Abstract: Fluorine being present in the exoskeleton of crustaceans, and especially krill represents a problem for using krill as a source for food, feed, food additives and/or feed additives. There has been developed a process for removing such fluorine from krill material by subjecting the krill to disintegration and to an enzymatic hydrolysis process prior to or simultaneously with a removal of the exoskeleton particles producing a fluorine-reduced product. Inherent in the disclosed process is the ability to process krill material with a high polar lipid content for producing superior quality, low fluorine, products suitable for the food and feed as well as the pharmaceutical, neutraceutical and cosmetic industry.

Abstract: The present invention is related to methods of making crustacean oil compositions. In particular, the crustacean oil compositions are krill oil compositions. In some embodiments, the krill oil compositions are concentrated in phospholipids. These concentrated phospholipid krill oil compositions have a sufficient flowability to permit successful encapsulation at phospholipid concentrations that is currently unattainable in the art. Such phospholipid krill oil compositions are capable of encapsulation even though they may have a phospholipid concentration ranging between approximately 60%-99% and a viscosity ranging between 100,000-3,000,000 cP. Such concentrated phospholipid krill oil compositions may be created using a small molecule organic solvent/water extraction mixture and/or sub-critical or super-critical fluid extraction at low temperatures followed by a drying process to remove water and organic solvent (e.g., for example, ethanol).

Abstract: 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 CO2 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.
