Umami (pronounced oo-MAH-mee) has been called the fifth taste, joining the traditional quartet of salty, sweet, bitter and sour. The word umami derives from the Japanese umai, which roughly translates as deliciousness [source: Umami Information Center]. Chefs have described it as everything from delicate and subtle to earthy, musty and mushroom-like [source: Ninomiya].
Umami, a savory taste, is one of the five basic tastes,. A loanword from the Japanese, umami can be translated pleasant savory taste. This particular writing was chosen by Professor Kikunae Ikeda from umai delicious and mi taste. The kanji æ¨å³ are used for a more general meaning to describe a food as delicious. The human tongue has receptors for L-glutamate, which is the source of umami flavor. For that reason, scientists consider umami to be distinct from saltiness.
