Patent ID: 8609157

Claim:
A solvent-free method for producing Euphasia superba oil consisting essentially of: a) heating whole fresh Euphasia superba to a temperature sufficient for protein denaturation of the Euphasia superba while substantially avoiding emulsification to produce cooked Euphasia superba; b) separating the cooked Euphasia superba from step a) using a decanter to obtain a partially de-fatted and de-watered solid and a decanter liquid; c) squeezing the partially de-fatted and de-watered solid from step b) unto a screw press or screw conveyor to obtain a press liquid and a solid fraction; d) separating the press liquid from step c) to obtain Euphasia superba oil enriched in phospholipids; and e) separating the decanter liquid from step b) to obtain Euphasia superba oil enriched in neutral lipids wherein steps a) through e) are carried out while on board a boat at sea.
