Baking soda and baking powder are among the most often used chemical leavens. Chemical leavening agents react immediately when combined with a liquid; therefore, they are mixed with the other dry ingredients before any liquid ingredients are added. Chemical leavening agents allow bread dough to be prepared in minutes instead of hours.
The chemical leavening agent, baking powder, is a mixture of baking soda, an alkaline ingredient; cream of tartar, an acidic ingredient; and a starch, such as cornstarch, which prevents clumping of the powder.
It is most often used in quick bread recipes that contain no acidic ingredients. It reacts immediately when added to liquids. The first reaction occurs when the baking powder is mixed with liquid ingredients causing carbon dioxide gas to be produced, which causes the batter or dough to rise.
The second reaction occurs when heat is applied during the baking process, which causes further expansion. Baking soda is an alkaline leavening agent made of sodium bicarbonate that reacts immediately when combined with a liquid.
In most quick bread recipes, the baking soda is mixed with the other dry ingredients before any liquid ingredients are added. In order for baking soda to work properly as a leavening agent, it must be used in recipes that contain acidic ingredients, such as molasses, buttermilk, or chocolate. The chemical reaction produces carbon dioxide gas, which cause the batter or dough to rise.
Cream of tartar is also used as a leaven. It is an acidic ingredient that is often used in conjunction with baking soda, which is an alkaline ingredient. Chemical Leavening Agents Reviews. By cooking the dough once on the stovetop, the glutens are partially denatured, which reduces the dough's elasticity. Meanwhile, the starch in the flour is gelatinized, which helps give it structure.
Thus when it's baked, the steam inflates the pastry but rather than snapping back, it holds its shape and the air pockets in the center of the pastry remain intact.

Like baking soda, it makes products rise by producing carbon dioxide gas; however, it does so in two phases. This two phase rising method is known as double-acting. There are single-acting baking powders available; these powders only rise once during the heating stage of baking.
Your recipe will specifically call for single-acting baking powder if needed. Most baking powders are commonly double-acting. Put one teaspoon of baking powder in a small bowl and mix in one tablespoon of warm water. You can make your own. So, what is it? After wine has been fermented and aged in barrels, it leaves behind a powdery substance.
That substance is harvested and purified and sold as cream of tartar. All of these products should be stored in their original containers in a cool, dry place - not over your stove. The heat and moisture from cooking could chemically alter them.
