Microwave oven is a very common fast heating cooking tool. However, there are some precautions for heating in microwave oven. Because tableware will contact with food materials, tableware suitable for microwave heating also needs to be resistant to high temperature. They cannot burn, deform, decompose and release harmful substances at high temperature. There are certain requirements for the thickness and processing technology of the goods. There are some taboos in using microwave ovens, which may lead to safety accidents. So, what tableware is suitable for microwave heating?
1. Ceramic tableware
Underglaze color ceramic tableware is fired at a high temperature of more than 1000 degrees, which is very suitable for microwave heating. Ceramic tableware has high stability, good heat resistance and is not fragile when heated by microwave.
2. Heat resistant glass tableware
The temperature of microwave oven can be as high as 200 degrees. Ordinary glass materials have poor heat resistance and can not be used for high-temperature heating for a long time. Medium and low-temperature heating can be used for a short time. The temperature of heat-resistant glass can be as high as 1000 degrees, mainly including borosilicate glass, microcrystalline glass and titanium oxide crystal glass. In addition, it is best to choose colorless glass to avoid that the colorant in colored glass will contain heavy metals, which may migrate to food during heating and cause harm.
3. High temperature resistant plastic tableware
For example, various utensils made of polypropylene, polypropylene resin, composite polypropylene, polysulfone and other materials can withstand a high temperature of more than 120 degrees Celsius and can be heated in a microwave oven; Secondly, utensils made of PET resin and polyester can withstand high temperatures above 220 degrees Celsius. They can be used not only in microwave ovens, but also in barbecue.
