Chef's answer
The red colour of tuna flesh is primarily due to the presence of relatively large amounts of myoglobin, an oxygen-binding protein similar to haemoglobin. In the presence of oxygen, the attractive red oxy-myoglobin is dominant, but will degrade during storage to ultimately form brown metmyoglobin.
