Nowadays, refrigerators are household appliances that every household has. They bring a lot of convenience to people's daily life. Refrigerators can effectively extend the storage time of food and maximize the taste of food. However, refrigerators also have disadvantages.
If you do not pay attention to the cleaning of the refrigerator, it may become a "culture medium" for bacteria. Generally speaking, it is best to clean it once a week, disinfect it once every two weeks, and thaw once every three months.
. Most families often clean the refrigerator once every six months or even a year. This practice invisibly increases the probability of bacteria and viruses growing. All foods have a shelf life. Some foods are kept in the refrigerator for more than a certain period of time. Even if they do not rot, they must be discarded as soon as possible, such as steamed buns.
What is Aflavine ?
Aflavin generally refers to aflavin, which is the metabolite of Aflavin and Aspergillus parasitic Aspergillus parasitic . It belongs to a class of carcinogens, which can damage human liver tissue, mainly cause liver cancer , and can also induce renal cancer , bone cancer, rectal cancer and other diseases.
In daily life, the aflatoxins that people can come into contact with mainly moldy nuts and their products, such as peanuts, walnuts, melon seeds, etc.
If you consume a certain amount of aflatoxin, in mild cases, symptoms such as abdominal distension, vomiting, stomach discomfort, and in severe cases, symptoms such as liver pain, ascites, and coma will occur. If aflatoxin is consumed for a long time, it will cause chronic liver damage, such as liver parenchymal cell deformation, cirrhosis and , and may even cause liver cancer!
Aflatoxin poisoning , there is no special antidote, and it is generally mainly used for detoxification, liver protection and symptomatic treatment.
In order to prevent aflatoxin poisoning, food should be preserved reasonably, avoid eating moldy food, pay attention to the shelf life of the food, and it is best not to choose "three-no products". If the above-mentioned poisoning symptoms occur, you should seek medical treatment immediately. What are the effects and functions of
steamed buns?
steamed buns are made of fermented flour and are easier to be digested and absorbed by the human body.
For who have excessive stomach acid , abdominal distension, indigestion, causing diarrhea, eating roasted steamed buns will make their stomachs feel comfortable and the symptoms will be relatively relieved. Steamed buns have the effects of replenishing energy, encouraging spirit, and protecting the stomach.
steamed buns are foods fermented from flour. The main nutrient is carbohydrate , which is the basic food for people to replenish energy. After the flour is fermented, it can decompose phytic acid in the flour that affects the absorption of calcium, magnesium, iron and other elements, thereby improving the body's absorption and utilization of these nutrients.
If the human body lacks vitamin B1 and vitamin B2, it will feel weak and listless, and it is easy to have symptoms of fatigue. Steamed buns are rich in vitamins such as vitamin B1 and vitamin B2, which can boost your spirits.
The calcium element in steamed buns is very rich. Calcium deficiency in the human body will lead to mental depression and stress. Therefore, eating some steamed buns for breakfast can relieve the pressure of the day and make people more energetic at work.
steamed buns are a fermentation product, so eating steamed buns is more conducive to the digestion and absorption of the human body, especially for people with weak stomach functions and thin body shape, as well as children and other groups, you should eat more steamed buns at normal times, so that they can protect the stomach and intestines and facilitate digestion.
steamed buns cannot be eaten in the refrigerator, will it breed aflatoxin?
If many families have problems with eating steamed buns, they will usually store them in the refrigerator, which can prevent the steamed buns from getting moldy and spoiling.
Some people say that steamed buns are easily produced by keeping them in the refrigerator for more than three days and can’t be eaten anymore. But in fact, when storing steamed buns in the refrigerator, you don’t have to worry about mold.
The growth temperature of aflatoxin is 10~33℃, especially around 26~33℃. Aflatoxin reproduces very quickly, while the freezing layer temperature in the refrigerator is generally below 0℃, making it difficult to breed mold.
If you put the steamed buns in the refrigerator, the temperature is generally between 2 and 8℃. This environment is not conducive to the growth of aflatoxin and is safer.
However, when putting the steamed buns in the refrigerator to refrigerate or freeze, try to avoid direct contact and try to seal them with a fresh-keeping bag, which can avoid moisture loss and bacterial contamination.
How to correctly store steamed buns?
Storing steamed buns in the refrigerator can extend the storage time of steamed buns, but it will have a certain impact on the taste of the steamed buns.
But some people say that steamed buns can also be stored at room temperature. Someone has conducted a related investigation and prepared two steamed buns. On the first day, they were placed in the room temperature refrigerator, on the second day, and on the third day, they compared the steamed buns with the first four. Finally, they found that both the steamed buns at room temperature and the steamed buns in the refrigerator were much harder than the steamed buns that had just been out of the pot, but the hardness was basically the same.
The steamed buns at room temperature tend to harden due to loss of water, and the steamed buns in the refrigerator become harden due to starch aging at low temperature.
If you want the steamed bun to become soft, you can choose to steam at high temperature, which will taste better. However, in order to extend the storage time of steamed buns, it is recommended that you try to store the steamed buns in the refrigerator.
What are the precautions for eating frozen steamed buns?
Refrigerator is not a "safe". Although bacteria will reproduce much slower, it does not mean there are no bacteria. When people take out steamed buns to eat, they must heat them up to kill potential bacteria.
Not only that, the temperature of frozen steamed buns is low. If heated enough, it may stimulate the human stomach and intestines and cause symptoms of diarrhea and abdominal pain.
During the process of frozen steamed buns, the water will crystallize and will quickly lose. Compared with fresh steamed buns, frozen steamed buns will be very "dry", which may "pull the throat", increasing the probability of indigestion. Therefore, before eating frozen steamed buns, it is best to drink more water to neutralize the stimulation of some frozen steamed buns, which is more conducive to the health of the esophagus and stomach.
steamed buns often, although it is a staple food, eating frozen steamed buns frequently is not a long-term solution.
On the one hand, frozen steamed buns have a poor taste, which may affect their mood when eating; on the other hand, during the freezing process, nutrients such as vitamins, trace elements are also relatively severely lost, and the edible value will be reduced. If conditions permit, it is better to eat as much fresh steamed buns as possible.
Suggestions: Try not to put 6 foods
Banana is a tropical fruit. Most tropical fruits are afraid of cold. The temperature in the freezer room of the refrigerator is too low, so it is easy to "freeze" the banana. When the banana is put in the refrigerator for storage, it may turn black and soft. Therefore, it is recommended that bananas should not be stored in the refrigerator.
Soft and elastic bread is a very popular food. The straight chain part of the starch is destroyed during the baking process. If the bread is placed in the refrigerator, the straight chain part will slowly stick, which will make the bread harder. The low temperature will speed up the bread harder. Therefore, to maintain the taste of the bread, it is not recommended to put the bread in the refrigerator.
The starch in onion is easily converted into sugar in a humid and cold environment, making the onion soft and rot and breeding bacteria. It will not only pollute the refrigerator environment, but also produce a odor to other foods. Therefore, it is not recommended to put onions in the refrigerator.
Potatoes cannot be stored in the refrigerator. If potatoes are placed in the refrigerator, starch will bind to asparagine, and chemical substance acrylamide will appear in it. This is a carcinogen, which will affect human health after consumption. After buying the potatoes, they can be stored in a cool and ventilated place.
Tomatoes cannot be stored in the refrigerator because the temperature in the refrigerator is about two to three degrees. When the tomatoes are put in, black spots will appear on the surface, and the meat will bubble, affecting the taste and nutritional value. Moreover, tomatoes with black spots have spoiled and are prone to cancer.
Garlic is best stored at room temperature. Stored in the refrigerator not only makes it easy to get damp, but also mix with the taste of other foods.
Tips: Can you continue to eat steamed buns when they are moldy?
steamed buns are stored scientifically and frozen in the refrigerator, and will not breed aflatoxin, so don’t believe rumors.
Of course, for the sake of health, steamed buns should not be stored for too long. Many people find that steamed buns sometimes become moldy, especially when the elderly are unwilling to throw them away, they will remove the "hair" areas and continue to eat them.
However, even if these moldy steamed buns do not grow hair, it is best to throw them away.
Many molds can produce mycotoxins under appropriate conditions. The mold can be visible to the naked eye and tends to be gray-green on the surface. It exists alone without smell, colorless and odorless, and cannot be distinguished by the naked eye. Even if the moldy area is removed, the toxins inside may have spread to other parts. In addition, the steamed buns themselves are softer and the holes are easier to spread, so it is not recommended to remove moldy areas and continue to eat them.
