What causes the pink color in cooked catfish?
The pink color in cooked catfish can be attributed to various factors. One of the primary reasons is the presence of a pigment called astaxanthin, which is a carotenoid found in the fish’s diet. Astaxanthin is responsible for the pink or red coloration of many aquatic animals, including salmon and shrimp. When catfish consume food rich in astaxanthin, such as brine shrimp or krill, the pigment is absorbed and stored in their flesh, resulting in a pinkish hue after cooking.
The amount of astaxanthin present in catfish can vary depending on their diet and environment. Farm-raised catfish, for instance, may have a more intense pink color due to their controlled diet, which often includes astaxanthin supplements. In contrast, wild-caught catfish may have a more variable coloration due to their diverse diet and exposure to different environmental factors. It’s essential to note that the pink color does not necessarily affect the fish’s quality, flavor, or safety for consumption.
