Organic solvent-free processes for obtaining krill oil compositions are disclosed. The processes include a) cooking krill in a cooker vessel for a time and temperature sufficient to denature the protein content of the krill and cause a first solid krill fraction and first liquid krill fraction to be formed while substantially avoiding emulsification of the first solid and first liquid krill fractions; b) removing the first solid and first liquid krill fractions from the cooker vessel at a temperature of at least about 90&#xb0; C.; c) separating the first solid fraction and the first liquid fraction; and d) obtaining krill oil with neutral enriched from the first liquid fraction, and e) by pressing of first solid fraction to obtain press liquid or a second liquid krill fraction for obtaining krill oil with phospholipids enriched krill oil, the separating and the obtaining steps being carried out without the use of organic solvents.

Solvent-free process for obtaining phospholipids and neutral enriched krill oils

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&#x2014;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.
