Anwendungen & Verwendung
Verwenden
Ammonium dihydrogen phosphate is a general purpose food additive which is readily soluble in water. A 1% solution has a ph of 4.3–5.0. It is used as a dough strengthener and leavening agent in baked goods and as a firming agent and ph control agent in condiments and puddings. It is also used in baking powder with sodium bicarbonate and as a yeast food.
Herstellung & Synthese
synthetische
Preparative method similar to its dibasic salt; obtained by reaction of equimolar amounts of ammonia and phosphoric acid:NH3 + H3PO4 → (NH4)H2PO4.
