WHO calls to stop using rice cookers? Do rice cookers cause cancer? CCTV experiment tells you the answer
Previously, there were rumors on the Internet that a couple were both targeted by cancer, which was related to the use of rice cookers, and that the WHO called on rice cookers to cause cancer and should stop using them as soon as possible.
Once such news was released, it attracted widespread attention from many netizens. Could rice cookers really cause cancer?
1. Can the liner of the rice cooker cause cancer?
The more common rice cooker inner pots include aluminum inner pots, stainless steel inner pots, and ceramic inner pots. Of course, the most commonly used aluminum liner is the aluminum liner , but since the aluminum liner cannot directly contact the food, the merchant will make a coating on the outside of the inner liner, which can also prevent sticking.
Common rice cooker liner is composed of aluminum liner + coating, and the coating generally uses perfluorinated polymer (Teflon) , which is more resistant to acid and alkali, and is not easy to decompose, so if the coating is not Falling off, the use of the rice cooker will not cause harm to the human body, or cause cancer.
A CCTV program "Life Tips" once conducted a related experiment. In the Teflon was heated at high temperature until it was decomposed at about 300 degrees, and the higher the temperature, the more toxic the decomposed product. In fact , the temperature that the rice cooker can reach is only about 100 degrees, and there is no need to worry about reaching the temperature that Teflon decomposes , so there is no need to worry that the rice cooker will induce liver cancer.
2. The coating peels off, can the cooked rice still be eaten?
After the rice cooker has been used for a long time, it is very likely that the coating will wear out or even fall off. From the beginning, it will gradually fall off more. Can the rice cooked at this time still be eaten?
"National Food Safety Standard for Food Contact Coatings and Coatings" points out that the total migration of the inner liner coating of the rice cooker should not exceed 10mg per square decimeter, otherwise it may affect the health of the body. After the coating of the rice cooker falls off, the total migration amount may exceed the standard. Therefore, if you find that the coating falls off a lot, do not use it to cook rice , and replace it with a new rice cooker in time!
