Bread Making and Yeast Processes

The video explores the chemistry behind bread making, focusing on the often-overlooked role of the bun in a cheeseburger. It explains the process of making bread, starting with the variety of flours available and their composition. The video details how mixing flour with water and yeast leads to gluten formation, which gives bread its structure. It highlights the importance of kneading in developing gluten and how yeast ferments the dough, producing carbon dioxide that causes the dough to rise. The baking process is explained, showing how heat affects yeast activity and contributes to the bread's final texture.
