Is the coating of the inner liner of the rice cooker toxic
At present, the inner coating of rice cookers in my country is mostly made of Teflon, which is a fluorine-containing polymer. This material is the same as that of non-stick pans, and it will decompose harmful substances to the human body at high temperatures above 250 degrees. However, since the temperature of the rice cooker generally does not exceed 100 degrees, the cooking process is relatively safe.
However, experts pointed out that this material is susceptible to corrosion by acidic substances such as rice and meat, and once it is corroded, the coating will fall off. If this coating is eaten into the body, it cannot be decomposed, and it is not easy to excrete, and it can even cause cancer if it stays in the body for a long time. Experts remind the public that once they find that the coating of the rice cooker at home is peeling off, they should stop using it.
Can the rice cooker still be used if the coating is removed?
At present, my country does not clearly stipulate what the inner coating of the rice cooker must be used for. The same kind of raw materials, but generally better quality pans are made of Teflon, which is a non-stick pan. Then let’s take a look at this kind of rice cooker with Teflon inner coating, what kind of characteristics it has.
Because the rice cooker is different from other cooking pots, it has a computer control device. When the temperature reaches a certain temperature, the rice cooker will automatically trip and will not continue to heat. Moreover, the rice cooker is used in the state of water and rice. With these two media, plus the function of the rice cooker itself, the temperature of its inner coating will generally not exceed 100 degrees. In this case, if the inner coating of the rice cooker is not artificially damaged by external force, its service life will be longer, and basically there is no major problem within 10 years. However, experts also said that the inner coating of the rice cooker will gradually fall off after long-term use, so this shedding material will inevitably be eaten by people, so will it cause any harm to the human body? Woolen cloth? Since Teflon material is an inert substance, if it is not under the action of high temperature above 260 degrees, it will not cause harm to the human body, and the operating temperature of the rice cooker is impossible to reach 260 degrees, so everyone You can use the rice cooker with confidence.
What is the healthiest material for the inner liner
Rice cookers (pots) have now become a must-have kitchen appliance for families. The price varies from thousands of yuan, and the quality varies. How to choose a rice cooker? At this time, we must keep in mind that the inner pot is the “heart” of the rice cooker, and the quality of the inner pot directly determines the quality and life of the rice cooker.
Nowadays, the most common rice cooker on the market is the use of general aluminum alloy inner pot. The thickness of this inner pot is generally less than 1.2 mm, and the surface treatment technology mostly adopts ordinary non-stick coating. This kind of liner is generally very effective at the beginning, without crockpot, and will not stick to the pan, but after a long-term high temperature action, it is easy to deform, and the non-stick coating on the surface is easy to fall off after brushing, more Seriously, these peeled coatings and the exposed aluminum layer after the coatings are peeled off are easily mixed into food and have adverse effects on the human body.
Another more common type is the rice cooker made of stainless steel, which is more expensive than the one made of alloy aluminum. Stainless steel rice cookers don’t have to worry about the peeling off of the non-stick coating, but cleaning the stainless steel inner pot is really troublesome, and it is often difficult to remove the rice cooker left after cooking.
In view of the defects of the above two kinds of inner pots, some big brand manufacturers have started research and launched rice cookers with black crystal inner pots, using alloy aluminum with a thickness of 2 mm, and using The oxidation process of aerospace technology not only makes the strength higher, but also greatly improves the wear resistance and non-stickiness; there are also rice cookers with ceramic crystal inner pots, and the mature ceramic technology is applied to the inner pot of the rice cooker, so that the traditional chemical surface treatment The process turns to “natural” surface treatment, this pure natural inorganic substance completely avoids the secondary pollution of paint and metal liner for a long time during the cooking process. When many consumers buy new rice cookers, they tend to prefer this kind of rice cooker with new technology.
If you are financially well off, and you are more concerned about food quality and quality of life, rice cookers with ceramic and black crystal liner are good choices. And if you are very experienced in cooking, you will basically not leave the rice cooker on the inner pot after cooking, and you will be easier to use a rice cooker with a stainless steel inner pot. If your budget for this appliance is not too high, you might as well choose an economical rice cooker with an aluminum alloy liner.
Notes on using rice cooker:
1. Do not use rice cooker to cook foods that are too acidic or alkaline. Because the inner pot of the rice cooker is made of ceramic or aluminum, cooking too sour and salty food with it will cause the inner pot to be eroded and easily damaged. In addition, people should be guarded when cooking rice and stewing meat to prevent soup and other water from overflowing into the electrical appliance and damaging electrical components.
2. Don’t touch the rice cooker often. Because the inner pot of the rice cooker is easily deformed after being touched, the bottom of the rice cooker cannot fit well with the electric heating plate after the inner pot is deformed, resulting in uneven heating during cooking, and it is easy to cook raw rice. Therefore, it should be handled with care when using the rice cooker.
3. When using the rice cooker for the first time, it is best to boil a pot of boiling water first. After 5-7 minutes of boiling, the magnetic steel temperature limiter does not lose its magnetism and falls, which not only indicates that the rice cooker has normal performance, but also can clean the new pot.
4. When using the rice cooker, pay attention to good contact between the bottom of the pot and the heating plate, and turn the inner pot left and right several times.
5. After using the inner pot, the inner pot should be washed clean, and then put into the rice cooker after drying the outer surface.
