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 at a temperature sufficient to denature the protein content of the krill and cause a first solid krill fraction and a 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. Krill oil compositions made by the process are also disclosed.
