Independent Chemical Offers Food Grade Sodium Acid Pyrophosphate (SAPP)
Sodium Acid Pyrophosphate (CAS #7758-16-9) is one of the many popular food-grade chemical ingredients offered by Independent Chemical Corporation. Sodium acid pyrophosphate (SAPP), also known as disodium pyrophosphate, is a white, water soluble solid with chemical formula Na2H2P2O7 that has many applications in the food industry. It is manufactured by partially neutralizing food-grade phosphoric acid with sodium hydroxide or sodium carbonate to form monosodium phosphate, which is then dehydrated at 250o C to form sodium acid pyrophosphate.
SAPP is commonly used as a leavening agent and is an important component of double acting baking powder as well as self-rising flour. Leavening agents provide air and volume to the baked good structure by reacting with baking soda to produce carbon dioxide gas, and also change the characteristics of the dough by forming ionic bonds with the starches and proteins in the dough. SAPP dissolves readily to form the anion pyrophosphate, which then interacts with the proteins in a baked good mixture to provide a moist texture. And it acts as a buffering agent for the dough in the pH range 7.3 to 7.5, which influences the color of the final product.
Other uses for SAPP include the following:
- Sequestrant/chelating agent in processed potatoes
- Emulsifying agent in cheese and other dairy products
- Peptizing agent in meat products
- Inhibitor agent in canned tuna
- Curing accelerator in processed meat and poultry products
