How To Store Baking Powder Long Term

Baking powder is an ingredient commonly used in many recipes as a leavening agent. The key to extending the usability of the baking powder is to try to store it from any moisture and air. It is because both of which can affect the potency and function of it as a leavening agent. If you are planning to stock up large quantities, here is the way on how to store baking powder long term:

There are different methods to store baking powder, but the most common step is storing the baking powder in mason jars and use a food sealing system (vacuum) to get rid of the air from the jar. Another method is through vacuum sealing the baking powder in bags.

Baking powder can have an indefinite shelf-life when kept free from moisture and other contamination. But generally, baking powders have shelf-lives that can last for around 18 to 24 months.

Methods To Store Baking Powder Long Term

There are three ways on how to maximize the lifespan of a baking powder:

Storing the baking powder in mason jars and use food sealing system to remove the moisture from the jar

Using a food vacuum system can remove the air from either bags or jars used to store the baking powder and create an airtight seal to lock in the freshness. For your information, moisture is one of the main causes of mold and food spoilage.

With this method, you will need to use mason jars to store baking powder. You will also need a canning jar attachment to seal baking powder in the jar.

Using vacuum systems usually allows your baking powder to last for a year or even longer. Now if the baking powder is stored for over a year untouched, I recommend you to test it, if it is still active or okay to use before using it.

Store the baking powder in mason jars

What you will need:

  • Baking powder
  • Clean and dry mason jars
  • A food saver machine with jar sealing attachment
  • A funnel to be used in placing baking powder over mason jars

Steps to store baking powders in mason jars

  1. Use a deep spoon to ladle baking powder into the jars
  2. Full the jars up just leaving about half-inch space
  3. Place the coffee filter or cupcake liner at the top of the jar
  4. When removing the air from the jar, the food saver may suction some baking powder and then become blocked. The filter or the liner will act as a barrier between the baking powder and the machine.
  5. Soak the jar lids in boiling water, then wipe the jar lids until they become completely dry.
  6. Remove any residues of the baking powder by wiping the around the ring lid of the jar.
  7. To use the food saver with the canning jar attachment, place the flat lid on top of the jar, you will not need the ring to hold the lid on.
  8. Set the canning jar vacuum seal attachment on top, connect it to the hose attachment, and then press the “Start” button on the vacuum sealer appliance. (The hose attachment will come with the Food Saver unit.)
  9. The canister attachment will vacuum out the air from the jar. Then place the ring around the lid of the mason jar.

Vacuum Seal The Baking Powder In Bags

The baking powder can be vacuum-sealed in bags so that it will last longer. However, vacuum sealing baking powders can be a bit tricky, so it is important to follow the guide to avoid any damage to your vacuum sealing system.

Since the particles of the baking powder are so small, they may be sucked into the vacuum system and damage the food saver system.

I would recommend placing the baking powder in another zipper bag, pricking the top with a safety pin before putting the zipper bag into the vacuum bag. The zipper bag will act as a barrier to stop the powder from being sucked into the system.

Steps to vacuum seal baking powder in bags

  1. Remove the baking powder from the original packaging and place it in the food-safe zipper bag
  2. Try to remove as much air before sealing the zipper bag
  3. With the use of a safety pin, prick numerous tiny holes just below the zipper. This allows the air to be removed by the food system, but not the baking powder.
  4. Place the zipper bag upside down in the vacuum bags. The side with the zipper that has holes should be at the bottom.
  5. When turning the zipper bag upside down, some baking powder will escape from the tiny holes and fall into the bottom of the vacuum bag.
  6. Don’t be afraid, this is normal and since it is the bottom, most likely it will not get sucked up into the system.
  7. Put the unsealed on top of the vacuum bag to connect it to the system and start the machine.
  8. The machine will then remove any excess air from the bag without suctioning the baking powder.
  9. Write the date and the contents of the bag.

How To Store Baking Powder After Opening

The key to storing baking powder is to keep it away from moisture and place them in a clean and dry airtight container in the dark area of your home.

Once you open the package of baking powder, make sure to keep it tightly sealed. You may follow any of the methods mentioned above. If you are not planning to use it, it is best to transfer it to an airtight container and keep it in a dark cupboard or the pantry.

Can You Store The Baking Powder In The Fridge?

Baking powder should be stored in a dry cupboard away from heat and excessive moisture. You must use a dry utensil in measuring it and replace the lid every after use. If you use a utensil that is damp, it can cause a reaction inside the can and teh baking powder may not be working properly.

Meanwhile, you should never, ever try to refrigerate or freeze the baking powder. While putting things in the fridge can extend the shelf-life, the opposite is true for baking powder. Putting the baking powder in the fridge or freezer can end up ruining the powder, making it unusable for baking.

This happens because the condensation from the fridge can cause the baking powder to activate inside the can. When this happens, it is not possible to return the baking powder to its original state, rendering it useless for cooking and baking.

A similar event will happen if you choose to place the baking powder in the freezer.

The freezer’s harsh environment can damage the baking powder, meaning you will not be able to use it for cooking anymore.

Just like putting it in the fridge, placing the baking powder in the freezer will put it in an irreversible state, meaning you will not be able to fix it or bring it back to its original state. This is worthy to note if you want to make sure that you will not end up wasting your baking powder.

How Long Can Baking Powder Be Stored

Unopened baking powder can be stored for up to 18 months and still be fresh and usable. After that, you will likely notice a loss in potency when using it in baking some recipes.

Opened baking powder should be used within 6 months to avoid contamination. Many packages include the place where you can write the date you opened the lid, this is a helpful way to track the freshness of the product.

Baking soda and powder are both important ingredients in baking and to assure they are effective, freshness must always be monitored.

How To Test The Baking Powder For Freshness

Just like with many baking ingredients, baking powder can go bad. While you may not think about it going bad or become unusable, baking powder is unique because it will not be nearly as effective if it is no longer fresh.

Often you can use the can’s expiration or best-by-date as a guide to how old your baking powder is. If you cannot find the date, you might feel lost on how you can check if the baking powder is still good. Thankfully, there is a method that you can use to test the freshness.


  1. Get a quarter-cup of water, then mix about half a teaspoon of baking powder into the cup. You can stir it in to ensure that it is thoroughly mixed.
  2. If the mixture bubbles, the baking powder is still fresh after you stir it a bit. If it does not react with water, it is now time to replace the baking powder.

Once the baking powder goes bad, it will not be dangerous to your health, so you don’t have to worry about accidental ingestion.

However, expired baking powder will not be nearly as effective as helping the baked goods rise when they are in the oven. This means that the goods will turn out flat and with the wrong texture.
