Is non stick pan harmful for babies, and is non stick pan harmful to the human body?

The advent of "non-stick pan" has brought great convenience to people's lives, people no longer have to worry about cooking meat will burn carelessly, and the fish fillets stick to the wall of the pan when frying fish. This non-stick pan has nothing to do with the appearance of a regular pan, except that an extra layer of PTFE is applied to the inner surface of the pan.

So is nonstick pan coating toxic? Is it harmful to humans? Here is a detailed talk for you, I hope it will help you!

Is nonstick pan coating toxic.

The main raw material for non-stick pan coating is PTFE. According to the national mandatory standards, PTFE is used as the main raw material, with certain additives to form PTFE coatings, coated on aluminum, iron plates and other metal surfaces, sintered at high temperatures, as anti-stick coatings in contact with non-acidic food containers, and the use temperature is limited to less than 250. PTFE can withstand high temperatures of 400 degrees, but chemical properties above 200 degrees.

It began to become unstable, and immediately burned at more than 400 degrees Celsius, releasing hydrogen fluoride.

The solution of gas, hydrogen fluoride dissolved in water is called hydrofluoric acid.

It is not only highly corrosive (a large amount of hydrofluoric acid is used in the glass etching process), but also highly toxic.

The current non-stick pan, no matter what form it takes, no matter which country it comes from, its main material is Teflon.

Infused with antioxidants.

and stabilizers to improve the high temperature resistance of PTFE. In short, no matter what name they are called, what substance they say, their main ingredient is PTFE. Although the maximum temperature does not exceed 180 degrees Celsius during cooking, the Teflon coating will always decompose little by little when heated by friction.

A non-stick pan with a long lifespan must not be used for frying or grilling pizza. In this case, the loss of PTFE can be minimized, and the harm to the human body is minimal.

If you buy a non-stick pan, don't use it for frying, frying and grilling, after all, accelerating the volatilization of Teflon materials is not good for health. From a health point of view: non-stick pans are not as healthy as iron pans.

It can be used, as long as the non-stick pan coating does not fall off, but the baby's diet is still based on breastfeeding, as well as breast milk with rice flour or milk powder. Individual.

From the field of science, the reason why the non-stick pan has this function is mainly due to the fact that there is a layer of coating on the non-stick pan, which can perfectly separate the food from the pan and achieve the effect of the non-stick pan, then this coating is toxic, but it should be noted that only this layer of coating is heated to a certain temperature and begins to melt toxinsThat is to say, only the processing of this coating will have the risk of poisoning, but this is not something we should worry about, because when processing this coating, the staff will wear protective tools, so if you want to use non-stick pans safely in daily life, you need to pay attention to the following points:

1. Don't boil the pot empty

We also mentioned above that this layer of coating will only decompose toxins after reheating to a certain temperature, so as long as we do not empty the pot, this will not happen, so when we use non-stick pans to cook in our daily life, we must pay attention to one point is not to let the pot boil empty, that is, there must be something in the pot.

2. Try not to use a shovel

In addition, when stir-frying, we try not to use a shovel, because the shovel is likely to shovel down this layer of coating, which will not only make the non-stick pan lose the role of the non-stick pan, but also may shovel down the toxic coating and mix it into the dish, which may cause certain harm to our human body, so when we use the non-stick pan, we must also pay attention and try to use a wooden spatula.

3. Do not use steel wool balls to brush the pot

Although the effect of steel wool ball brushing is very obvious, and it is particularly clean, but when using non-stick pans, I recommend that you try not to use steel wool balls to brush the pan, this principle is the same as not using a spatula, although the steel wool ball is more efficient, but it will also damage the coating of the non-stick pan to varying degrees.

Qualified coated pans are safe for the human body and will not cause harm to the body.

In the current non-stick pan market, PTFE is the most material. PTFE has strong stability, is not easy to react, has high acid and alkali corrosion resistance, and is not easy to produce harmful substances.

However, there are some precautions when using a coated pan. First of all, avoid overheating the non-stick pan, once the temperature reaches more than 260, the properties of the non-stick pan coating may be unstable, leading to decomposition. Therefore, it is recommended to cook at a low temperature, and the oil temperature should not exceed 70% hot.

Secondly, after using the non-stick pan, do not use steel wool to clean when cleaning, and wipe it with a soft rag. This effectively avoids damage to the coating. In addition, avoid using iron or other metal spatulas during the cooking process, as this will also prevent the coating from being scratched.

It's good, it saves the trouble of subsequent cleaning caused by the sticky pan.

Non-stick pans also have an advantage when making a sticky food. So as long as you use this pot correctly, it's still very good.

A non-stick pan is a pan that does not stick to the bottom of the pan for cooking, because the bottom of the pan is coated with a non-stick coating, and the common ones with the best non-stick performance are Teflon coating and ceramic coating.

Nowadays, in order to avoid the trouble of cooking rice and stir-frying, families like to use non-stick pans. After having a baby, many families will use a non-stick pan to cook for their babies because they are busy at work or for other reasons. So, is it OK for babies to use nonstick pans?

The ingredients of a non-stick pan are complex, and it is best not to use a non-stick pan to cook for your baby, so as not to affect your baby's health. The surface of the non-stick pan has a layer of anti-compression film that is specially processed using chemical ingredients to prevent food from sticking to the bottom of the pan. There are many organic compounds, some heavy metal elements or organic Gaoling Hu roll molecular compounds may be harmful to the baby.

Therefore, for the sake of safety, it is best for families with small babies not to use non-stick pans, but can use iron pots, which can also play a proper role in iron supplementation. It's non-stick, it's in the bottom of the pot with a layer of paint called "Teflon". This substance is a general term for fluoropolymers, including polytetrafluoroethylene, polyperfluoroethylene propylene and various fluorine-containing copolymers, these compounds have the advantages of high temperature resistance, low temperature, self-lubrication, chemical stability, etc., so they are widely used in non-stick cookware, waterproof and breathable materials (such as waterproof clothing), leather, automobile parts, and microwave popcorn bags.

Many of the foods we eat daily are acidic foods, including various meats, eggs, sugar, rice, etc. Acidic substances are easy to decay and corrode the metal body, and once the body is corroded, it will expand, thereby expanding the non-stick pan coating, resulting in a large area of the non-stick pan coating falling off.

Non-stick pans are healthy.

The surface of the bottom of the non-stick pan has a layer of special coating PTFE, also known as Teflon, which is a general term for a fluorinated resin substance. Including PTFE, polyperfluoroethylene propylene and various fluorinated copolymers. This kind of compound has the advantages of high temperature resistance, low temperature resistance, chemical stability, self-lubrication, etc., and is widely used in non-stick tableware, waterproof and breathable materials, etc.

Non-stick pans do not change in the temperature range of 260 °C, releasing unhealthy chemicals when the temperature exceeds 260 °C or above, and will not decompose when the temperature is up to 350° or above. The temperature of ordinary stir-fry is usually around 150, which is far from the temperature released by PTFE. Therefore, it will not be too much of a problem to use a non-stick pan for stir-frying in daily life.

Guidelines for the use of non-stick pans.

At present, most of the non-stick pans of socks will inevitably fall off or be scratched after a long time. Some experts said that under normal use, the properties of Teflon are very stable, and even if a small amount of peeling coating particles are ingested, they will generally be excreted by the human body, so it will not be seriously affected.

After the coating of the non-stick pan is dropped, there is indeed a certain health risk, the food is easy to adhere to, become charred, not only difficult to clean, but also easy to produce more harmful substances. Such as polycyclic aromatic hydrocarbons, etc. So for the sake of life, when I found that the non-stick pan coating at home had fallen off, causing the food to burn and paste, I still changed it.

Non-stick pan coatings of substandard quality can be harmful to health. Chromium is an essential trace element for the human body, but this heavy metal is counterproductive if it is exceeded in the body.

In addition, the fluorine-containing copolymer in the Teflon coating will be dissolved by fluorine when it is boiled and left in water, and if there is too much fluorine, it will have a series of adverse effects on the human nervous system, digestive system, urinary system, endocrine, etc.

In the monitoring of the materials laboratory of the Suzhou Institute of Product Quality Supervision and Inspection, the staff used potassium permanganate to test the soluble organic matter of the non-stick pan, which can be harmful to health if absorbed by humans. Monitoring found that more than 10% of non-stick pans consumed potassium permanganate.
