Umami


Definition:

Example Sentences:

  • (1) Umami taste appears to signal, at the gustatory level, the intake of proteins, therefore the working hypothesis was: does umami taste of a monosodium glutamate (MSG) solution elicit changes in both glucagon and insulin release, similar to those elicited by amino acids, and consequently, changes in plasma glucose and in overall cellular metabolism?
  • (2) These results suggest that the gustatory contribution to the flavor denoted by the Japanese word "umami" may be mediated, in part, by neurons that also respond to chemical described by humans as sweet.
