Question

How does the bread become spongy?

Answer 1

Fermentation:

1. Fermentation is an anaerobic process that converts sugars into simpler substances.
2. The fermentation that occurs in the dough is known as homolactic fermentation.

Bread becomes spongy due to:

1. Yeast is added to the bread dough.
2. The yeast reproduces rapidly in the dough.
3. It ferments the sugar present in the dough into carbon dioxide.
4. The carbon dioxide fills the dough and causes it to increase in volume.
5. This makes the dough rise and the bread thus appears spongy.
6. Upon baking, the bubbles break due to heat and the bread appears fluffy.
