Can plastic wrap be heated in microwave oven?
It is best not to heat the plastic wrap in the microwave oven.
Ordinary plastic wrap can't be heated in the microwave oven, but microwave plastic wrap can be heated in the microwave oven, but no matter what kind of plastic wrap, it is best to avoid heating plastic wrap in the microwave oven.
Polyethylene or polyvinyl chloride is usually used as the raw material of plastic wrap. The plastic wrap made of these two materials is non-toxic, so it can be used in food and can only be used as packaged food, but it can only be used at room temperature, because these two materials are non-toxic and safe, but they are not resistant to high temperature.
Plastic wrap has its own heat-resistant temperature. For more information, please refer to the tips on the product packaging. So are other plastic products. Different products have different heat resistance, and the heat resistance of plastic wrap is generally between 100 degrees and 180 degrees.
Is it poisonous to put plastic wrap in the microwave oven?
Poor quality fresh-keeping bags and plastic wrap will be toxic if heated in the microwave oven. In the production process of plastic wrap, additives are often added to improve plastic properties and reduce costs, some of which are harmful to human body. Most additives are oil soluble or fat soluble. If the plastic wrap outside cooked food is not removed, additives can easily penetrate into food for a long time, causing pollution.
When microwave heating, do not directly wrap food with plastic film. According to the standard, PVC plastic wrap should be marked with warnings such as "Do not touch greasy food", "Do not heat it in microwave oven" and "Do not use it at high temperature".
Matters needing attention in using plastic wrap
1, holes need to be punched when heating food.
When you cover food with plastic wrap, you should pay attention to pricking several holes in the plastic wrap with toothpicks and other items during the heating process to facilitate the evaporation of water vapor in food. If you don't do this, it will easily lead to gas expansion and plastic wrap explosion, which will lead to danger.
2. Don't bring greasy food.
If the food is greasy, such as fried food, don't use plastic film. Especially in the heating process, the plastic wrap should be isolated from oily food to avoid the food from melting and sticking to the food due to the high oil temperature.
3. Fresh vegetables should not be used for too long.
According to scientific research, fresh seasonal vegetables will lose their nutrients and vitamins after being wrapped with plastic wrap. Therefore, if you want to ensure the freshness of seasonal vegetables, it is best not to eat plastic wrap often, generally not more than 12 hours.
4. Pay attention to the specific difference of high temperature resistance.
Nowadays, various brands of plastic wrap on the market have different high temperature resistance. According to the market survey results, the difference of high temperature resistance of different kinds of plastic wrap is about 65438 00℃. Therefore, we must pay attention to the specific differences of high temperature resistance when choosing.
5. Cooked food and meat food are not provided.
For hot dishes or cooked food, especially meat products, it is best not to store them with plastic film. This is mainly because if greasy meat is wrapped with plastic wrap, the chemical components in plastic wrap will volatilize and dissolve into food, thus causing harm to human body.
