چکیده انگلیسی
The ridgetail white prawn (Exopalaemon carinicauda) is an important economic species in China. In order to know the molecular basis and evaluate the potential nutrition value of a new variety of this species with orange-red color, the main carotenoid pigments were extracted and identified through high performance liquid chromatography. It showed that higher concentration of free astaxanthin existed in the new variety which might cause the color variation. The concentration of total astaxanthin in muscle and waste of the new variety was 3.3 and 1.9 fold higher than that in natural prawn under the same culture condition (Pâ¯<â¯0.05). The predominant geometric and optical isomers of astaxanthin in muscle of the new variety were identified as all-trans and 3S,3â²S astaxanthin. This is the first report of astaxanthin-enriched E. carinicauda, which also provides an alternative source of natural astaxanthin and the possibility for improving the nutrition value in this species.
