                                Disodium dihydrogen pyrophosphate, also known as SAPP or E450(i), is a key ingredient in many processed foods, acting as a leavening agent. This white, crystalline powder is an inorganic compound, with its synthesis fundamentally relying on the heating and dehydration of sodium dihydrogen phosphate.
