"What are you doing? Why are you doing with so many steamed buns?" Aunt Wang looked at her husband with confusion.

"I just saw an article saying that steamed buns will produce aflatoxin after more than three days. Eating them will cause liver cancer , so you have to throw them away quickly!"

It turns out that Aunt Wang's family likes to eat pasta such as steamed buns. Most of the staple foods in normal times are mainly steamed buns, and they steam a lot every time and put them in the refrigerator. What my wife was about to throw away was what she had just steamed and put in the refrigerator last week, so Aunt Wang felt a little wasteful.

In the end, the old couple had a big fight over the steamed buns, and no one allowed anyone, and in the end they didn't argue with any results. So what exactly is the aflatoxin in my wife’s mouth? Will steamed buns really breed toxins if they are stored in the refrigerator for more than 3 days?

What is aflatoxin?

Aflatoxin is a secondary metabolite produced by toxin-producing strains such as Aspergillus aflatoxin and Aspergillus parasitica. It is a toxic substance.

According to statistics from the Food and Agriculture Organization of the United Nations, Aflavine is one of the most important contaminated fungi in cereals in the world. Aflatoxin is one of the main mycotoxins produced by Aflatoxins, and has been listed as a class of carcinogens by WHO.

It is reported that 1 microgram per kilogram can induce cancer, and one microgram per kilogram is equivalent to one ton of food. There is only one large aflatoxin in sesame .

If you consume some foods containing aflatoxin for a long time, it will easily increase the risk of cancer, especially causing certain damage to the liver, entering the liver to stimulate liver cells and causing damage, causing liver lesions, and affecting personal health.

Can't I eat frozen steamed buns? Will aflatoxin be breeded? The doctor finally told the truth

From the above, I learned that aflatoxin is indeed very harmful to the human body. So can frozen steamed buns be eaten? Will storing in the refrigerator for three days really produce aflatoxin? This statement has attracted widespread attention.

Regarding this issue, relevant experts have conducted experiments:

Experts prepared 200 identical steamed buns, divided into 10 groups, each with 20. Each group is stored in the refrigerator for different times, and then the aflatoxin is tested.

The results found that steamed buns stored for more than 3 days did not produce aflatoxin, but the taste and texture of the steamed buns had some changes, and the nutrients and moisture in them were lost. Moreover, even steamed buns that were frozen for ten days did not produce aflatoxin.

Why is this?

Kexin Food and Nutrition Information Exchange Center Zhong Kai explained: The temperature in the refrigerator is very low, which is far from the temperature in the environment where aflatoxin is prone to breed. In daily life, you only need to pay attention to whether the steamed buns are moldy or have hair. If you don’t have them, you can eat them with confidence.

American Food Technology Association yun Wuxin experts also said: How long can steamed buns be stored and the hygiene level of the operation process are closely related. The prepared steamed buns are placed in a clean container and placed in the refrigerator. It is no problem to store for a few days, but the taste will be different from the fresh steamed buns.

To sum up, eating steamed buns that look normal for a few days in life will not pose a threat to health, so there is no need to worry too much.

These four foods are prone to aflatoxins. Please pay more attention to

, moldy dried fruits

. buy too many dried fruits during the Chinese New Year, such as pistachio , hazelnut , nuts, almonds, pecan fruit , etc. Over time, it will become moldy and spoil. At the mildest, there will be a scent, and at the worst, there will be a mass of mold.

These moldy dried fruits also contain a large amount of aflatoxin and cannot be eaten.If you accidentally eat it into your mouth, spit it out quickly, rinse your mouth with water, and spit out the water.

, self-extruded oil

Self-extruded oil poses great safety hazards, especially some bad merchants will use moldy rapeseed , peanuts or corn to squeeze oil, which is susceptible to aflatoxin infection.

In addition, the oil pressing equipment is not cleaned, which will also cause mold in the cooking oil. Therefore, try not to choose oil press in small workshops, but choose vegetable or animal oil produced by regular manufacturers.

. Wooden cutting board

Many families like to use wooden cutting boards and think that this kind of cutting board is more durable. However, if you do not pay attention to cleaning during use, it will cause residual food residues. In addition, it is easy to cause mold to occur in a non-ventilated and humid environment for a long time, and once mold is changed, a large amount of aflatoxin will be grown.

Use this chopping board for a long time is extremely harmful to health. In addition, chopsticks are tableware that needs to be used in daily life and are often in contact with food. If they are not clean and placed in a humid environment for a long time, they are also prone to mold. Moreover, if you eat with this chopstick for a long time, mold will enter the human body with the food, which will have adverse effects on your health.

, fungus that have been soaked for a long time fungus

fungus itself does not contain toxins, but long-term soaking in water will cause bacteria to reproduce. In the case of high temperature weather, molds and bacteria will reproduce faster, which is likely to contaminate black fungus and cause Aflatoxin contamination.

You can put the fungus in the refrigerator and soak them at low temperature, which greatly reduces the formation of aflatoxin. When you soak the fungus in , Tremella or fungus, it is recommended to soak a small amount and do not leave it overnight.

Reading extension - What to do if you accidentally eat foods containing aflatoxin?

, promptly induce vomiting

Aflatoxin is a highly toxic substance and is 68 times more toxic than arsenic. Once you accidentally eat a large amount of aflatoxin, it is easy to cause serious damage to the liver, and symptoms such as stomach discomfort, nausea, vomiting, decreased appetite, abdominal distension, and diarrhea are present.

After accidentally eating moldy food containing aflatoxin, it should prompt vomiting to prevent the body from absorbing a large amount of toxins and causing damage to the body.

. Drink more water

The purpose of drinking water is to help everyone speed up the discharge of metabolic products as much as possible, and to dilute the toxicity to a certain extent by drinking water, reducing the risk of possible poisoning.

. Seek medical treatment in time

If the patient accidentally eats food containing aflatoxin and develops symptoms of gastrointestinal discomfort, such as abdominal distension, diarrhea, abdominal pain, nausea, vomiting, and even fever, convulsions, fainting, etc., it is not advisable to continue to undergo conservative treatment at home. You should go to the hospital for treatment in time to avoid missing the treatment time, which will lead to worsening of the condition and causing adverse consequences.
