First, the principle of optical wave furnace
To understand the harm of the wave oven, we need to look at the principle of the wave oven first. At present, there are probably three kinds of wave ovens on the market:
One is the "light wave microwave oven" in which light waves are used as heating sources and microwaves are used to heat food. The shape of the light wave microwave oven is no different from that of the ordinary microwave oven. The principle of the light wave microwave oven is that four devices, namely light source, light wave reflector, light wave control sensor and overtemperature protection device, are added in this light wave oven, and high temperature and high heat can be generated quickly through the light wave tube composed of quartz tube or copper tube, so that the heating effect can be realized quickly.
The second type is called "infrared wave oven", which is basically similar to the traditional induction cooker. The principle of infrared wave oven: using the far infrared heating principle, the heating components in the oven can generate a high temperature of about 500 ~600 degrees in a few seconds after the power is turned on, and then all the heat energy is gathered together by advanced reflective heat-collecting materials, and reflected to the glass-ceramic panel on the furnace surface, which conducts the heat energy to cooking.
The third type is the glass wave oven, also known as the light wave baking pan, which is an upgraded version of the electric oven. Its principle: through the combination of hot cyclone and annular light wave, with the far infrared light wave penetration of the light wave tube, the food is heated three-dimensionally through heat conduction, heat diversion and heat penetration.
Second, the advantages of optical wave furnace
After a period of time, food is easy to absorb moisture and become greasy, and contains high fat. Heating with light wave/hot wave furnace can not only restore the fried dough sticks and oil cakes to their original state, remove greasy, but also greatly reduce the fat content.
2. Reheat the nut food. Moisture regain is a problem that easily occurs after peanut, melon seeds and other nut foods are placed for a period of time, and it has astringent taste and affects appetite. If the microwave oven is used for heating, it can not only remove the astringency, but also restore the crispy and delicious raw material.
3. Reheat snack cookies. High points and biscuits bought in supermarkets or roadside stalls are prone to mildew after a long time. After being stored for a period of time, it can be avoided by reheating them.
4. Reheat meat. The fat content of many meat products is as high as 37%, and the cholesterol is about 0.08%. If the meat products are reheated by light wave/hot wave furnace, not only the original flavor can be restored, but also the fat and cholesterol content can be greatly reduced, which is helpful for middle-aged people to eat.
Third, the use of optical wave furnace
1. A variety of high-temperature resistant containers can be used in the optical wave furnace, but if microwave cooking power is selected, it is best not to use metal or containers with metal. Because the metal can reflect the microwave, it not only makes the food difficult to cook, but also damages the parts of the microwave oven and affects the service life.
2. If you cook frozen food, thaw it first. Attention should be paid to when thawing:
(1) use microwave low-power gear to thaw it evenly;
(2) For some foods with different thicknesses, in order to prevent a part from being cooked, stop thawing first, wrap the thin part with aluminum foil paper, and then continue thawing;
③ The food thawed at one time should not be too much or too thick. The thickness of meat food should not exceed 3 cm, and the thickness of other foods should not exceed 5 to 7 cm.
3. Avoid heating sealed canned and bagged foods with a microwave oven, which may easily lead to the explosion and rupture of sealed products, except for specially marked microwave foods. If plastic wrap is added to the food container to prevent water evaporation, some small holes should be pierced.
4. Avoid frying food in a wave oven. Fried food generally requires slow heating, while light wave and microwave heating are very fast, which is prone to danger.
5. Avoid overtime heating. If the food is thawed or heated in the furnace, if it is forgotten to take it out for more than 2 hours, it should be thrown away to avoid food poisoning.
6. If the time and temperature are not well adjusted, it is recommended not to go away when you first start using the microwave oven. When you see the food turning darker, cut off the power immediately.
7. The most important thing to steam food is to cover it with tin foil or cover the food surface with kitchen treasures. In addition, you need to put a small dish of water on the lower floor, or sprinkle a little water in the stove to increase the moisture.
8. Cleaning of optical wave furnace. It's easy to clean. The base and the glass are separated. After cooking, take out the glass jar and clean it after it cools. It's very simple. Be careful not to wash the burner with water, because the motor is inside the burner, so wipe it with a clean and wet rag.
9. Generally, the light bulb of the optical wave furnace has a service life of 3 years, and the manufacturer can guarantee it for one year. After a long time, the whole furnace body is aging, and it is better to replace it with a new one.
10. Power consumption of optical wave furnace. 7 liters 1000W, 12 liters 1300W, cooking a meal takes half an hour to an hour, and the power consumption is 0.5- 1 degree.
4. Will the food heated by the microwave oven cause harm?
At present, the harm of optical wave furnace is much less than that of ordinary electrical appliances, but it does not mean that there is no harm, but it is relatively reduced, and the harm still exists.
1. Eating light wave food will lead to an increase in the incidence of stomach and intestinal cancer, and at the same time, it will reduce the tissue function of various parts of the body and the function of digestive and excretory systems.
2. Light wave food will produce new toxic and even carcinogenic compounds. In addition to carcinogens, it also produces a bunch of unknown by-products that cannot be absorbed and utilized by the body. This by-product remains in the human body for a long time and permanently.
3. The minerals, vitamins and nutrients in the food cooked by the microwave oven are greatly reduced, which may change into carcinogens and free radicals that destroy the human body, as well as many compounds that cannot be decomposed by the body.
4. Light wave oven food, which destroys brain tissue. The spread of the brain depends on magnetic waves. If the food treated by optical wave furnace is eaten for a long time, it will neutralize the brain magnetic waves, make the brain degenerate and short-circuit the magnetic waves, which is a long-term side effect.
5. Long-term consumption of light wave food can reduce or change the hormone secretion of men and women.
6. Long-term intake of light wave food, because the nutrition has been destroyed, the chemical substances of food components have changed, the lymphatic system will have problems, and the immune system will be reduced, thus reducing the resistance.
7. Metabolic instability in the body caused by light wave food will lead to digestive system disorder.
8. Using light waves to heat meat will reduce the stability of effective protein molecular compounds, and the side effect will produce radioactive pollution in the nearby air and carcinogenic factors in milk and cereals.
9. Long-term consumption of light wave food will cause memory degradation, lack of concentration, emotional instability and reduced understanding. The microwave oven will directly cause the molecules of food to form a new life form called radiation decomposition component, which is not found in natural food.
10. After eating light wave food, the number of white blood cells increased significantly, which shows that some very harmful things have been produced, such as poisoning. In addition, after eating light wave food, the concentration of cholesterol will increase.
