How Long Do Sesame Seeds Last?

Do sesame seeds go bad? How long does tahini last? The shelf life of sesame seeds depends upon a variety of factors, such as the Best By Date, whether they are roasted or salted and how they are stored. Sesame seeds are rich in calcium, iron and saturated fat [1]. They are most often seen sprinkled on top of breads or bagels or ground into creamy butter called tahini. They can be eaten raw, but are usually roasted to eliminate the bitter flavor. The shelf life of tahini and sesame seeds is so long that many ask do sesame seeds goes bad, does tahini go bad?

When properly stored, the shelf life of sesame seeds is approximately…

Opened/Unopened Pantry Fridge/Freezer
Past Printed Date Past Printed Date
Sesame Seeds (Raw) last 6-12 Months 1 Year
Roasted Sesame Seeds last 1-3 Years 1-3 Years
Tahini lasts 4-6 Months 6-12 Months
Tahini Paste lasts 4-6 Months 6-12 Months




Of course, sesame seeds and tahini last for a shorter period of time if they are not stored properly. But remember, sesame seeds, like a lot of other seeds, usually have a best by date and not an expiration date. Because of this, you can safely use them beyond their best by date.

How to tell if sesame seeds are bad, rotten or spoiled?

Since sesame seeds have a long shelf life if kept dry, it is hard to tell if they have gone bad. The best way is by smell – they will start to smell rancid because of the natural oils breaking down. Once they start to smell they also taste pretty nasty.
When tahini goes bad, it is also given away by the rancid odor that develops. Tahini will naturally separate and become oily on top, this oil should be mixed back in before use (or you can turn the jar upside down for a few days).
There are of course certain health risks associated with spoiled foods, so always remember to practice food safety and enjoy them prior to their expiration.

How to store sesame seeds to extend their shelf life?

Proper food storage is the key to extending the expiration date of food. The best way to store sesame seeds is in an airtight container or bag in the pantry or another cool dark place with a constant temperature.
Tahini should be refrigerated in an airtight container after opening, much like natural peanut butter, in order to keep out moisture and other contaminants.
For a long term option, sesame seeds can be frozen in an airtight container.
Some benefits of proper food storage include eating healthier, cutting food costs and helping the environment by avoiding waste.
