How Long Does Oil Last in a Deep Fryer?
Oil is a kitchen staple and cooking necessity for nearly any recipe that requires heat. Deep frying in particular calls for large amounts of oil to completely submerge the food being cooked.
There are many benefits to cooking with oil. Your choice of cooking oil can have plenty of health benefits (such as coconut oil and olive oil), like healthier skin, hair, and digestive system.
Most oils have a long shelf life and if stored properly can last for years. Certain infused oils may even taste better the longer they are left to sit. You can reuse certain oils after frying food in them to cook other foods, which is both frugal and can help fuse flavors together.
You can even store used oil in a deep fryer for reuse, as long as you have the right type of deep fryer for this. Most new deep fryers are made with an airtight lid that keeps your used oil from being contaminated with dirt, dust particles, or bacteria in the air that can spoil the oil. As long as you have an airtight seal, you can store and reuse oil in your deep fryer for up to several weeks. You will also want to be sure that you are storing your deep fryer with oil in it in a cool and dark place to best prevent spoilage.
How Long Can I Store Oil in a Deep Fryer?
There are many factors at play when determining how long oil can safely be stored in a deep fryer, including what food was fried in it, the type of oil you used, and whether or not you strained the oil last time you cooked in it.
Oils used to cook meat will typically go bad sooner than oils used to cook vegetables. The more times you reuse the same oil, the more the oil’s smoke point will decrease.
What Will Happens When I Reuse Oil?
As you use the oil repeatedly, it will darken in color. If you notice the food you are frying darkens much more quickly than usual, this is a sign that the oil has gone bad and should not be used. If the oil is too dark, discard and start with new oil.
Which Type of Oil is Best to Store in a Deep Fryer?
Many types of oil will store well in a deep fryer, but perhaps the best one is peanut oil. Not only is it a wonderful cooking agent for many foods, but it can also add a lot of health benefits and is great for use in a deep fryer due to its high heat temperature.
What’s the Best Way to Store Used Oil?
If you do not store it properly, oil can go bad after just one use. Putting the oil in an airtight container and storing in the refrigerator or freezer is the best method to prevent spoilage. Storing oil this way can make it last for weeks or even months.
Filtering the oil is another step in storing used oil that is particularly important if you plan to leave it in the deep fryer for reuse. Using a strainer and cheesecloth, or a coffee filter for a small amount of oil, you can clean the oil of any bits of food or particles left behind from last use.
How Can I Tell If My Cooking Oil Has Gone Bad?
Even if you have taken every precaution your oil can still go bad without you knowing it.
One way to recognize bad oil is the color. Oil shouldn’t look dark, but it is natural for oil to darken some with reuse. If it is several shades darker than its original color, though, then it needs to be thrown out as it could be unsafe for consumption. Compare the stored oil to the oil in the bottle it came from to be sure.
You will also be able to recognize bad oil by its smell. If it smells bad, or even just off from its usual fragrance, throw it out.
What are the Benefits of Reusing Cooking Oil?
Reusing your cooking oil is a great way to save both time and money. You will get more uses per every bottle of oil you purchase if you reuse the oil multiple times. It saves you time by not having to go to the store as often, and by not having to pour the oil at the beginning of cooking if you store it in the deep fryer.
