## Abstract

This invention provides a high quality soluble protein composition and the processes of making the same. According to the described methods, a non-pumpable broth may be converted into a pumpable broth by using a filtration means. The resulting compositions are shelf-stable, easy to use and have excellent nutritional values as compared to other protein products.

## Claims

### Claim 1

A method of making a pumpable composition, comprising:
(a) applying a starting composition to a filtration means, said filtration means having a pore size of 500 nanometers (nm) or smaller, said starting composition being prepared from an animal source,
(b) allowing the starting composition to pass through the filtration means, and
(c) collecting permeate that passes through said filtration means to obtain said pumpable composition,
wherein said composition obtained in step (c) is pumpable at refrigeration temperature, and wherein hydroxyproline constitutes less than 3% (w/w) of total amino acids in said pumpable composition obtained in step (c).

### Claim 2 (depends on 1)

The method of claim 1, wherein said pumpable composition obtained in step (c) has at least 50% (w/w) solids.

### Claim 3 (depends on 1)

The method of claim 1, wherein said pumpable composition obtained in step (c) has collagen concentration of 10% (w/w) or lower.

### Claim 4 (depends on 1)

The method of claim 1, wherein proline constitutes less than 7% (w/w) of total amino acids in said pumpable composition obtained in step (c).

### Claim 5 (depends on 1)

The method of claim 1, wherein glycine constitutes less than 11% (w/w) of total amino acids in said pumpable composition obtained in step (c).

### Claim 6 (depends on 1)

The method of claim 1, wherein said filtration means is selected from the group consisting of microfiltration, ultrafiltration, nanofiltration, reverse osmosis, and combination thereof.

### Claim 7 (depends on 1)

The method of claim 1, wherein said starting composition is subjected to a separation step before being applied to the filtration means, said separation step preceding step (a).

### Claim 8 (depends on 7)

The method of claim 7, wherein said separation step is carried out by centrifugation.

### Claim 9 (depends on 1)

The method of claim 1, wherein said pumpable composition obtained in step (c) has a water activity of 0.85 or lower.

### Claim 10 (depends on 1)

The method of claim 1, wherein said pumpable composition obtained in step (c) is shelf-stable.

### Claim 11 (depends on 1)

The method of claim 1, wherein enzyme is added to said starting composition before being applied to the filtration means.

### Claim 12 (depends on 1)

The method of claim 1, wherein salt is added to said starting composition before being applied to the filtration means.

### Claim 13 (depends on 1)

The method of claim 1, further comprising a step (d) to remove sodium from the pumpable composition obtained in step (c).

### Claim 14 (depends on 13)

The method of claim 13, wherein the level of sodium is reduced by at least 50% in step (d).

### Claim 15 (depends on 1)

The method of claim 1, wherein the composition obtained in step (c) is pumpable at 4° C.

### Claim 16 (depends on 1)

The method of claim 1, wherein the color of the pumpable composition obtained in step (c) is substantially different from the color of the starting composition.

### Claim 17 (depends on 1)

The method of claim 1, wherein the color of the pumpable composition obtained in step (c) is substantially lighter than the color of the starting composition.

### Claim 18 (depends on 1)

The method of claim 1, wherein said filtration means has a pore size of 100 nm or smaller.

### Claim 19 (depends on 1)

The method of claim 1, wherein said pumpable composition obtained in step (c) has a viscosity of 50,000 cP or lower.
