Ever wonder what makes Japanese food taste the way it does? It absolutely has a very distinct flavor, but how would you describe it?

A hundred years ago, the distinct flavor of Japanese food lead to the discovery of a brand new flavor: umami.

The Four Basic Tastes

If you want to describe the taste of your food, then you probably use a combination of a few different words: sour, bitter, salty, and sweet.

And in fact, for thousands of years people have used those four concepts to describe their food. Sure, you might branch out a little bit more by describing the textures (e.g. crunchy, tender) or compare it to another food, but at the very core, there wasn’t any other way to describe taste.

Why? Mainly because of this guy:

Hey kids! Stay in school!

This guy’s name was Democritus. Democritus, along with a bunch of other Greek thinkers like Socrates and Euclid, were pretty much the founders of western scientific and philosophical thought.

And Democritus theorized that foods tasted like one of the four basic categories because of the shapes of the food’s atoms.

To be fair, Greek thinkers got a lot of things right (like geometry!). On the other hand, they were wrong about a lot of other things (like leeches!).

And Democritus couldn’t be more wrong about the number of basic tastes. But nobody would challenge the scientific basis of this claim until thousands of years later, when an unknown Japanese scientist started questioning the status quo.

The Fifth Basic Taste

In the early 1900s, a Japanese chemist named Kikunae Ikeda began to wonder if there might be a fifith basic taste. After examining lots of different foods that didn’t quite fit into the four other categories, Ikeda found it: the fifth taste.

He called it umami (うま味). Some cultures call it savoriness, but the term umami is used all across the world today.

What is umami exactly? It’s a little hard to describe. Umami is the kind of flavor that’s found in meat, cheese, and mushrooms. Again, think “savory.”

And not only did Ikeda discover umami, but he also created monosodium glutamate, or MSG.  So whenever you’re in a cheap Chinese restaurant that heaps on the MSG, thank Ikeda.

The Science of Taste

Why do things taste the way they do? How did Ikeda discover umami? It’s all in the science of food. (And no, I’m not talking about molecular gastronomy.)

There’s actually a scientific explanation behind each type of taste. Sourness, bitterness, saltiness, sweetness, and umami all have a chemical linked to them that make them taste the way they do.

For umami, that chemical is glutamate. Ikeda was able to figure out that all of the foods that had the umami flavor all had high levels of glutamate.

Why Japan?

 

How was umami discovered in Japan, of all places? Look into Japan’s history and it seems almost obvious.

Buddhism values all life, which is why Buddhist practitioners are sometimes vegetarian. So when Buddhism was first introduced in Japan way back in the day, meat was formally banned for a time.

Obviously, this ban wasn’t too long-lasting or always observed, but it did have some impact on Japanese food. To compensate for the lack of meat, Japanese developed a cuisine with lots of food rich in umami. Most of the foods that are the foundation of Japanese cuisine, like dashi and soy sauce, are very umami-heavy.

    Check out Wikipedia though: http://en.wikipedia.org/wiki/Savoriness
    Savoriness redirects to Umami. Though it does say that it is popularly referred to as savoriness.

    my friend fed his dog with an enormous amount of “aji-no-moto”  monosodium glutamate, the next day it died. SAd T_T

    Yes, but what about spicy?

  • ZXNova

    Spicy isn’t really a taste, but rather a sensation. Cause of that you can have Spicy-Sour, Spicy-Sweet, Spicy-Bitter, Spicy-Salty, and Spicy-Umami (Savory). Spicy is just simply a sensation.

    lol You cant compare like that. Because savory is real English base. So it’s used in many type of sentence, not only about type of food taste.

    I don’t think I’ve ever heard the word umami before this article, so at least in my realm of experience that seems true… though I also don’t watch food channel or anything like that.

    I’ve only ever heard savory refer to food.
