Marine peptide emulsions

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.
