Which of the following is a function of yeast in baking?

• A. To add color
• B. To produce a light and porous structured loaf
• C. To create a chewy texture
• D. To add sweetness

Answer: (B)

Yeast plays a vital role in the baking process, particularly in the production of bread and other yeast-leavened products. One of its primary functions is fermentation, which produces carbon dioxide gas. This gas causes the dough to rise, creating a light and porous structure in the final baked product. As the dough ferments, the accumulation of gas bubbles expands and puffs up the dough, leading to a desirable airy texture in loaves of bread.

This light and porous structure enhances not only the texture but also the overall mouthfeel and enjoyment of the bread. The development of this structure is essential for achieving the characteristic qualities of many baked goods, making yeast an indispensable ingredient in baking.

The other options, while they may pertain to various aspects of baking, do not directly relate to the primary function of yeast. For example, color in baked goods is typically influenced by other factors such as sugars and Maillard reactions during baking, rather than yeast itself. Yeast does not inherently contribute to a chewy texture, which is more often a result of the types of flour used and dough handling techniques. Lastly, sweetness in baked goods comes mainly from added sugars or other sweeteners, not from the yeast, which actually consumes sugars during fermentation.
