What happens to yeast during the baking process?

• A. Yeast dies
• B. Yeast multiplies
• C. Yeast becomes dormant
• D. Yeast enhances flavor

Answer: (A)

During the baking process, yeast indeed dies due to the high temperatures associated with cooking. As bread or other baked goods are heated, the internal temperature of the dough rises significantly, eventually reaching a point where the heat becomes detrimental to the yeast cells. Typically, yeast begins to die at around 130°F (54°C) and is completely inactive above 160°F (71°C). The primary role of yeast in bread-making occurs during fermentation, where it converts sugars into carbon dioxide and alcohol, causing the dough to rise. Once the dough is placed in the oven and begins to bake, the fermentation process ceases as the yeast cells are killed by the heat. While the yeast is active, it also contributes some subtle flavors to the bread, but its main purpose is to leaven the dough. After the yeast has died, other processes take over, such as the Maillard reaction and caramelization, which develop the color and flavor of the crust. Understanding the fate of yeast during baking is essential for bakers, as it informs them about the different stages of dough development and the importance of temperature control in achieving optimal results.
