What are the umami taste receptors?
The umami taste is often described as a meaty, broth-like, or savory taste, and is independent of the four traditional basic tastes — sweet, sour, salty and bitter. Taste receptors are on microvilli of taste bud in papillae, which are on the rough side of the tongue.
