carbon dioxide
Bread rises due to the action of yeast, which consumes sugars and produces carbon dioxide gas. The gas gets trapped in the dough, causing it to inflate and rise. This process is called fermentation and is what gives bread its airy texture.
Bread rises in the oven due to the process of fermentation and the release of carbon dioxide gas by yeast. The yeast consumes sugars in the dough and produces carbon dioxide, which gets trapped in the gluten structure of the dough, causing it to expand and rise.
The fermentation (growth of microorganisms as they digest sugar) in any yeast dough is obvious when the dough rises. If the dough does not rise, you know that fermentation has not taken place.
When bread rises, it is a sign that yeast, a type of fungus, is producing carbon dioxide gas through fermentation. The carbon dioxide gas gets trapped within the dough, causing it to rise and create a light, airy texture in the bread.
Bulk fermentation is a process in bread making. During the process of bulk fermentation the dough prepared for the bread is left in a warm temperature, due to which the bacteria in the yeast multiply and the dough rises to double.
The yeast cells in bread dough ferment sugars and produce gas (carbon dioxide). This makes the dough rise.
Because it is. as you know bread is yeast therefore yeast rises to the top and expands leaving the bread bigger than it was. Source: www.eatmypooanddrinkmypee.co.uk
The protein molecule in bread that traps carbon dioxide to help the bread rise is called gluten. Gluten forms a network when mixed with water, which traps the carbon dioxide released by yeast during fermentation. This trapped gas causes the bread to rise and gives it a light and airy texture.
Gluten.
The answer is yes. This is because a few minutes after the bread rises the volume increases, density decreases.
Carbon dioxide
its bcuz air is enterning the bread..!! then it makes the bread rise and air bubbles or aka holes
