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]
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.
Umami is largely caused by the presence of free amino acids, mainly glutamine and aspartic acid. Sodium from the brine and disodium ribonucleotides from the soy also add to the umami. Other amino acids cause additional basic flavors, with sweet coming from Ala, Gly, Ser, and Thr; bitter coming from Arg, His, Ile, Leu, Met, Phe, Trp, Tyr, and ...

Like modern fermented fish sauce and soy sauce, garum was a rich source of umami flavoring due to the presence of glutamates. [7] It was used along with murri in medieval Byzantine and Arab cuisine to give a savory flavor to dishes. [8] Murri may derive from garum. [9]
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 ]
