Now that health awareness is increasing, people are paying more and more attention to food safety issues, and there are more controversies about steamed buns.
I don't know when frozen steamed buns can't be eaten. Storing in the refrigerator for more than three days will breed aflatoxin. Many people want to know the truth. Let's start with aflatoxins.
Aflatoxin: 68 times more toxic than arsenic
In simple terms, aflatoxins are metabolites of aflatoxins and parasitic aspergillus toxins, which belong to difuran ring toxoids. There are more than ten kinds of toxins. As early as 1993, it was designated as a class I carcinogen by the WHO.
How poisonous is it?
Maybe you have seen from TV series that someone drank arsenic and immediately vomited blood and died. Among them, the most toxic aflatoxin B1 is 68 times more toxic than the double poison in TV series!
You only need to take 20mg, you can kill an adult very quickly, even a small amount of intake can easily lead to toxin accumulation effect, cause liver damage, gastric dysfunction, reproductive system function decline and other problems, and even induce liver cancer, so People are more strictly on aflatoxin prophylaxis.
This substance is often found in moist, long-rotting grains, corn, peanuts, and mill oil. Pay attention to this kind of food at ordinary times, and deal with it in time if it becomes moldy. So is the frozen steamed bun in the refrigerator really inedible?
Can frozen steamed buns be eaten? Putting it in the refrigerator for more than 3 days will produce aflatoxin? Read or learn about it.
Seeing this, you may have understood that according to the widespread existence of syphilis, not all environments are related to the reproduction of aflatoxin. The most suitable temperature for aflatoxin is 26°C to 28°C. Relatively speaking, the higher the temperature The higher the temperature is, the faster the speed is, and the temperature for completely cracking aflatoxin is 280°C.
If the food is spoiled and moldy, there is such a substance in it, and if you want to kill it completely by ordinary cooking and heating, it can only be said that it is relatively less toxic. The refrigerator has no sunlight and no ultraviolet radiation all year round, and is relatively humid and dark, but the temperature inside, even the temperature of the fresh-keeping layer, is in single digits, which is not suitable for the growth of aflatoxin.
After the steamed buns are ready, wrap them in a clean container and store them in the refrigerator. It is no problem to put it for a few days, and it will not produce aflatoxin within three days as people say. It is steamed buns stored in the refrigerator, the taste will become dry and hard, not soft enough.
If the steamed buns are not stored properly, or the steamed buns are left outside, causing the steamed buns to become moldy, even a little bit, every bit must be thrown away, because the aflatoxin has grown, not only the steamed buns, but also other moldy foods, such as melon seeds and peanuts, moldy, Then throw it away, as mold may have infested it if you can't see it with the naked eye. Therefore, the rumors about carcinogenicity caused by aflatoxin produced by steamed buns placed in the refrigerator for three days are not credible. Don't read information on the Internet, and don't follow other people's advice. Whether it is true or not is unclear.
Which steamed buns should not be eaten

Steamed buns stored for a long time will turn black, and dark green spots indicate mold and deterioration. It is not recommended to use it again at this time. If you eat it at will, it will inevitably cause nausea, vomiting, diarrhea and other gastrointestinal discomfort. It is best to throw away such steamed buns.
- Sour steamed buns
Some people put steamed buns in the refrigerator, which is not wrong in itself, but the refrigerator is not cleaned for a long time, and raw and cooked food are mixed, resulting in a relatively harsh environment and shortening the shelf life of food. This situation not only produces odor, but also easily leads to bacterial reproduction and accelerated deterioration. Produces an unpleasant sour taste that is best lost.
- Steamed buns with sticky surface
If the steamed buns are stored for too long, the surface will feel sticky, and the bacteria-infected substances will decompose. This may be due to the unqualified quality of the flour, which will shorten the storage time. It is best not to eat such steamed buns, because it is easy to cause diarrhea and poisoning.
