Does Olive Oil Go Bad?
Olive oil is a popular cooking oil that is known for its health benefits. It is a good source of monounsaturated fats, which are considered to be heart-healthy.
However, like all oils, olive oil can go bad. The shelf life of olive oil varies depending on the type of olive oil and how it is stored. Here is a look at how long olive oil lasts and how to tell if it has gone bad.
How to Tell If Olive Oil Has Gone Bad
To tell if olive oil has gone bad, look for a change in color, smell, or taste. Rancid olive oil may be cloudy, dark, or have a strong, unpleasant odor. It may also taste bitter or sour. If you notice any of these changes, it is best to discard the olive oil.
Olive oil is a healthy and versatile cooking oil, but it can go bad if it is not stored properly. Here are a few ways to tell if olive oil has gone bad
Appearance
Olive oil that has gone bad may become cloudy or dark. It may also separate, with the oil and water becoming two distinct layers.
The cloudiness or darkness may be caused by oxidation, which is a chemical reaction that occurs when olive oil is exposed to oxygen. Oxidation can also cause the oil to become rancid.
Smell
Olive oil that has gone bad will have a strong, unpleasant odor. It may smell like crayons, putty, or something else that is not pleasant. The smell may be so strong that you can smell it even before you open the bottle.
Taste
Olive oil that has gone bad will have a bitter taste. It may also taste sour or off. The bitterness may be so strong that you can taste it even before you swallow the oil.
If you notice any of these signs, it is best to discard the olive oil. Do not use it, as it may make you sick.

How Long Does Olive Oil Last?
The shelf life of olive oil varies depending on the type of olive oil and how it is stored. Extra virgin olive oil, which is the highest quality olive oil, has a shorter shelf life than other types of olive oil.
Extra virgin olive oil will typically last for 12 to 18 months when stored in a cool, dark place. Other types of olive oil, such as virgin olive oil and pure olive oil, can last for 18 to 24 months when stored properly.
