Using Cooking Spray In An Air Fryer: Safe Or Not?

Air fryers are a popular kitchen appliance that allows users to cook crispy and delicious food without using excessive amounts of oil. However, one common question that new air fryer owners often ask is whether they can use cooking spray to prevent food from sticking to the basket. While it is possible to use cooking spray in an air fryer, it is generally not recommended as it can damage the non-stick coating and affect the taste and quality of the food.

Cooking spray can damage the non-stick coating of an air fryer

Cooking spray can be a handy tool in the kitchen, but it's important to know that it's not suitable for all applications. One appliance that you should never use cooking spray with is an air fryer.

Cooking sprays contain lecithin, an emulsifier, which can build up on the surface of your air fryer's basket or rack over time. This build-up results in sticky spots that are hard to remove and can degrade the non-stick coating, impacting the appliance's performance. The lecithin can also cause staining and discolouration, which may be difficult to clean.

Additionally, cooking sprays have a low smoke point, and the lecithin will start to break down at the high temperatures used for air frying. This can cause gunk to build up on your equipment, potentially ruining the surface.

So, what can you do to prevent sticking in your air fryer? Instead of reaching for the cooking spray, opt for a high smoke point oil like avocado, canola, peanut, sesame, or sunflower oil. A little goes a long way—just lightly coat the air fryer basket or your food with oil using a non-aerosol spray bottle, a silicone brush, or a paper towel.

You can also try using air fryer liners, such as disposable parchment paper or reusable silicone liners, which don't require any oil at all. Metal racks or trays that keep your food elevated are another great option, as they prevent your food from touching the bottom of the basket and sticking.

While cooking spray may seem like a convenient option, it's important to remember that it can cause more harm than good when used with an air fryer. By using alternative methods to prevent sticking, you can keep your air fryer in good condition and ensure your food comes out perfectly crisp and delicious.

Cooking spray can cause smoke and an unpleasant odour

The lecithin in cooking sprays is less stable than high smoke point oils and will deteriorate at the temperatures used for air frying, which is typically 180°F to 400°F. This can result in a build-up of gunk in your air fryer, specifically on the tray or basket, and can potentially ruin the surface. When oil reaches its smoking point, it begins to break down and produces an unpleasant odour and vapours.

To avoid this issue, it is recommended to use a high smoke point oil such as avocado oil, sunflower oil, or refined olive oil, and apply it sparingly to the air fryer basket using a non-aerosol spray bottle, a silicone brush, or a paper towel. You can also choose to oil your food directly before placing it in the air fryer, ensuring you use an oil with a high smoke point.

Additionally, it is important to clean your air fryer regularly to prevent the build-up of food residue and grease, which can also cause smoke and odour issues. It is recommended to allow the air fryer to cool, remove the basket and drip tray, wash with soapy water, and wipe down the interior with a damp cloth to ensure all grease is removed.

By following these steps, you can help prevent smoke and unpleasant odours caused by cooking spray in your air fryer, ensuring a more enjoyable and smoke-free cooking experience.

Cooking spray can cause discolouration and an off flavour

Cooking Spray and Air Fryers: What You Need to Know

Air fryers have become increasingly popular due to their convenience and ability to cook food without the need for large amounts of oil. However, with this new appliance comes the question of whether cooking spray can be used as a substitute for oil.

Cooking spray is a convenient product that has been around for over 50 years and is often used to grease pans and baking dishes. While it may seem like a good idea to use cooking spray in your air fryer, it is important to understand the potential drawbacks.

Discolouration and Off Flavours

Cooking sprays can cause discolouration and produce a slightly off flavour in your food when used in an air fryer. This is because cooking sprays often contain soy lecithin, an emulsifier that is less stable than high-smoke-point oils. When exposed to the high temperatures of an air fryer, soy lecithin can deteriorate, leading to discolouration and an unpleasant taste.

Additionally, cooking sprays contain other ingredients such as anti-foaming agents and propellants, which can affect the taste and smell of your food. The propellants can also build up on the surface of your air fryer over time, creating a sticky residue that is difficult to remove and can degrade the non-stick coating.

Alternative Options

To avoid discolouration and off flavours, it is recommended to use high-smoke-point oils such as avocado oil, sunflower oil, or coconut oil. These oils can be lightly coated on the air fryer basket using a non-aerosol spray bottle, a silicone brush, or a paper towel.

Another option is to oil your food directly before placing it in the air fryer. This ensures that your food has a light coating of oil, preventing it from sticking to the air fryer surface without affecting the appliance itself.

In conclusion, while cooking spray may seem like a convenient option for your air fryer, it is best to avoid it due to the potential issues it can cause. By using alternative options such as high-smoke-point oils and oiling your food directly, you can maintain the quality and taste of your air-fried dishes while preserving the condition of your appliance.

Cooking spray can cause a sticky residue

Cooking spray can be used for air fryers, but it is not recommended. Cooking spray can ruin the non-stick coating of the air fryer basket or racks. The lecithin in the spray will start to build up over time, resulting in a sticky residue that is hard to remove and can degrade the coating. This will cause the non-stick surface to no longer work as intended.

Cooking spray is made up of oil, lecithin (an emulsifier), dimethyl silicone (an anti-foaming agent), and a propellant. The lecithin in the spray will build up over time, resulting in a sticky residue. This residue can be difficult to remove and will degrade the non-stick coating.

To avoid causing a sticky residue, it is recommended to use a high smoke point oil like avocado, canola, peanut, sesame, or sunflower oil. Lightly coat the air fryer basket with oil using a non-aerosol spray bottle, a silicone brush, or a paper towel. You can also oil your food directly instead of spritzing the basket.

If cooking spray has already caused a sticky residue, there are a few ways to try and remove it. One method is to soak the basket in hot, soapy water to soften the build-up and then lightly scrub it with a non-scratch scrubber. Other products that may be effective include Bar Keeper's Friend, a powder cleaner/polish, and Everbake Food Release Spray from King Arthur Flour.

Using oil directly on food is an alternative to cooking spray

In short: no. Cooking spray can damage the non-stick coating of your air fryer.

If you want to avoid the risk of damaging your air fryer, you can try using oil directly on your food instead of spraying it onto the appliance. This method is supported by several online sources and is recommended by Martin Bucknavage, an expert in food safety in the Penn State Department of Food Science. Bucknavage suggests using a high smoke point oil such as avocado, canola, peanut, sesame, or sunflower oil.

• Use a non-aerosol spray bottle, a silicone brush, or a paper towel to lightly coat your food with oil.
• If you're cooking something sticky like honey or peanut butter, coat your measuring cups with oil first to prevent sticking.
• If you're using a pan or basket, you can also coat it with a thin layer of oil, but this may not be necessary as many foods won't stick to the pan.
• If you're looking for a more flavourful experience, use olive oil or butter instead of cooking spray.
• If you're cooking for someone with a soy allergy, avoid using cooking spray as it often contains soy lecithin.
• If you want to avoid GMOs, look for an organic brand of cooking spray or use an alternative oil.
