Most of the friends who often cook in iron pots have had such an experience, and there are always some small black slag on fried meals, what are these "dirty things"? These black slag are substances produced after iron is oxidized or food is overheated, and occasionally eating some will not cause immediate illness, but long-term consumption may be detrimental to health.
What is the reason why the iron pot fell black slag The iron pot coating can still be used
There are four main reasons why the iron pot drops black slag
One is not wiped dry after use, easy to rust when wet, once heated, rust reacts with certain ingredients in the food, easy to produce black slag; the second is acid corrosion, cooking some acidic food or phenol-containing food, such as hawthorn, lotus, etc., chemical reactions will occur to produce black slag; third, the temperature of the stir-fry is too high, the food is carbonized, which is what we often call stir-frying; the fourth is that the cleaning is not thorough, and the impurities in the pot are easy to produce black powder under high temperature conditions.
No matter what the reason, these black slag ingredients are not conducive to health, may cause nausea and vomiting, diarrhea, poor appetite, etc., if repeated brushing will appear, it is recommended to quickly change the pot.
Correct use and maintenance can reduce the phenomenon of corrosion of the iron pot and prolong the service life: can not be scrubbed with detergent and rough things, as far as possible with a soft texture of the rag scrub; after brushing the pot, the water in the iron pot should be wiped clean or dried to prevent rust; if the iron pot is rusty, don't worry, you can heat it, and then use a rag dipped in vinegar to wipe it off.
Can the iron pot still be used if it is coated?
The iron pot is painted to indicate that the iron pot has a coating, and the role of the coating is generally to prevent the pot from rusting and cooking without sticking to the pan. Because the coating falls off when stir-frying, the pot will rust. And eat the coating material is generally not good for the human body, it is recommended that you better change a pot, pay attention to the materials of the pot and whether there is a coating when buying new, do not blindly believe that the merchant said "stir-fry non-stick pan" those ~, buy the general stainless steel kind of iron pot good, cheap and practical!
Note: When the uncoated pot is first used, it may still have a little rust if it is not dried, but after the pot of stir-fry is used for a period of time, it will generate its own protective film, and it will not rust in the future.
In addition, the advantage of using an iron pot is that the iron in the pot is one of the necessary metal elements of the human body, and the use of iron pots and pans every day can just add a trace amount of iron to the human body.
How to handle the new iron pot
The newly purchased iron pot cannot be used directly to stir-fry, and it is necessary to "send the pot" first. The so-called hair pot is to first burn the pot red, pour in some cooking oil (if there is waste cooking oil containing precipitation can also be), pay attention to do not start a fire, and then use a handful of green vegetable leaves to repeatedly wipe the pot, while burning while wiping, the bottom of the pot side is all wiped, leaving no dead ends. Wipe the whole pot black and shiny, and the pot will be ready. There will be no rust in washing the pot and stir-frying. Usually after washing the pot, wipe the water in the pot clean, it is best to hang it up, so that it will not regenerate rust.
