However, the coating on the surface of the inner container will inevitably fall off after the rice cooker is used for a long time. Many health experts believe that the coating falling off after long-term use of rice cookers may even increase the risk of cancer. This also makes many friends feel suspicious.
In fact, the coating of rice cooker liner is similar to that of non-stick pan. The metal liner is covered with non-toxic spraying material, which prolongs the service life and avoids the problem of food sticking to the pot.
When the rice cooker is used for a long time, this protective layer will fall off due to long-term scrubbing and food corrosion. However, as mentioned above, this coating is non-toxic, just like the spraying material in a non-stick pan. Even if you fall off and eat by mistake, it will not affect your health.
Not only that, CCTV Life Circle program and beijing university of chemical technology have also done verification research on the health of the coating, and the results show that the main component of the coating is PTFE. Through the decomposition test of thermogravimetric analyzer, it is found that the decomposition temperature of Teflon is above 300 degrees, while the cooking temperature of rice cooker is about 180 degrees, so the coating will not release substances harmful to our health.
Therefore, the rice cooker is not a "harmful cooker", and the coating that falls off after a long time will not affect health, let alone cause cancer.
Hearing this, many friends may also be very happy: does this mean that rice cookers that have been used for a long time can continue to be used? In fact, rice cookers have been used for a long time, but there are some other health risks.
Although the peeling coating will not cause too much health hazard after long-term use of the rice cooker, the exposed materials after peeling off the coating may indeed bring health hazards.
This layer is made of aluminum. After the coating falls off, aluminum will be oxidized in the cooking environment, and alumina will directly contact with food during cooking, resulting in aluminum residue in food. However, aluminum is not a metal element needed by human body. Long-term intake of aluminum will lead to its continuous accumulation in human body, which will lead to memory loss and even increase the hidden dangers of nervous system diseases such as Alzheimer's disease.
It can be seen that although the coating of the rice cooker is harmless to the body, the aluminum exposed after the coating falls off may be harmful to health. Therefore, it is recommended that you use the rice cooker for a long time and replace it as soon as possible when the coating falls off seriously.
But then again, the coating of the inner container of the rice cooker can last for a long time, so the rice cooker will be more durable. Unless some unrequited measures are taken to prolong the life of the rice cooker as much as possible during the use of the rice cooker, these mistakes should be avoided as far as possible.
① Brush the inner container of the rice cooker with steel balls.
After cooking, if the rice cooker is left for too long, the rice will stick to the liner. At this time, forced flushing with steel balls will also stimulate the coating of the liner and make it fall off faster.
Therefore, it is recommended to use a mild rag or sponge when cleaning the inner container of the rice cooker. If the stain is too stubborn, you can also soak it in water in advance, and it will be much easier to clean up after a while.
(2) Add a lot of seasoning into the rice cooker.
Such as soy sauce, vinegar and rice wine. When it comes into contact with the inner liner of the rice cooker, it will also corrode the coating and reduce its service life. When cooking with an electric cooker, it is best not to put too much seasoning, and wash it in time after use to keep the inner wall of the coating as much as possible.
(3) Wash the liner immediately after cooking.
Just after cooking, the temperature of the inner container of the rice cooker is often higher. If you wash it immediately, the coating will fall off more easily because of the deformation of the inner wall in the case of alternating hot and cold, which is naturally not conducive to the maintenance of the rice cooker.
Therefore, before cleaning the inner container of the rice cooker, be sure to wait for the inner container to completely cool down, and remember to dry the water marks after washing, so as not to increase the corrosion degree of the rice cooker.
In short, although the rice cooker is a must-have item for every household, we also need to care for it patiently and meticulously, maintain it and use it healthily in order to eat safely. The maximum service life of an ordinary rice cooker liner is between 3 and 5 years. If the coating falls off in a large area, it should be replaced in time.
