As a curious observer, have you ever wondered why other people put baking soda in their refrigerators and leave it there for a long time? For some people, it’s common practice to keep an open box of baking soda in the fridge for a long period of time. Baking soda is mostly used to counteract the stench of food stored in the refrigerator.

Using baking soda to neutralize the foul stench is a great way to keep your fridge smelling fresh. Your fridge will no longer smell like baking soda after it absorbs the odor, indicating that baking soda can swiftly remedy your stinky fridge problem.

Many people are bothered by and avoid situations in which foul odors are present. One of the reasons for an unpleasant refrigerator odor is the accumulation of food particles and moisture in the refrigerator’s vegetable bin. In this article, we’ll explain the benefits of storing baking soda in the refrigerator to combat foul odors.

Reasons Why You Put Baking Soda In The Fridge

You may be wondering why so many people keep a bowl of baking soda in their refrigerator. Other items in the refrigerator may also emit an unpleasant odor without the presence of baking soda.

Does Putting Baking Soda in Your Fridge Really Kill Odors?

You may have inferred that the baking soda is responsible for keeping the fridge odor-free when all the elements are put together. Here are five reasons why you should have baking soda in your fridge.

Reason #1. To minimize the odor

Baking soda, as the wise ones have always stated, is effective in reducing fridge odors. Having a smelly fridge is something that no one wants. Adding baking soda to the mix is a great approach to get rid of the odor.

The food’s small particles emit an unpleasant odor as they decompose. Other food products will be harmed if these tiny particles land on them. This necessitates using baking soda to keep the other ingredients safe.

Reason #2. To keep the quality of the products

In addition to reducing fridge odors, baking soda also helps preserve the quality of other products. For example, if you put fresh fruits and vegetables in a bin underneath a refrigerator that has onions in it, the new products would eventually develop an onion fragrance.

As a result of the molecules from the onion settling on these products, nothing can neutralize them. In order to maintain the freshness of food in the refrigerator, baking soda is also required.

Reason #3. To absorb the molecules

The smell of rotting food in your refrigerator is the most prevalent culprit. It doesn’t matter how often you clean your fridge or get rid of the rotting food; the smell will return. Baking soda not only reduces the scent, but completely neutralizes it as well.

Baking soda is a frequent ingredient in refrigerators because it absorbs the odor-causing chemicals. To neutralize the food’s acidic and alkaline solid components, baking soda, or sodium bicarbonate, is used.

The sodium bicarbonate neutralizes the food particles as soon as they come into contact with it, preventing them from emitting a disagreeable odor.

Reason #4. Scientific reason

Baking soda does, in fact, eliminate refrigerator odors for a scientific reason. Baking soda is a weak base that neutralizes acid and solid alkaline molecules, as we discussed in the second reason. If the sodium bicarbonate absorbs a certain particle, it will either function as an acid or a base, and this is an important fact to keep in mind.

Acidic or basic molecules can be produced by the food in your fridge. The sodium bicarbonate will neutralize the odors caused by the molecules floating around in your fridge. Sodium bicarbonate is composed of tiny crystals, with each one providing a space for the molecule it will absorb. This should be kept in mind when using this product! A modest bit of baking soda would not be enough to remove all the aromas from the fridge if you simply used a small amount.

Does Baking Soda Go Bad?

The efficacy of baking soda can degrade with time, even if it is stored after the expiration date on the package. Unopened packages can be stored for two years, but opened packages can be stored for up to six months. Even while it may not have as much leavening effect as new baking soda, aged baking soda is still safe to consume. Even if your recipes don’t turn out perfectly, you can still enjoy the food you make.

Baking soda, unlike baking powder, requires an acid to be activated. No matter how much moisture it picks up from the air, it won’t start the bubbling process. So, instead of a sealed container like with baking powder, baking soda is sold in cardboard canisters that open with a loose flap. It’s not uncommon for the packaging of baking soda to be without an expiration date.

If your baking soda has been exposed to acidic moisture, it may be ineffective. The vinegar, lemon juice, or other acid-containing water may have gotten on it while it was on the counter. Your water may be slightly acidic, or it may have picked up acidic residues from your counters, so check that. In most cases, you’ll observe that the box has gotten moist and the bubbling motion has taken place.

Baking powder, on the other hand, contains the acid in the powder itself. It’s inevitable that the chemicals may degrade with time, especially if you’ve opened the container and let air and moisture in. Keeping track of its expiration date would be necessary. It’s a good idea to include the date you opened the baking powder on the label.

How to Test If It Is Still Potent

You’ll need acid, like as vinegar, to check if your baking soda is spoiled before using it. Adding baking soda to your recipes produces carbon dioxide gas by reacting with the acidic ingredients. The gas bubbles in the dough are what cause it to rise. In addition to producing carbon dioxide gas, yeast and baking powder also aid in the dough’s rise.

  • Pour some baking soda into a container.
  • Boost the acidity with a few drops of vinegar, lemon juice, or any acidic beverage.
  • It doesn’t matter if the mixture fizzes a lot; baking soda is fine.
  • Baking soda is terrible if you don’t get much of a fizz.
  • Buy another box for baking and use the rest of the box for cleaning.

How to Store Baking Soda in the Pantry

Assuming you’re reading this blog, I’m going to assume that you’re like me and often use your baking soda and then toss it back into the pantry. The only thing you didn’t do was keep it in the standard cardboard box.

Is it possible that I’m telling the truth? The lack of an airtight seal makes it difficult to store baking soda in the cardboard box. Because it’s absorbing the scents in the air, your baking soda is degrading faster than you may expect.

In order to get the most out of your baking soda, you may want to try this instead:

  1. Open the fresh baking soda box and use it for what it was intended for.
  2. Keep it in an airtight jar for future use.
  3. Use a spoon or scooper to remove the baking soda when you’re ready to use it again.

Baking soda really is that simple to keep in the pantry. Freshness can be preserved for many years in an airtight container.

Which Containers Are Best?
