Can aluminum foil be put in microwave oven?
Because microwave cannot penetrate metal, it is not recommended to use aluminum foil unless using lighwave baking only. Microwave produces current in inner metal, then the current will form electric arc in the point to cause sparks which is not that dangerous. Any metal products cannot be put in the microwave oven. It is recommended to use light wave stove which has gained a wide popularity in that metal products can be put in it.
Aluminum foil can be used in the microwave oven. Since chicken wing tip, chicken breast or fish head, fishtail or cake edges are easy to overcook, wrapping them with aluminum foil can be helpful to evenly cooking. Tips for microwave oven: 1. Use aluminum foil paper. Since chicken wing tip, chicken breast or fish head, fishtail or cake edges are easy to overcook, wrapping them with aluminum foil can be helpful to evenly cooking. 2. Use vessel cover or fresh-keeping film cover. When cooking or stewing food, to keep the original flavor, prevent evaporation and speed up cooking, vessel cover or fresh-keeping film cover are recommended to use. 3. Use tissue or napkin. Putting a tissue under the food such as baked bread, biscuit, chicken/pork pieces with bread crumbs can keep the food dry and crisp. Covering or wrapping the steamed bun or cakes with wet gauze or tissue can prevent evaporation. 4. Stirring the soup to reset the sliced meat, beefsteak and so on can help improve the cooking. 5. Lay the food aside or add seasoning after heating (for example, add emulsified oil or sauce and then sprinkle chili powder or bread crumbs )can achieve an effect that cooking does not achieve.
No. The microwave produced by the microwave oven belongs to radio wave frequency band and is about 2500MHz. The features of this frequency band are as follows: 1) It can be absorbed by food and water to make the molecular react violently so as to produce heat. 2) It cannot be absorbed by plastic, ceramic and glass. 3) Metal can be conductive to electricity under the influence of the electric field of microwave. Since thick metal can resist the electric field of microwave and reflect microwave, the inner wall of microwave oven is made by thick metal. Similarly, putting a thick metal container in the microwave oven will make the metal container reflect microwave and thus make the food unheated. However, the electric conduction of thin aluminum foil may cause disastrous reaction. In the course of electric conduction, the temperature of thin metal will rise to cause a fire. At the same time, when met with heat, aluminum foil will shrink and its point will produce sparks which may ignite the combustibles in the oven.
