Regardless of the price, if the average consumer saw two salmon, one that was salmon pink, and one that was jailhouse gray, the pink one will win out most of the time. Not only are the farm raised salmon gray, but all of those omega 3′s we thought we were getting, just don’t occur in similar quantities as they do in wild salmon.
The industry’s solution to this problem was to add a color additive to the salmon to give them a pinker look. As with most food additives, the two that are principally used in salmon are derived from petroleum. Canthaxanthin and astaxanthin are the petrochemicals used to color our fish so it looks pretty and we buy it.
