| 摘要 |
The invention provides a process for producing a food-grade fatty-acid extract from a sample of marine animal visceral material, especially squid visceral material, said process comprising: processing the sample to obtain an essentially neutral (non-polar) lipid fraction and an essentially polar lipid fraction; optionally refining one or both of the lipid fractions thus obtained; and recombining the two fractions, or portions thereof, to produce a mixture having the desired characteristics. In certain embodiments, the sample is processed using a polar solvent, preferably ethanol, as an entrainer in a supercritical fluid extraction procedure, preferably using carbon dioxide, to provide both neutral and polar lipid fractions. |
