We know that high temperatures can be decontaminated, so can microwaves that heat up food be decontaminated? It saves time and effort, as well as money to buy disinfectant cabinets。
Suspended
1. The use of home-based microwave stoves for sterilisation is not recommended because of the low quality of the cooking equipment used to disinfect the microwave stoves and the effects of the sterilisation are difficult to ensure。
2. It is recommended that cooking and disinfection cabinets be used to disinfect meals。
The principles of the microwave
Microwave ovens are electrical appliances that use microwave radiation to heat food. Microwave is an electromagnetic wave with a frequency of between 300 and 300,000 mhz and a wavelength of 1 mm-1m. When microwaves encounter water molecules or other polar molecules, they cause rapid oscillation and collisions, generating thermal energy. Thermal energy can heat up food and kill microorganisms. As a result, microwave stoves are widely used in food processing, medicine and pharmaceuticals。
The home microwaves may not be suitable for sterilizing the dishes
Back to the first question, can the home microwave be used to disinfect the dishes
The answer is: it may not be appropriate. There are two reasons for this:
1. There is a low level of utensils suitable for the disinfection of microwave stoves。
Metal products cannot be placed in microwaves because they reflect microwaves, generate sparks and interference. Common plastics are also not allowed because plastics are thermally deformed or release hazardous substances. Only glass, ceramics or plastics marked as high-temperature, microwave-resistant may be placed in the microwave。
The effects of the disinfection of the microwave are difficult to ensure。
The effects of disinfection are influenced by a number of factors, including the type, quantity, tolerance, etc. Of microorganisms, the type, size, shape, water content, packaging, etc. Of the disinfected articles, as well as the size of the microwave, the length of heating time, and the fact that the family microwave is not capable of disinfecting according to professional standards and methods and is therefore likely to fail to achieve the expected effects。
The right way to disinfect the utensils
Sterilization of the dishes, we suggest the following methods:
Boiling method
Put the dishes in the pot, water them, boil them for more than 15 minutes, then dry them or dry them. This approach is simple and effective, but care is taken to prevent burns。
Sterilized cabinets
Select products that comply with national requirements and, strictly in accordance with the instructions of use, wash the dishes and put them in a disinfectant cabinet, select the appropriate mode and time for high temperature or ozone disinfection. This method is easy and fast, but care is taken to keep the disinfectant cabinet clean on a regular basis to prevent bacteria from growing。
In short, microwaves are a good tool for food processing and heating, but they are not a good tool for sterilizing meals。
