Corn Starch Vs Baking Soda: A Comparison You Won’T Want To Miss
What To Know
- When heated in the presence of liquid, it absorbs moisture and forms a gel, resulting in a thickened consistency.
- Corn starch is primarily used as a thickening agent, binder, and stabilizer, while baking soda is primarily used as a leavening agent, neutralizing agent, and deodorizer.
- Corn starch excels as a thickening agent, binder, and stabilizer, while baking soda shines as a leavening agent, neutralizing agent, and deodorizer.
In the realm of baking and cooking, corn starch and baking soda are two commonly used ingredients that often spark confusion due to their similar appearance. While both are white powders, their properties, functions, and applications differ significantly. This comprehensive guide delves into the distinct characteristics of corn starch and baking soda, exploring their unique roles in various culinary creations.

Functions and Applications
Corn Starch
- Thickening Agent: Corn starch is primarily used as a thickening agent in various culinary preparations. When heated in the presence of liquid, it absorbs moisture and forms a gel, resulting in a thickened consistency. This property makes it ideal for sauces, gravies, soups, and custards.
- Binding Agent: Corn starch can also act as a binding agent, helping to hold ingredients together. It is often used in gluten-free baking, where it provides structure and texture to baked goods.
- Stabilizer: Corn starch can stabilize emulsions, preventing the separation of ingredients. It is commonly used in salad dressings and mayonnaise to prevent oil and water from separating.
Baking Soda
- Leavening Agent: Baking soda is primarily used as a leavening agent in baking. When combined with an acidic ingredient, such as lemon juice, vinegar, or buttermilk, it releases carbon dioxide gas. This gas creates bubbles in the batter or dough, causing it to rise and become light and fluffy.
- Neutralizing Agent: Baking soda can neutralize acids, making it useful for balancing the flavor of acidic ingredients in recipes. It can also help tenderize meat by breaking down the proteins.
- Deodorizer: Baking soda has deodorizing properties, making it effective in removing odors from refrigerators, carpets, and other household items.
