WHO urges to stop using rice cookers, toxic and cancerous? CCTV experiment revealed the answer
There is an article saying, "WHO calls: stop using rice cookers, or catalysts for liver disease and liver cancer", and there are also claims that often used rice cookers contain coated Teflon, which may be a liver cancer catalyst. Can people still use it? Is that rice cooker really toxic and carcinogenic? What are the facts?
1. Are rice cookers toxic and carcinogenic?
In fact, the rice cookers we use on the market generally use aluminum inner pots . Metal aluminum itself is heated more evenly and heat transfer is faster. However, in order to prevent aluminum from being heated and subjected to acid corrosion and precipitating into food, aluminum is generally used. The combination of the inner pot + coating is used to make the inner pot of the rice cooker.
The coating in "aluminum liner + coating" generally refers to perfluorinated polymers such as polytetrafluoroethylene, that is, Teflon . The staff of the Living Appliance Testing Center of China Household Electrical Appliances Research Institute pointed out that normal use 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: 260 degrees and 350 degrees. The study found that Teflon did not change at 260 degrees, and it was slightly lighter at 350 degrees. To 260 degrees or 350 degrees, so there is no need to worry about harm, but be sure to buy regular rice cooker products.
2. The rice cooker is scratched, can it still be used?
If you find that the rice cooker is scratched during use, and small black or white areas appear, it means that the coating of the inner pot has fallen off a lot. It is best to stop using it immediately and buy a new rice cooker. If the inner pot is made of aluminum Direct contact with food may lead to the precipitation of aluminum elements, resulting in excessive aluminum intake in the body, resulting in a certain health threat.

During the use of the rice cooker, if you need to use a rice spoon or rice shovel, it is recommended to use wood or hot silicone material to avoid damaging the coating, and to avoid emptying or placing food for a long time.
3. After use
After the rice cooker is used, it should be cleaned in time. Do not use steel balls and other hard things to clean it. Use a soft cloth when cleaning, otherwise the coating may be damaged, and even affect the normal use of the rice cooker.
There are rumors that the coating of the rice cooker is toxic and can cause cancer, but in fact, the general cooking will not cause the coating to decompose, but it should be noted that once the rice cooker is scratched, do not use it, and it is best to replace it with a new one. Usually, we must pay attention to the safe use of rice cookers, do a good job in daily cleaning and maintenance, and try to extend the service life of household rice cookers.
