Southerners like to eat rice, help people like to eat steamed buns, and prefer to steam their own steamed buns. Suffice to say, they steam a big pot every once in a while, and there's a lot of competition every holiday season. The steamed buns at home are delicious.

Now that the health awareness is constantly improving, 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. Storage for more than three days in the refrigerator can breed aflatoxins. Many people want to know the truth. Let us first understand aflatoxins.
Aflatoxin: 68 times more toxic than arsenic
In simple terms, aflatoxins are metabolites of aflatoxins and parasitic aspergillus, which belong to the bifuran ring toxoid. There are dozens of toxins. As early as 1993, it was called WHO class I carcinogen.
How poisonous is it?
Maybe you have seen from the TV series that someone drank arsenic and immediately vomited blood and died. Among them, the most toxic aflatoxin B1 is 68 times more than the double poison in the 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 the accumulation of toxins, causing liver damage, gastric dysfunction, reproductive system function decline and other problems, and even induce liver cancer, so People take aflatoxins more strictly.
This substance is often found in moist, long-rotten grains, corn, peanuts, and small mill oil. Usually pay attention to this kind of food, if it is moldy, it must be dealt with in time. So are the frozen steamed buns in the refrigerator really not edible?
Can you eat frozen steamed buns? Will aflatoxins be produced in the refrigerator for more than 3 days? Read it 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 more The higher the speed, the faster the self-speed, and the temperature for complete lysis of aflatoxin is 280 °C.
If the food is spoiled and moldy, there is this substance in it, and if you want to kill it completely by ordinary cooking and heating, it can only be said to be relatively less toxic. The refrigerator has no sunlight all year round, no ultraviolet radiation, and it is relatively humid and dark, but the temperature inside, even the temperature of the fresh-keeping layer, is in the single digits, which is not suitable for the breeding of aflatoxins.
When the buns are ready, wrap them in a clean container and store in the refrigerator. It's ok for a few days and doesn't produce aflatoxins in three days as people say. It is the steamed bread stored in the refrigerator, the taste will become dry and hard and not soft enough.
If the steamed buns are not stored properly, or the steamed buns are left out, it will cause the steamed buns to become moldy, even a little bit, every bit must be thrown away, because aflatoxin has grown, not only the steamed buns, but other moldy foods such as melon seeds and peanuts are moldy, Then throw it away, as the mold may have run rampant without being visible to the naked eye. Therefore, the rumor that steamed buns are stored in the refrigerator for three days to produce aflatoxin and cause cancer is not credible. Don't read information online and don't follow other people's advice. True or false is unclear.
Which buns can't be eaten
- Obvious moldy buns
Steamed buns that have been stored for a long time will turn black, and dark green spots indicate mildew and spoilage. It is not recommended to use it again at this time. If eaten casually, it will inevitably lead to gastrointestinal discomfort such as nausea, vomiting, and diarrhea. Best to throw away such buns.
- Sour 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 the raw and cooked food is mixed, which leads to a relatively harsh environment and shortens the shelf life of the food. This situation not only produces odor, but also causes bacteria to multiply and accelerate deterioration. Produces an unpleasant sour taste, which is best lost.
- Sticky steamed buns
If the steamed bread is stored for too long, the surface feels sticky, and the bacterial infection material is decomposed. It may be because the quality of the flour is not up to standard, which shortens the storage time. It is best not to eat such steamed bread, because it is easy to cause diarrhea and poisoning.
