"Umami or savory taste, is one of the five basic tastes (together with sweetness, sourness, bitterness, and saltiness). It has been described as brothy or meaty. Yes! this is the taste of meat. People taste umami through taste receptors that typically respond to glutamate.
Most of meat's flavor develops when it is cooked. The amount of fat in meat influences its flavor, as does a process called the Maillard reaction. Flavor can also be added to meat through brining and marinating."
