Yeast
Yeast is the microorganism that, when incorporated into dough, generates carbon dioxide (CO2), allowing the dough to increase in volume. To achieve this, yeast requires sugars, which it transforms into CO2 and ethanol. While ethanol evaporates during baking, CO2 remains trapped in the dough, giving it a spongy texture, provided that the dough has the ability to retain this gas, which, in most cases, depends on the gluten network. The yeast used in baking belongs to the Saccharomyces cerevisiae genus….
