Why farmed salmon is GREY?
But for farm-raised salmon, which makes up 70 percent of the market, color has nothing to do with quality. Farm-raised salmon is naturally gray; the pink color is added. Wild salmon is naturally pink due to their diet which includes astaxanthin, a reddish-orange compound found in krill and shrimp.
Does all farm raised salmon have color added?
How Do Farmers Make Salmon Pink? 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.
Why do they add color to farm raised salmon?
Farmed salmon get astaxanthin in their feeds as an added dietary supplement, hence the use of the phrase “color added”. Asthaxanthin provides color to both wild and farmed salmon flesh, but it is also an important nutrient for the salmon, and for humans. In salmon, astaxanthin is important for growth and survival.

Why is my salmon white and not pink?
White-fleshed king salmon don’t have the genetic ability to break down their food and store the red-orange carotene in their muscle cells. The marbled flesh color sometimes found in king salmon comes from their limited ability to metabolize carotene, causing the flesh to take on a marbled look.

Why is frozen salmon not pink?
Frozen fish often loses its healthy color, even though it’s perfectly good. The culprit: ice crystals.
Is Australian salmon dyed pink?
Wild salmon gets its distinctive pink flesh from a substance called astaxanthin, a pigment found in shrimp-like krill and other crustaceans that the salmon eats. The Four Corners program revealed that farmed fish are often fed a synthetic version of astaxanthin, without which they would be grey or off-white in colour.
Which is better pink or red salmon?

Is discolored salmon safe to eat?
If the skin looks dull and lifeless, or if the flesh has faded to gray, the salmon is probably not fresh. Any dark spots or discoloration are indications of spoilage, as is a milky-white residue on the fillet. (Not the white stuff on salmon you see after it cooks, though; that’s safe.)
What Colour should smoked salmon be?
The salmon should look quite translucent. If it’s very dense in colour, it probably means it’s been frozen, and also that it hasn’t been cured properly, so the water that turned into ice when it was frozen, breaks down the flesh of the salmon when it’s defrosted, and you end up with an unpleasant, mushy texture.
How can you tell the quality of salmon?
Take a good look at the eyes- they should be clear and bright, not sunken or cloudy. The gills should be a deep red and the skin shiny and slippery to the touch. When you pick up the fish it should feel firm, not floppy.
What is the black stuff on salmon?
At the time of slaughter, up to 10-30 per cent of the salmon can show signs of black spots in their muscle fillets. This phenomenon is caused by chronic inflammation sites in the muscles, where cells containing melanin accumulate and give rise to black discoloration.
