        Despite abundant nutritions, krill is barely used for human consumption. The objective of this study was to investigate the nutritional component and amino acid composition of krill and further utilizes it for food resource. Proximate compositions of krill meal were consisted of crude protein 58.85%, ash 13.89%, crude fat 12.45%, carbohydrate 11.01% and moisture 3.80%. The amount of total amino acid was 54.74 g%, and the major amino acids were glutamic acid (7.71 g%), aspartic acid (6.20 g%), leucine (4.72 g%), lysine (4.41 g%), arginine (6.49 g%) and alanine (3.25 g%), respectively. Total essential amino acid content was 21.87%, and the major amino acids were leucine (4.72 g%), lysine (4.41 g%) and isoleucine (2.90 g%), respectively. Content of total free amino acid in krill meal was 20224.30 mg/kg, and the major free amino acids were taurine (4501 mg/kg), arginine (3130.60 mg/kg), proline (2302.90 mg/kg), alanine (2088.10 mg/kg), glycine (1606.40 mg/kg) and lysine (1197.40 mg/kg). Especially, taurine was the most abundant of all free amino acids. Thus, these data indicate that krill seems to be abundant protein source food.

        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 μg RE, β-carotene 44.87 μg RE, tocopherol 2.60 mg, pantothenic acid 1.61 mg, indicating that krill meal contains large amount of retinol and β-carotene.
