The Mind-Boggling Science of Baking

Let’s dive into the fascinating world of baking and unravel the scientific marvels happening within your oven. When you combine yeast, flour, water, and a pinch of salt, the magic begins. Yeast, a minuscule organism, devours the sugars present in the dough, releasing carbon dioxide gas as a byproduct. This gas then gets trapped in the dough, causing it to rise and giving bread its signature airy texture.

A Battle of Yeast and Gluten

As the bread dough rises, the yeast engages in an epic battle against gluten. Gluten, which forms the structure of the bread, is a protein network created when flour mixes with water. Yeast ferments the sugars and, in the process, produces carbon dioxide gas, which inflates the gluten network. This continuous tug-of-war between yeast and gluten results in the final texture of the bread.
