Food is the essence of the people, and food safety is closely related to physical health in daily life. As a result, there is an increasing concern about food safety.
Aunt Liu is very industrious in life, and after retirement, time has become more abundant. She often reduces the burden of life for her daughter and takes care of her daily life.
Aunt Liu's daughter likes to eat steamed steamed buns at home, so Aunt Liu steamed a big pot for her.
But her daughter eats very little every time, so Aunt Liu thoughtfully put the steamed buns in a fresh-keeping bag and put them in the refrigerator for freezing.
Seeing her mother's behavior, the daughter hurriedly stepped forward to stop it, and said: "Frozen steamed buns are not good for your health and can cause cancer, and emphasized that you can't eat them for more than three days." ”
Aunt Liu is puzzled, why can the steamed buns that are often eaten be deserved for a long time to damage your health?
In life, how to preserve steamed bread as one of the staple foods that are often eaten and ensure its food safety is the answer that many people want to know. Let's find out today.
1. The harm of food mold
In life, sometimes due to improper storage, it is easy to cause problems such as mold and deterioration of food.
Especially in summer, when the outside temperature is relatively high, it brings new challenges to the preservation of food.
However, in order to reduce waste, many families often remove the moldy part and continue to take it.
However, once moldy food spoils, it will affect the food as a whole.
Even if not used, the deterioration will cause great harm to the human body and show a continuous deteriorating effect.
First of all, when the food is moldy, it is easy to invade the body with mold and bacteria, causing abnormal gastrointestinal flora.
At the same time, it causes indigestion and other conditions.
If this is done for a long time, it will seriously damage gastrointestinal health and induce the possibility of diseases such as bowel cancer.
In addition, when food spoils, it is easy to have abnormal changes in nutrients.
At this time, the food becomes poisonous, which can easily cause poisoning in the human body. There will be vomiting, abdominal pain, etc., and in severe cases, it will endanger life and health. Irreparable consequences.
Therefore, in life, for moldy food, do not continue to eat, you need to throw it away in time to avoid harm to your health.
Second, the CCTV experiment tells you the answer
Steamed buns are one of the most popular staple foods in many families. Freshly cooked steamed buns are very fluffy and full of taste, so they are often used as a must-have staple food.
Many friends, for the sake of convenience, often buy a big bag or steam a lot at one time. But how to properly preserve steamed buns has become a difficult matter in the hearts of many friends.
In order to further extend its shelf life, it is often chosen to be frozen. But there are many reports that frozen steamed buns can cause cancer.
Especially if long-term consumption can cause great damage to the body, but is this really the case?
In order to further answer the doubts of the people, CCTV came to a conclusion through professional experiments.
First of all, we need to clarify why many people think that frozen steamed bread causes cancer?
When food is stored for too long or improperly, Aspergillus flavus is more likely to appear.
The production of Aspergillus flavus, once ingested into the human body, will reduce the body's immune system.
At the same time, it causes significant harm and increases the risk of cancer.
Therefore, CCTV chose two sets of steamed buns of the same material and storage time for room temperature storage and frozen storage respectively.
After three days, they were tested together, and it was found that neither of them showed Aspergillus flavus, and they could continue to take it without endangering human health.
Therefore, the claim that steamed bread will cause cancer if it is frozen for three days is false.
In life, we can eat steamed buns that have been stored for three days without worrying too much about food safety.
So why is this the case? What are the conditions under which Aspergillus flavus is produced? In fact, Aspergillus flavus also needs two major conditions for growth, which are temperature and humidity.
When the food is stored above 28 degrees for a long time and the humidity is about 80%, it is easy for the food to deteriorate and induce it to produce Aspergillus flavus.
However, normal storage time and conditions usually do not meet the standards for the growth of Aspergillus flavus, so there is no risk to health.
But here, experts especially need to remind that although the steamed bread will not cause harm to the body when stored for three days, it is important not to relax too much and avoid storing the steamed bread for a long time before eating.
Because when the steamed bread is left in the refrigerator for too long, the nutrients inside it will be further lost, and the water will be greatly reduced.
Not only does it taste bad, but it is also easy to induce the possibility of deterioration, so steamed bread should be eaten as soon as possible within a reasonable range.
In order to reduce the harm to the body caused by the long storage time of steamed buns, we can reduce the quantity we buy, and at the same time, we can also reduce the amount we make when we make it ourselves at home.
3. How to properly preserve steamed buns
At this time, I believe that many friends will raise such a question, that is, how to properly preserve steamed bread in life to better extend its shelf life, and at the same time will not harm our body?
For the preservation of steamed bread, there are currently three main types of storage, which are room temperature preservation, frozen preservation and refrigerated preservation.
Usually room temperature storage is one of the more common methods. The main thing is to use a plastic bag to seal the steamed bread to prevent it from drying, and then place it in a dark place.
As long as it is used as soon as possible in a short period of time, there will be no possibility of spoilage of steamed bread.
If the weather is hot or the quantity of steamed buns purchased is large, you can choose to refrigerate them to keep them fresh.
It is generally not recommended to put hot steamed bread directly into the refrigerator, which will not only cause the steamed bread to deteriorate faster, but also have a certain impact on the refrigerator.
Generally, it should be sealed with plastic wrap or plastic bag after cooling, and placed inside the refrigerator for storage.
Finally, if it is difficult to consume the steamed buns in a short period of time, you can choose to freeze them.
However, putting it in the refrigerator is not once and for all, and it should also be consumed as soon as possible within the specified time, usually about a week, to avoid spoilage after too long storage.
Fourth, food safety
In life, what do we need to do to better ensure food safety and reduce health hazards? In fact, we mainly pay attention to the cleaning, storage and cooking of food.
1. Food cleaning
Cleaning food in daily life is one of the effective ways to reduce bacterial residue and breeding at the source.
Especially with the current development of science, many businesses often spray various pesticide products in order to make food more attractive and fresh.
The chemical components in pesticides are extremely damaging to the human body. So be sure to do a good job of cleaning.
For the cleaning of food, it can be divided into three parts: vegetables, fruits and meat.
The cleaning of fruits is relatively simple, only need to use a special fruit cleaner or put some baking soda starch to help remove bacteria and other impurities on the surface of the fruit.
For the cleaning of vegetables, there is also a certain gap in the cleaning method for different types of vegetables.
Usually for leafy vegetables, the surface can be cleaned directly with baking soda or salt water.
When it is difficult to clean the surface of food such as cauliflower, it is necessary to soak it to eradicate bacteria.
Finally, meat products can be rinsed repeatedly with rice washing water or clean water before cleaning.
At the same time, for meat products, hot water should be blanched to achieve the eradication of bacteria.
2. Shelf life of food
For the shelf life of food, it is the most important thing we should pay attention to in life.
Not only do you need to check whether the shelf life of food is within a reasonable range when you buy it, but you should also pay attention to it after buying it and use it at home.
For fresh meat, it is best to consume it as soon as possible within two or three days.
For the shelf life of rice, noodles and oil, which are common in life, it is usually about one to two years.
However, in order to reduce the burden of procurement, many middle-aged and elderly friends often encounter discounted goods in the supermarket and buy multiple barrels of soybean oil at one time.
However, the use time is relatively slow, and there is a long-term accumulation of oil, resulting in the expiration of edible oil.
At this time, once it is found that it exceeds the edible range, it should be discarded in time, and do not continue to take it to harm yourself.
3. Food storage
The storage of food can help us to further extend the shelf life of food.
But food should be sorted when it is stored.
Raw meat needs to be packaged separately to prevent it from being affected by the refrigerator or other foods, which can cause bacteria to grow and spread.
At the same time, attention should also be paid to the distinction of types in the process of food preservation.
Many friends think that all the food in the refrigerator can be stored, but in fact, many foods will not only not extend their shelf life after being put in the refrigerator, but will also accelerate the loss.
The first is tropical fruits, which are difficult to preserve once they are put in the refrigerator, and can also cause frostbite and even faster decay.
Secondly, cucumbers, green peppers and other foods are easy to turn black or speed up the rotting speed after being put in the refrigerator.
It is important to note that chocolate and other foods should not be put in the refrigerator, as it will cause hoarfrost, mold and spoilage.
4. Food cooking
Finally, one of the main things we need to focus on is the cooking of food.
In order to meet the needs of the taste buds, many friends often choose heavy oil, heavy salt, and heavy spicy flavors.
But in fact, in many cases, under high temperature heating, it is easy to lose nutrients in many vegetables, which is not conducive to the nutritional supplement of the human body.
Taking heavy-tasting foods for a long time will also continue to stimulate the taste buds, cause taste degradation and damage to gastrointestinal health, and induce obesity and other problems.
Therefore, we should try our best to ensure the original nutrition and taste of the food, and achieve a light diet.
epilogue
Storing food in life seems to be a casual small problem, but in fact, if you don't pay attention to the details and specific operation methods, it is easy to have food health hazards.
Not only is it harmful to physical health, but it can also lead to various diseases and increase the risk of cancer in the long run.
So in life, we need to raise food health awareness and pay attention to food safety.
