Study Notes
Fermentation Organisms
- Yeast and some bacteria undergo fermentation to produce ethanol and carbon dioxide.
Purpose of Fermentation
- The main purpose of fermentation in the production of bread and beer is to convert sugars into ethanol and carbon dioxide, which affects the texture, taste, and smell of the final product.
Fermentation in Bread Production
- During bread making, the ethanol produced during fermentation evaporates or is burned off during the baking process, leaving behind carbon dioxide, which causes the dough to rise.
Test your knowledge on fermentation and its role in the production of bread and beer. Learn about the equation for fermentation and how yeast converts glucose into ethanol and carbon dioxide. Discover why ethanol is evaporated during bread baking and how carbon dioxide gas creates bubbles in beer.
