Take in the added flavor

Can somebody explain how companies add certain flavored to their food
processing. I can't quite understand the flavor "yellow" as much as
I am struggling to understand the "smoke flavor added" to this. It
reminds me a bit of getting with some skanky chick and when she opens
her legs it smells like the Fulton Fish Market. You don't know what
you are dealing with until your knee deep in carp
I feel like they throw a burnt Marlboro into a can of bumblebee and
call it smoked salmon
