METHOD FOR MAKING KRILL MEAL
A new method for krill meal production has been developed using a two step cooking process. In the first step the proteins and phospholipids are removed from the krill and precipitated as a coagulum. In the second stage the krill without phospholipids are cooked. Following this, residual fat and astaxanthin are removed from the krill using mechanical separation methods. A novel krill meal product with superior nutritional and technical properties is prepared.
1 . A process for extracting oil from krill comprising:
treating krill by mixing said krill with water at from about 25 to 80° C.;
drying the treated krill to provide a meal; and
extracting an oil containing phospholipids from said krill meal, wherein said oil comprises from about 1% to about 10% alkylacylphosphatidylcholine.
2 . The process of claim 1 , wherein said extracting comprises super critical fluid extraction.
3 . The process of claim 1 , wherein said krill is Euphausia superba.
4 . The process of claim 1 , wherein said krill is fresh.
5 . The process of claim 1 , wherein said krill oil comprises less than 10 ppm acetone.
6 . The process of claim 1 , wherein said krill oil comprises astaxanthin.
7 . The process of claim 1 , further comprising encapsulating said krill oil.
8 . A process for providing a dietary supplement comprising krill oil, said process comprising:
treating krill by mixing said krill with water at from about 25 to 80° C.;
drying the treated krill to provide a meal; and
extracting an oil containing phospholipids from said krill meal, wherein said oil comprises from about 1% to about 10% alkylacylphosphatidylcholine, and encapsulating said oil.
9 . The process of claim 8 , wherein said extracting comprises super critical fluid extraction.
10 . The process of claim 8 , wherein said krill is Euphausia superba.
11 . The process of claim 8 , wherein said krill is fresh.
12 . The process of claim 8 , wherein said krill oil comprises less than 10 ppm acetone.
13 . The process of claim 8 , wherein said krill oil comprises astaxanthin.
