Can hot water really sterilize dishes?

Illness from the mouth is a very common condition. So making the dishes clean is what everyone wants. Boiling water sterilization is also a very common situation.

For example, in the early years, the medical staff on the battlefield used a cauldron to boil to sterilize the bandages in a poor environment, so as to achieve reuse. Therefore, when we use hot water to scald the tableware in order to avoid the disease from entering the mouth, we want to achieve the effect of boiling water sterilization, this practice: to use boiling water to sterilize, we need to meet this condition:

The temperature should be high, and the second is that the time should be long. Boiling water at 100 degrees Celsius, after boiling for dozens of minutes, can kill or inactivate some bacteria and microorganisms. After all, things like bacteria and microorganisms have existed for an unknown number of thousands of years, and they can easily master life-sustaining skills, how can they be so easy to kill?

Most of the hot water for scalding tableware before eating in the restaurant is tea on the table, or boiling water provided by the waiter, with this kind of water: there is not enough time, hot tableware, fast is a few seconds, slow is more than ten seconds, this time, making tea is not enough, let alone sterilization. The temperature is not enough, no restaurant will pour the boiling water to the customers to drink, even if there is boiling water, it is basically not poured, but used to splash In the end, hot water scalding tableware can only play a cleaning role at most, cleaning floating ash or other foreign objects, and can complete this work, cold water is also OK.

Therefore, if you want to ensure the hygiene of the tableware, you need the strict operation and cleaning of specialized personnel, rather than the psychological comfort brought by one or two cups of hot water. If you eat in many fly restaurants, the level of cleanliness of the dishes is probably up to the staff. The only consolation is that, in a way, the problem of cleaning the dishes in the Fly House is nothing.

After all, in comparison, the safety of their ingredients.

Chinese pay attention to temperature when eating. The temperature of the dish is just right, and the plate is cold, and the temperature of the dish will affect the taste. Another example is a bowl of rice, the rice is hot, the bowl is cold, and it is cold when it touches the teeth, which affects the mood of the meal.

Restaurants with conditions will soak the tableware in hot water to warm it, and if there are no conditions, they will use hot water to soak it again. In the past, when the elderly in the family poured water, they would first warm the cup with hot water. Go to a café for coffee, and the coffee cup should be warmed beforehand.

Of course, these are things that are done after the disinfection is done. Hygiene is the first priority, and this kind of attention to living is a further requirement. But for restaurants that can't even do the first step, they use hot water to make dishes to improve the taste.

The purpose of tableware disinfection is to prevent intestinal infections such as diarrhea, stomach pain, cholera, hand, foot and mouth disease. Yes, it's not necessarily bad luck for you to eat out and have diarrhea, friend, it really has a lot to do with the hygiene of the restaurant!! So first of all, let's make it clear that the goal of tableware disinfection is not to sterilize, as long as the pathogens that cause these intestinal infectious diseases are eliminated to the extent that they can't make waves in your stomach.

There are indeed a lot of them that will make you the culprit of intestinal infectious diseases such as diarrhea, such as EV71 and bacteria such as E. coli and Vibrio cholerae, but MRSA, that is, methicillin-resistant Staphylococcus aureus, it doesn't carry this pot!

Scalding dishes with hot water cannot ensure disinfection and sterilization.

In order for high-temperature disinfection to truly achieve the desired effect, two conditions must be met at the same time:

One is temperature and the other is time. Generally speaking, 100 boiling water for more than 5 minutes can kill or inactivate some bacteria and microorganisms. There are many types of microorganisms in enteric-transmitted diseases, and most of the bacteria that often cause acute diarrhea need to go through 100 high temperature action for 3 minutes, or 80 action for 10 minutes before death.

In addition, there are some Vigilant bacteria that are more resistant to high fever.

In order to avoid burns, the hot tea provided by the general restaurant is mostly around 70 80. The water is poured into cold dishes, and the temperature drops to even lower. In addition, when many people iron tableware, it is a few seconds faster and more than ten seconds slowly, which is far from enough in terms of action time.

Therefore, scalding the bowl with boiling water before eating is mostly due to insufficient action temperature and action time, which cannot guarantee to kill most pathogenic microorganisms.

How to dispose of tableware when eating out

First of all, try to go to restaurants that meet the hygiene standards.

Secondly, if you have children, you can bring your own.

Finally, if you insist on ironing the dishes, try to use 100 water for 1-3 minutes or 80 for 10 minutes.

Yes. That is to say, if you can cook the dishes and chopsticks with boiling water for a while, it can play some bactericidal role. The temperature of the boiling water in the restaurant is generally around 60 degrees Celsius, which can no longer play the role of high temperature.

Although Staphylococcus aureus itself does not tolerate high temperatures, toxins are resilient to high temperatures, and it is the bacterial toxins, not the bacteria themselves, that cause food poisoning. So, even if most of the Staphylococcus aureus bacteria are killed, if the utensils have been contaminated with a large number of bacteria, there may also be toxins.

The hot water provided by restaurants is limited, and the time it takes for everyone to iron the dishes does not reach 30 seconds, so the effect of killing bacteria by scalding the dishes may be limited when actually eating. But from other perspectives, hot dishes can still play a certain role in rinsing, such as washing off some dust, residual detergent, etc.

Introduction: Now we all know that disposable tableware is used when eating out, and the tableware is usually sent to a certain disinfection place by the restaurant for cleaning. In the process of using tableware, over time, a lot of bacteria and microorganisms will be produced on the tableware, which will seriously affect the health of individuals.

So can hot water scalding dishes really be sterilized? Let's find out.

As the old saying goes, diseases come from the mouth, and disinfecting tableware can effectively prevent the spread of germs. Well, like tableware is the daily necessities of family life, from the current data shows that in daily life, if not often thoroughly disinfected and cleaned, then these tableware may become the source of transmission of some diseases, especially when the family gets some infectious diseases, because the common use of tableware will cause some intestinal infectious diseases, spread to each other at home, so as a commonly used tableware at home, daily disinfection is conducive to the safety of the family.

Hot water scalding dishes can be sterilized, but the effect is not very good. For the disinfection of hot water dishes, high temperature boiling is a more common disinfection method, because many germs can be killed by high temperature disinfection, and boiling water can not achieve such an effect, only to remove the dust and dirt on the tableware.

You can choose to use high-temperature boiling method to sterilize, put the cleaned tableware into boiling water, you can boil for 2 5 minutes, high-temperature boiling can well eliminate the residual bacteria and harmful substances in the tableware, can help the tableware to keep in a clean and hygienic environment, and it is also a relatively simple disinfection method. Or you can add water to the steamer to boil, and then put the washed tableware into the steamer to steam for about 10 15 minutes, the temperature of the steam is very high, and it can effectively kill the bacteria and harmful substances that may remain on the tableware. Or put the dishes in the oven to heat them up, and they can be sterilized in a few minutes.

It can really be disinfected, because hot water has the effect of disinfection, and it can also help us solve a lot of unnecessary troubles, so I think hot water can really disinfect dishes.

Hot water scalding tableware can be sterilized, hot water can be said to be very high, and the residual bacteria of tableware can play a role in sterilization.

It can really be disinfected, because hot water can kill bacteria and can also help disinfect dishes.

Many people will use hot water to scald the tableware when eating out, because they feel that it is not clean and want to clean the bacteria, its practical hot water scalding the tableware can not achieve the effect of killing bacteria, because if you want to kill bacteria, you also need certain conditions, first of all, the heat of the water should reach between 70-80 degrees Celsius, and then it must continue to be scalded for 5 minutes, and it takes dozens of minutes to kill all bacteria, so it is said that hot water to scald the tableware before meals can not play a role in sterilization.

At most, this is just to clean the obvious dust on the dishes, and it is impossible to kill all the bacteria. Of course, not everyone is unaware of this, and it may also be a psychological comfort, feeling that it is better to flush with boiling water than not at all, so I have developed such a habit. There are also some people who have a sense of ritual, and they always feel that something is missing before eating, so they will keep doing it.

Therefore, in the special period, we should pay attention when we go out to eat, it is best to go to a clean and larger restaurant, so that at least the safety is still guaranteed, don't think about scalding it with hot water, it is best to choose to eat at home, so it is the safest way. Don't leave anything to chance, after all, there is nothing more important than health.

People who used to think that it would be clean after a few scalds with boiling water now know it, and the hot water provided by the hotel is not so hot, after all, it is to be drunk by people, if it is too hot, it may not be able to drink after a meal, it can only be regarded as lukewarm. Even if you go directly to someone's store to drink water, you have to remember that it will work after a long time! This is also the reason why some people now choose to use disposable chopsticks when eating fast food, because they are worried that they will not be clean, after all, it is centralized cleaning.

In the future, if you want to use hot water to flush the dust, you can still use hot water to wash the dust, don't think about using hot water to kill bacteria, you can't do it at all.

Just using hot water to scald the tableware does not have any sterilization effect, but can wash off the dust on the surface of the tableware, if you want to use high temperature sterilization, you need to put the tableware in the hot water and cook for a few minutes.

Its use of hot water to scald the dishes is not effective in killing germs. It has been scientifically proven that only soaking in boiling water at 100 degrees for more than 5 minutes can kill some microorganisms and bacteria. Boiling water to rinse dishes and chopsticks can indeed take away some germs, but because the washing and scalding time is fast, a few seconds and half a minute, because of the lack of time and temperature, the disinfection effect is very limited, after all, the business will also be afraid that the water is too hot to burn the guests and only provide hot water of about 80 degrees.

Yes, but it can only kill a small number of microorganisms, and most viruses cannot be solved.
