How long do Sesame Seeds last:
The answer to this question depends on how the seeds are stored. Normally they should be stored in a cool and dry place, away from direct sunlight and moisture. If stored under room conditions and the aforementioned methods followed, they can last for 1 – 2 years with its quality intact. However, some people say these seeds can last for 3 – 4 years as well, all of them being estimates. Sesame seeds have been said to last longer if frozen. Freezing the seeds can almost multiply the shelf life by 2. Sesame oil from the seeds, however, does not last very long. Just like olive oil, sesame oil has very high amounts of unsaturated fats. Unsaturated fats are healthy but do not last forever. The shelf life of sesame oil is 6 months, after opening the bottle it may last a few months more.
How to know if Sesame seeds have gone bad:
As many people might assume that Sesame Seeds go bad by the Best By date on the package of the seeds. Technically, Sesame seeds do not go bad making them inedible but they just lose their potency. This means they lose their aroma and flavour, making them useless. The best by date only accounts for the quality of the seeds and not the expiry date. The seeds can be continued to use even after the best by date is over.
However, Sesame seeds that have been kept open for days can have a rancid smell or flavour. Unlike poppy seeds and Chia seeds, Sesame seeds do not taste bitter when they go bad. They have got a rather sour taste. Raw fresh sesame seeds would have a nutty taste and an earthy aroma and when toasted on a pan this intensifies, bad sesame seeds do not have that and when bad seeds are toasted the aroma is exchanged with an intense rancid smell. The best method to find out if the sesame seeds have gone bad or not is to crush a bit of it and rub it on your palm. If you do not get any fragrance, then the seeds have lost its potency and it is time to get a new bag of sesame seeds for your kitchen.
