Our country is vast and rich in resources. Due to the different geographical location and environment in the north and south, crops are planted differently. We grow wheat, and rice is grown, so we have developed different eating habits for people from the north and south. Northern Northern People like to eat steamed buns, while southerners like to eat rice.
However, nowadays, communication between the north and the south is getting closer, and our tastes are gradually becoming more similar, so more people eat rice in daily life. Rice is relatively more convenient to make. Now almost every household has rice cookers, and some rice cookers can also make appointments, so that only rice and water are needed, and then wait for the delicious rice.
Rice cooker has many functions in addition to making rice, such as baked cake , rice cooker steamed pork, rice cooker hot and sour noodles, etc. As the saying goes, "People are popular and there are many troubles." Just when merchants are vigorously promoting rice cookers, another sound appears on the Internet. Rice cookers cannot be used. Frequent use of rice cookers will cause cancer. Will eating rice cookers often cause liver cancer ? Once the statement of
appeared, it attracted the attention of many netizens and even caused panic among netizens. So is there any scientific basis for this statement? CCTV specially made experimental evidence!
WHO calls for: Will stop using rice cookers cause liver cancer? CCTV experiments explain the truth
The reason why rice cookers are said to be cancerous on the Internet is mainly because of the inner liner of the rice cooker. Many people think that the inner liner of the rice cooker is toxic, and long-term use of this cooking utensil will cause cancer.
Aluminum rice cooker inner liner is the first choice because aluminum heats more uniformly and heat transfer speeds are faster. However, in addition to aluminum inner liner, there are also stainless steel inner liner on the market, and ceramic inner liner has also emerged in recent years.
No matter what material it is, in order to isolate the material from food, a protective layer will be applied on the inside of the rice cooker. Netizens believe that the rice cooker can cause cancer because of the existence of this protective layer.
Because the material of this coating is usually Teflon, Teflon has the functions of blocking and anti-sticking, and is stable in nature and not easy to decompose. However, many people believe that Teflon will emit toxic substances during the heating process.
For this reason, CCTV's "CCTV Life Tips" conducted an experiment on the rice cooker. Professor Xiong Jinping found a commonly used rice cooker, then took out the inner liner coating, analyzed it through professional equipment, and after an hour of observation, it was finally found that Teflon would only decompose in an environment with a temperature of up to 300℃ or above.
When we use rice cookers normally, the general temperature is around 180℃, so the coating cannot be reached at all. The decomposition temperature will naturally not lead to the decomposition of the coating, and the statement that cancer is self-defeating.
Then Professor Xu Lianping conducted experiments on the ordinary rice cooker used in our family and found that the normal working temperature of the rice cooker can only be maintained at around 103 degrees Celsius, and the temperature during normal insulation is only 60~70℃. Even after high-pressure water boils, the temperature at the base is only 150~170℃.
From this point of view, the rice cooker we usually use generally does not exceed 180℃, and it is impossible to decompose Teflon, so everyone can use it with confidence and boldness.
4 situations will cause the coating of the rice cooker to be damaged
1. Use steel wiping balls to clean
If the steel wiping balls repeatedly rub against the inner liner of the rice cooker, it is easy to cause the coating to fall off. The coating may fall off a little at the beginning, but the area of the coating will fall off later. If such a rice cooker continues to be used, it will easily lead to toxicity, which is not conducive to health.
So when you use a rice cooker, you only need to clean it with a sponge or a soft cloth. Don’t use a steel wool ball. If it becomes sticky, you can soak it in clean water for a while.
2. Use a metal shovel to serve rice
. Don’t use a metal shovel when serving rice. It is best to use a wooden or heat-resistant silicone shovel, because the metal shovel can easily scratch the inner liner of the rice cooker, especially when scooping rice too hard, it is easy to cause damage.
3. Rinse immediately with cold water after serving the rice
If the rice cooker has a certain temperature, do not rinse with cold water immediately, otherwise the alternation of cold and heat will easily cause the coating to deform, and it will accelerate the coating to fall off. Be sure to completely cool the rice cooker before washing with cold water.
4. Do not cook acidic foods
It is not recommended to use rice cookers to cook acidic foods such as hot and sour soup, because acidic foods may enter the pores of the inner liner to corrode the substrate material of the coating, causing the coating to fall off, which will reduce the service life of the rice cooker.
Even if the rice cooker is not damaged, if it is used at a high frequency, it is best to replace the inner liner every 3 to 5 years apart.
