What is the Shelf Life of Sesame Oil?

Now that we know how to identify bad sesame oil, let's talk about its shelf life. Like many other types of oils, sesame oil has an expiration date.

The quality of the oil, when it was opened, and how it is stored can all affect its shelf life.

Does Sesame Oil Expire?

Technically, sesame oil doesn't have an expiration date like dairy products, but it does change slowly over time.

The process of rancidification, where the fat molecules in the oil oxidize, causes an unpleasant flavor and smell.

So while it may not be harmful to consume rancid sesame oil in small amounts, it's best to avoid it due to potential long-term health risks.

Best Before Date for Sesame Oil

Freshly purchased sesame oil should ideally be used within a year. However, once opened, the clock starts ticking.

Plain sesame oil can last up to nine months in the pantry or a year in the fridge, while opened toasted sesame oil should be used within six to nine months.

These are rough estimates, and the actual shelf life depends on factors such as storage conditions, oil quality, and the age of the oil when it was opened.

How to Preserve the Freshness and Quality of Sesame Oil?

Now that we know the shelf life of sesame oil, let's discuss how to preserve its freshness and quality. Proper storage is key to keeping your sesame oil in top-notch condition.

Sesame Oil Storage Methods

To ensure your sesame oil stays fresh, keep it in a cool, dark place away from heat sources and direct sunlight. Light, heat, and air can cause the oil to go rancid more quickly.

So, find a cozy spot in your kitchen pantry or cupboard for your sesame oil to hang out.

How does rancidity affect sesame oil?

As we mentioned earlier, sesame oil can become rancid over time.

The process of rancidification is gradual and takes months, so you may not notice any changes if you use the oil regularly. But trust me, once it turns rancid, you'll definitely know!

How Long Does Sesame Oil Last after the Expiration Date?

Properly sealed and stored sesame oil can last longer than its expiration date. However, it's always a good idea to do a quick sniff and taste test before using it.

If the oil has a rancid smell or taste, it's time to say goodbye and grab a fresh bottle.

How to Avoid Sesame Oil Spoilage?

To avoid sesame oil spoilage, it's important to understand the difference between plain and toasted sesame oil and how to properly preserve them.

The Difference between Plain and Toasted Sesame Oil

Plain sesame oil is a light-colored oil with a subtle flavor and aroma, while toasted sesame oil has a stronger, nutty flavor and aroma. It's essential to choose the right type of sesame oil for your recipes to ensure the best flavor.

Proper Preservation of Sesame Oil

To keep your sesame oil in tip-top shape, remember to store it in a cool and dark place, tightly seal the lid to keep air out, and avoid mixing new oil with older oil. By following these simple steps, you'll be able to enjoy the full freshness and quality of your sesame oil.
