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.
