It is provided a process for generating enriched phospholipid compositions from raw krill oil, where such processes may be batchwise, continuous, of include both batchwise steps and continuous steps. The present technology provides high quality enriched phospholipid compositions from such methods. Moreover, the continuous process provides a significantly higher throughput compared to a batch process while concurrently providing products of equal or greater quality.

A preparation comprising krill oil and phospholipids. Methods of treatment comprising administering the same.

The invention provides a gelated mono-nuclear microencapsulate comprising a lipid emulsion core encapsulated within a gastro-resistant, ileal sensitive, polymerized chitosan membrane shell, wherein the lipid emulsion core comprises denatured or hydrolysed protein and carbohydrate. In one embodiment of the invention, the emulsion is a micro-emulsion, and typically comprises a surfactant and a co-surfactant or at least two carbohydrates, for example sucrose and a maltodextrin. In one embodiment of the invention, the lipid is a marine derived lipid such as fish oil, krill oil, or nutraceutical fatty acids. In other embodiment, the lipid is a fatty acid such as DHA or ARA, or a lipid derived from seeds, nuts or eggs.

This invention discloses new krill oil compositions characterized by having high amounts of phospholipids, astaxanthin esters and/or omega-3 contents. The krill oils are obtained from krill meal using supercritical fluid extraction in a two stage process. Stage 1 removes the neutral lipid by extracting with neat supercritical CO.sub.2 or CO.sub.2 plus approximately 5% of a co-solvent. Stage 2 extracts the actual krill oils by using supercritical CO.sub.2 in combination with approximately 20% ethanol. The krill oil materials obtained are compared with commercially available krill oil and found to be more bioeffective in a number of areas such as anti-inflammation, anti-oxidant effects, improving insulin resistances and improving blood lipid profile.

The present invention encompasses oils that have anti-inflammatory or resolution-stimulating activity that contain or are enriched with Specialized Proresolving Mediators (SPM) or SPM precursors, which originate from an oil obtained from organisms containing long chain omega-3 polyunsaturated fatty acids, such as fish, crustaceae, algae, and mollusks. The invention also encompasses a method for the production of these oils, and the utilization of the oils for nutritional supplements, pharmaceutical formulations, and cosmetic formulations, which can be employed for treating an inflammatory condition.
