Source of astaxanthin for
Astaxanthin gives the shades of red we see in marine life
like cooked shrimp, lobster and particularly salmon. Natural
astaxanthin is delivered through feeding on migroalgae.
Although astaxanthin itself appears as a red pigment, the light
absorbency can be shifted to result in blue, green, yellow or
brown colours when complexed with various proteins.
environments, phytoplanktons are the primary producers of
carotenoids. Phytoplanktons such as krill, are ingested
by zooplankton or crustaceans and are prey for salmon and
trout. The characteristic red carotenoid – astaxanthin –
is then deposited into their flesh. Ornamental fish
obtain carotenoids from feeding upon algae, coral or prey
that have accumulated these pigments. Astaxanthin in
either complexed or non-complexed form appear to be the
most abundant carotenoids found in all marine animals.
Carotenoids dominate in exoskeletons of crustaceans,
coelenterata and many other marine
