Canned food was only introduced in modern times in the mainland, but even so, canned food is still popular with mainlanders, and there was a time in the mainland when canned food was almost one of the essential foods in people's homes.
The reason why canned products are popular with people is mainly because the canned food has a good seal, which is not easy to deteriorate and can be easily stored, so that people can solve their appetites when there is no fresh fruit.
However, canned products also have a disadvantage, that is, try to eat the cans in a short time after opening, otherwise the packaged cans are generally not recommended to be stored in the refrigerator after opening.
Even if you store it in the refrigerator, foods such as fruits in canned food can spoil, so relatively speaking, the shelf life of canned products is not particularly long.
But even so, there are still people who often buy canned food to store, and in addition to canned fruits, canned fish, canned meat, etc., there are also very heavy varieties of canned fish and canned meat.
And in addition to these heavy canned foods, there is also a kind of canned food in the Japan that claims to be the world's heavyest, the contents of this canned food are very puzzling, but Japan people are addicted to it, and it is called the "poop" in canned food.
What's going on?
Why do Japan love this canned food while mainlanders avoid it?
So what's in this can?
Canned food.
Canned food has existed since ancient times, but the closed packaging method of canned food is only in modern times.
The name of canned food comes from its outer packaging, that is, the container of canned food, and the name canned food is also the name of this kind of food packaging.
This container was first invented by an United Kingdom man who dated back to 1795 as a method to allow soldiers to eat fresh food on the battlefield.
In the battles year after year, due to limited transportation and other conditions, what is eaten each time will spoil in less than a few days, so in order to allow the soldiers to eat something fresh, this man came up with a solution.
Try to keep the food from being contaminated by bacteria, etc., so that the bacteria cannot break down the food and the food will not spoil.
This method is to seal the food and store it, so that the bacteria will not easily come into contact with the food, the bacteria will not be able to contact the food salad, the food will not be decomposed, and the food will not spoil.
But for the sealed preservation of food, this person has no good way, so he thought of putting the food in a pot for boiling, in this process, if the water in the food is partially evaporated, the food will become relatively dry.
Even if the bacteria come into contact with the food, the water content itself is relatively low, and the bacteria cannot grow quickly, so they will not break down the food.
This man was the prototype of the can, so this man told his soldiers about this method, and the soldiers tried it.
This method proved to be effective, and the soldiers did not spoil as quickly as they used to.
So the method spread and gradually evolved into an industry, and in the 19th century, transportation was greatly improved, and canned food gradually became an alternative to food such as fresh fruit.
But with the progress of time, canned food is still sold in many places, and there is a relatively heavy taste in canned food, even mainlanders are not used to eating it, but this food is produced in Japan.
"Canned poop".
There is a place called Fukuoka in Japan, and the surname here has a tradition of making canned food with a poop flavor since ancient times.
There is a specific factory in this place that makes this canned food, and the canned food it makes has an unbelievable name, which is "canned poop".
The contents of this canned product turned out to be made from human excrement?
After hearing this news, domestic foodies said that they could not accept it, and they did not even dare to look at it, but Japan did not seem to be surprised by this.
Among their cuisine, there is a delicacy called "golden grain meal", in which there is a special type of rice that has an appearance very similar to the shape of a poop.
And the name of this rice in the golden grain meal is called "feces", hence the name "canned stool".
In the early years, there was a Japan who used to make this "poop can".
Making this canned food is actually very simple, just mix the rice and other ingredients such as seaweed, process it, and then put it in the can to seal it.
The outer packaging of poop cans is a yellow wrapper, and the top of the can is a small lid made of aluminum foil.
And the production process of this canned poop is very complicated, there are eight steps in the production process, and one of these eight steps is to make the rice into a poop shape, which is probably why we are not used to eating it.
When we eat, we pay special attention to the shape of the food, which is probably the reason why Japan, who don't care about taste or shape, are not used to eating this "canned stool".
But Japan people are always able to handle some very strange foods deliciously?
Among the delicacies of Japan, there is a delicacy called "cat poop coffee", and the name of this cat poop coffee is also very simple, it is a coffee made by extracting certain components in coffee beans through cat excrement.
So this coffee is called "cat poop coffee", and this cat poop coffee has a great taste, but the price is very expensive, and some people can't accept it when they hear this name.
What's in those stools?
In fact, human excreta contains a lot of water and solid residues, and there are also small amounts of nutrients in solid residues, and there are three main residues in these residues.
One is cellulose, the human digestive system does not digest cellulose, and then takes the fiber out of the body through food, of course, cellulose is not completely devoid of nutrients, but the body basically does not absorb it.
The second is bacteria, bacteria are the things produced by the decomposition of nutrients in the process of digestion and absorption of food, and these wastes are metabolites of bacteria, and they are also useless.
The third is the various mineral components, which contain some minerals in our food, so they are taken out of the body.
But these solid residues don't have any nutrients that can be absorbed by our body, so we just heard that "canned stool" has nutrients in it, so we have a misunderstanding that there are nutrients in it, but it can't.
In our lives, food is digested and absorbed through our body's digestive system, and this process produces some metabolites, which will be excreted by us to form feces.
There are three main components of stool:
Moisture, solid residues, and small amounts of nutrients, mainly fiber, bacteria, and minerals.
In general, about 65%-85% of the weight and composition of stool excreted by adults is water, and the remaining 15%-35% is solid residue.
epilogue
Most of the rumors about the "golden grain meal" are rumors, and there is no real empirical support.
As for the production process of "canned stool", except for the use of stool, the other production processes are no different from the production process of ordinary canned food.
So the contents of the canned poop are not really poop and belong to the gimmick.
As for the production process of cat feces coffee, it is also the coffee essence extracted from cat feces after processing, not the coffee made directly from cat feces.
Therefore, our misunderstanding of these things is often due to our different concepts and cultural backgrounds, which need to be understood.
