오징어 가공부산물인 오징어내장을 효과적으로 사용하기 위한 방법으로 내장에서의 지방 추출 및 추출지방의 특성을 살펴보았다. 그 결과는 다음과 같다. 1) 원양산과 연안산의 총지방량은 각각 $30.50\%,;30.25\%$였으며 중성지질은 $96.24\%,;94.82\%$, 당지질은 $2.63\%,;2.85\%$, 인지질은 $2.37\%,;2.34\%$으로 나타났으며 콜레스테롤 함량은 $644mg\%,;1,224mg\%$를 각각 나타내었다. 2) 원양산 및 연안산 오징어의 주요 지방산은 모두 $C16;:;0,;C18;:;1omega9,;C20;:;4omega6,;C20;:;5omega3,;C22;:;6omega3$으로 나타났으며 중성지방질의 획분조성도 서로 유사하여 품종간의 유의차가 인정되지 않았으나 두군 모두 free fatty acid 함량이 가장 높은 $44.01\%,;39.63\%$를 각각 나타내었다. 3) 원양산의 분획별 주요지방산은 중성지질획분에서 $C16;:;0,;C18;:;1omega9,;C20;:;4omega6,;C20;:;5omega3,;C22;:;5omega3$, 인지질획분에서 $C16;:;0,;C16;:;1omega7,;C20;:;5omega3,;C22;:;6omega3$ 당지질획분에서 $C16;:;0,;C18;:;1omega9,;C20;:;5omega3,;C22;:;6omega3$으로 나타났다. 4) 연안산의 분획별 주요지방산은 중성지질획분에서 $C16;:;0,;C18;:;1omega9,;C20;:;4omega6,;C20;:;5omega3,;C22;:;6omega3$로 나타났으며 인지질획분에서는 $C16;:;0,;C18;:;1omega9,;C22;:;6omega3$로 당질획분에서 $C16;:;0,;C18;:;1omega9,;C22;:;6omega3$로 나타났다.
The oil content and composition of squid visera were determined to obtain data for utilization of this by-product. There was no significant difference in the glycolipid (GL) and phospholipid (PL) content in Illex argentinus and Todarodes pacificus, but neutral lipid (NL) was different (p<0.05). The viscera oil of I. argentinus contained $30.50\%$ total lipid which consisted of $96.24\%$ NL, $2.63\%$ GL, $2.37\%$ PL, and contained $644mg\%$ cholesterol. The viscera oil of T. pacificus contained $30.20\%$ total lipid which consisted of $94.82\%$ NL, $2.85\%$ GL, $2.34\%$ PL, and contained $1,224;mg\%$ cholesterol. The NL, GL and PL of viscera oil in I. argentinus mainly consist of triglyceride $(44.01\%)$, esterified steryl glycosides $(58.95\%)$ and phosphatidyl cholines $(32.36\%)$, respertively. Those of viscera oil in T. pacificus mainly consist of triglyceride $(39.63\%)$, monogalactosyl diglycerides $(51.67\%)$ and phosphatidyl cholines $(31.98\%)$, respectively. The major fatty acids of the viscera oil of I. argentinus and T. pacificus were C16 : 0, $C16;:;0,;C18;:;1omega9,;C20;:;4omega6,;C20;:;5omega3,;C22;:;6omega3$. In Illex argentinus, the fatty acids of NL mainly were $C16;:;0,;C18;:;1omega9,;C20;:;4omega6,;C20;:;5omega3,;C22;:;6omega3$. PL were $C16;:;1omega7,;C20;:;5omega3,;C22;:;6omega3$ and GL were $C18;:;1omega9,;C20;:;5omega3,;22;:;6omega3$. The major fatty acids of NL in T. pacificus were $C16;:;0,;C18;:;1omega9,;C20;:;4omega6,;C20;:;5omega3,;C22;:;6omega3$, PL were $C16;:;1omega7,;C20;:;5omega3,;C22;:;6omega3$, and GL were $C18;:;1omega9,;C20;:;5omega3,;C22;:;6omega3$.
