Abstract To establish a theoretical foundation for efficient use for the squid liver, Oils of squid liver were investigated. high pressured Steam boiling law and friendly chromatograph/mass spectrography were used in this paper. Experiment results: added 1.5 times the volume of water for squid liver, the rate of fish oil extraction get the highest.The fish oil purification's condition is: to add volume fraction 80% phosphoric acid degum; to add sodium hydroxide depickle for the measure determined of thick fish oil's actual acid value; to add 20% activated charcoal decolorize; to treat 30min with revolving evaporation meter vacuum take off the smell of fish. After above disposal, the refined fish oil was light yellow, clear, with light fish smell, and the indexes reached SC/T3502-2000 fish oil level standards, including the main substances in EPA (16.9%) and DHA (21.2 per cent).
