Generally, 3~5 minutes is appropriate.

Second, the method of disinfection

1, boiling for disinfection

Put bowls, chopsticks, rags and other tableware in the pot and cook for 3-5 minutes or about half an hour, then take them out to dry. Don't wipe it with an uncooked rag to prevent pollution, and then put it in a clean cupboard.

2, steam disinfection

Put the tableware in the pot, boil water and steam for 5 minutes to achieve the purpose of disinfection.

3, white powder disinfection

Add 2500 grams of water and 65438 0 grams of bleaching powder to form a self-bleaching powder solution. Soak the tableware in this solution for 5 minutes.

3. Can boiling water sterilize tableware?

Disinfection effect is limited: If you want to completely disinfect tableware, you must have two conditions, enough temperature and enough time. Generally speaking, it takes boiling water above 100℃ for more than five minutes to kill most bacteria and microorganisms.

We use boiled water or tea in the restaurant, and it is almost impossible to reach 100 degrees. In order to avoid burns, most restaurants will slightly cool the hot water before serving, and the water temperature is almost only 70-80 degrees. When we iron tableware, we may only iron it for a few seconds or more. Such behavior can't completely disinfect tableware. However, washing with boiling water before eating can still wash away some unclean bacteria and unclean substances. Although the disinfection effect is limited, it is better than nothing.

Fourth, how to disinfect tableware correctly?

1, boiling

The newly bought bowls and chopsticks at home can be cooked in a pot. Put enough water in the pot. After the water is boiled, put chopsticks in a bowl and cook for about five minutes, which can effectively kill most bacteria. However, it is worth noting that wooden chopsticks should not be boiled in boiling water, otherwise they may bend and shorten their service life. Chopsticks must be drained after boiling, and can only be put away after drying, otherwise mold will also breed.

Step 2 steam

As we all know, the temperature of steam is higher than that of boiling water, so we can use steam to sterilize our tableware. After the water boils, put the bowls and chopsticks on it and steam for 2-3 minutes. Steam sterilization can not only shorten the time, but also achieve better sterilization effect. Steam disinfection can be used on wooden chopsticks, and chopsticks will not bend after use.

3. Disinfection cabinet

More than ten years ago, such a sterilizer was popular in the market, which consisted of a water dispenser and a disinfection cabinet. There is also a water dispenser above which water can be heated, and a disinfection cabinet below which tableware can be disinfected. However, it is recommended that you buy a special disinfection cabinet, because professional disinfection cabinets will use infrared rays for disinfection, and the temperature that can be reached during disinfection is about 120 degrees, and the disinfection effect is more thorough.

Tableware can be disinfected by boiling in boiling water for 3~5 minutes, but remember, it must be boiling water above 100 degrees. The correct disinfection methods of tableware include boiling, steaming, disinfection cabinet, white powder and so on. Choose the appropriate disinfection method according to the situation of tableware at home. Do you know how long it will take to disinfect tableware? For the health of family members, we must do a good job of disinfection.
