Abstract
The salted and dried mullet roe was manufactured by the conventional processing method. The processing conditions were the salting with soybean sauce of 10% NaCl, 1.2cm of thickness, 3m/sec of air velocity, 70% of RH and $20^{\circ}C$ of wind-drying temperature for 20 days. The fractional compositions of free and bound lipids were classified in neutral, Glyco - and phospholipids of the processed roe. The fatty acid content of glycolipids was measured during processing and storage. Major fatty acids of glycolipids were $C_{16:0},\;C_{18:1}\;and\;C_{18:2}$ whose total amount was 7.71mg/100mg occupying 77% of the total fatty acids of glycolipids. The ratio of unsaturated fatty acid to the saturated fatty acid of bound glycolipids was 2.09 and that of free glycolipids was as low as about 0.92. The rations of the polyenoic acids to the monoenoic acids were very low as 0.10-0.78. The essential fatty acids of bound glycolipids were 4.32mg/100mg and a very much decreased content of 1.46mg/100mg at 9 week storage time.
염건 숭어알은 전통적인 방법으로 제조하였다. 제조 조건들은 10%염농도의 간장에 염지하고 두께 1.2cm 정도로 압착하여 70% 습도에서 3m/sec의 풍속 및 $20^{\circ}C$에서 음건하였다. 가공돠 저장기간의 유리 및 결합지질을 분리하여 다시 중성, 당 및 인지질로 분획하였다. 주요구성 지방산은 $C_{16:0},\;C_{18:0},C_{18:1}과\;C_{18:2}$이며 합계량이 7.71mg/100mg 으로 당지질의 77% 정도 점유하였다. 불포화도는 결합당지질은 2.09로 유리당지질의 0.92와 차이가 많았다. 다가불포화 지방산비는 0.10-0.78로 낮았으며 필수지방산함량은 결합당지질의 신선어란 4.23mg/100mg에서 저장 9주째는 거의 소멸되었다.
