Does sesame oil expire?

In this brief guide, we are going to answer the question “does sesame oil expire” with an in-depth analysis of whether or not sesame oil expires. Moreover, we are going to discuss the shelf life of sesame oil, the proper way to store sesame oil, and whether or not you can reuse the sesame oil.

So without much ado, let’s dive in and figure out more about it.

Does sesame oil expire?

Whether or not sesame oil expires depends upon several factors including what do you mean by expired sesame oil. If you mean that the flavor and taste of sesame oil will change after a certain time then, like all other foods sesame oil can expire.

What we mean by expired sesame oil is that such sesame oil will go rancid or go stale and it won’t have the same aroma and flavor as that of fresh oil. Moreover, it will also lose its antioxidant content.

It is worth mentioning that you will find a “best by” or “ best before” date is written on the bottle of your sesame oil instead of the expiration date. The “best by” or “best before” date that is written on the bottle of sesame oil refers to the quality rather than safety so sesame oil doesn’t necessarily go bad immediately after the best before date. It is the time during which you can enjoy the peak quality and flavor of sesame oil but you can still use sesame oil that is past this date as long as it was stored properly.

There are certain indicators that you should keep into consideration to find out whether your sesame oil has gone rancid or not.

Sesame oil can go rancid and it can develop that unpleasant rancid aroma that is noticeable if you take a sniff test of the sesame oil (it won’t have the otherwise nutty aroma of the fresh sesame oil). 

Moreover, if you feel some unpleasant taste or rancid taste while taking a bite of food fried in sesame oil then it means that your oil has gone rancid and it is better to discard it.

The nutrient profile of the sesame oil that has gone rancid is also degraded and it has lost most of its antioxidants.

How long does sesame oil last?

When it comes to the sesame oil, unopened sesame oil lasts for about 18 months or even more if it is stored in a cool, dry, and dark corner of your pantry away from direct sunlight and heat. It is the time during which you can enjoy the best quality of the sesame oil which means that you can still use properly stored sesame oil even after this time.

Moreover opened sesame oil lasts for about 6 months if it is stored in a cool, dry, and dark corner of the pantry away from direct sunlight and heat. Moreover, refrigeration can increase the shelf life of the sesame oil and sesame oil lasts for about 1 year when it is properly stored in the fridge at or below 40 degrees Fahrenheit. You should keep in view that refrigerated sesame oil can become cloudy and can even solidify.

It is worth mentioning that these figures are just the estimated shelf life of sesame oil and sesame oil can even last for more than this, provided that it was stored properly. 

How to properly store sesame oil?

  1. You should store your sesame oil away from direct sunlight and heat. As sunlight and heat can increase the rate at which sesame oil can go rancid or stale.
  2. You can store the unopened sesame oil easily in a cool, dry, and dark corner away from direct sunlight and heat. Thus you can store sesame oil in your pantry or kitchen cabinet. You can store the sesame oil in the pantry even after it has been opened and it can last for a long time there. 
  3. Moreover, you can also refrigerate your sesame oil to prolong its shelf life.
  4. You should close the lid of the bottle containing sesame oil as soon as you have poured the oil that you need so that it will minimize air or obnoxious agent exposure of your sesame oil.

Can I reuse sesame oil after frying?

When it comes to reusing sesame oil after you have fried something like fish, chicken, or any other thing in it, you have to keep some things in mind. 

Firstly, you should let the oil cool and afterward strain the sesame oil before storing it to get rid of the leftover particles of the previous food that you fried in it.

Moreover, there is no hard and fast rule regarding how many times you can reuse the sesame oil, but you should keep in mind that the quality and taste of oil deteriorate with each time you fry something in it. 

Therefore you will notice that you won’t get the same flavor of the fried food after you have fried for the fourth time in the same sesame oil as you got when you fried something in it for the first time. 

Thus, the time when you start to feel a noticeable difference in the taste and smell of the food that you fried in your reused sesame oil, you should discard the oil.
