This type of raw material can provide valuable contributions of protein and fat with the correct nutritional composition.
However, it will also introduce specific issues connected with the existence of some chitin, wax esters/triglycerides, phospholipids, heavy metals/environmental toxins, water-soluble components and natural astaxanthin, which can be of particular interest to study the significance of in a commercial context.
Typically high levels of phospholipids and natural pigments found in krill and Calanus finmarchicus create challenges relating to the effective handling of oxidation-related issues and necessitates the generation of new knowledge relating to oxidation, the use of antioxidants and utilisation of synergy effects between different water and fat-soluble components with antioxidant properties.
Documentation of the added value of water-soluble compounds in the stickwater lays the foundation for developing biotechnological methods to increase the yield of krill based on filtering, enzyming or other suitable technology.
Relevant issues
- Develop new production conditions for plankton
- Document the added value of fat and pigments from Antarctic krill
- Document the nutritional effect of krill meal
- Develop effective methodology for stabilising of krill meal and krill oil
