Air fryers work by circulating hot air around a food item to create the same crispiness as in traditional fried foods.
Air fryers accomplish this by removing high-fat and high-calorie oils from the cooking process.
By using just 1 tablespoon of cooking oil rather than multiple cups, a person can produce similar results as they would with a deep fryer with a fraction of the fat and calories.
Researchers state that air fryers use heated air that contains fine oil droplets to take the moisture out of the foods. The result is a product that has similar characteristics to fried foods, though with significantly lower levels of fat.
Like many other cooking methods, air-frying triggers a chemical reaction the Maillard effect that improves the color and flavor of air-fried food.
