한국산 은어의 지질성분에 관한 연구-1 총지질성분의 비교 = Studies on the Lipid Components in Sweetfish from Korea-1 Comparison of the contents of total lipid components

다국어 초록 (Multilingual Abstract)

This study was carried out to compare the difference of proximate composition and total lipid components by size and various tissues in sweetfish(Plecoglossus altivelis). Lipid contents of the small and large sweetfish in viscera were $43.2\%\;and\;52.8\%$, respectively. Total lipid contents of the small and large sweetfish were consisted of $3.84{\sim}46.90g/100g$ neutral lipid, $0.86{\sim}4.38g/100g$ phospholipid, respectively. In fatty acid compositions of total lipid, sweetfish showed higher content in saturates such as 16:0, 18:0($43.78{\sim}48.29\%$), and lower content in polyenes such as 18:2n-6, 22:6n-3($13.13{\sim}17.10\%$), and the large sweetfish was somewhat higher in ratio of polyenes compared with the small one. The major fatty acids were 16:0, 18:1n-9, 16:1n-7, 18:2n-6, 22:6n-3, 18:0 and 14:0, in order.
