Choose which lunch box for exclusive use of the microwave oven is good.

Which is the best lunch box? What kind of lunch box is suitable for microwave heating?

There are several types of materials that are safer:

Pots, plates and other utensils made of heat-resistant ceramics are suitable for long-term use in the microwave oven, while ordinary ceramic utensils can only be used for short-term heating. Especially.

1. Plastic material

The plastic lunch box is light and easy to carry. However, after the lunch box of this material is heated in the microwave, it will produce certain toxins, and long-term consumption will cause great harm to people's health. Now there is a kind of PP plastic lunch box on the market, which is not easy to produce harmful substances after high temperature firing, which is safe and reliable.

Ceramic lunch box

Ceramics are divided into heat-resistant ceramics and ordinary ceramics. Lunch boxes made of heat-resistant ceramics are suitable for long-term use in the microwave, while ordinary ceramic lunch boxes can only be used for short-term heating.

3. Glass material

The glass box is the safest, although it is relatively heavy, it has good sealing, and there will be no peculiar smell, and it will not produce harmful substances to the human body. Of course, not all glass materials can be heated in the microwave, and the tempered glass on the market is very good, resistant to high temperatures, and not fragile.

Precautions for buying a microwave lunch box:

1. Tightness.

The bento box is meant to be carried around the room, so it is very important for it to be sealed. Especially when it comes to serving soup, it is even more required to be sealed.

2. Heat retention.

It is also important for its heat retention. Although it is still heated, if it has better thermal insulation performance, I believe that consumers will trust the brand's products more.

1.Glass lunch boxes: include utensils made of borosilicate glass, glass-ceramic, and titanium oxide crystalline glass, but pay attention to the temperature range of high temperature resistance.

2.Ceramic lunch box: There are heat-resistant pottery Zen porcelain and ordinary ceramics.

Eggplant heat-resistant ceramics can be heated for a long time, and ordinary ceramics are not recommended to be heated for too long. In particular, it should be reminded that ceramic lunch boxes containing gold and silver threads should not be used because they will spark when used in the microwave oven.

3.Plastic lunch boxes: all kinds of lunch boxes made of polypropylene, polypropylene resin, composite polypropylene, polysulfone and other materials, with a temperature resistance of more than 120 degrees Celsius, can be used for microwave heating. Hope.

Lunch boxes suitable for microwave heating are usually made of heat-resistant plastic or glass materials. These materials conduct heat quickly and can withstand the high temperatures and heat generated by microwave ovens.

Some of the materials that meet these standards include:

1.Heat-resistant plastics: can withstand the high temperatures generated by microwave ovens and are lightweight and durable. Common heat-resistant plastics include polypropylene, polycarbonate or glass-reinforced polyimide (GRPP).

2.Glass: Glass can withstand high temperatures and does not release harmful chemicals when heated in the microwave. However, glass lunch boxes are usually heavy and fragile, so you need to pay attention to their use and maintenance.

It should be noted that for lunch boxes of any material, it is important to ensure that the lid has been removed before microwaving to avoid accidental damage due to pressure. At the same time, it is also necessary to reasonably adjust the heating time and power of the microwave oven according to the type and size of the food to avoid potential safety hazards.

In general, lunch boxes made of the following materials are suitable for microwave heating:

1.Glass lunch box: The glass lunch box has a better seal to avoid moisture volatilization and make the food taste more delicious, and at the same time, it can withstand high temperatures without deformation or release harmful chemicals.

2.Ceramic lunch box: Ceramic is also a better material for microwave heating because it can be heat-resistant and can better maintain the taste of food.

3.Silicone lunch boxes: The advantages of silicone lunch boxes are that they are resistant to high temperatures, do not contain harmful substances, are easy to clean, and are lightweight and shatter-resistant.

It is important to note that if you are going to heat food in the microwave, it is best not to use materials such as metal, aluminum foil, or plastic bags, as they may cause disasters or smoke. When using a microwave oven to heat food at the same time, pay attention to the time and temperature control to avoid causing safety problems.

In general, except for metal and lunch boxes that are not resistant to high temperatures, most of the materials can be heated in the microwave.

Because of the characteristics of the microwave oven, the metal material cannot be put into the microwave oven to heat food, because the metal is put into the tableware and put it in the microwave oven, it may produce sparks, and in serious cases, it may even appear, so it is not suitable for heating in the microwave oven, and the foam lunch box is not suitable for heating in the microwave oven, because there will be deformation after heating, in addition, basically most of the material lunch boxes can be put into the microwave oven for heating.

When choosing a lunch box for microwave heating, you should choose a material that is suitable for microwave heating.

For example: glass lunch boxes, ceramic lunch boxes, silicone lunch boxes, and special lunch boxes for microwave ovens, the material should be PP, PC and other high-temperature plastics.

The material of the lunch box is very important, some plastic and materials with iron elements should not be put in the microwave because it will melt or produce sparks. Lunch boxes that can be made of glass, ceramic, or silicone are not only safe to put in the microwave for heating, but they also don't have an off-flavored taste of the food. In addition, it is not recommended to use those lunch boxes that do not have a sturdy appearance, as they can easily deform or crack when heated, which is not good for your health and the taste of the food.

In short, when choosing a lunch box, you should take these issues into account in order to have a safer and more convenient hot meal.

The source stool that can be microwaved is the material of the lunch box that needs to master three elements:

The microwave oven has strong penetration, high temperature resistance, and meets the requirements of food hygiene.

Whether the specific lunch boxes of various materials can be microwaved are explained as follows:

1 Glassware: including those made of borosilicate glass, glass-ceramic, and titanium oxide crystalline glass.

Due to the good microwave penetration performance, the physical and chemical properties are stable, and the high temperature resistance (up to 500 degrees Celsius.

to 1000 degrees Celsius), so it is suitable for long-term use in the microwave. Glasses made of ordinary glass、

Hail tremor of milk bottles and nursing bottles should only be heated in the microwave for a short time, about 3 minutes. If it is heated for a long time, it is easy to break. Carved glass, tempered glass, crystal glass products, due to the uneven thickness of the material.

Evenly, it will explode when cooking oily food, so it is not suitable for use in the microwave.

2 Ceramics: There are heat-resistant ceramics and ordinary ceramics. Pots, plates, etc. made of heat-resistant ceramics.

Utensils are suitable for long-term use in the microwave oven, while ordinary ceramic utensils can only be heated for a short time.

Use. In particular, ceramic utensils containing gold and silver threads should not be used because they will spark when used in the microwave oven.

3 Plastic utensils: made of polypropylene, polypropylene resin, composite polypropylene, polysulfone and other materials.

All kinds of utensils can withstand temperatures of more than 120 degrees Celsius and can be used for microwave heating. PET resin, polyester material.

The utensils made of this material can withstand temperatures of more than 220 degrees Celsius and can be used for barbecue.

Plastic wrap is also a plastic product: one is ordinary plastic wrap, which can be used when heating vegetables;

The other is special plastic wrap for microwave ovens, which can be used to heat coarse meat, poultry and sugar foods. As for no.

Heat-resistant polyethylene, styrene, phenol, melamine and other utensils must not be used in the microwave oven, because these materials are microwave-free, and they will melt when heated, and some will emit toxins

Peculiar smell, harmful to human health.

4 Metal utensils: all kinds of utensils made of aluminum, stainless steel, enamel and other metal materials.

The waves cannot penetrate, so the food in them cannot be heated, so it is not suitable for use in the microwave.

5 Wood, paper, and other utensils: In the wet state, these utensils can be used in the microwave for a short time.

However, if it is dried for a long time, the drying of the utensils will lead to super-burning. Painted utensils of this kind are forbidden in micro.

It is used in wave ovens because there is benzene in the paint, and microwave heating can make it emit and contaminate the food.

In addition to paying attention to the material of the utensil, when choosing the shape of the utensil, it is best for consumers to choose a shallow bottom

Wide-mouthed, straight-edged, rounded.
