The staff of the domestic electrical appliance testing center of China Household Electrical Appliances Research Institute pointed out that normal use If the coating generally does not decompose, but once the temperature of this material exceeds 250 degrees Celsius, it may produce toxic substances.

Are rice cooker coatings really harmful? CCTV has done experiments and put Teflon in two different environments of 260 degrees and 350 degrees. The study found that Teflon did not change at 260 degrees, and it was slightly lighter at 350 degrees. Because our usual cooking temperature can not reach To 260 degrees or 350 degrees, so there is no need to worry about harm, but you must buy regular rice cooker products.
