What is nonstick cookware and how does it work?
Nonstick cookware is a type of cookware that features a coating that prevents food from sticking to it. This coating is usually made from a synthetic polymer called polytetrafluoroethylene (PTFE), also known as Teflon. When heated, the PTFE coating creates a non-stick surface that allows food to slide off easily, making cooking and cleaning a breeze. Nonstick cookware has become incredibly popular in recent years due to its convenience and ease of use. It is available in a wide range of products, including frying pans, saucepans, skillets, and baking dishes.
The nonstick coating works by creating a thin, impermeable layer on the surface of the cookware. When food is cooked, it does not come into contact with the metal surface of the cookware, but instead interacts with the nonstick coating. This prevents food from sticking and makes it easy to flip and remove food from the cookware. However, the nonstick coating can wear off over time, especially if the cookware is used at high temperatures or with metal utensils. When the coating wears off, the cookware may need to be replaced.
