Ammonium bicarbonate A white powder made for use as a leavening agent, which is added as an ingredient when preparing many different types of baked goods that will have thin shells or crusts such as puff pastries, flat breads, crackers, and some cookies. Ammonium Bicarbonate is typically used with smaller baked goods that can quickly disperse and evaporate the ammonia gas as it builds up within the baked item. During the baking process, an ammonia aroma may be present, but it will not remain and will not be noticed in the baked goods when they are eaten. The result of using Ammonium Bicarbonate is a baked good that will have a light, airy, crispy, and somewhat fluffy texture.
Sodium acid pyrophosphate (SAPP 28) It is white powder, soluble in water, insoluble in ethanol. Water solution is alkaline. Developed specifically for use in canned, refrigerated biscuit dough. The CO2 release is extremely low enabling dough to be held for long periods, even at above normal temperatures.
Used as a leavening agent in Bakery, doughnuts, cakes and other prepared mixes. Frequently used with slower-acting sodium acid pyrophosphate to increase reaction rates Disodium Pyrophosphate 28 (sodium acid pyrophosphate) is used as a slow reacting aerator acidulate in conjunction with sodium bicarbonate.
Sodium bicarbonate Sodium bicarbonate, referred to as "baking soda", is primarily used in cooking (baking), as a leavening agent. It reacts with acidic components in batters, releasing carbon dioxide, which causes expansion of the batter and forms the characteristic texture and grain in pancakes, cakes, quick breads, soda bread, and other baked and fried foods. Acidic compounds that induce this reaction include phosphates, cream of tartar, lemon juice, yogurt, buttermilk, cocoa, vinegar, etc. Sodium bicarbonate can be substituted for baking powder provided sufficient acid reagent is also added to the recipe. Many forms of baking powder contain sodium bicarbonate combined with calcium acid phosphate, sodium aluminum sulphate or cream of tartar.
