Air fryers typically use Teflon (PTFE) non-stick coating rather than stainless steel for several reasons:
Non-stick cooking surface: The primary advantage of Teflon coating is that it provides a non-stick cooking surface. This means that food is less likely to stick to the surface, making it easier to cook and clean up afterward. With a non-stick surface, you can reduce the need for oil or cooking spray, promoting healthier cooking.
Even heat distribution: Teflon coatings have good heat-conducting properties, which helps ensure even distribution of heat across the cooking surface. This results in consistent and uniform cooking of the food.
Prevents rust and corrosion: Teflon is resistant to corrosion, which is particularly beneficial in a high-moisture cooking environment. Stainless steel alone might be prone to rusting when exposed to moisture, affecting the performance and longevity of the air fryer.
Lightweight and cost-effective: Teflon-coated cooking baskets or trays are often lighter than their stainless steel counterparts. This makes the air fryer more manageable and easier to handle. Additionally, Teflon coatings are generally less expensive than stainless steel, contributing to lower production costs and potentially making air fryers more affordable for consumers.
Despite the advantages, Teflon coatings do have some limitations. They may not be as durable as stainless steel, and they can be susceptible to scratching if not handled and cleaned properly. Scratched Teflon can potentially release harmful fumes at high temperatures, which is a concern for some users. It is essential to follow the manufacturer's guidelines for care and maintenance to prolong the life of the Teflon coating and avoid potential health risks.
Stainless steel versions of air fryers do exist and may appeal to those who prefer cooking without non-stick coatings or have concerns about the durability of Teflon. However, they might require more oil or cooking spray to prevent food from sticking to the surface. Additionally, cleaning might be a bit more challenging compared to Teflon-coated models. As with any kitchen appliance, the choice between Teflon and stainless steel air fryers depends on individual preferences and needs.
