Why salmon is pink
The flesh of all salmon, irrespective of their origin – farmed or wild – is a pink colour because they consume a carotenoid antioxidant that comes from their diet.
Carotenoids are a naturally occurring group of pigments that pass on colour to the tissue of a variety of organisms. More than 600 naturally occurring carotenoids have been identified in plants and animals – everything from tomatoes to flamingos. They even produce the colours of autumn leaves.
