Abstract

The present invention provides improved processes for extracting and preparing lipids from biological sources for use in pharmaceuticals, nutraceuticals and functional foods.

First claim

The invention claimed is:

1. A desalted krill lipid composition comprising:
from about 30% to 50% w/w phospholipids;
from about 32% to 52% w/w triglycerides;

and wherein the composition has the following properties:
a) the composition comprises less than about 0.2% w/w inorganic salts;
b) the composition comprises less than about 2 ppm Cu ++ ; and
c) the composition comprises less than about 3 ppm total arsenic.

2. The composition of claim 1 , said composition further characterized in comprising from about 3% w/w to 13% w/w free fatty acids.

3. The composition of claim 1 , said composition further characterized in comprising from about 0.5% w/w to 5% w/w lysophospholipids.

4. The composition of claim 1 , said composition further characterized in comprising less than about 2 mg N/100 g.

5. The composition of claim 1 , said composition further characterized in comprising from about 0.01% to about 1% w/w ethyl esters.

6. The composition of claim 1 , said composition further characterized in having a conductivity of less than about 20 μS/cm when measured with 5% dry matter in 95% ethanol.

7. The composition of claim 1 , said composition further characterized in having a viscosity of from about 100 to 400 mPas at 25° C.

8. The composition of claim 1 , said composition further characterized in comprising from about 20 ppm to about 2000 ppm astaxanthin esters.

9. A krill phospholipid concentrate comprising:
from about 50% to 85% w/w phospholipids;
from about 5% to 35% w/w triglycerides;

and wherein the composition has the following properties:
(a) the composition comprises less than about 0.2% w/w inorganic salts; and
(b) the composition has a viscosity of from about 600 to 1600 mPas at 35° C.

10. The composition of claim 9 , said composition further characterized in comprising from about 2% w/w to 13% w/w free fatty acids, from about 0.5% w/w to 10% w/w lysophospholipids, less than about 2 mg N/100 g, less than about 2 ppm Cu ++ ; less than about 3 ppm total arsenic; from about 0.01% to about 1% w/w ethyl esters; less than about 100 ppm astaxanthin esters and having a conductivity of less than about 20 μS/cm when measured with 5% dry matter in 95% ethanol.

11. The composition of claim 9 , said composition further characterized in having a conductivity of less than about 20 μS/cm when measured with 5% dry matter in 95% ethanol.

12. The composition of claim 11 , said composition further characterized in comprising less than about 2 ppm Cu ++ and less than about 3 ppm total arsenic.

13. The composition of claim 12 , said composition further characterized in comprising less than about 2 mg N/100 g.

14. The composition of claim 9 , said composition further characterized in comprising less than about 2 mg N/100 g, less than about 2 ppm Cu ++ , less than about 3 ppm total arsenic, and in having a conductivity of less than about 20 μS/cm when measured with 5% dry matter in 95% ethanol.
