## Abstract

Provided herein are methods of making emulsions comprising triglycerides and a marine peptides wherein the method is carried out in the substantial absence of an added emulsifier.

## Claims

### Claim 1

A method of making a stable emulsion from biological marine materials, the method comprising:
a) providing a biological marine material comprising triglycerides and marine peptides, and mixing the biological marine material with water to form a biological marine material mixture comprising the biological marine material and water;
b) heating the biological marine material mixture in the presence of a catalyst while stirring at a speed of 10 to 200 revolutions per minute to form a marine hydrolysate mixture comprising a hydrolysate of the marine peptides, the triglycerides, and the catalyst, wherein the marine hydrolysate mixture is in the form of an emulsion, and wherein the marine hydrolysate mixture comprises no more than 1% by weight an added emulsifier; and
c) inactivating the catalyst in the marine hydrolysate mixture.

### Claim 2 (depends on 1)

The method of claim 1, wherein the catalyst comprises a peptidase or a protease.

### Claim 3 (depends on 1)

The method of claim 1, wherein the biological marine material comprises fish, fish parts, crustaceans, crustacean parts, evertebrates, evertebrate parts, or combination thereof.

### Claim 4 (depends on 3)

The method of claim 3, wherein the biological marine material comprises fish, fish parts, or combination thereof.

### Claim 5 (depends on 3)

The method of claim 3, wherein the biological marine material comprises crustaceans, crustacean parts, or combination thereof.

### Claim 6 (depends on 1)

The method of claim 1, wherein the emulsion is homogeneous.

### Claim 7 (depends on 1)

The method of claim 1, wherein the inactivating comprises heating the marine hydrolysate mixture to a temperature greater than 85° C. for a period of at least 15 minutes.
