What is the leavener used in yeast dough?

• A. Baking powder
• B. Soda
• C. Yeast
• D. Egg whites

Answer: (C)

Yeast is the primary leavener used in yeast dough because it is a living organism that ferments when mixed with sugars and moisture. During fermentation, yeast produces carbon dioxide gas, which gets trapped in the dough’s gluten structure. This process causes the dough to expand and rise, leading to a light and airy texture in baked goods such as bread, rolls, and other yeast-leavened pastries.

In contrast to other leaveners such as baking powder, which is a chemical leavener, or baking soda, which requires an acid to activate it, yeast relies on fermentation and fermentation time to create rise. While egg whites can contribute to leavening in some recipes by incorporating air when beaten, they do not undergo the same fermentation process that yeast does. Thus, yeast is the unique leavener responsible for the distinctive qualities of yeast dough.
