Fry pans with nanocoatings: Do nanoparticles come off during frying?

Question: “Do particles pass over into the food? Will this cause health hazards?”

As a rule, cookware non-stick coatings have nothing to do with the nanoparticles discussed hereunder but consist of very heat-resistant polymers applied in layers. The effect of the surfaces obtained that way is similar to the well-known roll-off effect of the lotus plant.

Since manufacturers mostly make a mystery (patent) out of these kinds of coatings, there is no exact information about their possible hazards. However, since only „safe consumer products“ are allowed on the market, the non-stick coatings are assumed to be safe as well.
