Composition of Baking Powder
Baking powder is a leavening agent used in baking.
It typically consists of three main components:
- An acid: This can be cream of tartar or a similar compound.
- A base: Usually, this is sodium bicarbonate (baking soda).
- A filler: This is commonly cornstarch, which absorbs moisture and prevents premature reactions.
The combination of these ingredients allows baking powder to release carbon dioxide gas when mixed with moisture and exposed to heat.
This gas forms bubbles in the batter or dough, causing it to rise.
There are two primary types of baking powder:
- Single-acting: This type reacts with moisture to produce gas immediately. It needs to be baked right after mixing.
- Double-acting: This type releases gas in two phases—once when mixed with liquid and again when heated. This provides more flexibility in baking time.
Baking powder should be stored in a cool, dry place to maintain its effectiveness.
Expired baking powder loses its leavening ability, so checking freshness is essential before use.
