How long does it take to boil boiling water for sterilization, and how long does it take to boil for

Disinfection of boiling water. Normally, 100 meters of boiling water can kill all bacterial propagules after 5 minutes, so it is advisable to boil for 10 minutes for disinfection.

Tableware such as dishes, chopsticks, knives and forks in life need to be disinfected regularly to avoid fungus breeding, usually boiled in boiling water, boiled for about 5 15 minutes after the water is boiled to eliminate the vast majority of fungi. This method is simple, economical and stable.

Boiling water disinfection practices:

The porcelain and glassware in life can be sterilized by boiling water, these objects need to be soaked in warm water at about 60 80 degrees for about 5 minutes, and after the water is boiled, take out the porcelain or glassware and put it in boiling water, submerge the utensils with water, and boil for 5 15 minutes to disinfect and sterilize.

Precautions for boiling water disinfection:

1. Boiling water disinfection needs to ensure that the temperature of the water is 100 degrees, that is, boiling, and the water temperature is too low to be disinfected.

2. Glassware and plasticware need to be preheated in advance to avoid rupture caused by sharp heating, while plasticware cannot be sterilized with boiling water to avoid melting, softening and deformation.

3. It is not recommended to disinfect clothes in daily life with boiling water, and chemical disinfection has the best effect, which can reduce the damage to clothes.

For high-temperature disinfection, the conditions that need to be met are not only high temperature, but also time. Only a certain period of time, a certain high temperature disinfection, can produce results. Specifically, there are two elements:

1. Temperature 100

Common pathogenic bacteria such as Escherichia coli, Salmonella, Shigella, etc., all die at 100 degrees Celsius.

2. The time is longer than 1 minute.

Time is inversely proportional to temperature. At 100 degrees Celsius, it may take 1 to 3 minutes to kill them. If the temperature is lowered, it will take longer. If the temperature is lowered to 56, it may not kill them even if it is heated for an hour and a half.

Choose the right way to disinfect.

1. Bring to a boil. Before eating, put the dishes and chopsticks in boiling water and boil, about 2 to 5 minutes.

2. Steam. When the pot is filled with water and is about to boil, put the dishes and chopsticks on top of it with a stand and use steam to sterilize.

3. Disinfection cabinet.

Buy a special sterilization cabinet, preferably an infrared disinfection cabinet, put the washed dishes and chopsticks in it, set the temperature to 100 120 degrees, and disinfect for 10 20 minutes. Then let it sit for a few minutes, taking care not to burn yourself after the disinfection is complete.

Boil water for sterilization, and boil for 5 to 10 minutes after the water boils.

10 minutes - half an hour is more appropriate.

Cooking is a very simple sterilization method, heating water to 100 degrees and boiling for more than 5 minutes to achieve the purpose of sterilization, which is the easiest disinfection method. This sterilization method is more suitable for natural fiber products, such as towels, metal products such as scissors, hair shears, metal shelves, glass products such as glasses, ceramic products such as porcelain cups, etc.

Boiling water disinfection can only kill most pathogens for at least 15 minutes, and play a role in disinfection and sterilization. Disinfection of boiling water should ensure that the water temperature is 100 degrees Celsius for 15 minutes.

Boiling water to disinfect things, after the water boils, you can boil for ten more minutes, disinfection means that after the thing is disinfected, its practical boiling water can be scalded for a while, help, thank you, about ten minutes.

1. Tableware such as bowls, chopsticks, knives and forks in life need to be disinfected regularly to avoid fungus breeding, usually boiled in boiling water, boiled for about 5 15 minutes after the water bridge is boiled, the vast majority of fungi can be eliminated, simple, economical, and stable. Minxiang.

2 Basic disinfection: boil water for 1 5 minutes.

Bacillus anthracis spores: Boil for 30 minutes.

Tetanus spores: 3 hours.

Botulinum toxin spores: 6 hours.

Alkaline agents such as 1 2% sodium carbonate or soft soap can be added during disinfection, which can dissolve fat and enhance sterilization.

3. The porcelain and glassware in life can be sterilized by boiling water, these objects need to be soaked in warm water at about 60 80 degrees for about 5 minutes, and after the water is boiled, take out the porcelain or glassware and put it in boiling water, submerge the utensils with water, and boil for 5 15 minutes to disinfect and sterilize.

4. Physical disinfection: Physical disinfection is to inactivate fungi and viruses by changing factors such as light, heat, electricity, magnetism, and air pressure in physics. Common ones are: thermal disinfection, mechanical disinfection, radiation disinfection, etc.

Chemical disinfection: Many chemicals have the effect of sterilization and disinfection, mainly related to the acidity and alkalinity, enzymatic effect and oxidation of chemical substances, which can promote the inactivation of fungi. Common chemical disinfection methods are:

Protease disinfection, acid drug disinfection, alkaline drug disinfection, oxidation drug disinfection, etc.

Biological disinfection: biological disinfection is relatively rare, because biological disinfection methods use biological factors to remove pathogens, this method is slow to act, disinfection is not thorough, and it is not recommended for household disinfection.

For tableware, high-temperature boiling is indeed the most common disinfection method, and many germs can be killed by high-temperature disinfection. However, in order to achieve the effect of high-temperature disinfection, two conditions must be met, one is the temperature of the action, and the other is the time of action.

There are many types of microorganisms in enteric-transmitted diseases, and the bacteria that often cause acute diarrhea include pathogenic Escherichia coli, Salmonella, Shigella, Vibrio cholerae, and Bacillus cereus. Most of these bacteria need to be heated by 100 high temperature for 1-3 minutes or 80 for 10 minutes to die, if the heating temperature is 56, these bacteria can still survive after 30 minutes of heating. In addition, certain bacteria have a stronger resistance to high heat, such as anthrax spores, wax spores, etc.

Some people use boiling water to scald the bowl before eating, because the temperature and time of action are insufficient, only a very small number of microorganisms can be killed, and most pathogenic microorganisms cannot be guaranteed.

If you want to use boiling water to achieve real disinfection, you must boil the ribbon for a while, and 5 minutes after the water is boiled.

In addition, the following methods can be used to disinfect dishes:

1. Use steam sterilization, put the washed tableware into the steam cabinet or box, and disinfect it for 5 10 minutes when the temperature rises to 100 degrees.

2. Disinfection cabinet disinfection, the temperature is generally about 120 degrees, and disinfection is 15 to 20 minutes. Nowadays, there are many products such as cupboards with infrared disinfection function in shopping malls, which can also play a role in disinfection and sterilization. However, when purchasing, you need to pay attention to whether the product is qualified.
