The coating of the non-stick cooker liner of rice cooker falls off in a large area, so it should be replaced with a new liner or eliminated immediately, because after the coating falls off, the liner is more likely to emit toxic gas at a lower temperature. The main component of the coating is polytetrafluoroethylene, also known as "Teflon". The purpose is to prevent food from sticking to the pot, which is more corrosion-resistant.
However, PTFE contains ammonium perfluorooctanoate, which is a chemical substance. If the non-stick pan is in good condition, it is no problem to use. Once the coated surface of the pot is scratched or damaged, it is best to replace it immediately. At this time, ammonium perfluorooctanoate may penetrate into food, causing cancer risk.
Extended data
Usually clean the rice cooker with bamboo, wooden shovel and soft cloth, and leave it for a while after cooking. Don't rinse with cold water immediately. Do not boil acid, alkali or salty substances, and do not put them in damp places to prevent corrosion. Someone should be present when cooking soup and stew with rice cooker to prevent water from overflowing into the electric appliance and damaging the electric heating element.
The bottom of the pot should avoid collision and deformation. The space between the heating plate and the inner pot must be kept clean to avoid affecting the thermal efficiency and even damaging the heating plate. The inner pot can be washed with water, but the outer shell and the heating plate can't be soaked in water, and can only be wiped clean with a wet cloth after the power supply is cut off. It is not suitable for cooking acid and alkali foods, and it is not suitable for being placed in corrosive gas or humid places.
When using the rice cooker, the heating temperature should not exceed 100 degrees. The inner container of the rice cooker should be handled with care, and it is best not to be bumped by hard objects, otherwise it will be deformed, and the heating device will not fit the inner container, resulting in uneven heating of the rice contained in the inner container and uncooked rice.
Phoenix Information-Don't use it if the coating on the inner liner of the rice cooker falls off!
