You might ask, “What is astaxanthin?” Astaxanthin is a red pigment that gives salmon, shrimp, and crab their bright colors. You can find astaxanthin in algae such as Haematococcus pluvialis, as well as in various seafood. The amount of astaxanthin varies in each type of food. Take a look at the table below:
Source | |
|---|---|
Shrimp | 147.7 |
Snow Crab | 119.6 |
Wild Sockeye Salmon | 26–38 |

What Is Astaxanthin
Carotenoid Pigment
You might wonder what astaxanthin is and why it matters. Astaxanthin is a carotenoid pigment. Carotenoids are pigments that give color to plants and animals. Salmon, shrimp, and crab have a bright red color because of astaxanthin. This pigment comes from tiny algae. Marine animals eat these algae and absorb astaxanthin. The pigment spreads in their bodies. It makes their shells and flesh look reddish-orange.
Did you know? Astaxanthin is the main reason salmon and shrimp look so bright. Farmers add astaxanthin to fish food. This helps farmed seafood look like wild-caught seafood.
Astaxanthin does more than add color. It is a strong antioxidant. Its chemical structure has a polyene chain. This chain helps trap harmful radicals inside cell membranes. Astaxanthin protects cells from damage.
Astaxanthin binds inside cell membranes.
It traps radicals and keeps cells healthy.
Pure astaxanthin stays stable for a long time. Inside cells, it can break down faster.
You need good storage to keep astaxanthin stable.
You might ask how astaxanthin compares to other carotenoids. Astaxanthin is more sensitive to ultrasound processing than beta-carotene. Emulsion systems help slow down its breakdown. This keeps its antioxidant power strong.
Natural Sources
If you want to know where astaxanthin comes from, look at algae and seafood. Microalgae make most of the astaxanthin. Fish and shellfish eat these algae. They build up astaxanthin in their bodies.
Here is a table showing the main types of algae that make astaxanthin and their yields:
Algae Type | Astaxanthin Yield (mg/g) | Notes |
|---|---|---|
Haematococcus pluvialis | 38-50 | Can store up to 3.8–5.0% of dry weight as astaxanthin. |
Chlorella zofingiensis | 1 | Yield when grown without light. |
Xanthophyllomyces dendrorhous | 2 | Usually stores less than 0.1% of dry weight, with extra nutrients. |
Haematococcus pluvialis has the most astaxanthin. This microalga can store up to 5% of its dry weight as astaxanthin. Other algae like Chlorella zofingiensis and Xanthophyllomyces dendrorhous make less astaxanthin.
When you eat seafood like salmon or shrimp, you get astaxanthin from algae. This pigment gives these animals their color. It also helps them stay healthy and fight stress. If you want more astaxanthin, look for foods or supplements made from these natural sources.
How It Works
Antioxidant Action
You might wonder how astaxanthin helps your body. Astaxanthin is a strong antioxidant. It fights free radicals. Free radicals are molecules that can hurt your cells. Eating foods with astaxanthin helps your body fight oxidative stress.
Check out the table below to see how astaxanthin works in your cells:
Mechanism | Description |
|---|---|
Free Radical Scavenging Activity | Astaxanthin finds and removes DPPH and galvinoxyl free radicals. This helps stop harmful molecules. |
Singlet Oxygen Quenching | Astaxanthin stops singlet oxygen, which is a dangerous type of oxygen. It keeps your cells safe. |
Induction of Antioxidant Mechanisms | Astaxanthin boosts your body’s own defenses, like paraoxonase-1 and glutathione. |
Astaxanthin is better than many other antioxidants. It works 6000 times better than vitamin C. It is 550 times stronger than vitamin E. It is 40 times stronger than beta-carotene. Astaxanthin gives your cells more protection. It also stops lipid peroxidation much better than vitamin E. This keeps your cell membranes healthy.
Tip: Astaxanthin is not just a pigment. It is a super antioxidant that protects your cells.
