Do you know why sauce made from chemical seasonings dissolved into soy sauce is used for sushi that commoners eat?

There is a sensor on the tongue that feels the degree of saltiness. This prevents us from eating too much of things that are extremely salty. Chemical seasonings confuse that sensor. The chemical seasoning palliates the degree of saltiness felt by the tongue. Even if you were to, for example, dunk your sushi into the soy sauce and chemical seasoning mixture, it won’t feel salty. If you eat sushi with the sauce, you can take in a high volume of sodium, which is a pleasure trigger for the human body, without feeling the saltiness on your tongue. In other words, it may be more accurate to say that with commoner sushi, you actually drink the sauce, not dip into it.

Why is sushi eaten with soy sauce?

Edo style sushi was created during the Edo period in Japan (1804-1830). The expansion of the soy sauce culture of the Edo area (currently Tokyo) had a big influence on the creation of Edo style sushi. In a time when refrigeration and other technology had not yet been developed, soy sauce played an important role not only in taste, but also in preservation. A surprising number of tasks in the Edo style utilize the scientific effects of soy sauce.

First of all, by lightly boiling down the topping, bringing out its flavor and creating a glaze. To put it scientifically, this a clever use of the odor eliminating effects of soy sauce, eliminating the raw odor.

 

Also, long ago zuke (soaking in soy sauce) was also used for fish other than tuna. This was a way to utilize the bacteriostatic effects of soy sauce, which stop the growth of Escherichia coli (E. coli).

 

Boiling down (tsume) represents the thermal effects of soy sauce. By adding soy sauce, mirin and sugar then boiling down, the amino acids in the soy sauce and the sugar react and the goal is to create a delicious glaze and a nice scent that stimulates the appetite.

Adding a small amount of soy sauce when making rolled egg omelets has the effect of enhancing and bringing out the flavor and sweetness of the ingredients.

Soy sauce is generally overshadowed by the sushi topping and vinegar rice, but soy sauce plays an important role in bringing out and enhancing the delicious taste of the sushi.
