A » Sugar acts as food for yeast in bread making, promoting fermentation and enhancing dough rise. It accelerates yeast activity by providing a readily available energy source, leading to the production of carbon dioxide and ethanol. This process results in a lighter, airy bread texture. However, excessive sugar can dehydrate yeast cells, inhibiting fermentation and affecting the dough's structure and flavor.
