After reactivation, yeast begins to eat flour sugar and releases carbon dioxide that raises the bread (although much slower than baking powder or soda)
What process causes bread to rise what gas is being released?
Yeast releases enzymes to make flour starch. Is converted to sugar, which is absorbed and metabolized by cells. This process releases CO2 gas, forming bubbles and trapping them in a stretchy fabric. During baking, the heat from the oven causes the foam to expand further.
The basic motivational gases commonly found in baking recipes are Water vapor or vapor; carbon dioxide; and biological. In baking recipes, one or more leavening agents are involved in the selling process.
