what is fermentation in baking
Fermentation is the process in which a substance breaks down into a simpler substance. Microorganisms like yeast and bacteria usually play a role in the fermentation process, creating beer, wine, bread, kimchi, yogurt and other foods. Fermentation comes from the Latin word fermentare, meaning âto leaven.â To make bread rise, you use a leavening agent to âwake upâ dry yeast by mixing it with water. The yeast then starts âeatingâ the sugar in the dough and off-gassing alcohol: thatâs fermentation.
