Day 21 -- Umami


Umami is the fifth basic taste, in addition to sweet, salty, sour and bitter.

This taste was discovered by a Japanese chemist and professor at the Japanese Imperial University Kikunae Ikeda way back in 1908. 

The research that led to his discovery was the result of a feeling he had that the popular Japanese dish 'kombu dashi' had a taste that didn't exactly belong to the four known tastes. 

This dish is a form of broth made of kelp, a type of seaweed. Finally, Ikeda was able to trace this unique taste to glutamate, an amino acid.

Now umami has been officially recognised by scientists around the world as the fifth basic taste.

What contributed to the official confirmation of umami as the fifth basic taste was the discovery, exactly 20 years ago, in 2002, that there are specific taste receptors in our taste buds that do respond to amino acids.

Amino acids are one of the building blocks of proteins in our body.

Glutamates are commonly found in a variety of food like mushrooms, ripe tomatoes, Chinese cabbage, spinach, cheeses, shrimp pastes, fish sauce, soy sauce, fish, shellfish, etc.

The umami taste is said to be best provided by monosodium glutamate or MSG, a more stable powdered form obtained by adding sodium. Arguably, the most famous commercial MSG-based product is the condiment Ajinomoto. 

MSG has been controversial since 1968 when it was reported that it could be behind certain health issues. A large number of studies have been done, but it hasn't been conclusively proven, though some people do react adversely to MSG.

It is said that one of the reasons why we generally crave for food like cheese and chips with ketchup is the presence of glutamate, and thereby the umami taste.

  1. Suddenly this word has been coming up a lot. Of course, it popped up on a cooking show I like, so I'm not unfamiliar with it now. But it is a recent phenomena.

    Actually, this other level of taste was recognised in western food circles long before 'umami' became the tag-word; it was referred to as the pungency of a dish, a level of depth in flavour.

    I am one who sufferes badly the effects of MSG. It is unnecessary for obtaining umami, but became the short-cut to it and thus dominated food for much of the 60s and 70s and into the 80s. It is one of the key causes of the excessive salt intake of just about all of us on the planet. (Forgive my nutritionist's hat being donned here!!!) YAM xx

  3. I am surprised. I have learned, when in high school, of course in Tamil, that there are 6 basic tastes. Sweet. Sour,salty,bitter,pungent,and astringent.

  4. The taste of mushrooms can be best described as a natural Umami flavour. Oh yes, MSG in large quantities IS harmful. But can that keep us away from the lipsmacking Indo-Chinese cuisine we Indians are so addicted to? Hmmm… :-/

  8. Very scientific post! Very informative. MSG has a bad reputation but it does give a wonderful flavour to foods it is added to.
