Does Olive Oil go bad?
Some of those expensive bottles of olive oil in the back of your pantry are making you nervous about purging everything.
Inquiring minds want to know whether olive oil goes bad after a while, or if you can simply keep it on hand for as long as you need it.
Olive oil, despite its long shelf life, eventually goes bad.
In this article, we'll look at how long olive oil has a shelf life and how to tell if it's bad
Olive oil has a long shelf life because it is botanically classified as a fruit (Olea europaea). Olive oil, like fruits, has a shelf life, and so does the oil itself. At some point, it goes rancid and no longer tastes good.
After being
bottled, most olive oils have a shelf life of 18 to 24 months. Extra-virgin
olive oils are less refined and therefore last for a shorter period, between 12
and 18 months after being bottled.
Olive oils can develop acrid or bitter flavors if they are stored for longer than these periods.
The best-by or bottling date is printed on the back of some olive oil bottles. Label your bottles with the date of purchase if you don't see this option. To get a sense of how long it has been in your pantry, you can do this.
Ideally, you should store your olive oil in an airtight cabinet or refrigerator to keep it cool and dark.
Keep in mind that if you refrigerate it, it may get hazy and discolored. This is not a sign that your olive oil has gone rancid, but the rather typical response to colder temperatures.
A darker
glass, like dark green or amber, might help block off light, which accelerates
oxidation in the bottle. If you're going to the grocery store, keep an eye out
for this.
Cellular
oxidation accelerates the aging process. It can help break down fat molecules
more quickly in olive oil. Olive oil can be oxidized in other ways besides
light, such as by being exposed to oxygen or heat.
This is why it's best to keep your olive oil in a cold, dark place, and to make sure it's firmly capped when you open it.
It's also a
good idea to transfer your olive oil from a polyethylene container to a dark
glass or tin container if you wish to preserve it for a long time. It's getting
better and better as time goes on.
You may also want to buy smaller bottles of olive oil if you don't cook very often, especially if you're using a more expensive variety.
How to detect rancidity in olive oil
You can tell whether your olive oil is bad in a few different ways.
You can detect whether your olive oil has gone rancid by taking a small sip. You won't get sick from just a little taste.
Your olive oil should not be bitter, sour, or stale.
You can tell if it's not good olive oil by how it smells: Crayons, putty, or Elmer's glue can all be signs of bad olive oil.
A further indication that it has run its course.
How rancid olive oil affects your health
You won't get ill from using stale olive oil. But it could destroy your food by imparting a weird taste.
In addition,
olive oil is frequently praised for its numerous health benefits. Olive oil
that has gone rancid will lose some of its antioxidant power.
During oxidation, oxygen-containing molecules break down the oil's antioxidants by triggering a chain reaction of chemical events.
The nutritional value of rancid olive oil is reduced, yet it is safe to consume. However, fresh olive oil is best for getting the most out of its antioxidants.
A simple way
to tell if your olive oil is spoiled is to taste it.
Don't worry if your bottle has gone from a little old to a little rancid: You'll know. Pour a small amount into your mouth and take a whiff. To determine if something is rancid, consider how the scent compares to fermented fruit or rotting leaves on the ground. Elmer's glue-like odors have been attributed to it by some. Smell it first, then taste it without swallowing it if you're still unsure (just swirl it in your mouth). It's rancid if it has an "off" taste (like rotten nuts), is tasteless, feels greasy in your mouth, or has an odor.
Is it safe to use olive oil that has been past its expiration date?
It all depends on the situation. You won't get sick from cooking with rancid olive oil, but it's likely lost its nutritional value and antioxidants, as opposed to eating spoiled meat. In addition, your food will taste strange. Is the smell of your olive oil off? What do you think? Go straight ahead. Using something that smells and looks fine doesn't mean it won't lose some of its flavors over time.
Is it necessary to keep olive oil in the refrigerator?
What you're thinking is very understandable to us. The interior of my refrigerator is dark and comfortable. There's no way my olive oil is going to run out in there! Keeping olive oil in the refrigerator is an option, but keep in mind the oil may solidify due to the low temperature, making it difficult to use on the spur of the moment. As long as you don't live in an extremely warm or humid area, you may be able to increase the shelf life of your oil by using it more rapidly.
Getting rid of old or bad olive oil can be a difficult task!
As a result,
the oil in your olives has turned rancid. What's next? Pouring it down the
drain, or any other type of cooking oil is never a good idea. Your pipes and
city sewers could become blocked, resulting in the pollution of rivers in the
long run. Composting is out of the question. Transfer the bad olive oil to a
non-recyclable container (such as a cardboard milk carton or takeaway
container) and dispose of it in the garbage, as instructed by your local
sanitation department. Then, just like Ina Garten, go out and buy yourself a
new bottle.
