In fact, the steamed stuffed bun itself is not toxic, but because it has been left for too long, it has become moldy and deteriorated, and a large amount of aflatoxin is produced, which will cause harm to health if ingested too much. There may be people who don't know much about aflatoxin, which is a first-class carcinogen with strong toxicity. Intake of 1 mg of aflatoxin may cause cancer, while intake of 20 mg may be fatal, so you must avoid contact with aflatoxin in daily life. Some people say that if steamed bread is kept in the refrigerator for more than three days, it will produce aflatoxin. Is this true?
If steamed bread is kept in the refrigerator for more than three days, will it produce carcinogens?
Steamed bread is a staple food that people often eat. Because it is cheap and good, they often buy a lot. When many people can't finish eating, they will put steamed bread in the refrigerator. Can steamed bread be eaten after it has been in the refrigerator for more than three days? Yes, but it is not recommended. Although it is difficult to produce aflatoxin when the refrigerator is clean, steamed bread is a starchy food, which is easily contaminated by bacteria. In addition, some people like to stuff all kinds of food into the refrigerator, which may lead to the deterioration of steamed bread, and there will be certain security risks. In addition, if the steamed bread is left for too long, the taste will become worse. It is best to eat it on the same day, and it is not recommended to leave it for too long.
Although putting steamed bread in the refrigerator for more than three days may not produce aflatoxin, some foods in the refrigerator for too long may breed harmful substances. If you have the habit of putting them in the refrigerator, you'd better change them early.
The refrigerator is not "everything", and it is not recommended to put some foods in the refrigerator.
1.? An endless supply of food. Now, in order to save trouble, people like to cook a lot, and prepare the meals for the next day. The extra meals will be put directly in the refrigerator and then taken out to heat up when they want to eat the next day. This kind of behavior seems to be very convenient, but there are certain health risks. For example, some seafood and green leafy vegetables may produce substances harmful to the human body after overnight, which will cause damage to the liver if eaten. If eaten in large quantities for a long time, it will be very unfavorable to health.
2.? Tropical fruits such as bananas and pineapples. In order to prevent the fruit from spoiling, it is a routine operation for everyone to put the fruit in the refrigerator. But in fact, tropical fruits are not suitable to be put in the refrigerator. On the one hand, they will emit ethylene after being put in, which will accelerate the ripening speed and may have a certain impact on the taste. On the other hand, when the refrigerator temperature is low, the fruit is easy to rot and turn black. Banana is a typical example. At this time, the fruit will breed bacteria, and it may also pollute other foods in the refrigerator and eat "bacterial pollution sources", which will also bring bad effects to health.
These two kinds of food are not recommended to be put in the refrigerator. When buying or cooking food, it is best to exercise restraint, get as much as you can, and buy as much as you can. Even if the refrigerator can keep fresh, it does not mean that it will not go bad. The existence of the refrigerator does bring a lot of convenience to people's lives, but many people don't know how to use it correctly. They just stuff it casually. Fruits, vegetables, meat and even snacks are all stuffed in, thinking that everything will be all right. In fact, it is not. If the refrigerator is not used correctly, it will only breed bacteria, produce carcinogens and cross infection.
The correct way to use the refrigerator: when using the refrigerator, don't be too "casual". For the sake of your own health, you should pay attention to it. When putting in food, it is best to mix raw and cooked food separately, which is not only easy to cross-taste, but also easy to infect bacteria with each other. When storing ingredients, it is recommended to use small boxes or sealed bags, which are classified and placed, convenient to take and not easy to breed bacteria. If the meat is frozen in the refrigerator, it is not recommended to put it in the refrigerator after thawing, otherwise more and more bacteria will grow, which may lead to diarrhea or even poisoning, so don't thaw it repeatedly. The refrigerator should be cleaned regularly at ordinary times, preferably once a week and once a month, so as to avoid breeding a large number of harmful bacteria in the refrigerator.
