Leavened bread is bread that contains leavening, usually yeast. Leavened bread is soft, light, and fluffy in texture. It contains tiny air pockets, making it somewhat resemble a sponge. The leavening which was mixed into the bread dough causes the dough to rise both before it is baked and during baking.Examples are most kinds of bread you would buy in a grocery or bakery-French bread, Italian bread, sandwich breads and rolls, muffins, etc.east, baking powder, and a combination of baking soda â¦ and vinegar or lemon juice, are the typical leavening agents used in baking. Leavened bread is bread that incorporates any, some, or all of the above agents.
Bread made from 100 percent rye flour, which is very popular in the northern half of Europe, is usually leavened with sourdough. Baker's yeast is not useful as a leavening agent for rye bread, as rye does not contain enough gluten.btaining a satisfactory rise from sourdough takes longer than a dough leavened with baker's yeast because the yeast in a sourdough is less vigorous. In the presence of lactic acid bacteria, however, some sourdough yeasts have been observed to produce twice the gas of baker's yeast.
