Abstract
The present invention contemplates the creation of a low fluoride oil processed from a phospholipid-protein complex (PPC) formed immediately upon a crustacean (i.e., for example, krill) catch. 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 and ethanol as solvents, inter alia krill oil is separated from the PPC. In the extraction the krill oil can be separated almost wholly from the feed material. The products have low fluoride content. The manufacturing costs in the extraction process are relatively low.
