The short answer is that light, heat, and oxygen exposure cause olive oil to go bad. These factors cause oil to deteriorate quickly, regardless if it is sitting in your kitchen, on a store shelf, or in a distributors warehouse.
Does light destroy olive oil?

Can you store olive oil in light?
Olive oil should be stored in a cool, dry, dark cupboard, away from the heat and light. Choose a spot in the kitchen that’s away from the oven. The best temperature for storing oil is 57 degrees, though room temperature, or 70 degrees, is also okay. How: For a longer shelf life, don’t store oil in direct sunlight.
What happens if you light olive oil?
Olive oil can catch on fire once it heats to its flash point or smoke point. Olive oil which is reaching this level will usually boil or pop. If it appears to smoke or burn, it’s at a dangerous stage and should be removed from heat.
Does olive oil need to be in the dark?
Even a few weeks of light exposure will accelerate the aging of olive oil. To slow this process, it’s a good idea to store your oil in a dark, cool cabinet instead of on a countertop, which is likely brighter and warmer.
Does olive oil go rancid in the sun?
Extra virgin olive oil will oxidize quickly and lose much of its health properties if you leave it by the heat or in the sun. Keep olive oil away from windows and away from the stove.
Why extra virgin olive oil is not good for cooking?
While EVOO is fairly stable to heat in terms of its fat composition, it is quite unstable to heat in terms of its phenol and polyphenol composition. Recent studies show that phenols and polyphenols in EVOO—for example, hydroxytyrosol or luteolin —are not stable to heat and degrade relatively quickly.
What is the best way to store olive oil?
Industry experts recommend storing the oil at between 55 and 60 degrees Fahrenheit for best results. Storing it at the usual room temperature of about 70 degrees Fahrenheit is ok, but if your kitchen is routinely warmer than that, refrigerate the oil for best quality.
What is the best container for olive oil?
The best containers for olive oil storage are glass (especially tinted glass), ceramic, porcelain, or non-reactive metals such as stainless steel. Do not store olive oil in containers made of reactive metals such as copper or iron.
Is olive oil better in glass or plastic?

Is olive oil unhealthy when heated?
The flavor compounds in Olive Oil are delicate and will evaporate when heated. Furthermore, heating olive oil does not damage the health benefits but it will make the olive oil lose flavor. Overall, Olive Oil is safe to cook with. Heating Olive Oil will not destroy the health benefits or turn olive oil unhealthy.
Does olive oil become carcinogenic when heated?
Myth: Olive oil produces carcinogens when it’s heated. Fact. What’s true is that when any cooking oil is heated to the point where it smokes (its smoke point) it breaks down and may produce potentially carcinogenic toxins. Different oils reach their smoke points at different temperatures.
What is the difference between extra virgin olive oil and light olive oil?
Unlike regular olive oil, extra-virgin olive oil is unrefined (not processed with chemicals or heat), and it has much less oleic acid than regular olive oil (meaning its fat hasn’t been broken down). It has a distinctive rich color and a notably peppery flavor.
Should olive oil be light or dark?
Keep in mind that the best quality olive oil is – or should be – sold in dark bottles or in tins, as light is the enemy to olive oil, especially unrefined olive oil. An olive oil’s color, much like that of a wine, indicates its flavor profile, rather than its quality.
Should olive oil be refrigerated once opened?
Even after being opened, refrigeration is not necessary as long as stored properly. However, if you won’t be using an opened bottle for several weeks, refrigeration may help preserve the oil until you need it. Just be sure to let it warm to room temperature afterward so that it is completely liquid before using.
Should extra virgin olive oil be stored in a dark bottle?
You should store olive oil in a dark coloured bottle made from glass. The darker hue will stop light from reducing the oil’s lifespan. You can also use a stainless-steel container. Whichever method you opt for, they will both protect your olive oil from light exposure.
How does light affect rancidity?
Rancidity is the oxidation of oils or fats in the food that causes a foul odour and flavour. When unsaturated components of a fatty substance are exposed to sunlight, they can break down into esters, volatile aldehydes, ketones, alcohols, and hydrocarbons, some of which have foul odours.
How long is olive oil good for once opened?
Opened olive oil will usually keep for 18 to 24 months when stored in the pantry. Should olive oil be refrigerated? An opened bottle of olive oil can be refrigerated to extend its shelf life – refrigeration is recommended in hot, humid environments.

- Keep olive oil in a dark room, or store it in light-proof packaging (like drums or BIB totes).
- Avoid exposure to air.
