WebAug 19, 2015 · Tastants are sensed by taste buds, which constitute taste cells on the tongue. Humans are able to detect 5 basic tastes: bitter, sweet, umami, sour, and salty. Sensing sour and salty is mediated by ion channels, whereas sweet and umami are sensed by the taste receptor type 1 family, and bitter triggers the taste receptor type 2 family ( 1 ). WebSour tastants are acids which belong to the thermoreceptor protein family. Binding of an acid or other sour-tasting molecule triggers a change in the ion channel which increases hydrogen ion (H +) concentrations in the taste neurons; thus, depolarizing them. Sweet, bitter, and umami tastants require a G-protein-coupled receptor. These tastants ... Web新規な風味、風味改質剤、味覚剤、味覚向上剤、旨味および甘味味覚剤、および／またはそれらの向上剤および使用 - 特許庁. 例文.
