The words "135 ℃ ultra-high temperature boiling" on the bottle a beverage flagship store
Bottled water is the most simple

In order to pack a unique selling point for such a plain bottle of water, there has been such a type of product in recent years: our water is boiled

For example, one of these products claims to be "boiled at an ultra-high temperature of 135°C", and also says that "cooked water is easy to absorb", which is very advanced and healthy
.
.
Recently, the product sponsored a medical-themed variety show; a group of medical students kept repeating them, making these two claims seem scientifically credible
.
.
But is this really the case?
Ultra-high temperature is not necessary, very common
Let's take a look at one of the promotional points of the product, "135 ℃ ultra-high temperature sterilization"
.
.
First, there is no need to boil the water to this temperature at all
.
.
As a result, the water has no nutrients and is not suitable for bacterial growth
.
.
Second, if tap water is used as the production raw material, the raw material has already been disinfected, and the number of bacteria in it is already very small
.
From the standpoint of eliminating bacteria, even heating is not required: with water purification measures such as reverse osmosis, bacteria can be sufficiently removed

Secondly, "ultra-high temperature sterilization" is not an advanced technology, it is the most conventional processing technology in the food industry
.
For example, normal temperature milk is completely killed by ultra-high temperature sterilization, and then filled into aseptic containers on an aseptic production line
.
The bacteria in the environment can't get in, and they won't grow up, so it can be stored for a long time at room temperature

The process of ultra-high temperature sterilization is also very common

Many small domestic manufacturers can also produce, but the equipment is not as sophisticated as well-known brands
.
Is the boiled water easy to absorb?

Is the boiled water easy to absorb?
This 135 ℃ "boiled water", and another company's "125 ℃ cooked water", both promote the concept of "cooked water is easy to absorb"
.
Although the "mechanism" is not directly explained in the ad copy, we can get a glimpse of it from other marketing articles: small molecular water, better absorption

This isn't a new selling point either
.
However, is small molecular water really better absorbed?

A water molecule is a molecule composed of one oxygen atom and two hydrogen atoms
.
No matter how it is processed, it is impossible to make a water molecule smaller

.
There are real big and small, it is "water molecule group"
.
.
The oxygen atom in one water molecule can attract the hydrogen atom in another water molecule, so that there is a certain attraction between the two water molecules, which is called "hydrogen bond"
.
.
Because of the presence of hydrogen bonds, small clusters of several water molecules appear
.
The stronger the hydrogen bond, the larger the cluster; the weaker the hydrogen bond, the smaller the cluster
.
.
The stronger the hydrogen bond, the larger the cluster; the weaker the hydrogen bond, the smaller the cluster
.
However, the attraction caused by hydrogen bonds is not stable, and the "water molecular clusters" formed based on it are also in an extremely unstable state
.
Temperature has a great influence on the strength of hydrogen bonds.
At high temperatures, hydrogen bonds are weak, so such "water molecular clusters" will be smaller
.
It should be noted here that the "smaller water molecular clusters" only exist at high temperatures, and after heating, the temperature drops to normal temperature, and the normal state is restored

In marketing discourse, such a mechanism is deduced as "the water molecules boiled at high temperature are smaller", and then further deduced as "the water molecules are smaller and easier to absorb"
.
Let's not talk about whether small molecular water is easy to absorb, and whether it is worth drinking 10 sips, just say "small molecular water" is so hot, how to keep warm? How do consumers drink it? Does the water have to be "cooked"?

First define: what we call "cooked water" is boiled water, while raw water is not heated
.
.
In reality, water contains "a variety of impurities" in addition to water molecules
.
For people's health, there are mainly several types of possible harmful substances: toxic inorganic substances, such as mercury, lead, arsenic and nitrite; pathogenic bacteria; some algae that secrete toxins

That's it for water molecules, no matter how big or small
It's not a water moleculeZhanku Hailuo
The "water treatment" we carry out is the process of removing these "harmful substances"
.
In the past, the processing methods that humans could use were very limited, and "heating and boiling" and "cooking" were almost the only feasible methods
.
Its effect is also immediate: firstly, it effectively kills bacteria and solves the safety problem caused by microorganisms; secondly, it can also remove some minerals, thereby "softening the water" to improve the taste
.
However, just boiling does not remove those toxic inorganic substances and heat-stable algal toxins

Today, people have more choices to better sterilize and purify water, such as chlorine compounds, ozone (but the amount of ozone used is a problem, too much will cause carcinogens, and less sterilization is incomplete) and other chemical methods , as well as physical methods such as ultraviolet rays, activated carbon, and reverse osmosis, which can sterilize and remove toxic inorganic substances and algae in water
.
Therefore, "cooked water" in the traditional sense is not necessary for health

In this era, how good is the "cooked water" that advocates "ultra-high temperature sterilization", just like when we travel, we can take a plane, a train, a car, or even a bicycle, which is a better way than walking, but we have to It is indeed a bit ridiculous to advocate that "the pure-blooded BMW imported from abroad can travel thousands of miles a day and 800 nights"
