Leavening agents

Substance that lead to expansion of doughs and batters by the release of gases within such mixtures, producing baked products with porous structure.

Agents such as air, steam, yeast, baking
powder and baking soda

Incorporation with air

Achieved by vigorous mixing incorporate
air bubbles producing foams

Examples

Biological Leavening Agent

Yeast

Chemical Leavening Agents

Baking Soda and Baking Powder

Single-acting baking powders

Containing tartaric acid or cream of tartar

Slow-acting baking powders

Containing phosphates

Double-acting baking powders

1st action

Gas is released when baking soda
in powder react with acidic liquid.

2nd action

Gas is released when batter is heated in oven or on a griddle

Vaporous Leavening Agent

Steam

Applications
