Scientifically speaking, umami refers to the taste of glutamate, inosinate, or guanylate. Glutamate — or glutamic acid — is a common amino acid in vegetable and animal proteins. Inosinate is mainly found in meats, while guanylate is more abundant in plants 1. Like the other basic tastes, detecting umami is essential for survival. Umami compounds are typically found in high-protein foods, so tasting umami tells your body that a food contains protein.
In response, your body secretes saliva and digestive juices to help digest these proteins 2. Aside from digestion, umami-rich foods may have potential health benefits.
Thus, choosing more umami-rich foods may aid weight loss by curbing your appetite 3 , 4. While most seaweeds are high in glutamate, wakame seaweed is an exception with only 2—50 mg of glutamate per 3. Interestingly, processing and fermenting soybeans raise their total glutamate content, As proteins are broken down into free amino acids, particularly glutamic acid 5. Though soy is controversial due to its phytoestrogen content, eating soy-based foods has been linked to various benefits, including lower blood cholesterol, improved fertility in women, and fewer menopause symptoms 6 , 7 , 8.
As cheeses age, their proteins break down into free amino acids through a process called proteolysis. This raises their levels of free glutamic acid 9. Cheeses that are aged the longest, such as Italian parmesan — which is aged 24—30 months — typically have the most umami taste. These vegetables are fermented with Lactobacillus bacteria, which break down the vegetables by producing digestive enzymes, such as proteases, lipases, and amylases 10 , Proteases break down protein molecules in kimchi into free amino acids through the process proteolysis.
Additionally, green tea is high in glutamate, which is why it has a unique sweet, bitter, and umami taste. Dried green tea contains — mg of glutamate per 3. This drink is also high in theanine, an amino acid that has a similar structure to glutamate. Studies show that theanine also plays a role in its high umami compound levels 17 , Many types of seafood are high in umami compounds.
Seafood can naturally contain both glutamate and inosinate — also known as disodium inosinate. Inosinate is another umami compound that is often used as a food additive Here are the glutamate and inosinate contents for different types of seafood per 3.
Glutamate and disodium inosinate have a synergistic effect on each other, which raises the overall umami taste of foods that contain both Definition of umami Entry 1 of 2. Definition of umami Entry 2 of 2.

Without MSG, my mediocre broth was very mediocre. With it, it was richer and fuller, still vegetal, but with a meaty depth; not different, exactly, so much as better, like an Instagram filter for food. The un-doctored version felt watery by comparison, like it was missing something. Which it was: umami, in the form of MSG.

Sarah Lawrence for Vox As a kindergartener, I was taught there were four basic tastes: sweet, salty, sour, and bitter, which we represented by filling in a map of the tongue with crayon. So how was it identified in the first place? What other foods, besides seaweed, have that umami taste? Do you think of umami as a basic taste?

Dotted over the tongue are patches of tissue called papillae, which contain bud-shaped organs that detect taste. These taste buds, as they are commonly known, consist of dozens of taste cells clumped together. The taste cells in turn contain receptors for sweet, sour, salty, bitter and umami substances. From these receptors, information is transmitted to the brain,and we perceive the taste of the food.
When the receptors in taste cells receive the umami substance glutamate, that information is swiftly passed on to the brain via taste nerves, and umami is recognized. Each of the basic tastes acts as a signal for nutrients or harmful substances.
Umami is the taste of amino acids and nucleotides, and tells us when a food contains protein, a nutrient essential to survival. Recent studies have revealed the presence of umami receptors not only on the tongue, but also in the stomach. When food enters the stomach, and receptors in the stomach detect an umami substance glutamate , the umami information is conveyed to the brain via the vagus nerve.
The brain in turn transmits a message to the stomach that triggers the digestion and absorption of protein. Thus umami is closely involved in protein digestion and absorption, giving it a vital role in our bodies. Throughout history, human beings have created various seasonings and condiments to improve the palatability of food.
Salt has been a familiar flavor-enhancer for thousands of years. Foods such as sugar and vinegar have also been known since ancient times. This is why we can all readily imagine sweet, sour and salty tastes.
Umami too is contained in a variety of foodstuffs, and is familiar to us from the taste of traditional foods such as soy sauce, miso and cheese. However, it is only around a century ago that umami was discovered as a basic taste, and monosodium glutamate invented and launched as an umami seasoning. There were long thought to be just four basic tastes: sweet, sour, salty and bitter.
Then a scientist in Japan? Glutamate extracted from kombu by Professor Ikeda 12 kilograms of kombu yielded 30 grams of glutamate.
Adelicate taste. A mild, subtle taste. A taste that spreads across the tongue, coating it completely. A persistent, lingering taste. This is how chefs who have experienced and recognized umami describe its characteristics. One study had participants separately take solutions of the umami substances glutamate and inosinate, table salt, and tartaric acid the acid component of wine into their mouths, then spit the solutions out and compare the intensity of taste left in their mouth.
While the salty and sour tastes of table salt and tartaric acid soon faded, umami was found to linger for several minutes.
This suggests that even among the basic tastes, umami has a major impact on the aftertaste of foods. Sour or acid taste is widely known to promote salivation, but in fact it has been revealed that umami triggers the sustained secretion of saliva for a longer period.
Furthermore, the saliva produced with sour tastes has a lighter quality, whereas the saliva produced with umami is more viscous, and this seems to moisten more the inside of the mouth. Without saliva we are unable to sense taste or swallow food smoothly.
Umami holds the key to these functions.
