Types of Avocado Oil

In order to identify which avocado oil you are using and how to detect signs of spoilage, you must know the types of avocado oil.

Avocado is not seen as often in households, which still makes most of us unaware of the types and storage methods.

Ideally, there are two types of avocado oils available:

  • Unrefined
  • Refined

Unrefined Avocado Oil has a very distinct color and texture. It may taste and smell buttery and may also seem a bit thick and sticky.

Unrefined ones are usually labeled as extra virgin or virgin avocado oil, depending on the refining procedures. It has a more greenish, yellowish tinge as well.

On the other hand, refined avocado oil seems like any other normal vegetable oil. It has a neutral taste and color. Therefore, refined versions can be easily used as replacements for any other vegetable oil, and you may not quite notice the difference either.

Now that we know about the types let’s focus on whether avocado oil turns bad easily and how you can store them.

Most edible items don’t last forever. Be it in the case of vegetable oils like avocado as well. Avocado oil is often confused with olive oil for its looks and properties. However, they have different shelf lives due to the amount of polyunsaturated fatty acids.

Avocado oil has fewer polyunsaturated fatty acids than olive oil. This slows down the rancidification process in avocado oils. However, as it turns old, you would notice a change in color and taste, as the fatty acid content does not entirely prevent it from getting spoilt.

However, if you have a half-opened bottle of avocado oil at home, or notice a pack of avocado oil on the shelf, knowing the signs of spoilage will help you determine if the oil is safe for use or not.

Once the oil gets old and deteriorates, it loses its properties and benefits, rendering it useless.

We help you figure out all the details you need to know about storing and using Avocado oil to maximize its properties and benefits.

Different brands of Avocado Oils have different shelf lives. The actual shelf life is mentioned in each packaging. However, in general, unrefined avocado oils last less than the refined varieties. 

Unrefined oils have higher fatty acid content, making them healthier for use. But, they are also prone to get rancid quickly.

On the other hand, refined oils undergo several processes and may even contain preservatives. This increases the overall longevity of these varieties.


How long does unopened Avocado Oil last?

  • Lasts till the “best before” date, as mentioned
  • Lasts for 9-12 months if stored in the refrigerator


How long does Avocado Oil last once opened (unrefined)?

  • Lasts for 4-6 months on the shelf
  • 6-9 months in the refrigerator


How long does Avocado Oil last once opened (refined)?

  • Lasts for 9-12 months on the shelf
  • 12-15 months in the refrigerator

Various oil brands carry out various refining processes that spoil avocado oil’s original quality and properties. Therefore, most oils start deteriorating even before their mentioned expiry date.

However, if you read the ‘best before date on the package label, the oil is still suitable to be used after the best before date. The only minus part would be a slight decrease in its original properties and benefits.


Signs of Spoilage | How to tell if avocado oil goes bad?

How to Tell if Avocado Oil Has Gone Bad

Avocado oil comes with a long shelf life. However, one needs to understand how to detect whether their avocado oil has gone wrong. Especially if you use it regularly, then detecting signs of spoilage can get difficult because you are used to the distinct taste.

Here is what you need to check as signs of spoilage for avocado oil:


Avocado oil is generally light green to transparent in color. If you notice that the avocado oil has turned darker, or looks unusual than its original packaging color, then the avocado oil is spoilt. Of course, there are other tests to confirm if the oil is spoilt or not.

Often, if you store the oil in the fridge, you may see a cloudy and different texture of the oil as compared to what it was originally!

Tip: In such cases, you can allow the oil to come to room temperature or heat it a bit to remove the cloudiness. The oil is still safe to use.

Smells Bad

Under normal circumstances, unrefined avocado oil has a buttery smell, whereas refined varieties have no smell in particular. If you have ever smelled or tasted spoilt vegetable oil, then avocado oil is more or less similar to vegetable oil when it comes to spoiling!

Also, if you get a typical chemical-like smell, which is sour and unpleasant, then your avocado oil is not worth using anymore. Some claim it has an off, play dough-like smell, while some claim it smells like acetone (nail polish remover).

These smells may be more prominent in the unrefined varieties as they tend to turn rancid easily. In the case of refined avocado oil, you may need to check several times using several methods before you can confirm if it is spoilt.

Tastes Rancid

Sometimes the oil may not have changed color or appears normal and smells fine. It is always advisable to take a taste test. If there is any chemical-like taste or something that is sour or tastes off, it’s time to discard the avocado oil.

Author’s Note: Remember that the off-taste may be more prominent in the unrefined varieties as they contain a high amount of fatty acids than their refined counterparts.


Slight exposure to heat or light may cause an unwanted oxidation reaction in avocado oils. Therefore, always look for a brand that offers opaque packaging. If you see an avocado oil with a transparent pack, it’s bound to deteriorate more easily when stored at home or on the pantry shelf.

Extra virgin avocado oils/unrefined versions are better stored in opaque glass bottles to maintain the properties and freshness of the avocado oil. Else, it is always risky to buy the ones with transparent packaging!

Best Before Date/Expiry Date

The best before date is essential since this determines how soon you can use the avocado oil to avail the best of its benefits. The oil can still be used after the best before date, just that the properties and benefits of the oil may be compromised.

Once you notice any of these above factors like bad taste, smell, or appearance, then the oil has definitely crossed its expiry date.

What Happens if you eat Expired Avocado Oil

You may not immediately fall sick if you consume spoilt avocado oil. If avocado oil is spoilt, it has basically developed toxic radicals.

Therefore, to avoid the accumulation of toxic radicals in the body, it’s best to avoid consuming any expired oil or spoilt avocado oil.

Sometimes, the oil may go bad even before its expiry or the best before date. This is due to the various refining processes carried out these days that lead to the early deterioration of processed edible oils. At such times, it is advisable to check for signs rather than stick to the expiry date.


How to Store Avocado Oil?

Storing avocado oils is not much of a hassle. These oils have a very good shelf life which makes them last longer, just like other vegetable oils.

However, avocado oils can turn rancid pretty easily and may develop toxic radicals. Therefore, the best way to store them on the shelf is to keep them in an opaque, air-tight bottle.

Any exposure to air or light can quicken the rancidification process, rendering the oil useless and causing early degradation.

Store at cool temperatures, away from exposure to sunlight, in a dark bottle preferably.

Another way to increase the shelf life of avocado oil is to store it in the refrigerator or freezer.

You can store avocado oils in any opaque bottle at the door of the refrigerator to maintain the temperature and increase its shelf life. This will help you preserve its quality for at least 8 months.

If you want it to stay more than a year, then you have to store it in a freezer.

Just make sure to seal the bottle properly and maintain a temperature of 35 to 37 degrees Fahrenheit in the freezer.

Storing oil in the refrigerator can change the texture and solidify the oil. In such cases, you can warm the oil or allow it to reach room temperature before consuming it. It is relatively easy to defrost avocado oil by applying direct heat and melting it.

What are the Alternatives to Avocado Oil if it has gone bad?

How stable is avocado oil?

As compared to other vegetable oils, avocado oils are very stable and do not need frequent refrigeration or preservatives. It has a naturally long shelf life. This is because it has low amounts of polyunsaturated fatty acids, which can cause rancidification.

Rather, it has more amount of monounsaturated fatty acids that make it quite stable, easy to store, and healthier to use.
