I posted on 2023-4-13 that the current non-stick pan is seven times more poisonous than before. The online horror marketing was reported. After that, many readers left comments and discussions. Among them, what I think is worth sharing is a YouTube video Nonstick Pan Safety ANSWERS attached to ppo1764 on 2023-4-22. It is in English, but the subtitles can be translated into Chinese. Why is it more worth sharing? Because it is interesting that the owner of the film asked a toxicologist if he was using iron fluoron non-stick pot, and she smiled heartily and then made a professional explanation.
The latest message is Ken Hsu sent on 2024-1-2:
"I have only read the article so far. The professional responses are really impressive!! But in addition to utensils, Teflon is also used on the surface of various medical materials, mainly to prevent stickiness and slippage, such as heart tubes and replacement links, please ask Professor Lin. In this regard, research on the materials used should be directly in contact with humans, and long-term wear and contact with body fluids, which should be more risky than the tin. However, in life support, it is often used for the purpose of maintaining life. If the benefits are greater than the disadvantages, it can be used. Will this affect the choice of material? As for the Internet In terms of business, when selling, we naturally have to live dead people and bones, and give all the things with problems to pile up, and mix PTFE, PFAS, etc. The only discussions between true and false, we can only judge it by yourself. It turns out that ceramic matte utensils use silicon oxide (Siloxane) and Teflo. n is considered two common medical materials. As for who is good and bad, what is the relationship between ceramic mattresses and silicides? You can think of such a weird language, which makes people feel very safe. It is a good marketing right away! Teflon heard it and it dropped.This message involves two questions -(1) Medical application of iron fluoride, (2) Is ceramic matte pot safer? Regarding the first question, I have published iron fluoride two days ago to save your life. Today we will discuss the second topic.
Regarding the safety of ceramic matte utensils, the first thing I think of is the brand endorsed by the terrifying marketing network. I found the brand's patented mattress webpage, and it has such a statement: "XtremaTM is an upgraded version of ceramic mattress. It is made of ceramic raw material (silicon dioxide). The main ingredients are made of natural sand and stone. It is different from traditional mattress layers that use PTFE (iron fluoride)."
I searched with Xtrema and found a Korean patent published on April 8, 2021. Its English title is Xtrema T composition for coating providing iron-like texture to aluminum-based cookware and method for coating using the same (a Xtrema T composition for coating providing iron-like texture to aluminum-based cookware and a layer method for coating using the same). Its English abstract is translated into Chinese: "The present invention relates to a primer matte composition for ceramic matte layers, which comprises glue silicon dioxide, methyl trimethoxysilane, organic silicone glycol copolymer and acid catalyst, as well as a method of plastering iron patterning on the surface of the aluminium using the matte composition and thus prepared ratios. It involves a kind of aluminium cooker with a sticky iron texture. "
I think anyone with a little common sense can see from this summary that the Xtrema layer is not what merchants call "natural sand and stone." Also, you should be able to see that this layer is a "alternative cooking utensil". If there are risks related to the safety of aluminium products, please see if I used to publish Dr. Alzheimer's disease and was fried with fish
aluminium cans were harmful?
Aluminum is poisonous? Is the elderly stupid?
During the search, I found very strangely that Xtrema is an American company, and it specializes in producing and selling "pure ceramic utensils" rather than "ceramic utensils". The company was founded in 2004, and Xtrema is its registered trademark. So, why did Xtrema be used by Koreans to apply for a patent in more than ten years later, and then obtained a Korean patent in 2021, and at the same time it also became a registered trademark for ceramic matte utensils? I spent a long time searching but couldn't find the answer.
Regardless, Xtrema has a webpage that is well worth recommending, and it is titled Everything You Need To Know About Ceramic-Coated Cookware. I translate the key points as follows (red words):
How are ceramic slab cookware made?
Ceramic mattress is essentially any metal mat with a thin ceramic layer on top. The base material or metal core of flat bottom kettle is different depending on the brand. Some companies use yang oxide aluminum, a cheap metal known for its conductive properties. Other brands use tart or stainless steel.
As for ceramic layers, most of them are not real ceramics. They are actually "sol-gel" (Sol-Gel) foils containing silicon dioxide (sand) and other non-organic chemical substances. Solvent-gel is the first choice for applying ceramic mattresses to cookware to keep them from sticking.
Typically, manufacturers spray the solvent gel onto the metal substrate before hot-temperature burning. Depending on the manufacturer, the temperature range of this curing process can range from 400 to 800 degrees Wah.
Although the solvent-gel coating is technically harder than the PTFE coating and can withstand higher temperatures, most companies recommend that their customers not heat the ceramic coating to above 500 degrees. No matter how high the temperature is, the ceramic coating will decompose. (Note: PTFE is iron fluoride)
When the solvent-gel decomposes, the ceramic slab will lose its non-stick properties and the surface will become rough or sandy. Therefore, it is not usually recommended to use these flat-bottomed crocks in a dishwasher or under a baking pot.
Ceramic matte cooking utensils are not sticky?
The idea of ceramic non-stick utensils is to use inappropriate words. Ceramics themselves are not non-stick, which is why most companies use solvent-gel technology to create ceramic non-stick layers. The smooth surface of the
ceramic matte layer will usually degrade over time. Often exposure to high temperatures can speed up this process. Some experts believe that the life of ceramic mattresses is only one-sixth of that of PTFE mattresses.
Another important problem is how long the ceramic layer is. A well-maintained ceramic layer pot is expected to be used for one to two years. Considering its high price, this is not a long time.
Are ceramic non-stick cooking utensils safer than other non-stick utensils?
Due to the dispute surrounding fluoropolymers and PTFE, it makes sense to conduct a lot of scientific research on these chemical substances. Unfortunately, there is not much historical research on the long-term impact of solvent-gel on human health. This is not to say that one is inherently safer than the other. (Note: Xtrema is specialized in producing and selling "pure ceramic utensils", so it will of course inadvertently implying that "layer utensils" may not be safe)
As can be seen from the last paragraph above, there are currently no scientific evidence that ceramic utensils are safer than iron utensils. In fact, iron fluoride layer pellets have been widely studied, but there are still no evidence that they are harmful to human health under normal use. On the other hand, ceramic mattresses have not yet studied any health risks, so how can we say that ceramic mattresses are relatively safe?
Taiwan's Ministry of Welfare also said this: "The common non-stick layer is mainly polytetrafluoroethylene (PTFE), which is commonly known as iron fluoride. It is a cold-resistant, heat-resistant and corrosion-resistant polymer that can resist water and fat, and avoid sticking. In the early days, this type of layer would use perfluorooctanoic acid (PFOA) that interferes with endocrine secretion as a production aid. Due to safety concerns, the environment The Protection Department and the International have continued to ban it. In addition, studies have shown that PTFE materials will degrade only at about 360°C. This temperature is far higher than the normal cooking temperature and high-temperature baking (about 250°C). Therefore, normal use of non-stick layered products will not cause any safety concerns. "
