Is the non stick liner coating of rice cooker harmful to the human body

Of course it is harmful, stainless steel, non-stick pans, manganese, lead, copper metal, etc., you say that one is not harmful to the human body? No, it is recommended to use a pot of wrought iron, pig iron is not easy to clean, and wrought iron can be used to remove oil residue at high temperature.

The so-called non-stick pan was the initial generation of Teflon (plastic stuff) Now the question is not what pot you use, but whether you have a choice, some things that money can't buy, we don't have to choose!

It is recommended to use the imported EU standard or the standard of リベン, and there is no standard for cooking utensils in China!

Whether the liner coating is harmful to the human body or not is more complicated, and any statement that tells you that it is definitely harmful or definitely harmless is not responsible. The reasons are: on the one hand, there are different types of coatings, for example, Teflon is the most mature coating, which has relatively high safety; Other coatings are less mature and have a relatively low level of safety.

On the other hand, even the most mature Teflon has different test data on its safety, which is simply not necessarily absolutely safe. For detailed health theories and the health properties of different coatings, please refer to my blog post "How to make healthy choices about rice cookers, electric pressure cookers and their liners".

My advice to you is: try to choose a stainless steel liner.

2. The available information shows that PFOA is mainly a water source, not a cooker. Friends who still have concerns can choose not to use PFOA products, or liners made of other materials. 3. If the coating is scratched or peeled off, it is best to change the inner tank, because it is very likely that the problem of aluminum leaching of the pot body will occur.

The rice cooker is best made of stainless steel liner.

The inner tank of the electric pressure cooker is best made of stainless steel, which is safe and durable, and meets the requirements of health and hygiene. The only disadvantage is that the stainless steel electric pressure cooker liner has blind spots when heated, and it is easy to paste when cooking porridge.

The coated liner is non-stick and easy to clean, but it has weak resistance to metal spoons and steel wool balls, so be careful when using and cleaning. You can continue to use it even if the coating is off, but the composite coating liner is easier to absorb flavor, and the taste of the meat may remain a little bit after the meat is cleaned.

Common Rice Cooker Layer Materials:

The inner liner of the rice cooker is coated with a non-stick pan. At present, there are three main organic coatings widely used: polytetrafluoroethylene (PTFE), fluorinated ethylene propylene copolymer (FEP), and tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer (PFA). All of them have good non-stickiness, and they all meet food-grade standards, as long as they are used normally, they will not cause harm to the human body.

Given that the temperature of the rice cooker generally does not exceed 100 degrees, the coating is still relatively safe during the cooking process. However, this material is susceptible to corrosion by acidic substances such as rice and meat, and once corroded, the coating will fall off.

The coating is unsafe, preferably made of food-grade stainless steel 304, which is harmless to the human body.

Relatively speaking, the stainless steel liner is better.

In terms of health, the stainless steel liner is uncoated, so you don't have to worry about eating the coating.

Functionally, the stainless steel liner can cook a lot of things, cook rice, make soup or something.

In terms of durability, stainless steel liners are certainly much more durable than coated liners.

But the bad part is that the stainless steel liner is a little sticky to the pot, but the sticky point is generally acceptable, I just happen to be making the liner, if you need to find me. Hope it helps.

Coated ones are rubbish! It can be said that the person who invented this so-called "non-stick pan" coating is a complete waste!

The reality is that this coating ends up being eaten in its entirety! If there is this "material" in the human body, I don't know what kind of lesions or cancer will be produced! Hey, the Chinese are all test samples of some so-called "high-tech" products!

The coated ones are generally food-grade coatings, non-stick pans, and that thing is not harmful to the body, it just plays the role of a non-stick pan, I also asked when I bought the pot, and the brand of Kuchen that I use now is coated. It's OK.

Rice cookers with coating are the worst foreign countries don't use China, why are they being used. It's all a lie to say that it's okay.

The rice cooker liner will often be deformed because of the deformation of the bottom of the pot, resulting in the inability to fit closely with the heating plate and cause it to not work normally, starting from this point, the liner is not easy to deform as well, so there are stainless steel liners, aluminum liners and other different material products can be used, of course, the strength of the stainless steel liner of the same thickness is higher than that of aluminum products, and there is no suspicion of "causing more absorption of aluminum elements".

Aluminum alloy liner and aluminum liner are actually aluminum products, because the surface of the aluminum is easy to generate a dense oxide film to protect the inside from being oxidized, so they are "not easy to rust", but acid, alkali, etc. are easy to destroy the oxide film, pay attention to when using; In terms of processing performance, for parts such as processing liners, if aluminum is used with high purity, it is convenient to process, because the mechanical strength of general aluminum alloy is higher than that of pure aluminum, and it is not easy to deform (such as the "dura aluminum" used on the aircraft), so the same thick and thin aluminum liner, the strength of aluminum alloy is generally higher than that of pure aluminum, and it is not easy to deform, but for production, it is easier to process pure aluminum and can be made thinner, and then hanging on the "alloy" is more attractive;

In terms of use, although the thickness of the inner tank can not be measured when purchasing, and it is not possible to check whether it is alloyed, press the convex surface of the bottom with the heating plate with your fingers, and test it, always with the bottom is thick and not easy to deform.

The main function of the rice cooker coating is to be heated evenly to ensure that the food in the pot is heated evenly and to achieve the effect and effect of not sticking to the pot. The disadvantage of an uncoated rice cooker is that it sticks.

The liner coating of rice cookers is basically divided into two categories: one is water-based non-stick fluorocarbon coating, which is mainly provided by PTFE. The other type is ceramic coatings that have only emerged in recent years.

To distinguish between water-based fluorocarbon paint pot and ceramic coating, you can distinguish by looking at the color of the paint film, which is very smooth and has a high gloss of ceramic coating; It is soft and does not have a high gloss, and it is basically black and is water-based fluorocarbon.

At present, the inner coating of rice cookers in China is mostly made of Teflon, which is a fluorine-containing polymer. This material, like the material of non-stick pans, decomposes substances that are harmful to the human body at a high temperature of more than 250 degrees Celsius. However, given that the temperature of the rice cooker generally does not exceed 100 degrees, it is still relatively safe during the cooking process.

However, this material is susceptible to corrosion by acids such as rice and meat, and if it is corroded, the coating will peel off. This coating cannot be decomposed if eaten into the body, and it is not easy to excrete, and it can even cause cancer if it remains in the body for a long time. As soon as you notice that the coating of the rice cooker in your home is peeling off, you should stop using it.

Introduction: The coating of the rice cooker liner is generally tested for high temperature hardness, temperature resistance test, cold and thermal shock, acid and alkali resistance test, boiled brine test, boiled rice test, wear resistance test, etc., the most stringent is to cook rice, about 500 times, Soqing has seen a company, there are two people, and the daily work is to test the cooking rice, the taste of rice in the house. 500 times is equivalent to two years of use by the average family, and it is okay to use it for two years.

There are several kinds of rice cooker liners, honeycomb pots, non-stick coatings, hard oxide layers, aluminum alloy layers, and hard oxide layers. Among them, the flushing non-stick coating can ensure that cooking is not burnt, and nutrients are not wasted, and the double hard oxide layer is conducive to long-term safe use. Moreover, the thickness of its inner tank is more than 2mm, and the heat transfer is more uniform.

Super thick inner tank + four-layer structure", the nutrition of rice is guaranteed; Midea applied the aluminum oxidation technology on the surface of the space vehicle to the rice cooker liner and launched the "Space Aerospace" technology rice cooker; The inner liner of the Panasonic rice cooker is coated with advanced far-infrared thermally effective fluorine, which heats more evenly.

Midea is currently using Taiwan's Xier coating, said to be nano coating, you can search on the Internet, in Foshan Shunde Beijiao production, where is the Midea production base of household appliances, the outer wall of the inner tank also has a coating, generally black.

Supor's ceramic crystal liner began to use South Korea's Korean ceramic paint, similar to enamel, but now it seems to have been replaced by Xier's, in Hangzhou's high-tech park, it seems to be called Bin'an Road, Supor's inner tank is hard oxidized first, so it is better than the United States, I have not seen a coating on the outer wall of Supor.

Conclusion: From the perspective of the processing process of rice cooker liner spraying, the first is to mix various formula materials with fluorine coating concentrated emulsion to become a kind of paint with a relatively loose leakage ridge, spray the liner with paint, sinter once after spraying, and then spray after firing, and spray it many times to achieve the corresponding thickness.

Natural shedding may not be, basically caused by direct blunt injury of hard tools during use, hard metals such as stainless steel tools are not directly poked, after bumping and vibration, the high temperature will be spotted after a long time. It is recommended to use a wooden spoon and spatula, and use it with proper force and without being violent. Usually long enough.

I don't know much about the coating of rice cookers, but I know that when I buy a good rice cooker liner, the paint will not peel off and the pan will not stick much.

I now use a Philips rice cooker, the inner tank is made of aluminum-iron alloy, very thick, good quality, and very easy to clean, Philips' inner tank will not fall off easily, this has not happened until now.

Afraid of falling off the paint, everyone wants to find a stainless steel liner: 1However, the stainless steel liners on the market are not pure stainless steel, and there can be no pure stainless steel.

2.Take a look at the manufacturers of professional cooking pots that use non-stick liners. All of them are qualified food-grade non-stick materials.

3.The stainless steel liner is made of metal, and it is not good for metal precipitation in the body after long-term use.

There are a number of reasons why it drops:

1.It is easy to oxidize by dry burning or repeated heating; 2.Incorrect cleaning of the inner tank, in fact, is no longer non-sticky, why use a wire brush to wash it?

The protective film is gone, how to use it for a long time; 3.Some merchants use inferior materials to save costs. After long-term high-temperature oxidation, the paint will fall off.

Of course, the stainless steel liner! Stainless steel is alloy,!! The coating is still forgotten, it hurts.

Everybody has a cold, you need to catch a cold?

Dongdong, which is hundreds bigger, will not dare to use it anymore. Yesterday I went to buy a beautiful one. Let's use domestic products!
