In cooking, a leavening agent (/ ˈ l ɛ v ən ɪ ŋ /) or raising agent, also called a leaven (/ ˈ l ɛ v ən /) or leavener, is any one of a number of substances used in doughs and batters that cause a foaming action (gas bubbles) that lightens and softens the mixture.
Disodium pyrophosphate is a popular leavening agent found in baking powders. It combines with sodium bicarbonate to release carbon dioxide: Na 2 H 2 P 2 O 7 + NaHCO 3 → Na 3 HP 2 O 7 + CO 2 + H 2 O. It is available in a variety of grades that affect the speed of its action.
Hartshorn salt, also known as hartshorn, baker's ammonia, ammonium carbonate and ammonium bicarbonate is used as a leavening agent in baked goods in place of yeast, baking soda and baking powder. It was more popular in the 1700s and prior as a forerunner of the modern baking powder [ 7 ] but is still used today in traditional German, Swiss ...
Calcium dihydrogen phosphate is used in the food industry as a leavening agent, i.e., to cause baked goods to rise. Because it is acidic, when combined with an alkali carbonate ingredient, commonly sodium bicarbonate (baking soda) or potassium bicarbonate, it reacts to produce carbon dioxide and a salt. Outward pressure of the carbon dioxide ...

Acidulants can also function as leavening agents and emulsifiers in some kinds of processed foods. [1] Though acidulants can lower pH they differ from acidity regulators, which are food additives specifically intended to modify the stability of food or enzymes within it. Typical acidulants are acetic acid (e.g. in pickles) and citric acid.

The leavening agent either contains air bubbles or generates carbon dioxide. The heat vaporises the water from the inner surface of the bubbles within the dough. The steam expands and makes the bread rise.
