How to Tell If Sesame Seeds Are Bad?

So, here’s how to determine whether or not opened sesame seeds in a bag that you’ve had for a very long time in your pantry have gone rancid.

Aroma: Sesame seeds often have a nutty, fresh scent. If the scent has become sour and off, you should head to the food store right away. Sesame seeds that have gone bad not only taste bad but are bad for your health as well. In other words, if your nose says “no,” it’s a no!

Flavor: Another effective method for determining if something is safe to consume is your sense of taste. Sesame seeds often have a nutty, fresh flavor. But if the flavor has changed and is now foul, you must discard the seeds. Who would want to ruin their cuisine with such disgusting toppings, right?

Molds: Molds enjoy food just as much as we do. So keep an eye out for this adversary. Sesame seeds don’t frequently contain molds. But if your seeds have come into contact with moisture, there is a good probability that mold will develop. Mold may be present if you see a white, gray, or black fuzzy matter inside the package or container of sesame seeds.

How To Store Sesame Seeds?

You now understand when to discard sesame seeds. However, are you aware of the best ways to keep them so you won’t have to throw them away before using them? We do, after all! We’ll also provide you with great sesame storage advice.

Airtight Container

Sesame seeds should, of course, always be kept in airtight containers with the lids on. Consider putting them in a plastic bag to keep them cool if you live in a hot region. Make sure to remove all of the air from a plastic bag before closing it if you’re keeping them. A kitchen cryovac machine can be used for this. This is the ideal course of action if you want to keep the seeds fresh for a long time!

Sesame seeds are known to support mold development and become rancid when exposed to air, which brings moisture into the seeds.

Cool and Dry Place

Sesame seeds should also be kept in a cool, dry location away from heat and sunshine. Rancidity is known to accelerate in the presence of heat and sunshine. Sesame seeds should, if at all possible, be maintained at a steady temperature because sharp temperature changes are bad for their quality.

Freeze or Refrigerate

In case you didn’t know, cooling and freezing seeds extend their shelf life by preventing rancidity. Additionally, seeds are kept at a consistent temperature in freezers or refrigerators.

Simply place the seeds in a freezer or refrigerator in an airtight container. Squeeze as much air as you can out of freezer bags if using them.


Sesame seeds have a far longer shelf life than tahini. Therefore, making all of your sesame seeds into tahini at once might not be a smart idea if you bought them in bulk. Consider preparing tahini in bulk if you enjoy it and use it frequently.

In the refrigerator and freezer, tahini keeps for between 6 and 12 months and for around 4-6 months in the pantry. The taste of tahini improves with freshness, so you may start by creating a quantity that will survive for the first two to three months.

What Happens If You Consume Expired Sesame Seeds?

Consuming sesame seeds over their expiration date won’t likely make you sick because it is the date by which they are most likely to retain their quality and flavor. But the situation could not be the same if you eat moldy or rotten seeds.

However, there won’t likely be any detrimental effects if you eat a handful of rancid sesame seeds or even fewer. Nevertheless, it is certainly not a good idea to consistently consume rancid sesame seeds while being aware that they have gone bad.

In conclusion, you’ll probably be alright if you accidentally add a pinch or two of outdated sesame seeds to your dish. On the other hand, consuming too much of it may provide a number of health hazards.
