꽁치의 자연건조 기간 중 구성 지질과 구성 지방산의 함량 변화를 검토한 결과는 다음과 같다. 꽁치의 자연건조 중 Total lipid와 수분 함량은 점차 감소하였고 건조 기간 중의 지질의 산패도 검사에서 과산화가는 점차 증가하였고 산가와 TBA 값은 9일 이후에 급격히 증가하였다. Total lipid의 중성 지질, 인지질, 당지질 함량은 각각 95, 4, 2%이었고 중성지질 중 TG의 함량이 90% 이상이었으며 인지질의 함량은 PC가 45∼58% 함량이었고, PE가 27∼34% 전후의 함량을 나타내었다. 건조기간 중 Total lipid의 지방산 조성은 C_16:0, C_20:1, C_22:1, C_22:6의 함량이 대체로 높았고, 중성지질중의 지방산 함량은 C_20:1, C_22:1의 함량이 대체로 높았으며, 인지질 중의 지방산 함량은 C_22:6의 함량이 가장 높았다. 당지질 중의 지방산 조성에서 단일불포화지방산 함유량이 대체로 높았고 포화지방만 중 C_16:0함유량은 점차 증가하였으며 단일불포화지방산의 C_22:1함량은 점차 감소하였다. Triglyceride 중의 지방산 조성에서는 단일불포화지방산의 함유량이 높았고 그 중 C_20:1과 C_22:1함량은 점차 감소하는 것으로 나타났다.
The results which were examined changes in contents of constitutive lipid and fatty acid during the natural drying of Pacific Saury were as follows. During the natural drying of Pacific Saury, otal lipid and moisture contents gradually decreased. In the survey of rancidity degree extracted lipid of Pacific Saury, peroxide value was gradually increased, TEA and acid value were radically increased thereafter 9 days of drying. Neutral lipid, phospholipid and glycolipid contents of total lipid were 95%, 4% and 2%, respectively, and in the neutral lipid, content of TG was more than 90%, and in the phospholipid, contents of PC and PE were 45∼85%, 27∼34%, respectively. Fatty acid composition of total lipid was substantially higher in C_18:0 and C_20:1, C_22:1, C_22:6 contents and fatty acid composition of neutral lipid was higher in C_20:1, C_22:1, contents and fatty acid composition of phospholipid was the highest in C_22:6 content. In the fatty acid composition of glycolipid, monounsaturated fatty acid content has substantially higher, C_16:0 content was gradually increased in saturated fatty acid and C_22:1 content was gradually decreased in monounsaturated fatty acid. It showed that fatty acid composition of triglyceride has higher in monounsaturated fatty acid content and contents of C_20:1, C_22:1 was gradually decreased.
