What is the harm of using a plastic bag to make rice 10

It will be toxic. First of all, plastic bags contain plasticizers. The so-called plasticizer is the plasticizer mentioned by Taiwan some time ago, the plasticizer DEHP is an environmental hormone, although the toxicity to the human body is not clear, but it is widely distributed in various foods, its toxicity is much higher than melamine, which will cause immunity and fertility to decline.

When the plastic bag comes into contact with the hot water or hot grease contained in the packaged food, the plasticizer will be dissolved in large quantities, and the amount of dissolution is proportional to the plasticizer content in the plastic bag.

Therefore, do not use plastic bags to hold food, especially if it is hot.

Plastic lunch boxes are harmful when heated as well as for a long time.

1. Plastic products also have a shelf life, after expiration, the plastic will age, appear discolored, brittle, such as found that the plastic box used is yellow or no longer transparent, should be replaced as soon as possible. After the plastic lunch box is used for a long time, the inside will be uneven, and the missing part will be eaten into the stomach.

2. Each plastic has its heat resistance limit, among the materials used in food, the most heat-resistant is polypropylene (PP) that can withstand 140, followed by polyethylene (PE) can withstand heat 110, and polystyrene (PS) can only withstand heat to 90. Commercially available plastic lunch boxes for microwave ovens are mainly made of PP or PE, if the temperature exceeds their heat resistance limit, the plasticizer may be released, and a large amount of plasticizer may be ingested for a long time, which may damage the liver, kidneys and affect development and growth.

Pros: Convenient, no need to wash dishes.

Harm: Plastic bags are easy to release toxic substances when heated; unhygienic; Plastic bags are not easy to degrade and pollute the environment.

Easy to carry, save trouble and save time.

The harm of using a plastic bag to hold rice:

Medical experts pointed out that food, especially cooked food, is often easy to spoil after being packaged in plastic bags, and people can easily cause vomiting, diarrhea and other food poisoning symptoms after eating such spoiled food. In addition, the plastic itself will release harmful gases, due to the long-term accumulation in the sealed bag, the concentration increases with the increase of sealing time, resulting in different degrees of contamination of the food in the bag, especially the impact on the healthy development of children.

1. The particularly dark-colored plastic bags often used on the stalls have great hazards. It is reprocessed from waste plastic products, which is extremely harmful to the human body and cannot be used to hold food for direct consumption; In addition, polyvinyl chloride plastic products cannot be used to store alcoholic foods and oily foods, otherwise the lead in the bag will dissolve into the food; At the same time, this kind of plastic bag cannot hold food with a temperature above 50°C.

2. At present, the plastic bags sold and used in the market, the vast majority of them are produced by small enterprises or family workshops around the country, and a considerable number of them are recycled plastic products, which are processed by using waste plastics, industrial wastes and plastic waste discarded by medical institutions collected by garbage stations. These recycled plastics contain germs and carcinogens that are seriously excessive in their importance, and the use of such plastic products to package cooked food for direct consumption has extremely serious consequences for the health of consumers. Such plastic bags contain a large number of germs that cannot be seen by the naked eye, and long-term use of such disposable plastic food bags can easily lead to chronic food poisoning.

3. At present, most of the film plastic bags used in the early stalls are transparent and inexpensive, and most of them are processed from PVC (polyvinyl chloride) as raw materials, and most of them are recycled materials. The production of recycled plastic bags is the secondary use of plastics, which can save costs, reduce white pollution, and bring great benefits to the environment and society. At the same time, it also greatly facilitates people's lives and is an indispensable item in people's daily life.

However, the use of recycled plastic bags for food is far from the case. This plastic bag, which contains polyvinyl chloride, releases toxic substances such as lead when exposed to high temperatures. When the temperature exceeds 50, the toxic components inside the plastic bag will seep out, thus contaminating the food and causing harm to the human body.

When the temperature reaches 80, it will melt when heated, releasing toxic substances. The temperature of hot (cooked) food is above 40, while the temperature of freshly fried fritters and freshly cooked soy milk is about 90. With the increase of temperature, the activity of toxic substances in plastic bags intensifies, which is easy to be absorbed by food and enter the abdomen of the eater, which will inevitably cause chronic poisoning of the eater for a long time.

The plastic bags that we come into contact with in daily life are made of polyethylene, and the production of plastic bags is inseparable from plasticizers and antioxidants, which will be released with the increase in temperature, generally at 70 80 years ago. And this temperature is precisely the reason why people love plastic bags, just out of the pan of baked cakes, fritters, pancakes are mostly this temperature, a plastic bag can allow us to easily carry high-temperature food, and harmful substances have been quietly released.

Long-term exposure to plasticizers and antioxidants in plastics can cause varying degrees of damage to the liver, kidneys and other organs in the body. The amount of these two preparations will vary with temperature. In other words, the higher the temperature of the food, the more plasticizers and antioxidants are released and volatilized.

The advantage: the cost of the seller is low, and it is convenient to hold. Disadvantages: Ordinary plastic products will decompose harmful toxins when exposed to high temperatures, and the rice is hot, which will react with plastic bags to produce harmful substances, and it is not possible to degrade plastic bags.

The plastic bottom itself is made of garbage, which is not environmentally friendly and unhygienic. Used to hold rice, especially hot, can produce chemicals that are harmful to the body.

Look at the composition of the plastic bag, some of them will produce toxic substances when they are heated, and some are slightly better

The plastic bag itself is not harmful, but it will slowly melt when exposed to heat, and if the rice is hot, it is likely to melt the plastic bag and allow the chemical ingredients to melt into the rice.

Plastic products will decompose harmful toxins when exposed to high temperatures, and rice is hot, which will react with plastic bags to produce harmful substances.

Unhygienic, plastic bags have a lot of bacteria. It is best to come in an eco-friendly box.

The plastic bag that can hold food in the mouth must be a special food bag that meets the food grade standard. However, the cost of this kind of plastic bag is relatively high, and most breakfast stalls do not use it.

It must be harmful, it is recommended to use porcelain products, glass (pay attention to preheating, otherwise it will fry) thermal insulation barrel is also good, aluminum, stainless steel lunch box can also be.
