Disinfection methods for kitchen utensils mainly include the following:
High-temperature boiling method: Immerse the tableware in boiling water and continue boiling for 5-10 minutes to effectively kill most bacteria. This method is suitable for high-temperature resistant tableware, such as stainless steel bowls and chopsticks, glasses, etc.
Steam disinfection method: Put the cleaned tableware into a steamer or steam cabinet and use high-temperature steam to kill bacteria. Usually, when the temperature rises to 100℃, it takes 5-10 minutes to disinfect. Steam disinfection has the advantages of fast disinfection speed, no pollution, and no damage to tableware. It is suitable for tableware of most materials.
Disinfection cabinet disinfection method: Use a disinfection cabinet for disinfection. Currently, there are three methods of ozone, ultraviolet light, and high-temperature disinfection. After thoroughly cleaning the bowls and chopsticks, put them in the disinfection cabinet and turn on the disinfection. The disinfected tableware can be used directly without washing.
Chemical disinfection method: Use tableware disinfectants approved by the health administration department, such as chlorine-containing disinfectants, to disinfect the tableware by soaking or spraying. When using, it is necessary to dilute it to the corresponding concentration according to the product instructions, and ensure that the disinfectant completely covers the surface of the tableware. After disinfection, be sure to rinse it with clean water and dry it to avoid disinfectant residue.
Microwave disinfection method: Put the tableware in the microwave and use the sterilization ability of microwaves for disinfection. It is recommended to repeat it twice on high heat for 2 minutes (15 minutes between 2 times), or medium heat for 6 minutes. However, it should be noted that metal tableware is not suitable for microwave disinfection.
Ultraviolet disinfection method: Use ultraviolet rays of a specific wavelength to irradiate the surface of tableware to destroy the bacterial DNA structure, thereby achieving a disinfection effect. When using an ultraviolet disinfection cabinet, put the washed tableware in the cabinet, close the cabinet door and turn on the power, set the time and wait for the disinfection to end. However, it should be noted that ultraviolet rays are harmful to the human body and should be avoided from direct exposure when using.
