What is the purpose of using yeast in the dough formula?

• A. To improve texture
• B. To enhance flavor only
• C. To act as a leavening agent
• D. To increase dough weight

Answer: (C)

Yeast plays a crucial role in bread making primarily as a leavening agent. When yeast is added to the dough, it ferments the sugars present, producing carbon dioxide gas and alcohol as byproducts. The carbon dioxide gas gets trapped in the dough's structure, causing it to rise and create the characteristic airy texture of baked bread. This leavening action is essential for achieving the desired volume and lightness in the final product. While yeast can contribute to the flavor of the bread, its primary function in the dough formula is to cause fermentation, leading to the necessary rise. Improving texture and increasing dough weight might occur as secondary effects, but they are not the main purposes of incorporating yeast. Therefore, recognizing yeast as a leavening agent is essential for understanding its importance in the bread-making process.
