Umami was first scientifically identified in 1908 by Kikunae Ikeda, [30] [31] a professor of the Tokyo Imperial University. He found that glutamate was responsible for the palatability of the broth from kombu seaweed. He noticed that the taste of kombu dashi was distinct from sweet, sour, bitter, and salty and named it umami. [16]
Kikunae Ikeda (池田 菊苗, Ikeda Kikunae, 8 October 1864 [citation needed] – 3 May 1936) was a Japanese chemist and Tokyo Imperial University professor of chemistry who, in 1908, uncovered the chemical basis of a taste he named umami.
Some common brands of packaged instant dashi. Dashi (出 汁, だし) is a family of stocks used in Japanese cuisine. Dashi forms the base for miso soup, clear broth soup, noodle broth soup, and many simmering liquids to accentuate the savory flavor known as umami. [1]
This is classified as one of the five basic tastes (the word "umami" is a loanword from Japanese; it is also referred to as "savory" or "meaty"). The flavoring effect of glutamate comes from its free form, in which it is not bound to other amino acids in protein. Nonetheless, glutamate by itself does not elicit an intense umami taste.
To determine which glutamate could result in the taste of umami, he studied the taste properties of numerous glutamate salts such as calcium, potassium, ammonium, and magnesium glutamate. Of these salts, monosodium glutamate was the most soluble and palatable, as well as the easiest to crystallize. [ 44 ]
Savoriness, or umami, is an appetitive taste. [13] [17] It can be tasted in soy sauce, meat, dashi and consomme. Umami, a loanword from Japanese meaning "good flavor" or "good taste", [44] umami (旨味) is considered fundamental to many East Asian cuisines, [45] such as Japanese cuisine. [46]
Umami, commonly described as savory, is a marker of proteins and characteristic of broths and cooked meats. [74] Foods that have a strong umami flavor include cheese, meat and mushrooms. [75] Catfish have millions of taste buds covering their entire body.
Umami is one of the five basic human tastes (along with sweet, sour, salty, and bitter). This category is analogous to sweeteners , but instead of the underlying molecules being chiefly glucose or sucrose , these umami sources are all rich in glutamate .
