Here’s why your farmed salmon has color added to it:
The fact that consumers will shell out more for salmon that looks wild—even if it got that way by eating pellets in its pen—hints that people want to be eating wild salmon, but not quite badly enough to buy the real deal. If it’s price that’s keeping consumers from buying wild-caught salmon, they might want to consider saving a few bucks more and start demanding farmers cut out those expensive pigments—and sell them salmon that’s gray.
[Interesting. But I’d be surprised if it happened. Maybe if a company wanted to take on the marketing of a “new” fish and not call it salmon… and still charge nearly as much. What a mess. (I should add that assuming that none of the folks involved are lying to us, we buy wild salmon, we’re not fans of food coloring.)]
