👉 Biliverdin Explained
The lingcod gets blue meat due to a natural pigment called biliverdin. This pigment is responsible for the blue color of lingcod meat. Biliverdin is a bile pigment produced when red blood cells break down. In most animals, it’s processed and removed. But in lingcod, biliverdin accumulates in muscle tissue, giving the meat a blue or greenish color. Now lets know more about biliverding.
This pigment:
