A method for recovering fish oil from aquatic biomass under cold conditions, the method comprising the steps of; providing an aquatic biomass; producing a minced aquatic biomass by mincing the aquatic biomass; providing an aqueous suspension of the minced aquatic biomass by mixing and/or homogenizing the minced aquatic biomass in an aqueous solution; adjusting the pH of said aqueous suspension to an extreme high pH or an extreme low pH; separating the aqueous suspension into a supernatant comprising a lower density emulsion fraction substantially comprising oil, aqueous solution and emulsified proteins, and a higher density fraction comprising substantially solubilized proteins, and optionally a pellet comprising collagenous components; collecting the lower density emulsion fraction; separating the lower density emulsion fraction into an oil phase and an aqueous phase; and collecting the oil from said oil phase.

The present invention describes a method and an automatic system for recovering protein powder meal, crude and pure omega-3 oil and purified distilled water from a mixture of animal tissue processed in a filter-drier-reaction tank. Animal tissue, for example fish, and organic solvent are directly or indirectly fed into the filter-drier-reaction tank. The filter-drier-reaction tank mixes, heats, and separates solid and heavy liquid portions of the mixture, the organic solvents are automatically recycled back in to the system after distillation. The solid portion is retained in the filter-drier-reaction tank and baked. Solid protein powder product (the protein powder meal) is thus recovered.

The present invention contemplates the creation of a low fluoride crustacean oil processed from a phospholipid-protein complex (PPC) formed immediately upon a crustacean (i.e., for example, krill) catch. Further, the crustacean oil may also have reduced trimethyl amine and/or trimethyl amino oxide content. The process comprises disintegrating the crustaceans into smaller particles, adding water, heating the result, adding enzyme(s) to hydrolyze the disintegrated material, deactivating the enzyme(s), removing solids from the enzymatically processed material to reduce fluoride content of the material, separating and drying the PPC material. Then, using extraction with supercritical CO.sub.2 or supercritical dimethyl ether, and/or ethanol as solvents, krill oil, inter alia, is separated from the PPC. In the extraction the krill oil can be separated almost wholly from the feed material.
