If the bottom of your Teflon-coated pan is getting burnt when using high heat, it is likely due to the limitations of Teflon as a non-stick coating and the way it responds to high temperatures. Teflon, also known as polytetrafluoroethylene (PTFE), is a synthetic fluoropolymer that has excellent non-stick properties. However, it does have some temperature limitations:
Temperature sensitivity: Teflon starts to degrade and release toxic fumes, including perfluorooctanoic acid (PFOA), when exposed to high temperatures above 500°F (260°C). While most cooking doesn't typically reach these extreme temperatures, it is possible to reach temperatures high enough to damage the Teflon coating.
Thin coating: Teflon coatings on pans are generally thin, and prolonged exposure to high heat can lead to the breakdown of the coating, causing it to lose its non-stick properties.
Uneven heat distribution: High heat can cause uneven distribution of heat on the pan's surface, leading to localized hot spots that can burn food or the Teflon coating itself.
To prevent burning and extend the life of your Teflon-coated pan, it's best to use low to medium heat for most cooking tasks. This will help prevent overheating and ensure more even heat distribution across the pan's surface.
Here are some tips to care for your Teflon-coated pan:
Use low to medium heat: As mentioned before, avoid using high heat and opt for lower temperatures when cooking with your Teflon pan.
Preheat with care: Preheat the pan slowly over low to medium heat. Avoid preheating an empty pan for an extended period, as this can lead to overheating.
Use the right utensils: Use silicone, plastic, or wooden utensils to prevent scratching the Teflon coating, which can accelerate its degradation.
Hand wash: While some Teflon-coated pans are labeled as dishwasher-safe, hand washing is generally gentler on the coating and can help prolong its lifespan.
Avoid metal scouring pads: Abrasive materials like metal scouring pads can damage the Teflon coating, so stick to soft sponges or brushes for cleaning.
Replace damaged pans: If you notice the Teflon coating peeling, flaking, or showing signs of significant wear, it's time to replace the pan for safety and cooking performance reasons.
Keep in mind that Teflon-coated pans do have a limited lifespan, and the coating will eventually wear out with regular use, even when properly cared for. When replacing your pan, consider investing in higher-quality cookware that may have more durable non-stick coatings or explore alternative materials like ceramic, stainless steel, or cast iron pans for high-heat cooking methods.
