Sesame flour is a powdered form of ground sesame seeds, often used as a gluten-free, high-protein alternative in baking and cooking. But can it go bad? And how long does it last?
Sesame flour, when stored properly, can last for up to 6-8 months at room temperature. To maximize its longevity, you can keep sesame flour in the refrigerator or freezer for up to 6-12 months.
In this article, I’ll give you the lowdown on sesame flour’s shelf life, signs of spoilage, and the best ways to store it. Let’s get started!
What is the shelf life of sesame flour?
Due to its high fat and protein content, sesame flour doesn’t last as long as regular all-purpose flour.
When stored in a cool, dark, and dry place, unopened sesame flour can typically last for about 6 to 8 months from the date of purchase. Be sure to check the “best by” or “use by” date on the packaging for more specific information.
How long does sesame flour last after opening?
Sesame flour, like many other flours, has a limited shelf life after opening due to its exposure to air and potential for moisture absorption.
After opening, sesame flour stored at room temperature in a cool, dry place and sealed in an airtight container can last for about 3 to 6 months. However, the shelf life can vary based on factors such as humidity and temperature fluctuations.
Storing opened sesame flour in the refrigerator can extend its shelf life. When properly sealed and kept in the fridge, it can remain fresh for about 6 to 12 months.
For even longer storage, you can freeze opened sesame flour. When stored in an airtight container or a freezer bag, it can last for up to a year or more in the freezer.
It’s important to note that these are general guidelines, and the actual shelf life may vary depending on factors like the quality of the flour, storage conditions, and the presence of preservatives.
| Pantry | Fridge | Freezer | |
| Sealed sesame flour | 6-8 months | Not recommended | Not recommended |
| Open sesame flour | 3-6 months | 6-12 months | 12+ months |
Can you use sesame flour after its expiration date?
The expiration date or “use by” date on food products is typically a manufacturer’s recommendation for when the product is at its peak quality and freshness. It doesn’t necessarily mean that the product becomes unsafe to consume immediately after that date.
For many dry goods, including sesame flour, it’s often safe to use the product for some time after the expiration date if it has been stored properly and shows no signs of spoilage (see below).
Remember, while it might not make you sick, using expired sesame flour can negatively impact the flavor and quality of your dishes, so it’s best to use fresh flour whenever possible.
How to tell if sesame flour has gone bad
Spotting spoiled sesame flour isn’t too challenging. Here are some telltale signs:
- Unpleasant odor: Rancid sesame flour has a distinct, unpleasant smell. If it doesn’t smell nutty and fresh, it’s time to discard it.
- Texture changes: If the flour has clumps, become excessively dry, or has an odd, gritty texture, it’s a sign of spoilage.
- Mold: Visible mold growth is a clear indicator that your sesame flour has gone bad. Discard any contaminated flour immediately.
- Off-putting taste: If the sesame flour tastes bitter, sour, or just plain “off,” it’s best not to use it in your recipes.
- Unusual color: Fresh sesame flour should have a consistent color. Any variations or spots that appear discolored could indicate spoilage.
What’s the danger in using sesame flour after it’s gone bad?
Using sesame flour that has gone bad can be risky both for your health and the taste of your recipes.
Spoiled sesame flour may harbor harmful bacteria, molds, or toxins that can lead to foodborne illnesses, resulting in symptoms ranging from mild discomfort to severe illness.
Beyond health concerns, bad sesame flour often develops off-putting odors and flavors, adversely affecting the quality of your dishes, potentially rendering them unappetizing or inedible.
Moreover, as the flour deteriorates, it may lose essential nutrients and develop undesirable textures, diminishing its nutritional value and making it less effective as an ingredient.
Prioritizing food safety and the overall enjoyment of your meals, it’s best to check for signs of spoilage and adhere to expiration dates when using sesame flour.
Best storage practices for sesame flour
Proper storage is the key to extending the shelf life of sesame flour and ensuring its quality.
Here are some tips to keep your sesame flour fresh and tasty:
- Whether you’ve opened the bag or not, transfer your sesame flour to airtight containers to prevent moisture and air from seeping in.
- Store sesame flour in a cool, dry pantry away from direct sunlight and temperature fluctuations.
- If you want to freeze your sesame flour, use freezer-safe bags or containers to protect it from freezer burn.
- Always label your containers with the date of purchase or the date you opened the package. This helps you keep track of freshness.
