염건 숭어알을 10% 염농도의 간장에 침지하고 1.2cm 두께로 압착하여 2$0^{circ}C$에서 3m/sec 풍속으로 음건하여 제조하였다. 제품의 지질을 중성지질, 당지질 및 인지질로 분획하고 유리인지질은 9.3mg/100mg, 결합인지질은 13.0mg/100mg 함유하였으며 가공과 저장중에 빠른 속도로 감소하였다. 인지질을 구성하는 주요 지방산은 $C_{l6:0}$, $C_{20:0}$, $C_{16:1}$, $C_{l8:2}$와 $C_{20:5}$였으며, 이들 지방산의 함량은 6.64mg/100mg으로 총인지질 지방산의 72%를 점유했다. 불포화도는 유리 인지질에서 1.53이었고 결합 인지질에서는 0.34로 낮았다. 그러나 결합 인지질의 불포화도는 신선할 때는 1.04이었고 6주후에는 0에 가깝고, 필수지방산도 3.85mg/100mg으로 전체 필수지방산의 75% 정도이었으나 가공중에 거의 파괴되었다.다.다.다.
Mullet roe was salted and dried by the conventional processing method. Mullet roe was first salted with soybean sauce containing 10% NaCl and then pressed down to be a 1.2cm of thickness. It was dried at 2$0^{circ}C$ under 3m/sec of aeration for 20 days. The lipids of the processed roe were fractionated by free and bound phospholipids. The contents of free and bound phospholipids were 9.30mg/100mg and 13.0mg/100mg respectively. The content of bound lipids were rapidly decreased than that of free fatty acids during processing and storaging. The major fatty acids of phospholipids were $C_{l6:0}$, $C_{20:0}$, $C_{16:1}$, $C_{l8:2}$ and $C_{20:5}$ whose contents were 6.64mg/100mg that occupied 72% of the total phospholipids. The ratio for the unsaturated fatty acids to the saturated ones of free phospholipids in fresh roe was 1.53 and it was decreased down to 0.34 in 9 weeks of storage. But the ratio of bound phospholipids was 1.04 of fresh roe and zero in 6 weeks. The content of essential fatty acids in bound phospholipids was 3.85mg/100mg occupying 75% of total essential fatty acids of the fresh roe, but they were totally destroyed during processing.g.g.g.
