Is the flesh of Atlantic salmon naturally red/pink?
Yes, salmon naturally has a red/pink colour, due to an antioxidant called astaxanthin.It is produced in natural waterways by algae, yeast and bacteria which is in the food chain of salmon.
Astaxanthin is an essential nutrient for salmon; salmon require it to remain healthy and disease free.
Salmon are unable to make astaxanthin themselves, needing a dietary supply for these vital functions.
Astaxanthin is made in the same way as for vitamins that you might purchase from a health food shop.
