Gustatory receptors

Patent Granted The gustatory system is the sensory system for the sense of taste. The gustatory system allows humans to distinguish between safe and harmful food. Bitter and sour foods we find unpleasant, while salty, sweet, and meaty tasting foods generally provide a pleasurable sensation. The five specific tastes received by gustatory receptors are salty, sweet, bitter, sour, and umami, which means “delicious” in Japanese.
