So is it harmful for pregnant women to use disposable lunch boxes for their children?
Is it harmful for pregnant women to use disposable lunch boxes for their children? There are several kinds of disposable lunch boxes, depending on which one you use. There is also whether the temperature of food is very high, even if it is toxic, how toxic it is, how high its content is, whether it can be ruled out by the body and so on. Also, the first three months are the baby's brain visceral formation period, which is very important.
It's been eight months, so it's better to have prenatal examination on schedule and closely monitor whether the fetus is deformed. If problems are found, the pregnancy should be terminated in time. This makes me feel a little sad, because I was infected with the virus at the beginning of pregnancy, and the doctor advised me so. Fortunately, my children are safe and healthy, and I hope to bring you some of my good luck.
If so, don't worry too much, so pregnant women will also produce toxins if they think too much. In today's China, no place is non-toxic and pure, including food, which must be carefully selected. This is not only your personal sorrow, but also the sorrow of the whole society.
What harm does the hotel disposable lunch box have to pregnant women?
Disposable lunch boxes are foamed plastic tableware. If the food is more than 65 degrees, it will precipitate its own toxins and invade the food, just like plastic bags can't withstand high temperatures. Moreover, if the process control is not good during the processing, the toxicity will be even greater. Eating with such a lunch box is equivalent to chronic poisoning. Although the toxicity is weak, long-term use will still cause harm to liver and kidney.
In addition, some unscrupulous merchants produce unqualified disposable lunch boxes in order to reduce costs. Unqualified disposable lunch boxes mainly contain a large number of toxic substances such as industrial calcium carbonate and paraffin wax, and some also use waste plastics.
Wang Zhao, director of hematology department of Beijing Friendship Hospital, said that long-term use of unqualified disposable lunch boxes containing a large amount of industrial calcium carbonate will have an impact on the metabolic system of the human body. First of all, it is easy to form gallstones and kidney calculi. In addition, industrial calcium carbonate contains a lot of heavy metals, which may be more harmful to human body.
Because it contains lead, lead is also very harmful to the digestive tract and nervous system of human body. Children, in particular, are in the developmental stage, and their nervous system is in the process of formation. After eating a lot of lead, it will have an impact on the child's nervous system, and ADHD will occur.
Due to the addition of a lot of calcium carbonate, industrial paraffin and recycled waste, the evaporation residue (n-hexane, acetic acid) of the product seriously exceeded the standard. Therefore, it is not recommended to use disposable lunch boxes frequently.
Especially for pregnant women, if pregnant women often use disposable lunch boxes, it will not only harm the liver and kidneys, but also threaten the baby's health. For the health of yourself and your baby, it is best to stay away from this disposable tableware.
Disposable lunch boxes, also known as white pollution, are also harmful to our environment. Please try not to use disposable lunch boxes. Ok, that's all for this issue of hotel safety knowledge. In the next issue, we will learn how to eat safely in hotels, so stay tuned.
Is it harmful for pregnant women to use disposable lunch boxes for their children? 2 hazards of disposable lunch boxes.
According to the regulations, the main raw material for producing lunch boxes is polypropylene, with a content of about 80%; As a filler, the content of industrial calcium carbonate should not exceed 20%. The surface of qualified lunch boxes should be smooth, free of impurities and black spots. Inferior disposable lunch boxes contain a lot of toxic substances such as industrial calcium carbonate and paraffin. Some also use waste plastics and talcum powder to produce lunch boxes.
According to the reporter's understanding, the wholesale price of a qualified environmental protection lunch box is generally above 0. 15 yuan, while the wholesale price of inferior lunch boxes is only 70 cents. Therefore, in order to reduce costs, many catering operators buy a large number of inferior disposable lunch boxes.
The early use of disposable lunch boxes containing a large amount of industrial calcium carbonate is harmful to human health. When these disposable plastic lunch boxes are soaked in hot water, heated by microwave oven or even the food temperature is slightly higher, the chemicals added in the lunch boxes will dissolve with the water, vinegar and oil contained in the food and enter the human body with the food, thus causing indigestion, abdominal pain and liver disease.
It is worth noting that industrial calcium carbonate contains a large amount of heavy metal-lead, which is also very harmful to the digestive tract and nervous system of human body, especially to children in development. After ingesting a large amount of lead, it may affect the nervous system, such as ADHD.
Types of lunch boxes
1, microwave lunch box
The texture is thick and strong, and it won't break no matter how you fall. When the temperature is 140℃- MINUS 30℃, it can be cooked in microwave oven or refrigerated in freezer. No embrittlement, no aging. The box is generally glass-colored, clear and transparent.
The lunch box has a built-in small steaming rack, which provides convenience for steaming noodle products, and has the function of dripping water to keep the original flavor of food, so as to heat oily food without water.
2, insulated lunch box
Lunch boxes that can keep the temperature of meals can be divided into several types, such as stainless steel liners and tempered glass liners. Different materials have different thermal insulation properties. Vacuum heat preservation can be 10 hour, and heat preservation and cold preservation can be 24 hours.
3. Military lunch box
Professional lunch box for marching troops. Generally light and small, easy to carry, not easy to rust, in addition, strong plasticity, can avoid bumping on the aluminum body; Products can be used as pots in extraordinary times.
In addition, it also has portability and portability functions. Aluminum is light, reduces load, is generally thinner, conducts heat quickly, saves fuel, and has lower cost compared with military metal and steel products, so it is suitable for large equipment.
4. Plastic lunch boxes
A lunch box made of plastic. The raw materials of plastic lunch boxes cause minerals and additives added in the lunch boxes to dissolve with water, vinegar and oil contained in food, so it is easy to produce odor.
5. Disposable lunch box
Disposable lunch box made of foamed plastic. Also called white lunch box.
6, electric lunch box
It is a new type of portable lunch box, which is based on the insulated lunch box, made of heating materials and connected by electric connecting wires. Put the food to be eaten into the lunch box, measure a cup (about 50g) of drinking water with a small measuring cup, put it into the food box, plug in the power supply on the top cover, turn on the heating indicator for 30 minutes, turn on the heat preservation indicator and turn off the heating indicator, and it is expected to be finished in half an hour.
At this time, you can unplug the power supply and preheat it for 20 minutes before eating. If you don't eat for a short time, you can continue to turn on the power to keep the food in the lunch box hot, and the heating time will be slightly extended in the cold areas in the north.
Step 7 Fold the lunch box
In particular to a foldable portable lunch box. The portable folding lunch box is mainly made of hard materials, which mainly includes a box body, a box cover matched with the box body and a hard card for clamping the box body. The box body consists of a box bottom and a box wall, and there are creases between the box bottom and the box wall and on the side of the box wall. The creases are made of flexible materials, and the box body can be folded into sheets due to the matching of the creases.
Is it harmful for pregnant women to use disposable lunch boxes for their children? The main raw material for producing lunch boxes is polypropylene, the content of which is about 80%; As a filler, the content of industrial calcium carbonate should not exceed 20%. Polypropylene has strong plasticity, and the produced lunch box has good use strength and is not easy to deform.
Industrial calcium carbonate is a kind of stone powder with poor plasticity, and it is difficult to stick together if the powder is used excessively. Therefore, the produced lunch boxes are prone to quality problems such as softening and leakage.
Soft to the touch, easy to tear and smelly, these are the same characteristics of these unqualified disposable lunch boxes. Soft feel makes the lunch box very inconvenient to use, and even causes things like food or soup to overflow when eating; This smell is a clear sign that the materials used to make lunch boxes contain toxic substances.
Disposable lunch boxes are foamed plastic tableware. If the food is more than 65 degrees, it will precipitate its own toxins and invade the food, just like plastic bags can't withstand high temperatures. Moreover, if the process control is not good during the processing, the toxicity will be even greater. Eating with such a lunch box is equivalent to chronic poisoning. Although the toxicity is weak, long-term use will still cause harm to liver and kidney.
The state prohibits the use of fluorescent whitening agents in the processing of food and food-related products, because once absorbed by the human body, fluorescent whitening agents will destroy the protein of cells, which is one of the potential carcinogenic factors. At the same time, benzene ring organic compounds contained in fluorescent whitening agents will weaken the healing ability of wounds.
Even disposable plastic tableware made of new materials has potential safety hazards. When the temperature exceeds 100℃, the disposable foamed lunch box will be deformed, especially when it is filled with oily food or heated by microwave oven, unpolymerized styrene monomer will enter the human body, leading to poisoning. Not only that, the plastic itself will be melted and eaten into the human body, which will be life-threatening when accumulated.
As can be seen from the above, disposable lunch boxes cannot be heated. If heated, they will be deformed, and at the same time, some toxic substances will enter the food. If you eat these foods regularly, it is easy to cause some symptoms and even life-threatening, so it is best not to use disposable lunch boxes, let alone heat them.
What are the hazards of disposable tableware to human body?
Disposable lunch boxes are mainly composed of polystyrene, ethylene and other polymer compounds, which are difficult to decompose and toxic, and will not degrade when buried in soil 100 years. Because it is difficult to degrade, it will also cause new pollution to the environment. It is white pollution, which will release a lot of toxic gases when burning, and will not rot for 200 years, causing serious harm to the environment.
At the same time, because the concentration of harmful substances in some foamed tableware raw materials exceeds the standard, the process control is not good during processing and the temperature is too high during use, tableware will be "poisoned".
In general qualified disposable plastic tableware, the amount of polypropylene accounts for 70% to 80%, and the rest is filler. However, many manufacturers added more than 50% talcum powder and calcium carbonate to their products, which caused the acetic acid content in tableware to exceed the standard seriously.
When the food is soaked in hot water, the microwave oven is turned on and even the food temperature is slightly higher, harmful substances will dissolve in the food, and long-term intake will lead to indigestion, gallstones and liver system diseases. If the tableware contains industrial paraffin, it may even cause cancer.
The harm of disposable tableware to human body is introduced in detail above. This thing not only brings convenience to people, but also does harm to the body, and the harm is not limited to this. The impact of disposable tableware on the environment is obvious, which destroys the environment, mainly littering, and its substances will not decompose for a hundred years, which is the cause of environmental pollution.
