Abstract
The invention discloses a new solvent-free process for obtaining phospholipids and neutral lipids enriched krill oils containing DHA and EPA poly-unsaturated fatty acids and astaxanthin. The process includes cooking fresh krill at high temperature—without agitation and or grinding; decanting the cooked krill for obtaining a partial de-fatted and de-watered solid and a liquid; squeezing the obtained solid to obtain a press liquid and a solid fraction; centrifuging the press liquid to obtain the phospholipids enriched krill oil; centrifuging of the decanter liquid obtained to obtain the neutral lipid enriched krill oil and stickwater.
