Deep Fryers: How Long Can You Keep Frying?

Deep fryers are a great way to cook food, but how long can you keep the oil in them? The answer depends on several factors, including the type of oil, the temperature at which it is cooked, and how often it is used. Generally, once the oil has been opened, it should be kept for no more than three months, but there are ways to extend its life.

The type of oil used will affect how long you can keep it

Oil stabilizers can extend the life of frying oil, as can regularly cleaning your fryer to ensure no leftover food particles or residues are left behind. Food particles are one of the main reasons oil degrades, so it is important to remove them after each frying session.

The temperature at which you fry can also affect how long the oil will last. Aim to keep the temperature between 350°F and 375°F to avoid speeding up oil degradation.

Finally, it is important to note that oil should not be used past six months under any circumstances, as this can be harmful to your health.

How often you use the oil will impact its longevity

Oil stabilizers can also extend the life of your frying oil. These additives help maintain the oil's quality through multiple uses, saving you money in the long run. Regularly cleaning your fryer can also prolong the life of your oil. Ensure no leftover food particles or old oil residues are left before pouring in fresh oil for your next fry. With careful maintenance, oil in an outdoor deep fryer can typically be reused for five to six frying sessions.

It's important to note that constantly frying at too high temperatures can speed up oil degradation. Aim to keep your frying temperature between 350°F and 375°F. Food particles are one of the main culprits that contribute to the shortening of oil's lifespan. Breadcrumbs, batter, and other residues can accelerate the degradation process. To minimize this, use a skimmer to remove food particles after each frying session.

Additionally, using oils with a high smoke point can help extend the life of your deep fryer oil. Oils with a high smoke point are more stable when cooking foods at high heat. Some examples of oils with a high smoke point include canola oil, sunflower oil, peanut oil, and avocado oil.

The temperature you fry at will speed up oil degradation

Oil in a deep fryer generally lasts longer than in a skillet. However, there are several variables that can affect how long the oil lasts. These include the type of oil, how often it is used, and the temperature at which it is heated.

To extend the life of your oil, use oils with a high smoke point, such as canola oil, sunflower oil, peanut oil, or avocado oil. These oils are more stable when cooking foods at high heat. Additionally, regularly cleaning your fryer and removing food particles after each frying session can help to prolong the life of your oil.

As a general rule, once you've opened the oil, it should be kept for no more than three months. However, depending on how often you're using it and what foods you're frying, you may need to change your deep fryer oil sooner. For example, when frying breaded fish, it is recommended to change or filter the oil every two to three uses.

Food particles will shorten the oil's lifespan

The lifespan of oil in a deep fryer depends on several factors, including the type of oil and how often it is used. Generally, once opened, oil should be kept for no more than three months. However, food particles are one of the main culprits that contribute to the shortening of oil's lifespan. Breadcrumbs, batter, and other residues can accelerate the degradation process. Different foods release different quantities of particles and fluids into the oil. For example, when frying breaded fish, the oil should be changed every two to three uses, whereas when frying French fries or other non-breaded foods, the oil can be changed after six to eight uses.

To minimize the impact of food particles, it is important to use a skimmer to remove them after each frying session. Additionally, regularly cleaning your fryer can prolong the life of your oil. It is recommended to deep clean your fryer every three months to get rid of old oil and ensure no leftover food particles or residues are left before pouring in fresh oil.

Oil stabilizers can also help to extend the life of your frying oil. These additives help to maintain the oil's quality through multiple uses. Using oils that have a high smoke point can also help, as they are more stable when cooking foods at high heat. Examples of oils with a high smoke point include canola oil, sunflower oil, peanut oil, and avocado oil.

Finally, it is important to note that constantly frying at too high temperatures can speed up oil degradation. Therefore, it is recommended to keep your frying temperature between 350°F and 375°F. By following these tips, you can help to prolong the lifespan of your deep fryer oil and reduce unnecessary expenses.

To minimise this, use a skimmer to remove food particles after each frying session. Different foods release different quantities of particles and fluids into the oil. For example, when cooking French fries or other non-breaded foods like vegetables, change or filter the oil after six to eight uses. If you’re frying non-breaded meat or poultry, change or filter the oil after three to four uses. When frying breaded fish, change or filter the oil every two to three uses.

Additionally, regularly cleaning your fryer can also prolong the life of your oil. Ensure no leftover food particles or old oil residues are left before pouring in fresh oil for your next fry. With careful maintenance, oil in an outdoor deep fryer can typically be reused for 5 to 6 frying sessions. As a rule of thumb, it's safer to replace the oil after 3 to 4 uses for heavy-duty frying such as seafood boils or community cookouts.

Finally, once you’ve opened the oil, you should keep it for no more than three months. Always allow the oil to cool for approximately two hours before pouring it into a container, preferably through a cheesecloth. It’s also recommended to refrigerate the stored oil to maximise its longevity.
