The Purpose of Baking Soda in Cooking
So, what is the purpose of baking soda in cooking? Baking soda serves several purposes in cooking, including:
Leavening Agent
One of the most common uses of baking soda is as a leavening agent. When baking soda is mixed with an acid (such as buttermilk or yogurt) and a liquid (such as water or milk), it produces carbon dioxide gas. This reaction causes the dough or batter to rise, giving baked goods their light and fluffy texture.
How Baking Soda Works as a Leavening Agent
The process of baking soda working as a leavening agent is quite simple. When baking soda is mixed with an acid, it produces carbon dioxide gas through a chemical reaction. This reaction is known as neutralization. The carbon dioxide gas produced gets trapped in the dough or batter, causing it to rise.
| Ingredients | Reaction | Result |
|---|---|---|
| Baking soda + acid (e.g. buttermilk) | Neutralization reaction | Carbon dioxide gas produced |
| Carbon dioxide gas | Gets trapped in dough or batter | Dough or batter rises |
Neutralizing Acidity
Another purpose of baking soda is to neutralize acidity in recipes. Baking soda can help balance the pH level of a recipe by counteracting the acidity of other ingredients. This is especially useful in recipes that use ingredients like tomatoes, citrus, or vinegar.
How Baking Soda Neutralizes Acidity
Baking soda neutralizes acidity by reacting with the acidic ingredients to produce a neutral compound. This reaction is known as neutralization. The baking soda helps to balance the pH level of the recipe, preventing it from becoming too acidic.
