Question

why dough Rises and swells when it is treated with the yeast

Answer 1

Hello mate,

Here is your answer,

This leavening agent makes bread dough rise through fermentation.

The yeast changes the sugar in the dough into carbon dioxide gas and ethanol (alcohol).

The gas, trapped in the dough, makes it rise; the alcohol produced during fermentation evaporates during baking.

HOPE THIS HELPS UU :)

AND STAY BLESSED.
