and canned food.
