Everyone knows that there are too many types of tableware nowadays. Some people worry that finding inferior materials will not play an ideal role, and there will be more environmental problems. The following introduces whether disposable tableware can be heated in a microwave oven and how to choose tableware. I hope everyone can care about these in the process of selecting materials. The quality of use in the future will be more guaranteed, and there is no need to worry about environmental pollution.
Whether most disposable tableware will melt or not, it is best not to heat it. Some disposable lunch boxes can be heated. Although there are disposable lunch boxes made purely for heating, it is difficult for us to judge whether they can be heated. Therefore, I personally think that as long as there is no label on the lunch box that can be heated, it defaults to non-heating.
Disposable lunch boxes can only be used for light meals and cannot be used twice. The material of disposable lunch boxes is polystyrene, which is easy to melt in a high temperature environment and deforms above 70°C. It is easily corroded by strong acids and alkalis and is not resistant to grease. Easy to change color after being irradiated by ultraviolet rays.
The safety of foamed plastic tableware is related to the pH of the food, whether it contains oil, and temperature. According to national regulations, foamed plastic lunch boxes should be used below 70°C, so it is best to use special microwave heating appliances for safety reasons.
1. Ceramic tableware
Ceramics can be said to be one of the best materials, but in order to make ceramic tableware look more beautiful, some illegal businesses choose some unsafe materials when coloring them. These materials are easy to precipitate after being heated and cause harm to the human body.
2. Stainless steel tableware
Stainless steel tableware has gradually become a big craze for people to buy. Stainless steel tableware is good, but there are certain taboos in its use. We need to pay attention to it all the time.
3. Glass tableware
Clean and hygienic, free of toxic substances. But glass tableware can also "mould" sometimes. This is because the glass is corroded by water for a long time, and the sodium silicate in the glass reacts with the carbon dioxide in the air to form white carbonic acid crystals, which are harmful to human health, so it can be removed with alkaline detergents during use.
4. Plastic tableware
Currently considered safe plastic meals include polyethylene, polystyrene, and polypropylene plastic products. When purchasing and using, you must pay attention to confirm which type of plastic the plastic belongs to. Recycled plastics, plastics with dark pigments and non-food plastics must not be used for holding or packaging food, otherwise, it may be harmful to the human body. Cause poisoning.
The above introduction is whether disposable tableware can be heated in a microwave oven and how to choose tableware. I hope that more people will understand the basic precautions, and then choose high-quality decorative materials to give play to a better advantage without too many problems. In fact, the choice of tableware is quite critical. If you choose inferior tableware materials, it is not particularly ideal, and there may be many usage problems.
