Using a Teflon-coated pan on an induction cooktop generally does not pose any significant risks or interference. Induction cooktops generate heat by creating an electromagnetic field, which induces a current in the cookware, causing it to heat up. Teflon, also known as polytetrafluoroethylene (PTFE), is a nonstick coating that is not affected by induction heating.
However, it's essential to note that there are a few considerations when using Teflon-coated pans on any type of stovetop, including induction:
Temperature limits: Teflon coatings have temperature limits, typically around 500°F (260°C) or lower. Exceeding these limits can cause the coating to degrade, releasing potentially harmful fumes. While induction cooktops can quickly heat up pans, it is essential to monitor the temperature and avoid overheating the Teflon-coated pan.
Scratches and wear: Teflon coatings can be susceptible to scratches from metal utensils, which can reduce their effectiveness and potentially expose the underlying metal. It's advisable to use non-metallic utensils, such as wood, silicone, or plastic, to prevent damaging the coating.
Health concerns: Overheating or overheated Teflon coatings can release fumes that may be harmful if inhaled. These fumes are typically produced at temperatures well above normal cooking temperatures and are known to cause polymer fume fever, also called Teflon flu, which can lead to flu-like symptoms. It's important to use Teflon-coated pans within their temperature limits and provide proper ventilation in the kitchen.
While Teflon-coated pans are generally considered safe for use on induction cooktops, it's crucial to follow the manufacturer's instructions and take precautions to avoid overheating or damaging the coating. If the Teflon coating becomes scratched, worn, or damaged, it's advisable to replace the pan to ensure safe and effective cooking.
