Abstract: Squid liver was the raw material in this work, AS.1389 neutral protease was used to extract fish oil, extraction rate was choose as index, the best enzymatic technology was confirmed by single factors and surface response tests. And the fish oil extraction ratio, oil quality and fatty acid composition were system compared which was extracted by enzymatic and water. The result showed that the optimum condition of enzymatic technology was follows：liquid ratio was 1:1, pH was 6, the quantity of enzyme was 1340 U/g , temperature was 55℃ and hour was 4 h; Compared with water extraction, the enzymatic oil are higher extraction rate, lower peroxide value, better oil quality.
