Toasted sesame oil typically lasts for 6 to 9 months after opening.
Here's a more detailed breakdown:
-
Unopened Toasted Sesame Oil: When stored in a cool, dark place, an unopened bottle of toasted sesame oil can last for several years, often up to its expiration date. Check the "best by" date on the bottle for the manufacturer's recommendation.
-
Opened Toasted Sesame Oil: Once opened, toasted sesame oil's flavor and aroma degrade over time. It is best to use it within 6 to 9 months for optimal quality.
-
Refrigeration: While not strictly necessary, refrigerating toasted sesame oil after opening can help extend its shelf life slightly by slowing down oxidation. Be aware that refrigeration may cause the oil to become cloudy, but this does not affect its quality; it will clear up at room temperature.
-
Plain Sesame Oil vs. Toasted Sesame Oil: Plain (non-toasted) sesame oil generally has a longer shelf life than toasted sesame oil. Plain sesame oil can last up to a year in the refrigerator after opening. The toasting process in toasted sesame oil makes it more susceptible to rancidity.
-
Signs of Spoiled Sesame Oil: Discard the oil if you notice any of the following:
- A rancid or off odor.
- A change in color or consistency.
- An unpleasant taste.
To maximize the shelf life of your toasted sesame oil:
- Store it in a cool, dark place, away from direct sunlight and heat.
- Keep the cap tightly sealed to prevent oxidation.
- Consider refrigerating it after opening, especially if you don't use it frequently.
- Use a clean utensil each time you pour oil from the bottle to avoid contamination.
By following these guidelines, you can ensure that your toasted sesame oil stays fresh and flavorful for as long as possible.
