Aqueous solutions of ammonium bicarbonate (0.01 – 0.1 M) have pH around 8, the optimal pH for trypsin activity. Metals and arsenic specifications revised at the 63rd JECFA (2004). It is uniquely suited to the leavening of low finished product moisture baked goods like crackers and cookies. Unfortunately, ammonium bicarbonate tends to induce protein unfolding during ESI. The stabilizing property of Ammonium Bicarbonate allows maintaining the ideal physicochemical properties in a food; either preserving a food in a homogeneous state or by maintaining / intensifying a color. Ammonium carbonate is a very nice buffer from pH 9-10 because you are at the pKa of both the ammonium and the carbonate. Choose the buffer species you want to use. What is Ammonium Bicarbonate An inorganic compound, it is used in the food industry as a raising agent for flat baked goods, such as cookies and crackers. On exposure to air it becomes opaque and is finally converted into porous lumps or a white powder of ammonium bicarbonate because of the loss of ammonia and carbon dioxide. Ammonium bicarbonate (NH 4 HCO 3) (50 mM, pH 7.8) . With such a characteristic, several existing food formulations already contain and use sodium bicarbonate as a pH buffer.
