Can sesame oil go bad?

Yes, sesame oil can go bad as it has the ability to go rancid after a certain time. Not only a sesame oil that has gone bad will have a rancid odor and taste but it can also cause serious health implications when it is consumed in large quantities over a long period of time.

The rancid smell is a musty smell that is unpleasant and quite noticeable. 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.

What are the health implications of consuming rancid oil?

The excessive consumption of rancid oil has been seen associated with free radicals production in the body that can cause certain harmful effects. The rancid oil has carcinogenic free radicals in it and if someone consumes such oil in large quantities then these free radicals will mess up the normal body functioning. 

Short-term usage of rancid oil won’t cause any significant health issues but if you consume rancid oil over a long period of time then it can result in an increase in the number of free radicals in the body that can in turn damage the cells of the body, proteins, and DNA.

Is it safe to use sesame oil after the “best by” or “best before” 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.

What is the shelf life of sesame oil?

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.
