The invention relates to a new solvent-free process for simultaneously obtaining phospholipids-enriched krill oil and neutral lipid enriched-krill oil containing DHA and EPA poly-unsaturated fatty acids and astaxanthin and krill meal. The process includes preheating fresh minced krill followed by melting of the lipids using live steam injection to obtain a press liquid and a solid fraction; centrifuging the press liquid to obtain a phospholipids-enriched emulsion phase; evaporating the water of the emulsion using a thin film evaporator to obtain phospholipids-enriched krill oil; centrifuging the resulting decanter liquid to obtain neutral lipids enriched krill oil and stickwater.

In accordance with the invention, it was found, surprisingly, that a polyunsaturated fatty acids (PUFAs)-comprising biomass with other feedstuff components can be extruded at a low energy input of 12-28 Wh/kg to give an extrudate with a very high oil load capacity.

A method of recovering one or more insoluble oils from a liquid source using one or more membrane or membrane contactors, comprising the steps of: pumping the liquid source comprising the one or more oils to the membranes or membrane contactors, contacting the liquid source with a first surface of the membrane or membrane contactors, coalescing the one or more oils within the liquid source onto the first surface of the membrane contactors, pumping one or more recovery fluids through the membrane or membrane contactors in contact with the second surface of the membrane or membrane contactors, and removing a first stream of oil coalesced from the second surface of the membranes or membrane contactors.

Methods for obtaining corn oil from milled corn germ (e.g., dry milled corn germ), involving adding water, at least one acidic cellulase, at least one acidic protease, and at least one phytase to milled corn germ to obtain corn oil.

Provided herein are microalgae of a Thraustochytrid and a method for preparing bio-oil using the same, and more particularly, Aurantiochytrium sp. LA3 (KCTC12685BP) having bio-oil producibility, and a method of preparing bio-oil, particularly bio-oil having a content of omega-3 unsaturated fatty acids of 30% by weight or more based on total fatty acids, characterized by culturing the microalgae. The microalgae Aurantiochytrium sp. LA3 (KCTC12685BP) described herein has a rapid sugar consumption rate when being cultured using glucose as a carbon source, has a high oil content, allows cells to be cultured at a high concentration, and allows oil to be obtained in high productivity and a high yield, and thus, may produce bio-oil more economically and environmentally friendly.
