How many primary taste sensations are there?

Answer 1

There are 5 tastes. The traditional 4 of sweet, bitter, salty, and sour, and a somewhat recently discovered umami. The umami taste is stimulated by monosodium glutamate and is associated with the taste of meat.

The combination of these five tastes cause the unique taste perceptions of various foods.
