Lao Wang was criticized by his daughter for eating frozen steamed buns. Lao Wang is a native southerner, but he especially likes to eat steamed buns.
On this day, Lao Wang had a whim, so he thought about it and made a big pot. If you can't finish it, put it in the refrigerator to freeze it. If you want to eat it, defrost a few and steam them hot to eat.
After her daughter found out about this, she said: You can’t eat frozen steamed buns! The aflatoxin that breeds in can cause cancer.
This time Lao Wang was completely confused. How can steamed buns that are kept fresh cause cancer? Don’t supermarkets also sell frozen steamed buns? Can you eat frozen steamed buns? Will the aflatoxin that breeds cause cancer? Let’s find out next.
1. What takes away the health of steamed buns?
I don’t know since when, there has been a saying that “frozen steamed buns cannot be eaten because the aflatoxins that breed can cause cancer.” This is probably the worst time that the simple steamed bun has been hacked.
Aflatoxin is a toxic substance produced by the metabolism of Aspergillus flavus and Aspergillus parasiticus. Aflatoxin is extremely toxic and was classified as a natural carcinogen in 1993.
Aflatoxins mainly damage the health of the human liver and can cause liver cancer , induce kidney cancer , rectal cancer and other diseases. Aflatoxin poisoning is mainly divided into three types: acute poisoning , chronic poisoning, and carcinogenic poisoning.
Acute poisoning: The liver damage is relatively serious, and abdominal pain, difficulty breathing, hematuria, coma, etc. may occur.
Chronic poisoning: hinders the body's absorption of nutrients, leading to abnormal body growth and development.
carcinogenic poisoning: is currently the most carcinogenic chemical substance, and there is currently no specific antidote.
Food mold is the main cause of aflatoxin production. It is no exaggeration to say that aflatoxin may be present in moldy food. Such as moldy steamed buns, improperly stored rice, etc.
Aflatoxins are affected by temperature and moisture and can easily grow on foods such as grains, oils and nuts. Peanuts and their products, in particular, are foods high in aflatoxins.
Aflatoxin is a common mold found in warm areas. This is why the detection rate of aflatoxin is higher in tropical and subtropical areas. Generally, aflatoxins will breed rapidly in humid environments with temperatures around 33°C.
2. Is it true that frozen steamed buns cannot be eaten?
Is it true that frozen steamed buns cannot be eaten? the answer is negative. In summary, the growth of aflatoxin requires temperature and moisture, both of which are indispensable.
Nutrition experts conducted an experiment on frozen steamed buns. The nutrition expert put the sealed steamed buns into the freezer of the refrigerator and stored them for 6 days before taking them out.
After observation, it was found that the steamed buns that had been frozen for 6 days did not produce aflatoxin. This is mainly because the temperature of the freezer layer of the refrigerator is too low and dry, and does not meet the breeding conditions for aflatoxin.
Therefore, when freezing steamed buns, they must be sealed and stored separately. recommends using fresh-keeping bags and packaging. Try to layer foods and do not put them together with other foods to avoid food contamination and the breeding of aflatoxin.
In addition, the storage time of steamed buns should not be too long. It should be controlled within 8 days to avoid excessive loss of water and nutrients.
In addition, the refrigerator needs to be cleaned from time to time to reduce the growth of unhealthy microorganisms. For example, raw meat contains its own microorganisms, which can easily contaminate other foods. If things go on like this, it will pose a potential threat to health.
3. When taking out frozen steamed buns for consumption, you should pay attention to the following points:
, Observe whether the steamed buns have deteriorated
You can judge whether the steamed buns have deteriorated by observing the surface of the steamed buns. If the steamed buns have already deteriorated before freezing, even if they are placed in the refrigerator, it will not prevent the steamed buns from deteriorating.
When you see black mold spots on the surface of the steamed buns or smell a sour smell, it means that the steamed buns have deteriorated. If you eat this kind of steamed buns, it can easily cause gastrointestinal discomfort. In severe cases, you may be poisoned.
2. Full heating
Frozen steamed buns must be fully heated before eating. After being frozen for a long time, steamed buns will generally become harder. If it needs to be defrosted for consumption, it must be fully heated to restore the softness of the steamed buns before consumption. If the steamed buns are not heated enough, the inside of the steamed buns will still be frozen, which can easily cause irritation to the gastrointestinal tract after consumption, leading to indigestion and abdominal pain and diarrhea.
Summary:
Frozen steamed buns are not inedible. Steamed buns that have been sealed and frozen in a fresh-keeping bag for 8 days can be eaten normally after being confirmed that they have not deteriorated and have been fully heated. You don’t need to worry too much about unhealthy issues.
Frozen steamed buns do not necessarily breed aflatoxin and cause cancer. The growth of aflatoxin requires suitable temperature and moisture. The temperature of the freezer compartment of the refrigerator is generally minus degrees Celsius and is relatively dry, so sealed and frozen steamed buns will not breed aflatoxin, let alone cause cancer.
Do you know what is going on "Can't you eat frozen steamed buns? The aflatoxin that breeds can cause cancer?"
