Question 2: Can bowls and plates used at home be directly heated by microwave oven? Bowls and plates used at home can be heated by microwave oven.
Three taboos of not using microwave oven for heating:
1. Avoid using ordinary plastic containers:
One is that hot food will deform plastic containers, and the other is that ordinary plastics will release toxic substances, pollute food and endanger human health. Use a special microwave oven to hold food and put it in the microwave oven for heating.
2. Avoid using metal appliances:
Because there are iron, aluminum, stainless steel, enamel and other utensils in the furnace, electric sparks will be generated when the microwave oven is heated, which will not only damage the furnace body, but also heat the uncooked food.
3. Avoid using closed containers:
Wide-mouth containers should be used when heating liquid, because the heat generated by heating food in a closed container is not easy to dissipate, which makes the pressure in the container too high and easily leads to blasting accidents. Even if you cook food with shells, you should pierce the shells with needles or chopsticks in advance to avoid bursting after heating, splashing out to pollute the furnace wall or hurting people.
Question 3: What bowl is used for microwave heating? Shopping malls and supermarkets have special prices.
It's like a fresh-keeping box, but it will mark whether the microwave oven is suitable ... not expensive, just a dozen pieces.
If not, you can also use ceramics. There is nothing unusual about using ceramics, but to be honest, I have always doubted whether ceramics will have any chemical effects ... so I always use special equipment for microwave ovens.
But you must never use metal.
Question 4: What bowls can be used in the microwave oven? Bowls made of nonmetallic materials such as glass, plastic and ceramics. Both can be used, but these bowls should be monochrome, so don't draw patterns, because most of the pigments painted on the bowls contain metal components, which will cause sparks when used. According to experts, all metal and enamel containers must not be used in microwave ovens, nor can ceramic utensils with Phnom Penh be used for high-temperature heating. Some of these appliances will damage the microwave oven, some will be very hot after heating, and some will burst if they are not resistant to high temperature, which is very dangerous.
A technician from a microwave oven manufacturer reminded that it is best to use special equipment for microwave heating meals, and it is best to use it with caution for ordinary dishes with colorful patterns. At present, bowls and plates with patterns are divided into over-glaze colors and under-glaze colors. Generally, glazed colored utensils with smooth surface can be used for microwave heating, while glazed colored utensils with rough surface have high lead content and should not be used for heating meals for a long time.
Question 5: What material can microwave ovens use to make bowls? What materials can't be used to make bowls? What kind of utensils are suitable for microwave ovens?
The utensils used in microwave ovens should be made of nonmetallic materials, and never use metal utensils. Microwave oven appliances shall meet the following conditions:
(1) has good microwave transmittance;
(2) Good heat resistance;
(3) Good cold and hot shock resistance;
(4) Meet the food hygiene requirements (including the hygiene requirements under high temperature conditions).
Many non-metallic kitchen utensils commonly used in families can be used for microwave cooking, such as ceramic plates and bowls. If you are not sure whether the nonmetallic kitchen utensils at home are suitable for microwave oven, you can put the utensils in the microwave oven (be careful not to drain water or other things), and then heat them with "high fire" 1 min to check: if the temperature of the utensils is not high and there is no fire in the oven, it means that the utensils have good microwave transmittance, low microwave loss and are suitable for microwave oven use; If the temperature of the vessel itself is high or fire occurs in the furnace (for example, the metal edge on the ceramic bowl may catch fire in the microwave oven), it means that the microwave transmission of the vessel is not good, the microwave loss of the vessel itself is large, and it contains substances that reflect microwaves, so it is not suitable for use in the microwave oven.
(1) Available utensils.
(1) glass cooker. Include glassware made of microcrystalline glass, glassware made of borosilicate, ceramic glass and other heat-resistant materials.
② Ceramic cookware. Fine pottery, coarse pottery and porcelain ware, that is, ordinary ceramic bowls, plates and pots can be used. However, containers with metal decorations may spark or fall off, so please do not use them.
③ Heat-resistant plastic utensils. All heat-resistant plastic utensils are acceptable. But please use heat-resistant glass or ceramic utensils for oily food.
4 stir-fry Microwave cooking is a special utensil for frying and frying. Such as fried steak, fried meat pie, fried steak and so on. The surface of this special container is coated with microwave absorbing material to absorb microwave and make it heat. Food is heated on the surface of the container to produce the cooking effect of frying and frying. In order to use the frying pan better, please read the instructions of the special frying pan carefully.
⑤ Plastic wrap and heat-resistant pe bag. When cooking, it can be used to cover vegetables or cover containers, but it is not allowed to directly wrap meat and fried food.
(2) Do not use appliances.
(1) metal appliances. Aluminum pot, enamel pot, stainless steel pot and other metal containers can't be penetrated by microwaves, so they will collide with the inner wall of the furnace when they touch the metal, so they can't be used. Note that using metal utensils is also easy to damage the microwave oven.
2 lacquerware. The paint on the lacquerware may peel off and melt after being heated, resulting in harmful substances and cracks in the container. Please don't use it.
③ Heat-resistant plastic containers. Ordinary plastic containers have poor heat resistance and cannot be used as cookware in microwave ovens.
④ Heat-resistant glass container. When cooking food with oil, the temperature may be very high and it is easy to break the glass container, so heat-resistant glass containers cannot be used. Organic glassware is also not suitable for use.
⑤ Grass, willow, wood, bamboo and paper products. These containers can be used if heated for a short time, but they may burn if heated for a long time. Please don't use them.
Question 6: Will the special bowl for microwave heating release any harmful substances when it is heated? I suggest that homeowners use special glass bowls or special glassware for microwave ovens. In fact, it is usually dedicated. No matter what material, as long as it is dedicated to microwave ovens, there should be no problem. Have you ever tried it in your life? When you take out the rice while it is hot, the surface of the vessel is not very hot, but the food inside is already very hot. This is the advantage of microwave oven. Of course, as long as the special utensils are professionally processed, they are harmless to the human body. If you are still uneasy, I suggest you use glassware.
Question 7: Can ordinary porcelain bowls be heated by microwave oven? No, there are many dangers. It's best to buy microwave oven equipment in the supermarket. Now there are many beautiful porcelain factories under the ground that can use microwave ovens. I just monopolized a set, which is as expensive as ordinary porcelain.
Question 8: What kind of bowls can't be put in the microwave oven? Anything metallic is not allowed.
It will cause electric spark cutting, which will not only fail to heat, but also damage the microwave oven.
Such as iron bowls, steel bowls, aluminum bowls and tin bowls.
Neither can enamel.
Even ordinary ceramic bowls can't be put into the microwave oven if they are inlaid with metal Phnom Penh.
The special bowl for microwave oven is best made of glass, and ordinary porcelain is also acceptable.
Special reminder: generally, boxed drinks such as milk, soybean milk and fruit juice packaged in Tetra Pak fresh-keeping warehouse should never be put into the microwave oven, because those can only be sandwiched with many layers of tin foil, which can not only be heated, but also burn dangerously!
You'd better pour those things into glass bowls and porcelain bowls.
Question 9: Can ordinary glass bowls be heated by microwave oven 1 hour? If not, then what can be done and what equipment is suitable for microwave ovens? The most important thing is to master three elements: ① microwave oven has strong penetration, ② high temperature resistance, and ③ it meets the requirements of food hygiene.
1. glassware: glassware made of borosilicate glass, microcrystalline glass and titanium oxide crystal glass is suitable for long-term use in microwave ovens because of its good microwave penetration, stable physical and chemical properties and high temperature resistance (up to 500 degrees Celsius or even 1000 degrees Celsius). Glasses, baby bottles and baby bottles made of ordinary glass are only suitable for heating in the microwave oven for a short time, about 3 minutes. If the heating time is long, it is easy to crack. Carved glass, tempered glass and crystal glass products will burst when cooking oily food due to uneven thickness of materials, and are not suitable for use in microwave ovens.
2. Ceramic utensils: there are heat-resistant ceramics and ordinary ceramics. Pots, plates and other utensils made of heat-resistant ceramics are suitable for long-term use in microwave ovens, while ordinary ceramic utensils can only be used for short-term heating. In particular, it should be reminded that ceramic utensils containing gold and silver wires will generate sparks when used in microwave ovens, so they are not suitable for use.
3. Plastic utensils: various utensils made of polypropylene, polypropylene resin, composite polypropylene and polysulfone. , can withstand the temperature above 120 degrees Celsius, and can be used for microwave heating. The container made of PET resin and polyester material can withstand the temperature above 220 degrees Celsius and can be used for barbecue. Plastic wrap also belongs to plastic products: one is common plastic wrap, which can be used when heating vegetables; The other is special plastic wrap for microwave oven, which can be used to heat meat, poultry and sugar food. As for heat-resistant polyethylene, styrene, phenol, melamine and other utensils, don't use them in the microwave oven, because these materials absorb microwaves and will melt when heated, and some will release toxins and odors, which are harmful to human health.
4. Metal utensils: various utensils made of metal materials such as aluminum, stainless steel and enamel. Microwave can't penetrate the bright metal surface and reflect it. The impermeability and reflectivity of metal containers make it impossible for microwaves to reach them and heat food. At the same time, the mutual reflection between the container and the inner wall of the furnace will cause some metals to produce eddy currents and strike a fire, which is very dangerous! Therefore, they are not suitable for use in microwave ovens.
5. Wood, paper and other utensils: In the wet state, these utensils can be used in the microwave oven for a short time. But if it takes a long time, the drying of the utensils will lead to overheating. These painted utensils are forbidden to be used in the microwave oven, because there is benzene in the paint, which will be emitted by microwave heating and pollute the food.
When consumers choose the shape of utensils, they should not only pay attention to the material of utensils, but also choose shallow bottom, wide mouth, straight edge and round shape.
Question 10: What bowl should I use to heat food in the microwave oven? The appliances to be used in the microwave oven should be made of "PE" material (polyethylene), which is the material for food packaging and tableware stipulated by the state and is relatively safe; If you want to use glass and ceramic tableware, you must choose clear ones that can be used in the microwave oven. If there is no clear glass-ceramic tableware, it is easy to break or explode, causing harm.
