How Long Does Sesame Oil Last? Find Your In-dept Answer Here!

Sesame oil is a popular ingredient in many cuisines. It is particularly used in Japanese, Korean, Chinese, Thai, and Vietnamese dishes.

Extracted from sesame seeds, you can already imagine how sesame oil tastes like – yes, it’s very similar to eating sesame seeds (without the crunch, of course).

Since sesame oil is a type of vegetable oil, their tastes are very similar – quite nutty in smell and taste. So, if you are not that good in tasting oil, you might find it hard to distinguish vegetable-type oils.

In this article, you will learn about sesame oil (in general). I am telling you right now that it’s a very good type of oil. However, once it goes bad and becomes rancid, it can be very dangerous to your health.

How long does sesame oil last? You will know the answer to that question (and much more) in this post, so keep on reading.

How Long Sesame Oil Lasts

Generally, sesame oil will stay in good condition for 4 to 8 months. This will depend on many conditions such as storage and exposure to heat.

If left in the pantry, a sealed container of sesame oil will last for many many months (less than a year). However, if the container is already open, its life will shorten dramatically (about half the original lifespan of a sealed container).

Should you decide to keep sesame oil in the refrigerator, its life will be extended for a long time. In fact, if kept sealed, it can last for up to 2 years in the fridge. And again, if the container is already open, its overall lifetime will be reduced.

So, you see, storage really plays a very important role in making sesame oil last longer.

Storing Sesame Oil Properly

Keep the points I listed below in mind when storing sesame oil.

  • check-square-o
    Store sesame oil in a cool, dry place to maintain its quality for a long time.
  • check-square-o
    Keep sesame oil away from heat (direct sunlight, heater, oven, stove, etc.).
  • check-square-o
    It’s quite alright to keep unopened sesame oil in the pantry. Once opened, however, it would be best to put it in the refrigerator to prolong its life and maintain its quality.
  • check-square-o
    Once opened, keep sesame oil in a tightly sealed container. Air, moisture, pollutants (dirt, dust, insects) will cause it to deteriorate quickly and spoil.

Shelf Life of Sesame Oil

Like I said, the shelf life of sesame oil will depend on a lot of factors. If your goal is to extend its life while making sure that it’s safe for consumption, keep the following things in mind when dealing with sesame oil.

  • spinner
    Check the Production date and “Best by” date. These dates will give you an idea as to how long the sesame oil will last (and stay in its best quality). Typically, sesame oil will be in its best condition for about 1.5 to 2 years after the production date.
  • spinner
    When you open a container of sesame oil, remember that the seal is already broken. Opening it will expose the oil to elements (air, moisture, etc.) – and so, it will only stay in good quality for about 4 to 6 months.
  • spinner
    Even though you have stored sesame oil properly, it can still go bad (since a lot of factors are involved in keeping it fresh). Therefore, once you discover that the sesame oil has already turned rancid, discard it and throw it away (it has already gone bad).

How to Tell if Sesame Oil is Bad

Using spoiled sesame oil will ruin your dish and also affect your health. No, we don’t want to use sesame oil if it has already gone bad. With that in mind, remember these things:

  • times-circle
    Observe changes – Any change in color, smell, and taste of sesame oil should alert you that it’s no longer of very good quality. While mild changes are acceptable, significant changes should be considered as warning signs that the oil is already bad.
  • times-circle
    Mold – If mold has already developed in the sesame oil, consider it to be contaminated. The oil is no longer safe for consumption at this stage.
  • times-circle
    Rancid oil – When sesame oil is already rancid-tasting, it should no longer be used. There are studies that say that consuming rancid oil can cause liver damage.
  • times-circle
    Solid when refrigerated – It’s only normal for sesame oil to turn solid when placed in the refrigerator. It will return to its original form (liquid) at room temperature.

Sesame Oil Recipes

Just to inspire you to make recipes that use sesame oil, I picked out a few easy-to-make dishes for you.

Sesame Oil Chicken

This dish is a very simple recipe. It makes use of the following ingredients:

  • Chicken
  • Sesame oil
  • Ginger
  • Soy sauce
  • Oyster sauce
  • Wine
  • Water
  • Caramel sauce
  • White pepper

The recipe basically calls for sautéing the pieces of chicken in sesame oil and adding sauce to it. You can pair this dish with rice or bread.

Sesame Noodles

This recipe is an Asian pasta dish. It’s very simple to prepare and all you need are the following ingredients:

  • Noodles
  • Sesame oil
  • Vegetable oil
  • Garlic
  • Soy sauce
  • Sugar
  • Rice vinegar

This pasta dish is almost a no-cook recipe as all you really need to cook is the noodles. For the sauce, you just need to combine the other ingredients in a bowl and pour it over the cooked noodles.

Cucumber Garlic Salad

Sesame oil is a popular salad dressing (next to olive oil, that is). If you want to use this type of oil in your fresh salad, know that it only requires the following ingredients:

  • Cucumber
  • Garlic
  • Sesame oil
  • White wine
  • Soy sauce
  • Pepper

In his recipe, you need to cut the cucumber into bite-sized cubes. The rest of the ingredients will then be used as the dressing – just mix it up and pour over the cucumber. This refreshing salad makes for a fine side dish. You can also make a variation of it by using more ingredients. Having a mandoline slicer (Amazon) will help you slice more vegetables for your salad.

Sesame Oil is Good for You

Let’s play it safe when consuming food (in this case, sesame oil) and only use them when their quality is good. I have already provided you with a guide on how to prolong the life of this type of oil (mainly through proper storage) and how to tell if it has already gone bad.

Keep in mind that the Best by date only serves as your guide. The ultimate test to whether sesame oil is still good and safe for consumption is if its taste, color, and smell are still the same (or just slightly different) when you first bought it.

To really play it safe, I would suggest using an unopened container of sesame oil within a year of buying it. And if it’s already opened, try to use everything up in about a month’s time (or put it in the refrigerator). Therefore, I advise against stocking up on too many containers of sesame oil if you seldom use it anyway.

As with other types of food, throw away sesame oil if it has already gone bad. It’s not that expensive, to begin with – and your health is way more important. Always remember that.
