Leavening Agents

Leavening agents are substances that cause doughs and batters to rise, creating a lighter and softer texture. They can be chemical, such as baking soda or baking powder, or biological, like yeast. Chemical leaveners produce carbon dioxide gas when mixed with liquid and/or heat, while yeast consumes sugars and produces carbon dioxide and alcohol.

Manufacturers add leavening agents to baked goods like bread, cakes, cookies, and muffins to make them expand and become fluffy. They are essential for achieving the desired airy structure and texture in a wide variety of bakery products. Common examples include baking soda, baking powder, and yeast.

Leavening agents like baking soda and baking powder are generally recognized as safe (GRAS) by the FDA when used as intended. Yeast is a common food ingredient with no specific regulatory concerns. International bodies like JECFA have evaluated various leavening agents. At typical dietary levels, they are not associated with adverse health effects.
