Foreword: When there was no gas, every household seemed to have a big iron pot, and a variety of cuisines were also bred, such as hodgepodge, iron pot stew, etc., and even the bottom of the pot was nutritious, and such a dish called pot gray pork liver was born.
Later, when there was gas and lived in a building, the big iron pot obviously didn't work, so the hand-handled iron pot for home was derived, but you know what?
As early as 2011, CCTV once exposed the "poisonous iron pot" incident, which seems to have a great connection with these iron pots.
CCTV exposure
In 2011, China Central Television (CCTV) exposed a serious food safety incident involving a wok-made product made from discarded iron drums, which sparked public concern about food safety and environmental protection.
According to reports, some manufacturers have taken away discarded chemical drums, some of which used to hold methylene chloride, and some of which were once filled with dangerous chemicals such as isopropyl alcohol.
Are you saying these merchants are stupid? Actually, they are not stupid, after all, these barrels clearly have toxic chemicals written on them, and there are big skulls, but why do they want to take them?
There are only two words to describe it: black heart!
But having said that, it stands to reason that this kind of iron barrel should be strictly processed, stored and managed in a unified manner, and handed over to a qualified enterprise for further processing, not to mention entering the market for secondary use.
So, what kind of "poison" exists on these iron pots that have been reused? The reporter randomly purchased the iron pots and sent them to a professional testing center for testing.
Unexpectedly, the iron pot sample contains a variety of metal elements, which are extremely harmful to the human body, and also contain many toxic elements.
At that time, the mainland cast iron pot industry mainly followed the standards on product appearance and size, and there was no clear national mandatory standard for the quality of raw materials, which provided loopholes for illegal traders, resulting in a large number of woks made of discarded chemical iron drums on the market.
In 2013, CCTV exposed the poisonous iron pot incident again, and after exposing this incident two years ago, there were still factories with a fluke mentality, in Shangrao, Jiangxi, a factory used a waste chemical iron drum to cast iron pots.
The process was also revealed, with the factory first cutting and pressing the buckets into rectangular pieces of iron, which were then cut into round sheets.
The iron flakes are then treated with fire and sulphuric acid bubbles to restore their shine, and finally soaked in hydrochloric acid and lime water, polished, oiled and fitted with handles to make a seemingly normal wok.
These wok woks are sold at a low price in the market, and many people buy them at home, and restaurants and pot resellers buy them in large quantities, and the processing plants make a lot of money despite the low cost of raw materials.
Having said all that, what happens when I buy these pots, and what happens if I use them to stir-fry?
What's the harm
Since the original label has disappeared, we have no way of knowing what hazardous substances were once stored in these chemical barrels, and the barrels themselves are more likely to have hazardous substances such as organic solvents and heavy metals, and the potential health hazards cannot be ignored.
Workers carry out a series of cleaning and treatment processes to remove potentially harmful substances when processing iron pots, but it is difficult to ensure that every link is adequately cleaned, which is equivalent to the person who bought these "poisoned iron pots" spending money to buy a poison to take home.
During the heating process of the iron pot, the heavy metal elements such as cadmium, chromium and lead present in the "poisonous iron pot" are integrated into the food, causing irreversible damage to the human body.
Lead is the most common and most harmful heavy metal in the "poisonous iron pot", after entering the human body, it will interfere with the development of our nervous system, especially for children in the developing period is more deadly, children will show a state of reduced IQ after long-term exposure to lead, this is not over, this state will even affect the whole life.
Adults will also have many symptoms after exposure to lead, such as it may cause nervous system damage, dizziness, nausea, abdominal pain, diarrhea, chest tightness and a series of adverse symptoms.
Cadmium and chromium can also have many adverse effects on the body, cadmium can damage the digestive system, liver, and kidneys, while chromium can cause skin allergies, ulcers, and even cancer.
Therefore, chemical plants should improve the links in the industrial chain to improve the level of safety and security, which also requires the relevant regulatory authorities to increase the quality inspection of tableware.
But there will be people who are still doing disgraceful things in the dark, as consumers, we should improve the safety hazards, so, take the pot as an example, how do we usually choose?
How to avoid buying the wrong one
Nowadays, the market is flooded with all kinds of iron pots of uneven quality, and merchants hype up their own good goods, from the former iron pots to stainless steel pots to non-stick oil pots, and even some pots are designed with temperature alarms and other black technologies on the lid.
If you can't buy a "poisoned iron pot", we must first know that the poisoned iron pot is often made of light and inferior materials, which are easy to deform and have uneven heat conduction.
How to distinguish a real iron pot from a fake?
We can get close to smell that poisoned iron pots often emit a pungent smell, and the price is often very low, and there is a lack of effective inspection certificates to ensure its safety, which is what we commonly call three-no products.
It can also be judged by weighing the weight of the iron pot, generally speaking, a good quality iron pot is forged from pig iron, and its weight is relatively heavy.
It is also possible to observe whether there are rust stains in the iron pot, and the qualified iron pot is usually coated with anti-rust grease during the production process, while the inferior iron pot may ignore this link.
What are the standards for a real iron pot?
These pots have good thermal conductivity to ensure that the food is evenly heated, the structure of the iron pans is stable and not easy to deform, and the material of the iron pans is safe and will not contain harmful substances.
When buying an iron pot, we should also choose formal channels, regular places, and don't go for a small bargain, after all, there is a good saying - "you get what you pay for".
However, now many live broadcast rooms will also send some benefits such as Zhongfu bags, and the pot sent by tens of millions of fans and anchors is generally no problem, but if you want to test yourself, you can also use the above methods.
