Why Salmon is Pink?




Salmon is a freshwater fish that can be easily distinguished due to its pinkish color when looking from the outside. Ranging from orange to ivory-pink, flesh color is a result of the carotenoids, which are organic pigments produced by plants, algae, and several bacteria.

Xanthophylls (originally phylloxanthins) are a group of pigments that occur widely in nature and form one of two major divisions of the carotenoid group. Astaxanthin is a xanthophyll carotenoid, which gives salmon its pinkish color.
