"plastic utensils, only polypropylene material, can be used in microwave oven. The heating time of plastic box in the microwave oven the best control in three minutes, time is too long, may not be safe. In addition, it can not be installed oil, oil no more water, oil will be too high, more than 130 ?, plastic ware shape, more than 160 ?, will melt." Dong Jinshi said.
for polypropylene plastic box after high temperature heating will produce carcinogenic substances, Dong Jinshi said, there is no scientific evidence related to. As long as the correct use of microwave ovens, won't appear polypropylene plastic deformation, melting condition. Because the microwave oven is heated by water molecules in food to keep food warming, the boiling point of water at 100 ?, far less than the polypropylene material deformation temperature.
Dong Jinshi think, microwave heating is only physical heating, in the food heating process does not produce chemical changes. "The principle of microwave heating, is the use of friction between molecules, shock, heat, this is like two hands friction fever. The friction between molecules called internal friction, internal friction can produce 3000 times per second concussion, microwave ovens heat from here."
"now no scientific evidence that heating food in microwave oven to be carcinogenic. Dietary carcinogens is nitrite, it is food inside itself,[url=http://rubypage.com/uggboots2013.html]UGG???????[/url], using pot heating will produce, or is in place, may also be because of metamorphic and produce, never mind with microwave heating." [u] International Food Packaging Association Secretary General Dong Jinshi said [/u].

had much electromagnetic radiation experiment test computer, mobile phone, special blower microwave ovens, and other seven kinds of equipment are. The results showed that, the electromagnetic radiation of microwave oven is the biggest, need to stand in the three meters away to avoid radiation. However, the electromagnetic radiation carcinogenesis is still a controversial topic, has not yet been finalized. Although the microwave heating of food not carcinogenic,[url=http://ozsky.org/moncleroutlet.html]??????[/url], however, Sheng food containers through the heating of microwave oven, will produce carcinogenic substances?
can be a container used in microwave oven is divided into three kinds of ceramic, glass and plastic. These three types of utensils, ceramics with high melting point is 3000 ?, glass at 600 ? will begin to soften, carcinogenic maximum, than the lowest melting point of plastic containers.
recently, about the use of heating food in microwave oven to be carcinogenic message let everybody be anxious and fearful, many families have already the microwave oven as a common household appliances indispensable, if use it to heat food may cause cancer, does that mean our health is a huge threat?
