A taste profile is the what food scientists and marketing people believe divides the world's people taste preferences into neat market segments. For example it is widely regarded as fact amonst the taste profile camp that Americans have a preference for foods which are sweeter, and have a higher fat content-- while Europeans like food that is more salty.

However, not all food scientists and marketers are correct; for evidence of this see the Kit Kat Konspiracy or think back to when Coca Cola changed their formula: only to change it back to, "Coke Classic."
