It is a question that has been asked for centuries: what is the shelf life of olive oil?
The answer is not a simple one, as the shelf life of olive oil depends on a variety of factors, including the type of oil, the storage conditions, and the method of preservation. However, in general, olive oil has a shelf life of about two years.
Quality and color of olive oil:
olive oil comes in a variety of colors ranging from green to gold and even dark brown or black – the color is determined by the olive itself and not the pressing process or the quality of the oil and has nothing to do with its quality as consumed as a food or for its health benefits)… the quality is determined by the amount of “healthy” free fatty acids it contains which are measured scientifically by what is known as the orac value which stands for oxygen radical absorbance capacity–which is a measure of how much free radicals are absorbed after contact with the oil or fat being evaluated!
The higher the number the better the oil/fat is for your health in terms of health and age fighting properties!!
It also matters whether the oil is virgin or not and of course the price per pound which reflects all the costs that go into producing a high quality product as it does with a low quality mass produced cheap junk sold to the public at cheap prices.
Is it OK to use expired olive oil?
When it comes to olive oil, there are a lot of misconceptions out there. One of the most common is that the color of the oil determines its quality.
This simply isn’t true!
The color of olive oil is determined by the olive itself and has nothing to do with the pressing process or the quality of the oil. The quality of olive oil is determined by the amount of “healthy” free fatty acids it contains. These are measured scientifically by what is known as the orac value.
The orac value is a measure of how much free radicals are absorbed after contact with the oil or fat being evaluated. The higher the number, the better the oil or fat is for your health in terms of age-fighting properties. It also matters whether the oil is virgin or not.
Virgin olive oil is the highest quality and has the most health benefits. Of course, all of this comes at a price. High quality olive oil is more expensive than mass-produced, low quality olive oil.
But it’s worth it to invest in your health!
The shelf life of olive oil is largely determined by its temperature. If olive oil is stored at high temperatures, its shelf life will be shorter. However, if olive oil is stored at lower temperatures, its shelf life will be longer.

Oxygen has negative effects on olive oil when exposed directly as oxygen molecules oxidize some parts of vegetable oils such as lecithin (sophisticated fat found mainly in oils). This leads not only flavor but also changes texture as well as quality; oxidized vegetable oils become hard (or oxidized fats) when cooled or when exposed at room temperature for long periods; furthermore some fats become yellowish when exposed directly (even after storage), therefore oxygen levels must be considered when buying or storing any type of edible oil . Oxidation occurs naturally due changes associated with time/temperature during processing as well as storage conditions; oxygen is essential for combustion reactions such as heating oils but excessive exposure results oxidation (spoilage).
In addition exposure during cold weather slows oxidation because heat transfer slows down but some fats can spoil even if stored cold or refrigerated if exposure occurs (refrigerator temperatures have been known affect freshness negatively).
Shelf life also differs per olive oil:
if you will eat your lecithin (sophisticated fat found mainly in oils) then it won’t affect your health and can be used daily but to know the oxidation in oil, there must be an experiment. You need to do this procedure:
(1) Add 1 or 2 tablespoons of olive oil into an oven-safe glass container. Set the temperature to 350˚F for about 45 minutes, stirring from time to time.
(2) After 45 minutes remove the bottle from the oven and let it sit overnight in a cool area away from direct light exposure. The next day perform taste tests on your sample. If oxidized flavors exist try adding some additional olive oil back into sample if available so you can reduce oxidization rates in the initial stage of heating.
Otherwise simply discard these samples after they are finished oxidizing and enjoy!
How can you know if your olive oil has gone bad or not?
you should be able to smell any rancid aromas coming from the dish after the above testing is completed if done carefully enough or if the lemon treatment was used properly and no extra oxygen was available during the experiment time before “aging” took place in the fridge the next morning.. If the test shows no scents there might not be anything to worry about since old ingredients may become difficult to find or have less and less flavour due to degradation over time especially if you don’t have a constant supply of those products and the aroma of them might have faded out because they are normally older batches or just a cheap product that hasn’t stood the test of time well and become worse quality as time passes by even if left in cool and dark conditions over the years prior to this experiment been conducted on them so this can change the results slightly and some storage might help reduce the aging process and make it less likely for any tastes to develop… either sulphur based compounds or other chemicals may develop at various stages of storage and concentration levels can occur as some of them even might be colourless and not detectable by the human nose unless the odour level is very high and causing unpleasant smells which are then noticeable such as from produce where fruit is picked when it changes colour and develops lots of pigments throughout time or vegetable can start
As we age, our taste buds change and we become less sensitive to certain flavors.

Should olive oil be refrigerated after it is opened?
Olive oil is a fatty food. It should be kept in a fridge.
How do you store olive oil long term?
One way to store olive oil is to place it in a refrigerator. The olive oil will remain fresh and odorless in the fridge. If you want to store olive oil for a longer period of time, you can place it in a sealed container.
You can also store olive oil in a dark place to preserve its color and flavor.
Is olive oil supposed to be kept in a dark container?
Olive oil does not need to be kept in a dark container, but it should be stored in a cool, dark place.
What is the best container to store olive oil?
While olive oil doesn’t go bad or become harmful as long as its seal remains intact ,it can still lose some freshness if not stored properly This will allow air exposure which oxidizes or spoils oil quickly . The best place is an opaque bottle . A clear glass bottle may show traces of sediment at room temperature but may still look beautiful when placed on your kitchen shelf .
An opaque bottle is better as it will not allow light exposure which oxidizes olive oil quickly . Light exposure destroys essential nutrients such as Vitamin E that prevent oxidation . Olive oil can be stored at room temperature ,for long term storage refrigerate after opening bottle .
But if refrigeration isn’t possible use olive oil container that is tightly sealed . Olive oil storage container should have two-way valves that prevent spills from getting into olive oil container . These containers are not only convenient but they are also leak proof containers thus allowing you easy transportation without any spillage issues while travelling .
Does olive oil go bad unopened?
When I carry my jar around, I can’t tell if the food inside it is expired or not.
Does this mean that oil from unopened bottles goes bad?
3) From a technical perspective, if you buy oil from outside or in plastic containers, is it safe to store it in the refrigerator?
Can it last forever?
This one is pretty obvious; let me cover everything in a series of questions and answers. First, some things that the Consumer Product Safety Commission doesn’t ask about, because they don’t make it into its instructions on product safety.
The exact questions to ask are on each product label and the CPSC website.
Why should you not refrigerate olive oil?
Olive oil has a shelf life of 3 years. To preserve it, store it in a cool, dark place. It should not be refrigerated.
In conclusion, olive oil has a very short shelf life. This means that it doesn’t last nearly as long as other oils like soybean or sunflower seed oil. However, because it’s made from olives, it contains lots of antioxidants and nutrients that help keep it fresh for longer periods of time.
So if you want to use olive oil regularly, buy extra bottles and store them in the fridge. That way, you won’t run out of it as quickly.
