All, Hitting the Delurk tab on my email client, A&P (Anatomy and Physiology) Man comes racing into the fracas to clarify this issue. >There is a difference between flavours and tastes. The FIVE tastes are >sweet, sour, salt, bitter and hot. Flavours are infinite. "Ah, but you forgot one or did it slip by you unnoticed?, Umami! Man, Umami!", sez A&P man, "You are betraying your age!" Umami is the response to salts of glutamic acid — like monosodium glutamate (MSG) a flavor enhancer used in many processed foods and in many Asian dishes. Processed meats and cheeses (proteins) also contain glutamate. "Um...Crispy Doritos, bologna, and Chinese Take-out...kewl!" Dang! I spend too much time running an A&P lab at a community college in here in Queens! Why do I know this!
