Cassava flour is a versatile and gluten-free alternative to traditional wheat flour, but like any other ingredient, it’s not immune to going bad.
In a nutshell: Cassava flour typically has a shelf life of two years when stored properly, but it can last even longer. Once opened, it should be used within a year for optimal quality.
In this article, I’ll explore the factors that influence the longevity of cassava flour, storage tips to extend its freshness, and how to tell if your cassava flour has gone bad. So, let’s dive in!
What is the shelf life of cassava flour?
Generally, cassava flour has a relatively long shelf life, especially when stored correctly in a cool, dry, and airtight container.
If you have an unopened package of commercially packaged cassava flour, it can last for up to 2 years or even longer if stored in optimal conditions. This is similar to coconut flour.
Check the expiration date on the packaging for more specific information.
How long does cassava flour last after opening?
Once you open a package of cassava flour, it can still last for 1-2 years, depending on storage conditions.
When stored in an airtight container in a cool, dry, place such as a pantry, cassava flour can last around 1 year. You can extend this a little further by keeping it in the refrigerator.
For even longer storage, you can freeze cassava flour for up to 2 years without significant loss of quality.
It’s important to note that while cassava flour has a relatively long shelf life, the quality may deteriorate over time, and it may not perform as well in recipes the older it gets. To ensure the best results in your cooking and baking, try to use it within a reasonable timeframe and store it properly.

Pro Tip: For the longest shelf life, consider vacuum-sealing your cassava flour after opening, especially if you plan to store it in the fridge or freezer.
Can you use cassava flour after its expiration date?
While cassava flour has a long shelf life, it’s important to pay attention to the expiration date on the packaging. The date provides a general guideline for when the flour is at its freshest and most reliable. However, it doesn’t mean the flour instantly turns bad after that date.
Cassava flour, like many dry goods, can still be safe to use for some time after the expiration date, as long as it has been stored properly. Before using expired cassava flour, perform a sensory check (which we’ll discuss in detail shortly) to ensure it’s still suitable for your recipes. If the flour exhibits any off-putting smells, discoloration, or an unusual texture, it’s best to discard it to avoid any potential health risks.
How to tell if cassava flour has gone bad
Here are some telltale signs that your cassava flour has gone bad:
- Odor: Fresh cassava flour should have a neutral, slightly nutty aroma. If it smells rancid, sour, or off in any way, it’s a sign that it may have gone bad.
- Color: Cassava flour is typically bright white. Any noticeable discoloration, such as yellowing or the presence of dark spots, can indicate spoilage.
- Texture: The texture of cassava flour should remain fine and powdery. If it feels clumpy, gritty, or has an unusual consistency, it’s a clear sign of degradation.
- Taste: If you’re in doubt, taste a small amount of the flour. Spoiled cassava flour may have a bitter or off taste that is distinct from its usual mild flavor.
Remember, it’s always better to err on the side of caution. If you notice any of these signs, it’s best to discard the cassava flour and get a fresh batch to ensure your recipes turn out as expected.
What’s the danger in using cassava flour after it’s gone bad?
Using cassava flour that has gone bad can pose health risks. When flour deteriorates, it can become a breeding ground for harmful microorganisms, such as bacteria and molds.
Consuming contaminated cassava flour can lead to foodborne illnesses, which can cause symptoms like nausea, vomiting, diarrhea, and abdominal pain.
Furthermore, cassava contains naturally occurring compounds called cyanogenic glycosides, which can release cyanide when ingested in large amounts. While properly processed cassava flour contains minimal cyanide, the breakdown of cassava flour due to spoilage may release more cyanide than is safe for consumption. Therefore, it’s crucial to avoid using cassava flour that shows signs of spoilage!
Best storage practices for cassava flour
To ensure your cassava flour stays fresh for as long as possible, here are some best practices for storage:
- Whether it’s an unopened bag or an opened container, always seal cassava flour tightly to prevent air and moisture from compromising its quality.
- Moisture is the enemy of cassava flour. Store it in a dry environment, and if you live in a humid climate, consider using moisture-absorbing packets in the storage container.
- Keep cassava flour away from direct sunlight and sources of heat, such as stovetops and ovens, which can cause it to deteriorate more quickly.
- If you transfer cassava flour to a different container, make sure it’s airtight. This prevents exposure to air, which can lead to faster spoilage.
- If you’re storing cassava flour in containers, label them with the contents and date of storage. This helps you keep track of freshness.
- If you don’t plan to use cassava flour frequently, consider keeping it in the fridge or freezer for extended shelf life.
Cassava flour typically comes with a “best by” or “use by” date on the packaging. This date provides a general guideline for its freshness. To determine if cassava flour is expired, check for signs such as off smells, unusual colors, textures, or tastes. If any of these indicators are present, it’s best to discard the flour.
Unopened cassava flour can have a shelf life of up to two years when stored in a cool, dry place. However, the actual shelf life can vary depending on factors like packaging quality and storage conditions. It’s essential to perform sensory checks to ensure its quality before using.
Cassava flour can last about a year after opening when stored in a pantry, longer when refrigerated, and up to 2 years when frozen.
