How Often Should You Change The Oil In A Deep Fryer – 2022 Guide

Change The Oil In A Deep Fryer

Happiness is…..finding the lost fries at the bottom of your McDonald’s bag.

Well the answer to the question solely depends on the type of oil you are using, what are you frying, how much oil is expended to fry that portion of food, how frequently or how are you filtering the oil, how many times or hours the oil has been used, at what temperature the oil is put on, and how do you maintain the deep fryer.

What sorta oil is recommended?

Always go for oils that have a high smoke point at a specific temperature thereby making the food tastier.

At the “smoke point” the oil starts to break down and can have a foul odor or flavor. Following the smoke point, select oils that have maximum saturated and monounsaturated fats as they formulate the oil to be more stable at high heat.

And purchase oils that are conserved in a dark glass/canister, because it will reduce the exposure of sunlight.

  • Canola oil is widely used in deep frying as it has a high content of unsaturated fats, which gives rise to a healthier choice. The trouble with canola oil is they become distasteful very easily. So after unwrapping the canola oil bottle or container, always finish the bottle within six to twelve months for the best quality. Canola oil has an estimated smoking point at a temperature 450-degree Fahrenheit. So better use the oil at the precise temperature to hit the smoke point.
  • Furthermore, olive oils can endure around 18-24 months from the moment of manufacturing, wherein virgin olive oils can last around 12-18 months. If your oil has outperformed the time period, that means it is going to rancid any time. Olive oil strikes the appropriate smoke point at 410 degrees Fahrenheit.
  • Most jars of coconut oil in the United States come detailed with a “Best by” date, in order to prompt you that “ it’s time to renew your oil”. For those who aren’t aware, coconut oil has a naturally long shelf life. But however, you need to be cautious about expiration dates, maximum expiration a coconut oil could possibly last is, for approximately two years only if it is carried out with proper supervision.
  • Vegetable oils have made the dilemma more complicated because once when you have opened the oil, it has to be used for the first two to three months for the best quality. Occasionally it could last for one year relying on the way you are maintaining it. While these kinds of oil achieve the smoke point at 400 degrees Fahrenheit.
  • For an unopened avocado oil, it lasts for nine to twelve months when it is kept in the pantry. Whereas the opened bottles can be used within six months for good quality. Avocado oil attains the smoke point at 375-400 degrees Fahrenheit.

Factoid: Olive oil has the longest shelf life.

So yeah, what are you and your family’s most preferred oil?

Presume you are frying battered food, always discard the excess batter to thwart debris in the oil. Do remember to pat dry the food before dipping it into the oil in order to avoid havocs. Always handle the deep fryer gently and don’t overload your food in a row to have a quick snack. Dumping all the food at the same time tends to ravage the oil very easily.

  • For french fries, other non-breaded items, and veggies, change the oil after 6-8 uses.
  • Whereas the oil should be replaced after the use of 3-4 times for breaded, meat, poultry, and crumbly foods.
