Properties: Disodium dihydrogen pyrophosphate, also named sodium acid pyrophosphate, is a white powder or granular. Relative density 1.86g/cm3; Soluble in water and insoluble in ethanol; If its aqueous solution is heated together with diluted inorganic acid, disodium dihydrogen pyrophosphate will be hydrolyzed into phosphoric acid; It is hygroscopic, and when absorbing humidity it will become into a product with hexahydrate; If sodium acid pyrophosphate is heated at a temperature above 220℃, it will be decomposed into sodium metaphosphate.

Usage: Disodium dihydrogen pyrophosphate, also known as sodium acid pyrophosphate (SAPP), has several applications in various industries. Some of the common applications include:
1. Food industry: Disodium dihydrogen pyrophosphate is widely used as a food additive in bakery products, such as bread, cakes, and pastries. It acts as a leavening agent, helping to create a lighter texture by releasing carbon dioxide gas during baking. It is also used in biscuits and cakes to reduce fermenting time and extend product storage. When applied to instant noodles, it can shorten water resetting time and avoid the stickiness and mushiness of the noodles.
2. Food processing: Disodium dihydrogen pyrophosphate is used as a pH regulator, emulsifier, and texture modifier in various processed food products. It helps control acidity or alkalinity, improve shelf life, and enhance texture and appearance.
3. Meat industry: Disodium dihydrogen pyrophosphate is utilized in the meat industry as a meat tenderizer and as a color stabilizer in cured meat products, such as sausages and hams. It helps improve water retention and maintain desirable color.
4. Dental products: Disodium dihydrogen pyrophosphate is found in toothpaste and mouthwash. It serves as a tartar control agent, helping to prevent the formation of tartar or dental calculus on teeth.
5. Water treatment: Disodium dihydrogen pyrophosphate is used in certain water treatment processes, particularly in the prevention of scale formation. It can help inhibit the deposition of calcium and magnesium ions, reducing the potential for scaling in pipes and equipment.
6. Industrial applications: Disodium dihydrogen pyrophosphate is employed in various industrial processes, such as metal treatment and detergent formulations. It assists as a dispersing agent, chelating agent, and emulsifier in these applications.
