A Comprehensive Guide To Non-Stick Cookware
Teflon, a non-stick coating brand owned by the company DuPont has become synonymous with non-stick coatings on cookware. However, not all non-stick coatings are Teflon and if you are wondering or not sure about the coating on your cookware, this guide will help you figure it out.
Non-stick coatings for cookware are typically flouropolymer plastic (PTFE) based or silicone based. Pots and pans are usually coated with PTFE coatings, while Silicone based coatings are mainly used in kitchen utensils and bakeware.
With the recent publicity about the safety of PTFE based non-stick cookware, there has been a spate of Ceramic based non-stick cookware on the market (also called ‘healthy cookware’ because ceramics are free of PTFE and PFOA).
Firstly, what is Teflon, PTFE and PFOA?
Teflon is the brand name for a plastic product called polytetrafluoroethylene (PTFE).
PFOA (Perfluorooctanoic Acid) is another chemical that is used in the process of making PTFE. It is NOT the same as PTFE.
PFOA is burned off during the process and no significant amount remains in the final product. Previously, all nonstick coating manufacturers used PFOA in the manufacture of nonstick. However, PFOA is considered a pollutant and a toxic substance and now, under the stewardship of the Environmental Protection Agency, most of the reputable non-stick coating manufacturers are producing coatings made without PFOA. This includes Teflon.
So when you see a cookware advertising ‘PFOA’ free, it usually means the PTFE was made without the use of the chemical PFOA in the manufacturing process. [Tweet This!]
Is PTFE/Teflon safe?
Ordinarily, Teflon is an inert substance and even if a piece of nonstick flakes off and ends up inside you, it will simply pass through your system. You might be interested to know that because of its non reactive nature, Teflon is even used in joint replacements!
Only when it is heated to a high temperature like 500 degree F does Teflon start to deteriorate and release fumes which have been found harmful for birds and cause flu like symptoms in humans.
In ordinary use, pans are not usually heated to such a high temperature. So in a nutshell, yes, Teflon or PTFE is safe as long as you are diligent about not heating an empty pan or cooking on too high a temperature.
The objective here is not to take a stance for or against PTFE or Teflon. It is to provide information so you know what you are getting and can see through the marketing clutter of different manufacturers.
So in most cases:
- Unless it specifies ceramic or silicon based non-stick, non-stick cookware contains some form of PTFE or related plastic compound.
- When they say ‘it’s not Teflon’, they are right. Teflon is a brand name. But in most cases it will contain some form of PTFE. Yes, even Swiss Diamond.
- And when they say PFOA free, it means that particular chemical wasn’t used in the manufacture of PTFE. But it’s still PTFE.
If PTFE is a concern for you, there are several ceramic options available (see below). Keep in mind that ceramic based non-stick coatings have been found to be much less durable than plastic based coatings.
