Can tin foil be put in the microwave oven? What is the function of tin foil?

As we know, the original function of microwave oven design is to use electricity to heat food, and with the continuous development and perfection of microwave oven, microwave oven has many functions of cooking or turning raw food into cooked food. In the process of cooking food in microwave oven, people sometimes inevitably use tin foil, which is often used in cooking barbecue food. Many users don't know whether tin foil can be put into the microwave oven, so let's introduce this topic today.

Can tin foil be put in the microwave oven?

If it is used in a large area, it is impossible. If used, because of the high energy of microwave oven, the electrons in metal materials are extremely active. When it reaches a certain level, it will discharge to produce sparks or flashes. Tin foil is also a metal substance, which can also reflect microwaves. If we need to cook food for a long time, we can wrap the easy-to-cook part with a small amount of tin foil.

Relationship between tin foil and microwave oven

Metal and enamel can't be used for cooking utensils in microwave ovens, because metal can reflect microwaves. It not only causes the heating efficiency of microwave oven to decrease and the heating uniformity is poor, but also makes the microwave contact with metal to generate sparks, which is dangerous and even damages the magnetron. Tin foil can reflect microwaves. If we need to cook food for a long time, we can evenly wrap the food that is easy to cook with a small amount of tin foil, and then remove the tin foil after cooking for a while to continue cooking, so that the food can be cooked more evenly. But when in use, the smooth part should be close to the food to reduce the reflected energy. You can use the barbecue function because there is no microwave component.

What is the function of tin foil?

Tin foil is usually used to hold food. When barbecuing, you can wrap the food to prevent it from burning, and sometimes it is used as decoration. Some hair stylists also use aluminum foil to perm their guests. Some people also use aluminum foil to absorb the oil in the soup. Aluminum foil paper is also widely used for insulation, heat exchange and as a conductor. This thin aluminum layer can be waterproof, fresh-keeping, antibacterial and pollution-proof. Usually tin foil is used for heat insulation. For example, you put a glass of water and an ice cube wrapped in tin foil in the microwave oven, and then the water boils, but the ice cube hardly melts.

Above, we introduced some information about microwave ovens. This paper mainly introduces some relations between microwave oven and tin foil. As you can see, we divide this article into three parts to explain. First, in the first part, we introduced whether tin foil can be put into the microwave oven. Actually, it is possible, just don't put it in a large area. Then in the second part of the article, we introduce the relationship between tin foil and microwave oven. Finally, the function of tin foil is introduced for everyone.
