The fifth sense of primary taste.

Umami  is the the fifth sense of primary taste.  (Salty, Sour, Sweet, Bitter and umami) Found and named in JAPAN. It is a pleasant savoury taste from naturally occurring amino acids, and ribonucleotides, including glutamate, inosinate and guanylate, abundant naturally in meat, fish, vegetables and dairy products.

The actual taste of umami is very subtle.  However, you can taste the umami very well with other tastes blending and expanding the flavor rounding out the edge.  It is hard to recognize on its own, but it is a very important factor that makes up the complex nature of taste sensory, to makes up deliciousness.

Umami, was named by a Japanese chemist Kikunae Ikeda.  Deriving from umai “delicious” and mi “taste”. The kanji , reads umami, has been in use in Japan as general term in deliciousness.

We eat using all our senses, sight, hearing, smell, touch and taste to feel the food, but of course actual taste is the most important factor in actually determining the deliciousness of a food.  It was not until 1980’s umami was actually recognized as the fifth primary taste, that conventional four primary tastes, sweet, sour, salt and bitter, cannot replicate umami by any combination of their mixture.

Discovery of the sensory receptor, mGluR4, on taste buds for glutamate has developed the recognition of umami.
