Many germs can be eliminated by high-temperature disinfection, but there are two conditions that must be met for high-temperature disinfection to be truly effective, one is sufficient temperature, and the other is that it needs enough time. Simply scalding the bowl with boiling water before eating, first, the temperature is not enough, and secondly, the time cannot be reached, so you can only wash the dust on the top and may kill a very small number of microorganisms, and it is useless for most of the curative microorganisms. This has also become a sight to behold in many restaurants.
But can this disinfection method achieve the purpose of sterilization? If you eat out, how can you eat more safely?
<> lasts for 30 seconds, or 55 -60 for 15-30 minutes. Therefore, in boiling water, scalding for more than ten seconds can still kill salmonella. Just like Listeria monocytogenes, it is resistant to cold and heat, and as long as the boiling water is scalded, it can be destroyed.
Most viruses have poor thermal stability, and the DNA of the virus will also unravel the double helix structure at 90 and become a waste virus, but some viruses are relatively powerful, such as hepatitis A virus and hepatitis B virus, which need to last for two minutes under 100 conditions to destroy it. In general, it is fully sterilized by steam, boiling, etc., or it is sterilized with an appropriate disinfectant. Theoretically, such cutlery would be more hygienic.
Because if you don't pay attention to the bottom of the bowl, when the bowls are stacked, the bottom of the bowl on top of the bowl will touch the inner wall of the bowl below, and dirt and bacteria from the bottom of the bowl may enter the other bowl. The maximum heating temperature of the ordinary water heater we use at home is usually set at 75 degrees Celsius - no one dares to pour such hot water on themselves. Samples were taken from the parts of the sample that were most susceptible to bacterial contamination, and the swab was placed into the ATP fluorescence detector for data analysis.
After testing and analysis, the bacterial value on the surface of tableware was 41 RLU, and the surface value of plastic slippers was 246 RLU.
-
It is impossible, it is impossible for these viruses to be eliminated with a single temperature, and they still contain a lot of bacteria, which need to be boiled in hot water for more than ten minutes, or even more than 20 minutes.
-
It can not be completely disinfected, and boiling water should be used to boil the tableware that needs to be sterilized for a few minutes.
In addition, steam and microwave disinfection lamps can be used.
-
Yes, it can be sterilized. Because boiling water can destroy some of our common bacteria, scalding can sterilize his dishes.
-
I don't think so. Because the time of scalding is too short. It cannot achieve the purpose of disinfection and sterilization.
-
Yes, scalding with boiling water can really disinfect, because high-temperature boiling water can kill the bacteria left on the tableware and achieve the effect of disinfection.
-
Of course, because many bacteria can be scalded to death by boiling water, this can make babies eat healthier.

First of all, to disinfect the baby's tableware, the most taboo is to take a variety of disinfectant cleaning agents, even if the rinse is thorough, there will still be chemical residues, affecting the baby's health.
Bao must be cleaned in time after eating to avoid bacterial growth. For tableware disinfection, it is not recommended to use chemicals, such as 84, which will have some residue. If the material of the baby's tableware can be scalded and boiled, then it is a very safe way to disinfect, or put it in the sterilization cabinet for disinfection.
Wash normally under family conditions, and then boil in boiling water for five minutes, if you are outside the restaurant, it is best to bring it yourself before going out, if you don't bring it, then you must ensure that the baby's tableware is fully sterilized from the disinfection cabinet. Nowadays, larger, formal restaurants can do this.
In addition, the proposal of the disinfection of children's tableware has to say that the choice of children's tableware
1. It is best to choose thick porcelain or stainless steel for children's tableware. It is advisable to choose thick porcelain. It's the kind of bone china that is sold in supermarkets that is quite thick to the touch and has a certain weight, not the kind of thin bone china.
Of course, stainless steel is also a choice, stainless steel children's tableware is not fragile and easy to clean, which may be the reason why most parents choose it, but it feels that the environmental performance of thick porcelain tableware is better than stainless steel, although it is fragile compared with stainless steel.
2。The material is selectedOnly then can it be said that the tableware is sterilized。The disinfection of children's tableware can not use any disinfectant, that is, high-temperature disinfection, add water to children's tableware, cover the pot and boil for more than 30 minutes.
The two types of children's tableware selected above are resistant to high temperatures, and are not afraid of cooking or burning. Many parents are accustomed to scalding their children's tableware with boiling water when they take their children out to eat, or disinfect their children's tableware at home, but in fact, the few seconds after boiling water cannot kill bacteria. It is necessary to boil the dishes in boiling water for dozens of minutes to have an effect.
Therefore, parents who have the conditions can buy a dishwasher to clean the dishes, many dishwashers have a disinfection function, and it is also okay to directly buy tools to disinfect children's products.
-
If it is daily disinfection, you can scald it before using it, but this method of disinfection is not very thorough, so you still need to use professional disinfection methods regularly.
-
Before the baby eats, all the baby's tableware is scalded with hot water, which can play a role in sterilization and disinfection; Hot water boiling is very reliable because the high temperature can sterilize.
-
It can be sterilized at high temperature, and it is more reliable to boil it in boiling water, but you must pay attention to the quality of the tableware.

Can you really sterilize dishes with boiling water? On what basis?
First: the temperature of boiling water is usually lower than 100, when the hot water touches the tableware, because the tableware is colder, the water temperature will be reduced accordingly, and the temperature of the disinfection and sterilization effect cannot be reached. In addition, in the process of ironing tableware, it is often only rinsed with boiling water for a few seconds to tens of seconds, which does not reach the time of disinfection and sterilization.
Washing dishes with boiling water before meals can carry away some microorganisms through the water stream, but to achieve the purpose of disinfection, you need to soak in boiling water for 5-10 minutes.
Second: even if the water temperature reaches 100, only 3% of the bacteria on the surface of the dishes can be killed during the washing process. Therefore, the claim that scalding dishes with boiling water can be sterilized is unscientific and strict.
Third: two conditions need to be met to achieve the purpose of sterilization and disinfection of tableware and chopsticks with boiling water: one is to heat and boil until the water temperature reaches 100, and the other is that the scalding time needs at least 5 minutes.
Fourth: among bacteria, Helicobacter pylori needs to be kept at high temperature for 10 minutes, and can be inactivated at 100; E. coli takes 1 minute and can be inactivated at 75 °C; Salmonella typhi takes 15-30 minutes and can be blunted at 70; Staphylococcus aureus takes more than 30 minutes and can be inactivated at 80; Enteroviruses such as rotavirus in the virus can be inactivated by heating in 56 water for 30 minutes, and hepatitis virus can be inactivated by boiling in 100 water for 1 minute; Mold (taking Aspergillus flavus as an example, once it appears, it will produce toxins, which is extremely harmful to the human body) can be inactivated, most of which are below 80, but molds that have begun to produce toxins cannot be inactivated by general physical means; The spores are the dormant bodies of the virus, which are extremely vigorous and difficult to inactivate by general physical methods. 、
In short: washing dishes with boiling water before meals can take away some microorganisms by the water flow, but to achieve the purpose of disinfection, you need to soak in boiling water for 5-10 minutes. Blanching tableware with boiling water does have a certain effect on the disinfection of tableware, but the effect is very small.
It has been suggested that we should start at the source, eat less in places that are not hygienic, or always bring our own utensils.
-
Generally speaking, scalding tableware with boiling water cannot be directly sterilized, and if you want to really disinfect, you should boil it directly with boiling water for about 15 minutes. Therefore, when it comes to meals, it is not necessary to scald the cup with boiling water.
-
It can be sterilized, and some tableware can indeed be cooked with hot water, so that it can indeed be well disinfected and sterilized at high temperatures.
-
Of course, it can be disinfected, and most bacteria cannot survive in a high temperature environment.
