Air fryer acrylamide is real, but the full story is mixed. Some studies found far less than in deep frying, and others found the same or more.

The machine is not the main cause. Heat, time and the colour of your food matter most.

This guide shows what each study found and how to cut acrylamide at home. Every number links to its source.

Does Acrylamide Form in an Air Fryer?

Quick answer: Yes. Acrylamide forms when starchy foods like potatoes are heated above about 120 °C. Air fryers cook at up to about 200 °C, so some forms. It comes from the food, not the machine, so no air fryer is acrylamide-free.

The US FDA explains it simply. "Acrylamide forms from sugars and an amino acid (asparagine) during certain types of high-temperature cooking, such as frying, roasting, and baking" (FDA).

Hong Kong's Centre for Food Safety puts the start point above 120 °C (CFS Hong Kong). It adds that "higher temperatures and longer cooking time will result in higher levels of acrylamide regardless of the cooking method".

Low-heat, wet cooking is different. "Boiling and steaming do not typically form acrylamide", says the FDA.

Why care at all? The WHO cancer agency rates acrylamide as "probably carcinogenic to humans (Group 2A)" (IARC).

EFSA says its concern is based on animal studies (EFSA, 2015). For the cancer question in depth, read Air Fryer and Cancer: Acrylamide Risk Explained.

Air Fryer vs Deep Fryer: What the Studies Found

Quick answer: The studies disagree. Three lab studies found less acrylamide in air-fried food, from up to 47% less to about 90% less. A 2024 study found slightly more in the air fryer, and EFSA reports consumer tests with 30-40% more. Heat and time explain most of the gap.

Study	Food	Air fryer vs deep fryer
Sansano et al., 2015	Potatoes, 180 °C	About 90% less in the air fryer
Frontiers in Nutrition, 2022	Frozen French fries	Up to 47% less in the air fryer
Lee et al., 2020	Chicken breast, thigh, wings	Lower in the air fryer (n.d. to 3.49 vs n.d. to 6.19 µg/kg)
Navruz-Varlı and Mortaş, 2024	Potato sticks	Highest in the air fryer, but no real difference
EFSA summary of industry and consumer tests	French fries	30-40% more in hot-air fryers

The biggest drop came from Spain. The paper says "Air-frying reduced acrylamide content by about 90% compared with conventional deep-oil-frying" (Sansano et al., 2015).

A 2022 study of frozen fries found up to 47% less than deep frying at 180 °C for 6 minutes (Frontiers in Nutrition, 2022).

A Korean chicken study agreed. It found that "air frying could reduce the formation of acrylamide and PAHs in chicken meat in comparison with deep-fat frying" (Lee et al., 2020).

Then came a 2024 study from Türkiye. It reported that "The highest acrylamide content was found in potatoes cooked using the air fryer" (Navruz-Varlı and Mortaş, 2024).

But the authors also wrote that "the difference between the acrylamide contents of the potatoes according to the cooking methods was not statistically significant".

Europe's food safety body adds a warning. "Tests by industry and consumer organisations indicate hot-air fryers generally produce 30-40% more acrylamide than conventional deep oil fryers" (EFSA).

The honest answer: An air fryer is not automatically lower in acrylamide. It can be lower when you keep the heat and time in check.

Air Fryer vs Oven vs Deep Fryer vs Boiling

Quick answer: In the one study that tested all three on the same potatoes, the air fryer gave 12.19, the deep fryer 8.94 and the oven 7.43 µg/kg. The gaps were not statistically significant. Boiling and steaming do not typically form acrylamide at all.

Method (2024 potato study)	Heat and time used	Acrylamide (µg/kg)
Air fryer	200 °C for 15 min	12.19
Deep fryer (500 mL oil)	180 °C for 10 min	8.94
Oven	As set in the study	7.43
Boiling or steaming	100 °C	Not typically formed (FDA)

Look at the heat settings. The air fryer ran at 200 °C for 15 minutes, the setting its maker suggested for fries (Navruz-Varlı and Mortaş).

The deep fryer ran cooler, at 180 °C for 10 minutes. So the test was not quite like for like.

All of these numbers are tiny. A review noted that every average sat below the lab's 18.20 µg/kg limit of quantification, so they cannot be told apart (Ceran Serdar, 2024).

In its words, the values fall below that limit, "indicating that they cannot be differentiated from each other". For a fuller look at the two machines, see Air Fryer vs Oven for Indian cooking.

By the numbers: The EU benchmark for French fries is 500 µg/kg, per the 2022 Frontiers study. The 2024 home-style fries were far below it.

Why the Results Differ: Heat, Time and Colour

Quick answer: Acrylamide rises with temperature and cooking time. In air-fried fries, it rose steadily from 180 °C to 200 °C and from 12 to 24 minutes. EFSA says frying above 175 °C can greatly raise levels.

The 2022 fries study tested many settings. Acrylamide and other browning by-products "all increased steadily with air frying temperature and time" (Frontiers in Nutrition, 2022).

EFSA notes that for French fries, frying above 175 °C can lead to greatly increased levels (EFSA).

An air fryer sits the food close to a hot coil, with hot air at up to about 200 °C (CFS Hong Kong). Run it on high for too long and the edges get dark fast.

A Korean consumer group made headlines for this reason. It tested fries air-fried at 200 °C and found high levels (CFS Hong Kong).

So the question is not which machine. It is how hot, how long and how brown.

Acrylamide in Indian Snacks

Quick answer: Packaged deep-fried Indian snacks can carry far more acrylamide than home air-fried fries. A Kerala study found up to 4,245.6 µg/kg in potato chips. A study of 51 Indian snacks found up to 6,391 µg/kg in deep-fried foods.

CSIR-NIIST scientists tested 80 samples of fried snacks from shops in Kerala (Shamla and Nisha, 2014).

Snack (Kerala shops)	Acrylamide range (µg/kg)
Potato chips	82.0 to 4,245.6
Jackfruit chips	46.2 to 2,431.4
Sweet plantain chips	24.8 to 1,959.8
Plantain (banana) chips	14.7 to 1,690.5

A separate study tested 51 popular Indian snacks. Deep-fried foods ranged from 372 to 6,391 µg/kg (Defence Life Science Journal).

These were different labs and foods, so this is not a direct test. Still, it shows that the chips and namkeen you buy matter more than the machine at home.

How to Avoid Acrylamide in an Air Fryer

Quick answer: Soak cut potatoes for 15 to 30 minutes and pat them dry. Do not max out the heat. Cook in batches, shake the basket, and stop at a golden yellow colour, not brown.

Go for gold. The UK food agency says to "aim for a golden yellow colour or lighter when frying, baking, toasting or roasting starchy foods" (Food Standards Agency).
Soak potatoes first. FDA says "Soaking raw potato slices in water for 15-30 minutes before frying or roasting helps reduce acrylamide formation during cooking" (FDA). Pat them dry.
Keep the heat moderate. Use the lower end of your recipe's range. The 2022 study saw more acrylamide at 200 °C than at 180 °C.
Do not overload the basket. Hong Kong's food safety centre says to cook in batches to prevent overloading (CFS Hong Kong).
Check early and shake. Edges brown first. Pull the basket out a few minutes before the timer and look at the colour.
Store potatoes as you like. The FSA now says fridge storage "doesn't materially increase acrylamide forming potential" (FSA). A cool, dark shelf is also fine.

Soaking helped in the 2024 study too. Potatoes soaked for 10 minutes had less acrylamide than washed ones in all three methods (Navruz-Varlı and Mortaş).

Choosing an Air Fryer With Acrylamide in Mind

Quick answer: No air fryer is acrylamide-free, whatever the box says. Pick one with a temperature control you can turn down, and ideally a window so you can watch the colour.

InstaCuppa does not make air fryers. These three are in stock on Amazon India as of 28 October 2026.

Wide temperature range: the Judge by Prestige InstaAir 4 L Digital Air Fryer. Its listing says you can set 80 °C to 200 °C.

Watch the colour: the Havells Prolife Brio 4.2 L Air Fryer. Its listing names a see-through window and adjustable temperature and time.

Simple controls: the Philips NA120/00 4.2 L Air Fryer. Its listing says you can easily adjust time and temperature.

The Bottom Line on Air Fryer Acrylamide

Quick answer: An air fryer uses far less oil, and it can make less acrylamide than a kadhai. It does not always do so. Lower heat, shorter time, soaked potatoes and a golden colour cut acrylamide in any method.

EFSA says acrylamide may raise cancer risk for people of all ages. It notes that "children are the most exposed age group on a body weight basis" (EFSA, 2015).

So keep their chips and toast light. Eat a varied diet, and boil or steam starchy foods often.

Frequently Asked Questions

Does acrylamide form in an air fryer?

Yes. It forms in starchy foods like potatoes when they are heated above about 120 °C. An air fryer runs hotter than that, so some acrylamide forms, just like in an oven or a kadhai.

Is there an acrylamide-free air fryer?

No. Acrylamide comes from the food, not the machine. No air fryer can stop it. What helps is lower heat, shorter time, soaking potatoes and stopping at a golden colour.

Air fryer vs oven: which makes less acrylamide?

In the 2024 potato study, the oven gave 7.43 and the air fryer 12.19 µg/kg. The gap was not statistically significant. Both were at very low levels.

Is air-fried food healthier than deep-fried food?

It uses far less oil. For acrylamide, the studies disagree. Some found much less in the air fryer, while EFSA reports tests that found more.

Does soaking potatoes reduce acrylamide?

Yes. FDA says soaking raw potato slices in water for 15 to 30 minutes helps. Drain them and pat them dry before cooking.

Is acrylamide only in potatoes?

No. FDA says it is found mainly in plant foods, such as potato products, grain products and coffee. Meat, fish and dairy form little or none.

Are children more at risk from acrylamide?

EFSA says children are the most exposed age group for their body weight. Cook their chips and toast to light gold, and give them a varied diet.

Does air-fried chicken have acrylamide?

Very little. In one study, air-fried chicken had up to 3.49 µg/kg and deep-fried chicken up to 6.19 µg/kg. A besan or bread coating adds more starch, so keep it golden.
