Abstract
Shrimp processing waste is one of the important
natural sources of carotenoid. The major component
of carotenoids of shrimp and crab shell were mono
and diesters of astaxanthin, a very potent antioxidant
with some unique properties. Astaxanthin is a
powerful quencher of singlet oxygen activity and a
strong scavenger of oxygen free radicals. Antioxidant
activity of shrimp shell astaxanthin was
evaluated. The in vitro antioxidant activity of
astaxanthin extract showed significant hydroxyl
radical scavenging activity, superoxide anion scavenging
activity and inhibition of lipid peroxidation.
The IC50 values obtained were 56.43 ± 1.06, 27.91 ±
0.54 and 26.54 ± 0.42 ng ml-1, respectively. Antioxidant
activity of astaxanthin from Aristeus alcocki was
obtained at nanogram levels. This powerful antioxidant
function may be due to the unique molecular
structure of astaxanthin and synergistic effect of
astaxanthin and PUFAs present in the astaxanthin
monoester and diester fractions.
