The present disclosure 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 C02 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. Particularly disclosed is a crustacean oil composition, comprising phospholipids and where said phospholipids comprise phosphatidylethanolamine in the range of 1.4 to 4.9 w/w,resulting in a clear red colour due to a minimal oxidation, and/or degradation and formation of dark/brown colour, wherein said phospholipids are between 39-52 wt%, wherein said phospholipids comprise at least 2 wt % phospatidylethanolamine, 65 wt% phosphatidylcholine and maximum 2.4 wt% lysophasphatidylcholine. |
