Natural Astaxanthin and carotenoids

Research and innovation in Food and beverage industry



Carotenoids are widely distributed in nature comprising plant and animal kingdoms. The colour varies dependent on the lengths of the chromophore and the type of the oxygen-containing groups attached. The carotenoids have in principle two biological functions. They serve as light-harvesting pigments in photosynthesis and they protect against photo oxidative damage caused by active oxygen species such as O2., H2O2 or OH., which are continuously generated in living cells.

Furthermore, carotenoids can absorb photons and transfer the energy to chlorophyll, thus assisting in the harvesting of sunlight.


It is further known that β-carotene, a precursor of astaxanthin, protects against radiation by absorption of energy in the blue region of the light spectrum. It is suggested that β-carotene in the body may protect against cancer and that it also functions as a precursor of vitamin A in mammals so that it is involved in provitamin A activity.



The function of astaxanthin as a powerful antioxidant and a strong inhibitor of lipid peroxidation and has been shown to play an active role in the protection of biological membranes from oxidative injury.


Astaxanthin has a physiological and medical functions and further it plays or may play a role as antioxidant, hormone precursor, in reproduction, in growth and maturation. Because of the powerful antioxidant activity of astaxanthin is the best additive and natural colorants in the human health-food sector. The antioxidant activities of astaxanthin have been shown to be approximately ten times greater than other carotenoids, such as zeaxanthin, lutein, cantaxanthin and β-carotene, and over 500 times greater than α-tocopherol, also known as vitamin E.
