Just like the apron of rice cookers and pressure cookers, because the boiling point of water is about 100℃, this silica gel will not produce harmful substances. As long as you buy qualified products, don't worry about it. Moreover, all health pots have the function of preventing dry burning, and will automatically cut off power when there is no water.
Why does the health pot smell? The plastic smell of inferior health pot after boiling water is very heavy, because the apron used to seal the heating plate is made of non-food grade ordinary silica gel. When the upper part of the apron comes into contact with water and is heated and decomposed by the heating plate, it will continuously release odor and harmful substances, which is harmful to human health. Regular health pots are non-toxic and tasteless, and most of them use imported food-grade silicone rings.
