Is it possible to warm food in a bag?
Microwave oven (also microwave oven, microwave oven, microwave oven) is an electrical appliance that uses the phenomenon of heating up water-containing substances with electromagnetic radiation of the decimeter range (usually at a frequency of 2,450 GHz) and designed for fast cooking, heating or defrosting food.
A polyethylene bag is a bag made of polyethylene (polyethylene film) used for carrying and storing things and materials.
Some foods can be heated without removing plastic packaging. On such products and on such packaging there are special signs. However, it is important to remember that when heating, no matter how safe the packaging is, some amount of substances still gets into the food. This figure is negligible, but with prolonged use, harmful substances all the same accumulate in the body and can cause all sorts of diseases.
According to the specialists of the Scientific Center of Hygiene, nothing terrible for the body will not happen, if such a case was single. However, if heating in polyethylene becomes a habit, the harmful substances will begin to accumulate in the body and there will be a certain risk of their poisoning effect on a person.
To warm up food and use cellophane bags for its preparation in a microwave it is possible, but it should be a special cellophane, provided for microwave ovens. For example, cellophane sleeves for baking in the oven are suitable for microwave ovens: this is indicated by the marking on their packaging.
But it is not worthwhile to reheat and prepare food in a standard cellophane package: when heated, the package emits poisonous substances that enter the food, and may even melt. In addition, foodstuffs placed in a hermetically sealed cellophane bag in a microwave oven can explode by staining the microwave.
The basic rule of cooking and warming up food in a specially designed cellophane package is to have a small amount of water in the bag, while it was not hermetically sealed, and the cooking process is not designed for a long period of time.
