This article will explore the shelf life of sesame oil, discuss why some varieties might be more resistant to becoming rancid than others, and even touch on recipes where sesame oil adds subtle flavor as a finishing touch.

What’s Sesame Oil?

Sesame oil is an edible vegetable oil derived from sesame seeds.

It is high in polyunsaturated fats which can help reduce levels of bad cholesterol, and has a pleasant, nutty taste.

As a cooking oil it is suitable for baking, stir-frying, shallow frying and deep-frying, as it has one of the highest smoke points among vegetable oils – meaning it can be heated to quite high temperatures without burning or producing off-flavors.

Sesame oil offers not just culinary benefits but also potential health benefits; its anti-inflammatory properties can help with pain relief and control some allergies, while its antioxidants may help protect the body from damage caused by free radicals.

Such a versatile condiment is no wonder why sesame oil is loved globally.

How to Store Sesame Oil?

Storing sesame oil properly is essential to ensuring its peak flavor and freshness.

For optimal results, store the oil in a cool dark area at room temperature away from direct sunlight; an airtight container is also beneficial.

Furthermore, it is wise to keep the bottle capped when not in use, as this will help prevent humidity or other outside contaminants from entering the bottle.

It is also a good idea to purchase small portions of sesame oil so that you can use it up before it has a chance to go rancid, which can happen after about six months or longer depending on how you store it.

By following these steps and keeping your sesame oil safe and accessible, you can enjoy its delightful flavor for weeks if not months.

Sesame oil has a shelf life of about 2 years if it is stored properly.

If you are not sure if your sesame oil has gone bad, there are a few signs to look for.

The first sign is the color of the oil.

If the color has changed from its original light amber color to a dark brown, it has most likely gone bad.

Another sign is the smell of the oil. If it smells rancid or bitter, it is time to toss it out.

Finally, if the texture of the oil has changed and it has become thick and sticky, it has probably gone bad and should not be used.

Can You Freeze Sesame Oil?

Freezing sesame oil is a great way to extend its shelf life and guarantee maximum flavor.

Sesame oil is typically made from toasted or untoasted sesame seeds and can vary in color from light yellow to a dark, reddish brown.

While it may seem counterintuitive to freeze sesame oil, it rarely crystallizes in the freezer and instead maintains its original consistency with little change.

When storing for long periods of time, freezing is the best way to ensure that the flavor of sesame oils remain intact as other methods of storage can result in oxidation leading to spoilage.

To prepare your sesame oil for the freezer, carefully measure out portions and store them in an airtight container before putting it away.

This way you can enjoy all of your favorite dishes with the same great taste even if months or years have passed.

If the oil starts to smoke or smells burnt, it’s time to toss it out.
