Abstract
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° 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.
