canned herring is a traditional Swedish food, which is a kind of canned food with foul smell and sour taste, which is made by filling the processed herring into cans and letting it naturally ferment.

The biggest feature of fermented herring is its ubiquitous and persistent stench. People who have never eaten pickled herring often cover their noses because of its pungent odor. It is reported that the Swedish government also stipulates that canned herring is not allowed to be opened in residential areas. International flights are also not allowed to carry this kind of canned food, because the change of air pressure may lead to the rupture of canned food, with serious consequences. Its odor is equivalent to 3 times that of natto.

So, if you really want to know how bad it is, Sister Agatha still suggests you buy a can and try it! It takes courage to be fat!

I saw a friend who thought he was a foodie describing canned herring in this way. It was wonderful!

I didn't dare to smell it carefully, but I was going to vomit after a rough smell. I took the courage to taste it. ? _ Gee, it's not as bad as I thought. It's salty. It's like a rotten duck egg being flooded into salted duck eggs. I cann't believe there are fish eggs in it I took two bites, but I didn't dare to eat any more. I felt that my whole mouth smelled bad. At this time, kiss your lover deeply, and you will know if it is true love!

That's probably the smell! Sister Agatha doesn't have the courage to eat!

Besides taste, smell is also an important factor in food flavor.

The unique smell constitutes a unique flavor. Let's feel the canned herring of the Hell brand ~

Canned herring is a traditional "food" in Sweden, but the Swedish government also stipulates that canned herring is not allowed to be opened in residential areas.

At the same time, because the gas produced by the fermentation inside the can may explode and burst the can when heated, many countries have issued relevant bans, prohibiting planes, subways and buses from carrying canned herring and opening the can in public places.

However, even if it is smelly, it is a charming flavor of food.

/The smell of canned herring is not the taste, but the smell/

The canned herring smells bad, but it tastes salty. If someone pinches his nose and eats canned herring, he can reduce his perception of this smell.

it stinks because the impact of the sense of smell is too great ...

Unlike the sense of taste, which mainly senses the nonvolatile chemicals dissolved in saliva, the sense of smell is our perception of the volatile components in food.

The sense of smell is much more complicated and sensitive than the sense of taste.

As mentioned in the previous flavor tweet, our sense of taste can only feel a limited number of flavors, but our sense of smell can distinguish as many as 1, smells, and it is more sensitive.

It is also an ethanol solution, and the concentration we feel by smell is 24, times lower than that we can feel by taste!

when the aroma substances in food aroma enter our nose with the airflow, these odor molecules will dissolve in the mucus on the epithelial surface of nasal mucosa. There is an olfactory receptor at the upper turbinate bone in the deep part of the nasal cavity, and there are many hair-like cilia at the end.

different odor molecules will combine with different receptors on the ciliated membrane, and these feelings are also G protein-coupled receptors.

Just like a key opens a lock, the interaction between specific odor molecules and G-protein-coupled receptors finally depolarizes the cells, so

a nerve impulse is generated and we feel it.

I have to say, the smell comes too fast, just like a tornado ~

/canned herring. What's delicious? /

Why do so many people like this smelly canned herring?

like stinky tofu, smells stinky and tastes fragrant? Is it an experience of "removing the fresh from the smelly"?

Generally, stinky foods are fermented.

During the fermentation, microorganisms will break down these protein into small molecules and amino acids, and

at the same time, they will produce a stinky smell. Because of the high amino acid content, it tastes delicious.

So, can you really feel delicious when you eat canned herring?

in terms of odor, the value of stinky tofu, a famous snack in China, is only 42Au, while the value of canned herring is as high as 87Au, which is almost 2 times that of stinky tofu.

When your eyes and mouth smell 2 times worse than dead mice, it's hard not to hide the delicious taste of food ~

This smell is violent and goes straight to the nose.

However, people who appreciate it will feel that the taste is similar to that of salted durian, and the aftertaste is close to goat cheese and bean curd.

A rich sense of taste actually depends on the sense of smell before and after the nose.

nasal olfaction refers to the process that odor molecules enter the nasal cavity from the nostrils and are perceived by us.

This is easy to understand, but we often ignore the sense of smell behind the nose, which means that after food enters the mouth, odor molecules enter the nasal cavity through the pharynx behind the mouth and are perceived by us.

After food enters the mouth, it is often accompanied by temperature changes, full chewing and chemical reactions involving various enzymes in saliva, which changes the flavor of food. Therefore, the smell felt by the nose after the nose is often very different from that before the nose, which can enrich our sensory experience of food.

So, can you still feel the aftertaste after eating canned herring with your nose between your legs like this?

Although all kinds of "healthy food" and nutritious recipes are popular nowadays, we have to admit that it is the flavor of food that affects our choice and consumption of food to the greatest extent.

Whether a certain food has balanced nutrition and is rich in vitamins and dietary fiber is often vulnerable to whether it is delicious or not.

This does not mean that our perception of food flavor has no nutritional or health value.

For example, our preference for sweetness and umami can make us eat more foods rich in energy and protein, which was very important for human survival in ancient times.

The same sensitivity and aversion to bitterness can help us avoid many spoiled and even poisonous foods.

And the perception of food smell can make it easier for us to find food and avoid toxic substances.

So a long time ago, the flavor of food was not only related to the delicacy, but also related to our survival.

To put it simply, it's like durian. People who like it can't put it down. It's delicious and memorable. People who hate it can't stand its smell and even want to vomit when they see it. The contrast is obvious, but I personally prefer it.
