"from the Japanese , ""umami"" can be translated as ""pleasant savory taste"". This neologism was coined in 1908 by Japanese chemist Kikunae Ikeda from a nominalization of ""umai"" () ""delicious"". The compound (with ""mi"" () ""taste"") is used for a more general sense of a food as delicious. Scientists have debated whether umami was a basic taste since Kikunae Ikeda first proposed its existence in 1908. In 1985, the term ""umami"" was recognized as the scientific term to describe the taste of glutamates and nucleotides at the first Umami International Symposium in Hawaii. Umami represents the taste of the amino"
"Umami Umami (, from ) or savory taste is one of the five basic tastes (together with sweetness, sourness, bitterness, and saltiness). It has been described as savory and is characteristic of broths and cooked meats. People taste umami through taste receptors that typically respond to glutamate, which is widely present in meat broths and fermented products and commonly added to some foods in the form of monosodium glutamate (MSG). Since umami has its own receptors rather than arising out of a combination of the traditionally recognized taste receptors, scientists now consider umami to be a distinct taste. A loanword"

The types of taste that is generated is divided into five categories sourness, saltiness, bitterness, sweetness, and umami (savoriness). Sourness, which includes hydrogen chloride, acetic acid, and citric acid, is created by hydrogen ions.

Five basic tastes – sweet, sour, bitter, salty and umami (savory) are universally recognized, although some cultures also include pungency and oleogustus (""fattiness""). The number of food smells is unbounded; a food's flavor, therefore, can be easily altered by changing its smell while keeping its taste similar. This is exemplified in artificially flavored jellies, soft drinks and candies, which, while made of bases with a similar taste,"

It can be described as a pleasant ""brothy"" or ""meaty"" taste with a long-lasting, mouthwatering and coating sensation over the tongue. The sensation of umami is due to the detection of the carboxylate anion of glutamate in specialized receptor cells present on the human and other animal tongues. Some 52 peptides may be responsible for detecting umami taste. Its effect is to balance taste and round out the overall flavor of a dish. Umami enhances the palatability of a wide variety of foods.

Umami, or “scrumptiousness”, was first studied with the scientific method and identified by Kikunae Ikeda, who began to analyze kombu in 1907, attempting to isolate its dashi taste. He isolated a substance he called ""ajinomoto"", Japanese for “at the origin of flavor”. His Ajinomoto Co., Inc. currently employs over 32,000 people. ""Ajinomoto"" was later identified as the chemical monosodium glutamate (MSG), and increasingly used independently as a food additive, it is a sodium salt that produces a strong savory taste, especially combined with foods rich in nucleotides such as meats,"

Some population groups, such as the elderly, may benefit from umami taste because their taste and smell sensitivity is impaired by age and medication. The loss of taste and smell can contribute to poor nutrition, increasing their risk of disease. Some evidence exists to show umami not only stimulates appetite, but also may contribute to satiety. Many foods that may be consumed daily are naturally rich in umami components. Glutamate in the form of inosinate comes primarily from meats"
"may occur in one or both ears. Taste receptors (i.e., taste buds or papillae) are activated by the presence of food or another object on the tongue. Four basic tastes include sweet, salty, sour, and bitter. There is some debate on whether umami, or meatiness, is a fifth basic flavor. Aging is associated with loss of intensity in taste. Complete inability to taste is called ageusia. Smells in the external world activate hair receptors in nostrils. These receptors then send signals to the olfactory bulb, which is located at the base of the brain. Anosmia is the inability to smell."

In ""dashi"", L-glutamate comes from sea ""kombu"" (""Laminaria japonica"") and inosinate from dried bonito flakes (""katsuobushi"") or dried sardines (""niboshi""). Most taste buds on the tongue and other regions of the mouth can detect umami taste, irrespective of their location. The tongue map in which different tastes are distributed in different regions of the tongue is a common misconception.

To date, there are five different types of taste receptors known: salt, sweet, sour, bitter, and umami. Each receptor has a different manner of sensory transduction: that is, of detecting the presence of a certain compound and starting an action potential which alerts the brain. It is a matter of debate whether each taste cell is tuned to one specific tastant or to several; Smith and Margolskee claim that"

Perceiving anything beyond these five dimensions, such as distinguishing the flavor of an apple from a pear for example, requires the sense of retronasal smell. Evolutionarily, smell has long been presumed to be a less-important sense for humans, especially compared to vision. Vision appears to dominate human stimuli perception, but researchers now argue that smell cues are highly informative to humans despite being less obviously so. Before his death in"
"sourness enables the control of salt and acid balance. The detection of bitterness warns of poisons—many of a plant's defences are of poisonous compounds that are bitter. Sweetness guides to those foods that will supply energy; the initial breakdown of the energy-giving carbohydrates by salivary amylase creates the taste of sweetness since simple sugars are the first result. The taste of umami is thought to signal protein-rich food. Sour tastes are acidic which is often found in bad food. The brain has to decide very quickly whether the food should be eaten or not. It was the findings in 1991,"
"Of the five basic tastes, three (sweet, bitter and umami tastes) are mediated by receptors from the G protein-coupled receptor family. Mammalian bitter taste receptors (T2Rs) are encoded by a gene family of only a few dozen members. It is believed that bitter taste receptors evolved as a mechanism to avoid ingesting poisonous and harmful substances. If this is the case, one might expect different species to develop different bitter taste receptors based on dietary and geographical constraints. With the exception of T2R1 (which lies on chromosome 5) all human bitter taste receptor genes can be found clustered on chromosome"

There are between 2000 and 5000 taste buds that are located on the back and front of the tongue. Others are located on the roof, sides and back of the mouth, and in the throat. Each taste bud contains 50 to 100 taste receptor cells. Bitter foods are generally found unpleasant, while sour, salty, sweet, and umami tasting foods generally provide a pleasurable sensation.

The five qualities of taste detected by the tongue include sourness, bitterness, sweetness, saltiness, and the protein taste quality, called umami. In contrast, the term ""flavor"" refers to the experience generated through integration of taste with smell"

The optimum umami taste depends also on the amount of salt, and at the same time, low-salt foods can maintain a satisfactory taste with the appropriate amount of umami. One study showed that ratings of pleasantness, taste intensity, and ideal saltiness of low-salt soups were greater when the soup contained umami, whereas low-salt soups without umami were less pleasant. Another study demonstrated that using fish sauce as a source of umami could reduce the need"

In 2015, researchers suggested a new basic taste of fatty acids called fat taste, although oleogustus and pinguis have both been proposed as alternate terms.

The olfactory system recognizes the odorants as they pass to the olfactory epithelium via a retronasal pathway.

The overall flavor of soy sauce is a result of the balance and interaction among different taste components. The saltiness is largely attributed to the presence of NaCl in brine. The sugars hydrolyzed from starch add sweetness into soy sauce. Umami is largely caused by the presence of free amino acids. Besides, the interaction between glutamine and sodium cation may have given rise to sodium glutamate (MSG), which can further contribute to the umami flavor. Basic tastes"
