Thus the contamination usually occurs when cooling is done as well as during packing, handling and from the environment.

Why the dough rises and makes the bread spongy?

Yeast in bread making Yeast is used for the leavening of bread. Yeast uses the sugars and oxygen in dough to produce more yeast cells and carbon dioxide gas. This is called multiplication. The carbon dioxide makes the dough rise which gives the bread a light and spongy texture.
