Claims

1. A process for producing an active unfertilized salmon egg fraction comprising:

milling unfertilized salmon eggs between two surfaces, at least one of which is a milling surface, wherein said surfaces have a space there between so that said unfertilized salmon eggs are crushed when passed between said surfaces to provide an unfertilized salmon egg homogenate;

separating an active fraction from said unfertilized salmon homogenate by centrifugation to provide an active fraction comprising about 100 to 380 mg/ml protein in an aqueous solution.

2. The process of claim 1, wherein said milling surface comprising cutting elements.

3. The process of claim 1, wherein said cutting elements comprise knurls.

4. The process of claim 1, wherein said surfaces are cylindrical and rotate.

5. The process of claim 1, wherein said surfaces are separated by about 0.1 to 2.0 mm.

6. The process of claim 1, wherein said separating comprising centrifugal separation.
