남극해 크릴 새우의 지방산조성과 무기질 및 비타민함량

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 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.
