Abstract
Antarctic krill (Euphausia superba) is typical of a enormous biomass of marine zooplankton that could provide good nutrition in human body. This study was conducted to identify the nutrition of krill, a live in Antarctic Ocean. The analysis result of fatty acids of krill meal was as follow. The compositions of fatty acid were saturated fatty (SFA) acid 41.41%, monounsaturated fatty acid (MUFA) 21.69%, polyunsaturated fatty acid (PUFA) 36.89%, and p/s ratio was 0.89. The major fatty acids in all parts were eicosapentaenoic acid (EPA, 21.54%), palmitic acid (27.51%), oleic acid (13.35%) and docosahexaenoic acid (DHA, 12.42%). Especially, EPA and DHA were occupied 33.96% of polyunsaturated fatty acid. The mineral contents of krill meal were calcium 24477.21 mg $kg^{-1}$, sodium 14728.69 mg $kg^{-1}$, magnesium 6973.49 mg $kg^{-1}$, potassium 3981.67 mg $kg^{-1}$, iron 395.33 mg $kg^{-1}$ and manganese 5.74 mg $kg^{-1}$. The contents of major vitamin were retinol 86717.37 ${\mu}g$ RE, ${\beta}$-carotene 44.87 ${\mu}g$ RE, tocopherol 2.60 mg, pantothenic acid 1.61 mg, indicating that krill meal contains large amount of retinol and ${\beta}$-carotene.
