Separating crustacean polar phospholipid compositions without emulsification
Fluorine being present in the exoskeleton of crustaceans, and especially krill represents a problem for using krill as a source for food, feed, food additives and/or feed additives. There has been developed a process for removing such fluorine from krill material by subjecting the krill to disintegration and to an enzymatic hydrolysis process prior to or simultaneously with a removal of the exoskeleton particles producing a fluorine-reduced product. Inherent in the disclosed process is the ability to process krill material with a high polar lipid content for producing superior quality, low fluorine, products suitable for the food and feed as well as the pharmaceutical, neutraceutical and cosmetic industry.
1. A method for preventing emulsification, comprising:
a) providing;
i) a proteinaceous crustacean material comprising polar phospholipids;
ii) a horizontal decanter centrifuge comprising an extended separation path, an inlet and an outlet;
b) feeding said proteinaceous crustacean material into said centrifuge; and
c) separating said proteinaceous crustacean material into a plurality of fractions at a force ranging between 5,000-10,000×g without said horizontal decanter centrifuge creating an emulsion.
2. The method of claim 1 , wherein said inlet and said outlet are at opposite ends of said centrifuge.
3. The method of claim 1 , wherein said feeding is performed at said inlet.
4. The method of claim 1 , further comprising the step of collecting said plurality of fractions from said outlet.
5. The method of claim 1 , wherein said plurality of fractions are layered within said centrifuge during said separating.
6. The method of claim 1 , wherein one of said plurality of fractions comprises a phospholipid-protein complex fraction.
7. The method of claim 1 , wherein one of said plurality of fractions comprises a lean hydrolysate fraction comprising protein.
8. The method of claim 1 , wherein one of said plurality of fractions comprises a neutral lipid fraction.
9. The method of claim 1 , wherein said proteinaceous crustacean material is a low fluoride krill material as compared to conventional krill meal.
10. The method of claim 1 , wherein said proteinaceous crustacean material comprises an enzymatically hydrolyzed proteinaceous krill material.
11. The method of claim 1 , wherein said separating substantially removes a carapace of said proteinaceous crustacean material.
12. The method of claim 1 , wherein said proteinaceous crustacean material is a proteinaceous krill material.
