SALMON
IS GRAY
Salmon is salmon-colored, right? Yes and no.
Most wild salmon get their rosy color from eating crustaceans, including krill and shrimp, which are rich in astaxanthin, a chemical cousin of the carotene pigment.
Farmed salmon, which accounts for at least a third of all salmon now eaten in the world, is a fish of another color. Fed a diet that's not as naturally rich in astaxanthin, their flesh is often pale gray or yellow. To meet consumer color expectations, salmon farmers put color additives, including astaxanthin, into their salmon feed. They've been known to chose how much additive to use from a SalmoFanTM, which is a lot like a paint chip book you might use to pick a shade of color for your house. |
