Unraveling the Red-Pink Mystery of Astaxanthin in Salmon and Shrimp

Let’s dive into the vibrant world of astaxanthin and its connection to the luscious red-pink hues found in two delectable aquatic delights – salmon and shrimp.

Astaxanthin, a potent antioxidant carotenoid, is not only responsible for the distinct color pigmentation in these aquatic species but also plays a crucial role in their physiological functions and overall health.

The Astaxanthin Powerhouse in Salmon:

Salmon, known for its succulent taste and omega-3 fatty acids, owes its mesmerizing pink-orange color to astaxanthin. In the wild, salmon acquire astaxanthin through their diet, primarily consuming krill and other crustaceans, where this pigment is naturally abundant.

Astaxanthin not only contributes to the visual appeal of salmon but also acts as a shield against oxidative stress, keeping the fish healthy and thriving in their aquatic habitat.

The Astaxanthin Marvel in Shrimp:

Shrimp, another marine delicacy cherished for its sweet flavor, owes its blushing reddish-pink color to the astaxanthin accumulated in their bodies. This pigment is especially concentrated in the shells of shrimp, contributing to their vibrant appearance when cooked.

In addition to adding visual appeal, astaxanthin in shrimp serves as a potent antioxidant, promoting longevity and vitality in these tiny crustaceans.

Misconceptions about Astaxanthin’s Red-Pink Pigment


While apples are known for their vibrant red and green colors, the pigment responsible for this hue is primarily due to compounds called anthocyanins and chlorophyll. Astaxanthin, on the other hand, is not present in apples and does not contribute to their coloration.


Beets are famous for their deep red-purple color, which comes from betalains, specifically betacyanins. Astaxanthin is not found in beets, and its distinct red-pink pigment is separate from the compounds that give beets their color.

Red wine

The lovely red hue in red wine comes from a group of chemical compounds known as anthocyanins, derived from the skins of red grapes during the winemaking process. Astaxanthin, while also red in color, is not present in red wine and does not play a role in its pigment.


Astaxanthin, the powerhouse pigment responsible for the vibrant red-pink hues in salmon and shrimp, is truly a marvel of nature. So next time you indulge in these delicacies, remember the incredible benefits astaxanthin offers for your health and wellness.
