Carbon dioxide
Carbon dioxide
answer 2 In the fermentation process, the yeast produces CO2 which, as bubbles, makes the bread more porous, and 'rise'.
Fermented bread contains yeast. During anaerobic respiration, the yeast produces CO2 as a byproduct of fermentation; the CO2 makes the bread rise. Without yeast, there is no fermentation- no CO2 is produced, and the bread does not rise.
Fermentation - creates bubbles of carbon dioxide... which causes the dough to rise, and gives bread light, open texture.
Yeast makes the bread rise. This happens due to alcoholic fermentation. This is so that the yeast can reproduce. :)
Alcoholic fermentation. Bread dough which has risen contains (a very small amount of) ethanol in addition to the carbon dioxide which is what actually makes it "rise". Most of the ethanol cooks out during the baking process.
Fermentation causes bread dough to rise. Certain yeasts and bacteria are capable of producing energy from sugars through fermentation. Yeast such as S. cerevisiae causes bread dough to rise. - Intro to Biotechnology (Third Edition): Thieman & Palladino
Pan de sal is a kind of bread, meaning that the yeast causes it to rise like it causes any bread to rise. Namely, yeast causes fermentation, and in breads, this interaction with the monosaccharides found in the dough creates carbon dioxide bubbles that cause the bread to rise.
During alcoholic fermentation, yeast consumes sugars in the dough and produces carbon dioxide gas as a byproduct. The carbon dioxide gas gets trapped in the dough, causing it to rise and create air pockets or bubbles, resulting in a lighter and fluffier texture of the bread.
Alcoholic fermentation
Bread. Without it, the bread would never rise.
alcohol fermentation -- the ethanol (alcohol) and carbon dioxide are produced by the yeast.
