Does Sesame Oil Go Bad?


Does sesame oil go bad?

Sesame oil will expire and then go bad. Of course, any kind of food changes over time, especially if it's been opened. Normal sesame oil also has a pleasant smell, while out-of-date sesame oil can smell like chili oil because harmful aflatoxin appears, which can cause nausea and vomiting after consumption.

Usually, manufacturers, like JOLION Foods, will print the production date and shelf life on packaging bottles, and it’s convenient for customers to check the label before using it.


How long does sesame oil last?

Sesame oil stored at room temperature usually expires after 12 months, while sesame oil stored in cold storage usually expires after 18 months. 

As you know, sesame oil deterioration is a gradual process that can not be accurately judged by smell. Therefore, for your health, it is best to eat in the shelf life for the shortest time to avoid long-term storage.

What's the best way to store sesame oil ?

Storing your sesame oil in refrigerator is never wrong. It would be better if you know these 3 tips :

1.Keep away from light: the characteristics of sesame oil are easy to oxidize and deteriorate when stored in light. So keep the sesame oil away from light. 

2. Not use the rubber plug: The rubber stopper will break the smell of the sesame oil after a time. When using the rubber stopper, you should use plastic to isolate its outside.

3. Use petite bottles: The smaller the bottle, the less air that can fit inside it. In a short period, you can use plastic bottles to store it. In contrast, in a long time, you’d better use glass bottles because oil and plastic chemical properties are quite similar so the chemical properties of the two substances can dissolve each other with a slow dissolution rate.
