Is it possible for cooking oil to become bad?
Cooking oil, like any other form of oil, may become rancid. The word “cooking oil” refers to a variety of seed and vegetable oils that are used in cooking. The shelf life of these oils varies depending on how refined they are, their composition, and how they are stored. Canola oil, sunflower seed oil, safflower oil, olive oil, and mixed vegetable oil have an unopened shelf life of roughly two years. Once the bottle is opened, their shelf life is reduced to around a year. if the oil is properly kept
Corn oil, sesame oil, and many nut oils have a shelf life of just a year if left unopened. If properly kept, these oils will last between four and nine months once opened. Because certain oils degrade more rapidly, it’s crucial to test them before using them to prevent a nasty surprise!

How to Know If Your Cooking Oil Is Bad
Cooking oils will not develop mildew or rot, but they will go bad eventually. Rancidity is the most evident symptom when cooking oil has gone bad. The stench of rancid oil is fairly strong and unpleasant. Always check for rancidity in your oil before using it. It is not suggested to consume rancid oil since it might be harmful to your health in the long run. Rancid oil may cause intestinal pain and give your meal a bad flavor in a short period of time.
Oils that have been refrigerated may get hazy and harden somewhat, but this does not indicate that they have gone bad. Simply set the oil out at room temperature to revert to a liquid condition. When some oils, such as olive oil, are kept at lower temperatures, they may seem to have sediment, although this is only a response to the cooling and does not suggest deterioration.
How to Keep Cooking Oil Safe
Cooking oil that hasn’t been used should be kept in a firmly sealed container in a cold, dark location. The oil’s shelf life will be extended as much as possible by storing it away from light and heat. Once the oil has been opened, refrigerating the firmly sealed container will prevent it from getting rancid for as long as possible, albeit the shelf life will stay at one year.
Cooking oil should not be frozen to increase its shelf life. Freezing the oil will not prolong its shelf life and would just hasten the spoilage process once it thaws. Because freezing and thawing may alter the structure of the oil, it will oxidize more quickly and turn rancid.
When buying a bottle of cooking oil, look for one that is stored in a dark glass or opaque container. By blocking away light, the oil will not deteriorate as soon. Of course, since many cooking oil brands come in transparent plastic containers, it’s critical to preserve the bottle correctly once you get home. Check the dates on the bottles as well, and aim to purchase an oil with at least a year left on its shelf life. This ensures that you get the most out of your oil bottle.
