I am a food lover, I like to eat and like to cook, I have used dozens of cooking pots, non-stick pans, stainless steel pots, coated pots, etc., which are used to use and finally use back to the iron pot.
Although the iron pot is a little heavy, it is really easy to use and durable, and the steel wool ball shovel can be used casually.
I have an iron pot at home, which was used by my relatives to boil eggs and rusted, and I raised them back with lard, and now I raise them shiny and shiny, and I am in a very good mood when I cook every day.
Many people, like me, have finally returned to iron pots, and some people believe that using iron pots to stir-fry vegetables can replenish iron for the human body.
In fact, this is a rumor, the iron of the iron pot is not the iron that our human body needs, and the iron of the iron pot cannot be absorbed by the human body at all.
So, don't listen to those who use an iron pot to treat anemia, and even supplement iron.
The dishes fried in the iron pot taste very fragrant, but there are many so-called Zhangqiu handmade iron pots on the market, which are actually not iron pots at all.
Some iron pots on the market can be bought for 30~40 yuan, and some even only have more than 10 or 20 yuan, in fact, this kind of iron pot is not a real iron pot, but a poisonous iron pot.
Why is an iron pot poisonous?
The poisonous iron pot is also called the "life-killing pot", which has been exposed many times at the CCTV 315 party earlier, but now there are still many small workshops in production and manufacturing, deceiving consumers.
In order to reduce costs, these unscrupulous businesses recycle some dangerous goods containers such as scrap iron sheets and chemical waste barrels to make iron pots.
Due to the large amount of heavy metals (lead, cadmium, mercury, arsenic, etc.) and harmful substances (some chemical waste barrels are also marked with skulls), the harmful substances will precipitate into the food during high-temperature cooking, turning the food into poison.
If you use such an iron pot for stir-frying, long-term consumption will increase the risk of cancer, damage to kidney function and other diseases, which is extremely harmful.
How to tell the difference between a poisoned iron pot?
(1) Abnormal appearance
Generally speaking, the iron pot will be treated with a layer of nitriding (i.e., the oxidation reaction of high temperature treatment) when it leaves the factory.
Its main function is to make the iron pot rusty, anti-corrosion, good iron pot after nitriding treatment, its surface is black or gray, the color of the whole pot is uniform.
The poisoned iron pot does not have this process, that is to say, it has not been treated with high temperature, so its color is not the oxidation reaction produced after high temperature, but the blue sprayed on.
If you look closely, you will find that there is a layer of coating on its surface that seems to be sprayed on, and these coatings will dissolve under high temperature and acid and alkali conditions.
(2) The smell of dry burning is heavy
Generally, the iron pot bought should be boiled, when the pot is boiled, if it is a poisonous iron pot, after being put on the fire to dry burn, the taste will be very heavy, and the green smoke is also very pungent, and some still have the smell of medicine, plastic or paint during the firing process.
After being heated at high temperature, a good iron pot will produce oxidation, and it will also become iron oxide, and its color is generally blue.
The inferior iron pot, the color difference is obvious, after dry burning, the blue color is gone, indicating that it is completely dyed, but it appears black or dark gray, which is caused by impurities such as lead.
(3) There is an abnormality in the scratch
Scrape the surface of the pot with a blunt object, and then wipe the scraped area with a paper towel, and there is obviously a metal-like substance of the same color as the pot on the paper towel of the poisoned iron pot.
And a good iron pot, scrape the pot with a blunt instrument, and it is still clean after wiping with a paper towel, from which you can clearly distinguish whether the iron pot has heavy metals exceeding the standard, or whether it is regular.
(4) There is a difference in listening to the sound
The sound of the authentic iron pot is crisp and loud, with a long echo, while the sound of the poisonous iron pot is relatively dull.
The above points are some of the ways that we ordinary people can distinguish without passing professional testing.
In the past, the older generation bought an iron pot casually and was an authentic and good pot, but now the iron pot really needs to keep your eyes open and tested and inspected many times before you can use it with confidence, which is too difficult!
