Deep Fryer Oil: How Long Before It Turns Rancid?

Deep fryer oil can be stored for up to six months, but there are a few things to consider if you want to keep it for that long. Deep-fried food is not the healthiest option, and reusing oil can be even less healthy, so it's best to use fresh oil when you can. You should also store oil in a dark, cool place, and filter it to keep it as long as possible.

How to store deep fryer oil: keep it in a dark, cool place, like a cabinet, and make sure it's sealed

Deep fryer oil should be stored in a dark, cool place, like a cabinet, and should be sealed. It is important to store oil properly, rather than leaving it exposed in the fryer.

Oil should be discarded when the smoke point drops, or if it is too dark, or if it develops a foul odour. It should not be used past six months under any circumstances.

One user reported that they use their oil about ten times and rarely deep-fry anything. They let the oil cool down, then put the lid on the pan and leave it overnight. They then pour the oil through a fine mesh sieve into a large mason jar, seal it, and put it in an upper cabinet.

Another user reported that they use their fryer once a month and change the oil a couple of times a year. They also store it properly, rather than leaving it exposed in the fryer.

It is recommended that oil is filtered to keep it as long as possible. Bad oil can be detected by a few ways, like smoke point or smell.

How to tell if deep fryer oil has gone bad: if it's too dark, has a foul odour, or has passed its smoke point, throw it out

Deep fryer oil should be stored in a dark, cool place, in a container with a tight lid. It should be filtered and cleaned before being stored. It should not be used past six months under any circumstances.

There are a few ways to tell if deep fryer oil has gone bad. Firstly, if the oil is too dark, it has likely gone rancid. Rancid oil will also have a bitter, tart or foul odour. It may also foam on the surface when hot. If the oil has passed its smoke point, it should be thrown out.

How often to change deep fryer oil: it depends on how often you use it, but generally, it should be changed every six months

How often you should change your deep fryer oil depends on how often you use it. If you rarely deep fry anything, you can get away with changing it a couple of times a year. However, if you use it more often, you should change it every five or six uses, or every six months.

To keep your oil in good condition for as long as possible, you should store it somewhere dark and cool, and make sure you filter it. You can also extend the life of your oil by switching to tallow (beef fat) or rendered pig fat (lard) as saturated fats last longer than poly-unsaturated fats.

You should always discard your oil if it reaches its smoke point, becomes too dark, or develops a foul odour.

How to extend the life of deep fryer oil: switch to tallow (beef fat) or rendered pig fat (lard) as these last longer than poly-unsaturated fats

Deep fryer oil should be stored in a sealed, light-proof container in a cool, dark place. It can be stored for up to three months, or six months maximum, but should be discarded if it starts to foam or has a foul odour, taste or smell.

To extend the life of deep fryer oil, you can switch to tallow (beef fat) or rendered pig fat (lard) as these last longer than poly-unsaturated fats. Saturated fats are more stable and less likely to go rancid, so they can be reused more often. Tallow was used by McDonald's until a few years ago, and was the secret to the flavour of their fries. However, due to health concerns, most operators have now changed to vegetable-based frying oils.

It's important to note that reusing oil is not healthy, as it will still contain some of the cooked substance. Even if the oil is strained and cooled in the fridge, it will not be as healthy as using fresh oil.

To keep your deep fryer oil for as long as possible, you should filter it and clean the sides of the fryer before putting the oil back in. You can also store it in the fridge, which will improve the quality.

How to properly reuse deep fryer oil: fast-food chains reuse oil for the same day or a few days, and they store it properly, not in the fryer

Deep fryer oil can be reused for the same day or a few days, as is the case with fast-food chains. However, it is important to store it properly, not in the fryer.

To keep your deep fryer oil usable for as long as possible, it is recommended to store it in a dark, cool place, such as inside a cabinet or a fridge. It should be filtered and kept away from heat sources like the stove or oven. Additionally, it is important to clean the container before storing the oil to prevent particulate build-up.

The oil should be discarded when it reaches its smoke point, becomes too dark, or develops a foul odour. It is also recommended to discard the oil after six months, even if it has not been used, to maintain gastrointestinal health.

Some people choose to discard the oil after a few uses, depending on what is being fried. For example, one person reported discarding the oil after about five or six uses, while another person reused the oil about ten times but only deep-fried occasionally.
