subject: Ten Questions On The Microwave Oven [print this page] When you remove from the microwave steaming, aromatic dishes and snacks overflowing, you may have thought about these issues, perhaps it was also deeply troubled ... ...
1, microwave invisible, intangible, how did they change the food cooked by the students?
We all know, the space around us is full of radio waves of various frequencies. They are widely used in telegraph, telephone, broadcasting, communications, computers, television and other fields, while the microwave is the highest frequency radio waves, so people again called ultra-high frequency microwave radio waves. When heating food in microwave ovens, microwave ovens microwave electric field changes in speed of 2.45 billion times per second, so that the molecular rotation of food, swing frequency is 2.45 billion times per second, elements of high-speed rotation, swing heat generated by mutual friction is very high, that is, the thermal effects of microwave, microwave oven the food is cooked by the students change the truth.
2, microwave cooking food quickly and easily, but the power of hundreds of thousands, is not a great power?
No, the traditional cooking method is to first use of fire heated pan, then transfer the heat from the pot to cook food to achieve the purpose of this pot must consume a large amount of energy, and microwave cooking utensils material with a transmission of microwaves, the microwave transmission through dress food containers, food can be heated directly. Therefore, use of microwave cooking of food, can greatly shorten the cooking time, thereby saving energy. According to experimental proof: Although microwave input power up to 100W or so, but microwave cooking stove cooking food compared with an average time savings of 55%, 40% -50% of the electricity, gas stove cooking more than half of the time average province. For example, a 500W microwave oven cooking with a sauce duck, takes about 15 minutes, the power consumption of only 0.25 degrees.
3, many people think that microwave ovens can cook vegetables, is it?
Not. And microwave cooking of vegetables, vitamin loss than the other methods is much less. Detection of food hygiene supervision departments, according to analysis by microwave cooking cabbage, the loss of vitamin C was 4.76%, while the traditional cooking methods result in the loss rate of 19.04%. In addition, the food of minerals, amino acids exist rate much higher than other cooking methods. Knuckle of pork, such as microwave cooking, microwave heating for the eight essential amino acids in front of 98.6%.
4, some small family kitchen space, then the microwave oven can be moved home in the living room or bedroom as well?
Can, microwave cooking food, no flame, do not smoke, do not heat their own utensils and food in the cooking process does not produce harmful gases, maintaining indoor clean, the microwave oven can be placed in the kitchen can also be placed in the living room or the room. Furthermore, because microwave ovens have regular shutdown protection circuit, so absolutely safe and reliable use.
5, if the microwave to reheat leftovers, how to maintain the original color, shape and flavor?
The most prominent advantage of microwave oven will not change the appearance of food, quality and flavor. Therefore, it can make leftovers Attempt to do me leaves the pot still as delicious when. Reheat food, preferably directly in the original containers to Sheng Cai. Do not plow. As the microwave reheating process is very fast, usually half a bowl of food is only 1-2 minutes, the entire bowl of food no more than 3 minutes.
6, microwave leftovers, can kill bacteria which it?
Can. As we all know, fridge is not safe, cold foods in the refrigerator, some bacteria such as E. coli, Staphylococcus aureus, etc. is also available in which to exist and tenaciously. 1-2 minutes in microwave oven will destroy all the bacteria. Determined by the epidemic prevention station. 500W microwave oven with containing 1,923 / g E. coli sausage processing, 30 seconds remaining 260 / g, 60 seconds to kill all of the same with 1,923 / g E. coli smoked fish processing 30 seconds later survived only 13 / g, 60 seconds after all the killing. Therefore, as a refrigerator microwave abroad have matching products. Microwave oven to kill the powerful capabilities of bacteria, mainly in the microwave output from the two effects, thermal effects and biological effects. Thermal effect as aforesaid, bacterial cell variability of protein heat coagulation, resulting in bacterial death, but refers to the biological effects of low intensity microwave radiation, the organism's temperature has not significantly increased, but the cells of bacteria microwave better than other media, therefore, the rapid breakdown of cells in the microwave oven caused cell death. Normal bacteria in the microwave oven in the lethal temperature is about 70 . The traditional method of high temperature sterilization at least higher than 100 . In this sense, the microwave oven is the guardian of human health, is the symbol of modern civilization.
7, from the gap of the microwave oven can see light or has a trace of wind out of the microwave will thus leak out?
