Application
Algae Haematococcus pluvialis serves as a key natural source of astaxanthin, a powerful antioxidant known for its superior ability to neutralize free radicals compared to similar compounds like beta-carotene. Astaxanthin is highly regarded for its potent antioxidant properties, its capacity to inhibit lipid peroxidation, and its anti-inflammatory effects. This naturally occurring pigment is part of the carotenoid group and imparts a reddish hue to foods like salmon and certain crustaceans, such as shrimp and crab. Beyond its dietary presence, astaxanthin is utilized in cosmetics for its antioxidative benefits and potential to offer UV protection. The versatile compound, which can be found both free and as an ester in nature, also functions as a food coloring and plays roles as a plant and animal metabolite.
