| 摘要 |
The present invention relates to a method and equipment for extraction of lipid fractions from marine raw materials, such as fish and krill, whereby valuable components are preserved in the extracted material by performing the extraction process under an essentially inert atmosphere at transiently elevated temperatures and without the use of organic solvents. The process comprises supplying an inert gas, such as Nitrogen, to exclude oxygen, mechanical grinding of the raw material, high frequency treatment of the grinded material, separation of liquid and solid components by conventional means, and recovering a lipid rich fraction from the liquid component. |
