Does Almond Flour Go Bad?

Yes, it does. Almond flour is made from ground almonds, which means that it is high in oil, and this oil will turn rancid over time.

If you won’t be able to use up your nut flour within a few months, store it in an airtight container and then put it in the refrigerator or freezer to prevent spoilage.

You should also stop buying it in bulk to avoid having large amounts of unused flour lying around on your pantry shelves.

What Is the Shelf Life Of Almond Flour?

The shelf life of almond flour depends on whether or not you open it and how you store it.


Unopened almond flour has a shelf life of about 2-4 months past its best-by date at room temperature. It will keep for about 6-12 months past its best-by date in the refrigerator, and about 1-2 years past its best-by date in the freezer.


Opened almond flour will last until its best-by date when stored in an airtight container at room temperature. To increase its shelf life, put it in the refrigerator where it will last for 3-6 months or in the freezer where it will last for 6-12 months.

Can Expired Almond Flour Make You Sick?

The answer is yes. Expired almond flour can make you sick because it usually contains high levels of aflatoxins- a family of toxins that occurs naturally in spoiled foods.

The FDA has found that aflatoxins can cause liver damage and even death if consumed regularly by people with weakened immune systems or those who have chronic liver disease.

Your expired nut flour can also get contaminated with bacteria over time, consequently causing illness when you or someone else consumes it.

How to Tell if Almond Flour Is Bad

Check its expiration date

The easiest way to determine if your flour is bad is by checking its expiration date. The longer the product has been sitting on your shelf past its expiration date, the more likely it is to have gone bad.

Smell it

If your nut flour smells like almonds, then it’s good to go. But if the flour smells sour, rancid, or off in any way, throw it out immediately. This indicates that bacteria have grown inside the container and begun producing hydrogen sulfide gas, which smells like rotten eggs.

Look at the color of the flour

It should be a light brown color, not a dark brown or greenish color. If your nut flour is dark brown or greenish, toss it out immediately.

Look for mold

Mold can grow on top of your flour if you don’t keep it properly. If you notice any mold growth on your flour, throw it away immediately and wash your hands to prevent food poisoning.

Do a taste test

If you taste your flour and find that it tastes bitter or unpleasant (unlike almonds), then toss it out immediately. This means that there are microorganisms present in the product that is spoiling its flavor profile.

How to Preserve Almond Flour

Keep it away from heat sources

You should avoid exposing your nut flour to heat at all costs. Heat speeds up the oxidation process which can cause rancidity and spoilage over time.

Instead, place the flour in an airtight container and store it in a cool dry place until you’re ready to use it again. This helps prevent mold and bacteria from growing in the flour over time.


Another great way to preserve your flour is to put it in the refrigerator. Just make sure to use an airtight container before storing it in the fridge. This will help keep out any moisture or bacteria that could damage your nut flour over time.


You can freeze your flour safely if you use an airtight, freezer-safe container. Just be sure to keep it away from other items with strong odors that may contaminate it. To use the frozen flour again, just thaw it in a refrigerator or at room temperature.
