  • Dry texture: If your tahini paste has dried out and become hard, it is no longer safe to eat. This could be due to improper storage or leaving it open for too long.
  • Unpleasant smell: If your tahini has a sour or off-putting odor, it is best to get rid of it. This could be a sign of bacterial growth and consuming it could lead to food poisoning.
  • Rancid taste: A sharp or rancid taste is a clear indication that your tahini has gone bad and should not be consumed.
  • Expiration date: Always check the expiration date on the jar. If it has passed, it is best to discard the tahini.
  • Length of storage: If you have had the jar of tahini opened for more than six months, it is recommended to throw it away, even if it appears to be fine.
  • Changes in consistency: While changes in consistency may occur in tahini, such as separation of oil and solids, this does not necessarily mean it has gone bad. Simply mix it thoroughly before using.

To prevent your tahini from spoiling quickly, make sure to store it properly by tightly sealing and refrigerating it after opening. It is also recommended to use it within four weeks for optimal quality. Additionally, homemade tahini will have a shorter shelf life due to the absence of preservatives.

Opt for an airtight container

When storing tahini, use an airtight container made of glass to prevent exposure to oxygen and moisture.

This will help preserve its freshness and prevent it from becoming rancid.

Keep in a cool, dry spot

Tahini should be stored in a cool, dark place, away from sources of heat like direct sunlight or stovetops.

A kitchen cabinet or pantry is an ideal location for storing tahini.

Refrigerate after opening

While unopened tahini can be stored at room temperature, it is best to refrigerate it once opened to extend its shelf life.

This is particularly important for homemade tahini, which lacks preservatives found in store-bought versions.

Freeze for extended storage

To keep tahini for an even longer period of time, it can be frozen.

Place the tahini in an airtight container or freezer bag and store it in the freezer for up to 6 months. Remember to thaw before using.

Discard if it tastes off

Tahini has a long shelf life, but it can spoil. Signs that your tahini has gone bad include a unpleasant smell or taste, and the presence of mold. If your tahini has a bitter or sour taste, it should be discarded.

How to Tell If Tahini Is Bad?

When trying to determine if your tahini has gone bad and may no longer be safe to consume, there are a few key signs to look out for.

These indicators include:

Moldy Appearance

Keep an eye out for any green or black spots around the edges of the jar or in the crevices of the top, as this is a clear indication that your tahini has gone bad.

Not only can mold growth affect the taste and texture of the tahini, but it could also pose a health risk due to contamination.

Dry Texture

Typically, tahini has a smooth and creamy texture. However, if it appears to be completely dry or clumpy, this could be a sign that it has spoiled.

This could be caused by exposure to air or prolonged storage.

Sour or Off Smell

Fresh tahini has a mild nutty aroma, so if you notice a strong sour or off smell, this is a clear indication that your tahini has gone bad.

A noticeable change in smell should raise a red flag and prompt you to discard the product.

Rancid or Sharp Taste

Similarly, if your tahini tastes rancid or has a sharp taste, it is likely that it has gone bad. Fresh tahini has a rich and nutty flavor, so any significant changes in taste should not be ignored.

Exceeded Expiration Date

If your jar of tahini has been opened for an extended period, like a year or longer, it is best to throw it out.

Over time, tahini can spoil and become unsafe to consume.


In conclusion, tahini is a cherished and versatile condiment that adds a delectable nutty taste to any dish.
