Who Identified Umami and When?

Umami was first identified by Japanese scientist Dr. Kikunae Ikeda in 1908. Dr. Kikunae found umami was made of glutamate, an amino acid that was one of the building blocks of protein.

When and how umami was discovered

In 1907, Professor Kikunae Ikeda while savoring a bowl of boiled tofu in kombu dashi (a broth made from a kind of kelp.), he became convinced that there was another basic taste altogether different from sweet, salty, sour, and bitter. Intrigued by this thought, he began analyzing the composition of kombu dashi and by 1908 he isolated crystals that conveyed the taste he had detected. These crystals were made of glutamate—one of the most common amino acids in foods, and in the human body.

By 1909,Ikeda and his partner Saburosuke Suzuki Senior had figured out the means of mass production of this substance, in part by learning how to combine the glutamate with sodium, which is tasty, easy to use as a seasoning, and easy to digest. He had invented monosodium glutamate, MSG. He gave the tas

Dr. Ikeda Discovers the Umami Taste

Dr. Kikunae Ikeda first studied Chemistry at Tokyo Imperial University, before going to further his studies abroad with Professor Ostwald (Nobel Prize Award Winner, 1909) at Leipzig University, Germany. Ikeda then returned to Japan where he became a Professor at Tokyo Imperial University. As well as playing a part in the establishment of basic physical chemistry in Japan, Ikeda was interested in improving the nutrition of the Japanese people. Japan was a developing country at that time and during his studies in Germany, Ikeda observed that Germans had a stronger physique and were taller than the Japanese. The first Japanese doctor of medicine and contemporary to Ikeda, Hiizu Miyake, hypothesized that “good taste stimulates digestion.” This encouraged Ikeda to find the substance responsible for the taste of kelp broth, frequently used in Kyoto where he was born. Ikeda recognized this taste as being common to the taste of the tomatoes and asparagus he ate in Germany for the first time.

With this in mind, Ikeda started research on the

Kikunae Ikeda

19/20th-century Japanese chemist

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. It is one of the five basic tastes along with sweet, bitter, sour and salty.^[1]

Education

Ikeda graduated in 1889 from Tokyo Imperial University in chemistry. In 1891, he became a professor at the Higher Normal School of Tokyo, in 1896 he became an associate professor at Tokyo Imperial University. From 1899, Prof. Ikeda studied in Germany for two years at the laboratory of Prof. Friedrich Wilhelm Ostwald at the University of Leipzig, which was then the center of physical chemistry. After a brief stay in London, he returned to Tokyo in 1901 and became a full professor in chemistry at Tokyo Imperial University.^[2]
