Voici pourquoi vous devriez prêter plus attention à l'état de vos poêles anti-adhésives

According to a new study, non-stick pots and pans with damaged surfaces can release millions of plastic particles during cooking. According to the researchers, simple cracks are enough to cause the release of microplastics.

Non-stick pots and pans release thousands of plastic particles

According to a new study published in Science of The Total Environment, Teflon (used in the design of non-stick pots and pans) could be releasing thousands of plastic particles.

To reach this conclusion, the researchers measured the quantity of microplastics and nanoplastics released by non-stick pots and pans using Raman spectroscopy, a technique for analyzing molecular structure.

At the same time, they also used algorithms to calculate the amount of plastic likely to come loose and end up in our food, and simulated a cooking process.

Up to 2.3 million particles released

According to the results, a damaged non-stick pan or saucepan can release 2,300,000 microplastics and nanoplastics. A single surface crack, meanwhile, can release around 9,100 plastic particles during a cooking process.

According to one of the study’s authors, Cheng Fang, a materials scientist at the University of Newcastle in Australia:  » Given that per- and polyfluoroalkyl substances (PFAS) are a major concern, these Teflon microparticles in our food could be a health issue » .

While more research needs to be carried out, the researchers recommend that all users throw away their damaged and broken non-stick pots and pans to avoid the slightest health risk.

They also remind us to avoid using sharp utensils to preserve non-stick coatings and prevent the release of plastic particles.
