In the wild, salmon get their characteristic hue from the creatures they eat, similar to flamingos. Even as eggs, salmon are pinkish to a reddish-orange. This unique ‘salmon pink’ color reflects this carnivore’s diet of shrimp and krill.
What is the difference between red and pink salmon?
The red salmon flesh color is red while pink salmon is lighter and pinkish. Red salmon weighs about six pounds and spends over a year in freshwater after hatching. Pink salmon weighs about four pounds and goes straight to the ocean after hatching.
Wild salmon is naturally pink due to their diet which includes astaxanthin, a reddish-orange compound found in krill and shrimp. Farm-raised salmon, however, eat whatever farmers throw into their.
Since consumers don’t want gray salmon, farmers feed these fish a supplement called astaxanthin, which gets absorbed into their flesh and makes them pink.
Where does the red pigment in salmon come from?
The red pigment is made by algae and single cell organisms, which are eaten by shrimps; the pigment is then stored in their shell and flesh. When salmon eat shrimps they also accumulate the pigment in their fatty tissue.
Why does salmon turn red when cooked?
In the wild salmon eats lots of crustaceans such as shrimp and krill, which produce a lot of orange-red pigment from the carotenoid family. It’s the same pigment that makes shrimp turn orange-pink when they cook, and a lobster red.
Even as eggs, salmon are a shade of pink or orangish red. The unique color reflects this carnivore’s diet of shrimp and krill. Each species of salmon eats a different proportion of these carotenoid-rich crustaceans, which influences how pink or red they become.
