Many people use cooking oils. They are commonly used to fry foods. Vegetable oil is one of the most popular types of cooking oils.
Many people have a bottle of vegetable oil in the cupboard, using it for months on end. Unopened, these bottles tend to last for about two years before going bad.
Vegetable oil is a kitchen staple for many people. Often used in frying, vegetable oil is widely used.
Though many keep them in their cupboards for ages, vegetable oil, like all food, has an expiration date.
Can vegetable oil turn bad? What is vegetable oil like? Discover the answers below.
Will Vegetable Oil Turn Bad?
Quick Answer: Yes, vegetable oil will go bad. Luckily, it has quite a long shelf-life, so you won’t have to worry about the oil going bad quickly. Like most types of oil, vegetable oil will last for approximately 2 years before it expires. However, this is only the case if the bottle of oil is unopened.
When you purchase a bottle of vegetable oil, you should check the expiration date.
This is because different bottles will have different use-by dates, which have been determined by the makers.
When it has been opened, the vegetable oil will only last for roughly one year. After this amount of time, the oil’s quality will decline.
Luckily, this is quite a lengthy time. Consequently, you can easily use the vegetable oil before it expires.
What Is Expired Vegetable Oil Like?
Most oils can be used even once the used-by date has been passed. The reason for this is that even though the oil is no longer at its highest level of quality, it will not hurt to use it.
On the other hand, we do not recommend using expired vegetable oil. This is because oil starts to develop an unpleasant smell. Its taste will also be disagreeable.
Many people have compared expired vegetable oil to paint. Moreover, others have said that it develops a sour and acidic taste. These are the most obvious signs that oil has expired.
If you don’t want to taste the oil, which is very understandable, you can instead pour a small amount of vegetable oil onto a plate.
Then, give the oil a good sniff. If it smells different from how it usually is, then this is a red sign of expiration.
You can also visibly tell if vegetable oil has gone off because its color will change. Specifically, the oil will develop a darker color. The light yellow or gold color becomes deeper.
Another indication of expiration is mold. When oil turns bad, mold tends to occur around the bottle’s seal.
If you consume mold, you can expose yourself to symptoms of illness, such as respiratory issues.
If you notice these changes, it is best to discard the oil. After all, you are unlikely to have a pleasant eating experience.
How Should Vegetable Oil Be Stored?
One way of ensuring that your vegetable oil lasts for a long time is to store it properly. Here are our top tips for storing this type of oil:
- Keep the oil out of direct sunlight. Ideally, vegetable oil should be kept in a cool and dry place. Cupboards are ideal for this, as they keep the oil at a cool temperature.
- When not in use, keep the cap of the bottle closed at all times. When the battle is open, oxidation can occur. Exposure to oxygen will only speed up the expiration. If you break the cap, you can find an alternative. You can also invest in oil bottle spouts, which can be found online and in some stores.
- Do not keep the oil near the hob or any other sources of heat. This heat can also speed up the vegetable oil’s deterioration. Not to mention, placing the oil near a heat source is a safety hazard.
By following these simple rules, you can give your vegetable oil the best chance of lasting for a long time.
Of course, you should also pay attention to the use-by date if you wish to avoid expired vegetable oil.
Can You Be Sick From Vegetable Oil?
You are unlikely to be ill from expired vegetable oil. However, that does not mean that we advise using expired vegetable oil.
This is because you can experience sickness and stomach aches. If you continue to use gone-off oil, you can also suffer from some long-term health conditions.
This is because of the presence of free radicals. If your body receives high levels of free radicals, you can experience negative effects.
As the body gets older, its ability to fight free radicals reduces. Thus, this is a particularly serious issue for older people.
Consequently, if you observe any of the aforementioned signifiers of expired vegetable oil, then you must refrain from using it.
