According to media reports, a woman in Guangdong bought a double skin milk at a dessert shop and just scooped it. Before she even put it into her mouth, the double skin milk 'exploded'. The woman's face, neck, The neck was burned and the vision was impaired. The dessert shop owner said that it was due to an erroneous apprenticeship operation that caused the double skin milk to heat in the microwave oven for more than one minute. In fact, it is not uncommon for the microwave oven to cause an 'explosion'. Although it is a good helper in the kitchen, it is easy to accident if you do not pay attention. The following are three principles for the safe use of microwave ovens:
In case of water boiling in the furnace, the heat source is below the water, and the heated water will float to convection. At the boiling point, the water will open. And the microwave heating will not produce convection, but the temperature will rise, and it may exceed the boiling point. It is still not in the “open” state. This kind of overheated water is extremely unstable. If there is a slight disturbance, it will boil violently. If you reach for such overheated water, it is very likely to trigger bumps and the lethality is better than boiling water. The more clean the container and the water, the more prone to accidents. Other liquids, such as milk, soups, etc., are not easily overheated due to the presence of other ingredients, but may 'bump' during the heating process and overflow the container. Doing a mess in the microwave oven. Therefore, use a microwave oven to control the time. Heat the liquid to warm it. Do not use it to boil water.
Anti-explosive. Solid or gelatinous foods. If the surface is fine, the moisture content is high, and there is air inside, it will be easy to explode when heated for a long time in a microwave oven. The most common example is eggs. The eggs have more air inside and the water content is high. , So the heating is fast, the air expands rapidly but it is too late to release, making it in an extremely unstable state. If it explodes in a microwave oven, it only needs to clean the microwave oven at most; but if it explodes after it is taken out, it is equivalent to being in hand. 'Firecrackers' are very dangerous. In addition, ribs, ham and other foods are also easy to explode.
Note that the container releases harmful substances. When heated in a microwave oven, many people pick up any tableware or containers. Plastic or imitation ceramic containers will release small molecules, such as plasticizers, and occasionally do not have much impact. However, long-term exposure to health damage can not be ignored. Especially for foods with high acidity or high fat content, plasticizers are more likely to seep out. In short, if the container does not specifically indicate Microwave heating ', can not be put into the microwave oven. It is best to use only ceramic or glass containers.
