Key Facts

Baking soda, or sodium bicarbonate, is a leavening agent that reacts with acidic ingredients to produce carbon dioxide, causing dough to rise.

Fridge and freezer baking soda is formulated to absorb odors and may contain larger granules, making it less effective for baking.

Baking soda stored in the fridge can absorb odors and moisture, which can affect its potency and the flavor of baked goods.

Arm & Hammer, a leading baking soda brand, recommends replacing fridge and freezer baking soda every 30 days for optimal odor absorption.

Baking soda has an indefinite shelf life but can lose its potency over time; testing it with vinegar can determine its effectiveness for baking.

Can You Use Fridge and Freezer Baking Soda for Baking?

While fridge and freezer baking soda is chemically identical to regular baking soda (both are sodium bicarbonate), it’s not ideal for baking. This type of baking soda is specifically designed to absorb odors in your refrigerator or freezer, meaning it has likely taken on the smells and flavors of the surrounding food. Using it in your baking could impart these undesirable flavors to your final product, resulting in off-tasting cookies, cakes, or bread.

Baking is a precise science, and using the right ingredients is crucial for achieving the desired texture and flavor. When a recipe calls for baking soda, it’s referring to the pure, unadulterated form that hasn’t been exposed to the various aromas in a refrigerator or freezer. Fridge and freezer baking soda, while useful for its intended purpose, is not formulated to meet the specific requirements of baking, where purity and potency are paramount.

Furthermore, the granulation of fridge and freezer baking soda may differ from that of regular baking soda. Some sources, like Arm & Hammer, state that their fridge and freezer product has a granulation designed specifically for deodorizing, which might not be as fine as the baking soda intended for culinary use. This difference in texture can affect how the baking soda dissolves and reacts with other ingredients, potentially leading to an uneven rise or an undesirable texture in your baked goods.

Why is Baking Soda Used in the Fridge and Freezer?

Baking soda is a powerhouse when it comes to odor absorption. Its chemical structure allows it to react with both acidic and basic odor molecules, effectively neutralizing them. This is why it’s commonly used to keep refrigerators and freezers smelling fresh.

Odor Neutralization: Baking soda, or sodium bicarbonate, is amphoteric, meaning it can react with both acids and bases. Many food odors are acidic, and baking soda neutralizes them, reducing their smell.
Moisture Absorption: Baking soda can also absorb moisture, which helps prevent the growth of mold and mildew, further contributing to a fresher-smelling fridge.
Porous Structure: The granular structure of baking soda provides a large surface area for odors to be absorbed.

What Happens When Baking Soda is Used for Deodorizing?

When baking soda is placed in a fridge or freezer, it starts to absorb the volatile organic compounds (VOCs) that cause odors. Over time, the baking soda becomes saturated with these compounds, which is why it needs to be replaced regularly.

Saturation: As baking soda absorbs odors, it gradually loses its effectiveness.
Flavor Transfer: The absorbed odors can potentially be transferred to food if the baking soda is reused.
Chemical Alteration: While the chemical composition of baking soda (sodium bicarbonate) remains the same, its ability to react with other substances might be affected after prolonged exposure to fridge odors.

Are There Any Health Risks Associated with Using Fridge and Freezer Baking Soda in Baking?

Consuming fridge and freezer baking soda that has absorbed odors is unlikely to pose significant health risks, as baking soda itself is non-toxic. However, the potential for unpleasant flavors in your food is a real concern.

Non-Toxic Nature: Sodium bicarbonate is generally recognized as safe for consumption.
Unpleasant Taste: The primary risk is the transfer of absorbed odors to your baked goods, leading to an undesirable taste.
Reduced Effectiveness: Baking soda that has been used for deodorizing may be less effective as a leavening agent.

How Does the Granulation of Fridge and Freezer Baking Soda Affect Baking?

The texture of baking soda plays a role in how it reacts with other ingredients. Fridge and freezer baking soda might have a coarser granulation, which could affect its ability to dissolve evenly and react fully in a recipe.

Dissolution Rate: Finer granules dissolve more quickly and evenly, ensuring a consistent reaction with acidic ingredients.
Texture Impact: Coarser granules might not fully dissolve, leading to a gritty texture in the final product.
Leavening Efficiency: Uneven dissolution can result in an inconsistent rise, affecting the texture of baked goods.

What is the Difference Between Baking Soda and Baking Powder?

Baking soda and baking powder are both leavening agents, but they work differently. Baking soda requires an acidic ingredient to activate it, while baking powder contains both a base (sodium bicarbonate) and an acid.

Baking Soda: Pure sodium bicarbonate; needs an acid to react and produce carbon dioxide.
Baking Powder: Contains sodium bicarbonate, an acid (like cream of tartar), and a drying agent (like cornstarch).
Usage: Baking soda is used in recipes with acidic ingredients (e.g., buttermilk, vinegar), while baking powder is used when no additional acid is present.

How to Test Baking Soda for Potency?

To ensure your baking soda is still active, you can perform a simple test. Add a teaspoon of baking soda to a small amount of vinegar. If it fizzes vigorously, it’s still good to use.

Vinegar Test: A strong fizz indicates the baking soda is still potent.
Water Test: You can also test with hot water; a slight fizz should be visible.
Visual Inspection: Fresh baking soda should be a fine, white powder without clumps.

Can You Use Expired Baking Soda for Baking?

Baking soda has an indefinite shelf life, but it can lose its potency over time. Using expired baking soda might result in baked goods that don’t rise properly.

Shelf Life: While baking soda doesn’t technically expire, its effectiveness can diminish after about 6-12 months.
Storage: Proper storage in a cool, dry place can help extend its shelf life.
Effectiveness Test: Always test expired baking soda for potency before using it in baking.

How Should Baking Soda Be Stored for Baking?

Proper storage is key to maintaining the potency of baking soda. Keep it in an airtight container in a cool, dry place, away from strong odors.

Airtight Container: Prevents moisture and odor absorption.
Cool, Dry Place: A pantry shelf is ideal.
Separate from Odors: Store away from spices and other strong-smelling items.

What Are the Best Alternatives to Baking Soda in Baking?

If you’re out of baking soda, there are a few substitutes you can use, though they may slightly alter the texture or flavor of your baked goods.

Baking Powder: Use 1 teaspoon of baking powder for every 1/3 teaspoon of baking soda.
Potassium Bicarbonate: A 1:1 substitution, but it may result in a slightly saltier taste.
Self-Rising Flour: This already contains baking powder and salt, so adjust your recipe accordingly.

Can You Use Fridge and Freezer Baking Soda for Cleaning?

Absolutely! Even if it’s not suitable for baking anymore, fridge and freezer baking soda can still be used for various cleaning tasks around the house.

Scouring Agent: Its mild abrasiveness makes it great for scrubbing sinks, tubs, and countertops.
Deodorizer: Sprinkle it in trash cans, carpets, or shoes to absorb odors.
Laundry Booster: Add a 1/2 cup to your laundry to help brighten whites and remove odors.
