Can frozen buns be eaten? Will produce aflatoxin? The doctor explained, let's find out

Today, almost every household has a refrigerator. The existence of refrigerators has also brought great convenience to people's lives. For example, some foods with a short shelf life can be stored in the refrigerator, which can reduce food waste.

The food in the refrigerator cannot guarantee that it will not deteriorate completely. Some foods have a limited shelf life and will deteriorate if they are stored in the refrigerator for a long time.

Recently, there have been rumors that frozen steamed buns cannot be eaten because they produce aflatoxins that are harmful to humans. Is there any scientific basis for this statement? Let's see how the doctor explains it.

01

Can I eat frozen steamed buns? Will produce aflatoxin?

Steamed buns are the staple food of northerners. Because they have a strong sense of satiety, can replenish energy for the body, and are cheap, most people in the north will choose to eat steamed buns.

When buying steamed buns, everyone will buy a few kilograms. If they can't finish it, they store the leftover buns in the refrigerator. Especially now that the New Year is approaching, a lot of steamed buns will be steamed at home, and then eaten slowly in the refrigerator.

The doctor said that frozen steamed buns can be eaten, and if it does not exceed three days, it will not produce aflatoxin.

If the steamed buns in the refrigerator are stored for more than three days, they may be affected by the temperature and humidity of the food, causing bacteria to grow in them.

If the surface temperature of the food is between 12 degrees and 40 degrees, a large amount of aflatoxin will grow. If the surface humidity of food exceeds 79%, and the moisture content of gold exceeds 98%, aflatoxin will grow on the surface of food.

Therefore, if the steamed buns are frozen in the refrigerator, the surface humidity and food temperature cannot meet the requirements of aflatoxin, but the worst time to store food should not exceed three days.

02

What is aflatoxin?

Aflatoxin, a Class I carcinogen, is common in nature and has caused the sudden death of millions of livestock, and it is a highly toxic substance that is extremely toxic.

The toxicity of aflatoxin B1 is 68 times that of arsenic and 10 times that of potassium cyanide. It is very destructive to liver tissue, so aflatoxin is very toxic, so pay attention as much as possible.

03

In daily life, these three foods are also prone to aflatoxin

moldy fruit

Fruits are high in moisture and high in sugar, so they are surrounded by a hungry army of microbes, including mold, which is a major contributor to fruit mold and rot.

Moldy fruit is hidden in the moldy fruit, and it will cause harm to the body's gastrointestinal function, kidney function, and liver function after eating, so don't eat moldy fruit.

spoiled peanuts

Aflatoxin is easily dissolved in peanut oil, especially moldy peanuts are the root cause of aflatoxin, so throw away peanuts quickly after they have deteriorated, and do not continue to eat them.

If you accidentally eat spoiled peanuts, it will cause oil containing aflatoxin to enter our body, increasing the risk of aflatoxin poisoning, so pay more attention.

soaked fungus

If the black fungus is soaked for more than 8 hours, a small amount of bacteria and other microorganisms will be produced. If the soaking time exceeds 24 hours, the harmful substances in the black fungus will increase.

There will be more and more harmful bacteria and toxic metabolites in black fungus. Food poisoning may occur after eating long-soaked fungus, so it is recommended not to touch it.

In addition to fungus, fungal food soaked for a long time will also contain toxic substances such as bacteria, which can cause toxicity, so pay more attention to this small detail.
