If some readers feel that this article says too many things, too complex, you can use the following jingle to help remember:
To microwave, was No. 5, drink bottles, fast throw away. Do not heat the baby bottle, plastic film to be removed. 7 kinds of different materials, the most important health care.
Live playback 1: Zhang Nan is in college, go home every week is the Internet, hungry to get a instant noodles trouble. Suspected of burning water trouble, give boxed instant noodles with cold water directly into the microwave to cook noodles. One day Grandpa discovered, told him that this plastic box can not be used for microwave heating. Zhang Nan said, microwave lunch box is not what the plastic. Zhang uncle know a little wrong, but can not convince Zhang Nan. Zhang Nan do so in the end right?
Live playback 2: Every morning, Liu Yuan are accustomed to a good breakfast with plastic tableware, cover, into the microwave heating. In order to save time, she put the firepower to the maximum, set the working time of 3 minutes, press the start button, the microwave began to run. What Liu did not know was that his food was being eroded by harmful substances released from plastic.
It is understood that there are many nominal plastic tableware available for microwave ovens, but in fact there is no standard microwave tableware in China, these nominal "can be used for microwave oven" tableware for microwave heating or cooking is not necessarily safe of.
Peking University Health Public Safety Dr. Wen Jie introduced at present, in the market of plastic packaging instant noodles box has two kinds of materials, 5 and 6 plastic, only labeled No. 5 plastic box can be used for microwave ovens. Usually we use a lot of microwave cups, lunch boxes, are made with this plastic. Look at the bottom of the box, if there is a triangle surrounded by the arrow signs, if it is 5, you can use microwave heating, 6 can not.
Market research: special product quality varies
Recently, the reporter conducted a market survey found that the market for sale "microwave for" plastic tableware price confusion, product cohabitation, the quality of worrying, people do not trust.
In a large supermarket, the reporter saw a lot of its sales of plastic cutlery marked in the bottom of the "microwave-specific" words, but did not work the temperature and the proposed use of the time marked the price of these plastic utensils in the 20-50 yuan a. Many of these microwave tableware varieties, but the logo is different, and some marked the use of temperature, use, and some are marked only the use of temperature, and some did not use any instructions.
Experts said: "microwave dedicated" is not necessarily reliable
"Although many tableware are marked 'microwave-specific', but this does not mean that it really applies to microwave ovens." Plastic Association of China Plastic Recycling Committee Vice President, Beijing Dong Jinshi, the Secretary-General said that at present, And did not introduce the relevant standards of microwave tableware.
If marked with microwave-specific plastic tableware, if the price is too cheap, the label is not reliable. If manufacturers use ordinary plastic products to pretend to be microwave-specific plastic tableware, this kind of plastic can not withstand the heat of the grill, it is easy to melt, plastic residue into the food, human consumption will be hazardous to health.
In addition, some manufacturers in order to reduce costs, will produce unqualified plastic products, such plastic products by repeated recycling or by high temperature for a long time heating, will release toxic substances, causing harm to the human body.
Consumption reminder: plastic lunch box is not heating only cooking
The main features of microwave heating, heating is uneven.
Truly can be used for microwave ovens plastic products, the material is polypropylene, polypropylene can withstand temperatures in the 120-130 ℃. However, the temperature of the microwave heating can be more than this temperature, reaching 150 ℃.
Even if it is based on standard testing qualified microwave plastic tableware, it is only recommended in the 700W the following short-term heating conditions, unless the product can be used for cooking or other higher requirements of international certification, can be more stringent conditions .
700W roughly equivalent to the mid-range of microwave ovens firepower, the general manual with the file stalls corresponding to the output power that short-term heating is 2-3 minutes of heating can not be used for cooking cooked food.
